Description

Measuring method and measuring device

This application claims the priority of the Chinese patent application filed with the China Patent Office on February 16, 2023, with application number 202310153370.8 and application name “Measurement Method and Measuring Device”, the entire contents of which are incorporated by reference into this application.

Technical Field

The embodiments of the present application relate to the field of communication technology, and in particular, to a measurement method and a measurement device.

Background Art

With the development of communication technology, the mobility of terminal devices has been enhanced. At present, the relevant protocols of the 3rd Generation Partnership Project (3GPP) define that when the terminal device is in a connected state, it is necessary to perform radio resource management (RRM) L3 mobility management, which mainly involves the measurement of searching for the same-frequency, different-frequency and different-system neighboring cells. The terminal device needs to determine the new neighboring cell and complete the reporting of the measurement results within the corresponding time requirements, and perform the corresponding mobility management.

Among them, the process of measuring the terminal device involves measuring radio resource control (RRC) reconfiguration, bandwidth part (BWP) switching or cell switching. When the same frequency point of the terminal device changes, it takes a relatively long time to obtain the measurement results of the same frequency and different frequency neighboring cells of the terminal device. For example, in the DXR1.28 scenario, the delay in obtaining the cell information of the same frequency point exceeds about 10s, and the delay has a great impact on the overall performance of the network.

Therefore, there is an urgent need for a method to reduce the time of obtaining neighboring area measurement results of a terminal device and improve the mobility performance of the terminal device.

Summary of the invention

The embodiment of the present application provides a measurement method and a measurement device, which can reduce the time of obtaining the neighboring area measurement results of the terminal device and improve the mobility performance of the terminal device in a scenario where the same frequency point of the terminal device changes.

In a first aspect, a measurement method is provided, which can be performed by a terminal device, or can also be performed by a chip or circuit of the terminal device, and this application does not specifically limit this. For ease of description, the communication device in this application will be described by taking the terminal device as an example.

The method includes:

The co-frequency point of the terminal device is switched from the second frequency point to the first frequency point, and the first frequency point is the heterofrequency point of the terminal device before the co-frequency point switching; the terminal device multiplexes the first information into the co-frequency neighboring area information list of the first frequency point after the co-frequency point switching; the terminal device multiplexes the second information into the heterofrequency neighboring area information list of the second frequency point after the co-frequency point switching, wherein the first information is the neighboring area information of the first frequency point before the co-frequency point switching of the terminal device, and the second information is the neighboring area information of the second frequency point before the co-frequency point switching of the terminal device.

According to the method provided by the present application, in the scenario where the co-frequency point of the terminal device changes, the terminal device can directly reuse the neighboring cell information of the corresponding frequency point before the co-frequency point changes. Compared with the prior art, when the co-frequency point of the terminal device changes, the terminal device does not need to search for the neighboring cell corresponding to the changed frequency point and obtain the SSB index, thereby shortening the delay of the terminal device in reporting the neighboring cell measurement results and improving the overall performance of the network.

It should be understood that the first frequency point in the present application may include one or more frequency points, and the second frequency point may include one or more frequency points. The first information may be the neighboring area information of the first frequency point (one or more frequency points) before the terminal device switches to the same frequency point, and the second information may be the neighboring area information of the second frequency point (one or more frequency points) before the terminal device switches to the same frequency point.

In combination with the first aspect, in some possible implementation methods, the second frequency point may include the co-frequency point and heterofrequency point of the terminal device. When the co-frequency point of the terminal device is switched, that is, the co-frequency point of the terminal device is switched from the second frequency point to the first frequency point, the co-frequency point in the second frequency point is updated to the heterofrequency point of the terminal device. After the co-frequency point is switched, in the measurement configuration information obtained by the terminal device, the heterofrequency point in the second frequency point before the switch may still be the heterofrequency point of the terminal device after the switch. In the process of information multiplexing, the co-frequency point neighboring area information of the terminal device in the second frequency point before the switch is multiplexed into the heterofrequency point neighboring area information list of the frequency point after the switch, and the heterofrequency point neighboring area information of the terminal device in the second frequency point before the switch is multiplexed into the heterofrequency point neighboring area information list of the frequency point after the switch.

In conjunction with the first aspect, in some possible implementations, the neighboring cells of the first frequency point include the first cell, the neighboring cells of the second frequency point The area includes a second cell, and the first cell and the second cell satisfy a first condition, wherein the first condition includes: within a first time period, the terminal device completes cell measurement reporting for the first cell and the second cell or the terminal device completes identification of the first cell and the second cell, and the signal strength of the first cell and the second cell relative to the terminal device is greater than or equal to a first threshold.

Based on the above technical solution, in the scenario where the co-frequency point of the terminal device changes, the neighboring cells of the first frequency point and the neighboring cells of the second frequency point must meet the first condition (or the condition of known neighboring cells), and the terminal device completes the cell measurement report of the first cell and the second cell or completes the cell identification of the first cell and the second cell within the first time period, and the signal strength of the first cell and the second cell relative to the terminal device is greater than or equal to the first threshold. When the terminal device determines that the first cell and the second cell meet the first condition, the terminal device directly reuses the neighboring cell information of the corresponding frequency point, thereby reducing the delay caused by the co-frequency point change of the terminal device.

It should be understood that the adjacent cells of the first frequency point and the second frequency point include one or more cells, that is, the first cell and the second cell both represent a type of cell, that is, the first cell represents the adjacent cells of the first frequency point, and the second cell represents the adjacent cells of the second frequency point. There is no limitation on the number of adjacent cells for the first cell and the second cell.

It should also be understood that the first threshold may be pre-configured by the system, or determined by the terminal device itself, or indicated by the network device to the terminal device, and this application does not make any specific limitation on this.

In combination with the first aspect, in some possible implementation methods, the first information includes measurement information and/or frequency information of the first cell, and the second information includes measurement information and/or frequency information of the second cell, wherein the measurement information includes one or more of the following: timing information, measurement value, synchronization signal block index SSB index, automatic gain control AGC gear information.

Based on the above technical solution, the terminal device multiplexes the first information into the same-frequency neighboring area information list of the first frequency after the same-frequency switching, and the terminal device multiplexes the second information into the different-frequency neighboring area information list of the second frequency after the same-frequency switching. The first information includes the information of the first cell when the first frequency is the different-frequency point of the terminal device (or the neighboring area information of the first frequency), and the second information includes the information of the second cell when the second frequency is the same-frequency point of the terminal device (or the neighboring area information of the second frequency). The information of the first cell and the information of the second cell may include one or more of the timing information, the measurement value, the synchronization signal block index SSB index, and the frequency information. The terminal device can directly reuse the original neighboring area information without searching and obtaining the SSB index, thereby reducing the delay caused by the same-frequency point change of the terminal device.

In combination with the first aspect, in some possible implementations, the first time period is a time period before the same frequency point of the terminal device switches from the second frequency point to the first frequency point.

It should be understood that the first time period can be any continuous time before the co-frequency point of the terminal device is switched from the second frequency point to the first frequency point. That is, before the co-frequency point of the terminal device is switched from the second frequency point to the first frequency point, the terminal device completes the cell measurement report of the first cell and the second cell or completes the cell identification of the first cell and the second cell, and the signal strength of the first cell and the second cell relative to the terminal device is greater than or equal to the first threshold.

In conjunction with the first aspect, in some possible implementations, the first condition further includes: the first measurement configuration parameter is the same as the second measurement configuration parameter, and the first measurement configuration parameter and the second measurement configuration parameter both include at least one of the following:

Frequency information, cell identification information, synchronization signal block SSB information,

Among them, the first measurement configuration parameter is the measurement configuration parameter of the first frequency point and the second frequency point before the co-frequency point of the terminal device is switched from the second frequency point to the first frequency point, and the second measurement configuration parameter is the measurement configuration parameter of the first frequency point and the second frequency point after the co-frequency point of the terminal device is switched from the second frequency point to the first frequency point.

Based on the above technical solution, the first condition that the first cell and the second cell need to meet also includes: the first measurement configuration parameter is the same as the second measurement configuration parameter. That is, before the same frequency point of the terminal device is switched, the measurement parameters of the first frequency point and the second frequency point are the same as the measurement configuration parameters of the first frequency point and the second frequency point after the same frequency point of the terminal device is switched. The measurement configuration parameter may include one or more of the frequency point information, the cell identification information, and the synchronization signal block SSB information.

In a second aspect, a measurement method is provided, the method comprising: a terminal device adds a first frequency point as a co-frequency point of the terminal device; the terminal device multiplexes first information into a co-frequency neighboring area information list of the first frequency point added as the co-frequency point of the terminal device, wherein, before the terminal device adds the first frequency point as the co-frequency point of the terminal device, the first frequency point is a hetero-frequency point of the terminal device, the co-frequency point of the terminal device includes a second frequency point, and the first information is the neighboring area information when the first frequency point is a hetero-frequency point of the terminal device.

According to the method provided in the present application, the terminal device can add a certain different frequency point as its own same frequency point, that is, the same frequency point of the terminal device can include one or more. Similarly, the terminal device can directly reuse the neighboring area information of the different frequency point into the same frequency neighboring area information list of the frequency point after it is added as the same frequency point, without the need for the terminal device to measure the neighboring area corresponding to the frequency point and obtain the SSB index, thereby reducing the delay required for adding the same frequency point of the terminal device and improving the overall performance of the network.

In conjunction with the second aspect, in some possible implementations, the neighboring cell of the first frequency point includes the first cell, and the first cell satisfies the A condition, wherein the first condition includes: within a first time period, the terminal device completes cell measurement reporting for the first cell or the terminal device completes identification of the first cell, and the signal strength of the first cell relative to the terminal device is greater than or equal to a first threshold.

Based on the above technical solution, in a scenario where the co-frequency point of the terminal device changes (for example, a scenario where the terminal device adds a co-frequency point), the adjacent cell of the first frequency point meets the first condition (or the condition of a known adjacent cell), the terminal device completes the cell measurement report of the first cell or completes the cell identification of the first cell within the first time period, and the signal strength of the first cell relative to the terminal device is greater than or equal to the first threshold. The terminal device determines that the first cell meets the first condition, and the terminal device directly reuses the adjacent cell information when the first frequency point is a different frequency point of the terminal device, thereby improving the overall performance of the network.

In combination with the second aspect, in some possible implementation methods, the first information includes measurement information and/or frequency information of the first cell, and the measurement information of the first cell includes one or more of the following: timing information, measurement value, synchronization signal block index SSB index, automatic gain control AGC gear information.

Based on the above technical solution, the terminal device multiplexes the first information into the same-frequency point and adds it to the same-frequency point to become the same-frequency point of the terminal device. The first information includes the information of the first cell when the first frequency point is a different frequency point of the terminal device (or called the neighboring cell information of the first frequency point), and the information of the first cell may include one or more of the timing information, the measurement value, the synchronization signal block index SSB index, and the frequency point information. The terminal device can directly reuse the neighboring cell information when the first frequency point is a different frequency point, without the need for searching and SSB index acquisition, thereby improving the overall performance of the network.

In combination with the second aspect, in some possible implementations, the first time period is a time period before the terminal device adds the first frequency point as a co-frequency point of the terminal device.

It should be understood that the first time period can be any continuous time before the terminal device adds the first frequency point as the same frequency point. That is, when the first frequency point is an inter-frequency point of the terminal device, the terminal device completes the cell measurement report of the first cell or completes the cell identification of the first cell, and the signal strength of the first cell relative to the terminal device when the first frequency point is an inter-frequency point of the terminal device and the first frequency point is a same frequency point of the terminal device is greater than or equal to the first threshold.

In the embodiments of the present application, the device that realizes the function of the terminal device can be the terminal device, or it can be a device that supports the terminal device to realize the function (such as a chip system in the terminal device).

The network device in the embodiments of the present application may be a device for communicating with a terminal device. The network device may be a base station (base transceiver station, BTS) in a global system of mobile communication (GSM) system or code division multiple access (CDMA), or a base station (nodeB, NB) in a wideband code division multiple access (WCDMA) system, or an evolved base station (evolutional nodeB, eNB or eNodeB) in an LTE system, or a wireless controller in a cloud radio access network (CRAN) scenario, or the network device may be a relay station, an access point, an in-vehicle device, a wearable device, or a new network device that may appear in a future 5G network or a network device in a future evolved PLMN network, etc., and the embodiments of the present application are not limited thereto.

FIG1 is a schematic diagram of a network architecture of a communication system provided in an embodiment of the present application.

Among them, some scenarios in the embodiments of the present application are described by taking the scenarios in the communication system shown in Figure 1 as an example. The method in the embodiments of the present application can also be applied to other mobile communication systems, and the corresponding names can also be replaced by the names of corresponding functions in other mobile communication systems, which is not specifically limited in the present application.

As shown in FIG. 1 , the communication system includes a terminal device 110 , a network device 120 , a network device 130 and a network device 140 .

It should be understood that in a communication system, the communication system is divided into areas, and each communication area should contain one or more network devices. The area covered by the network device signal is the cell corresponding to the current network device. The network device can provide services for one or more terminal devices in the corresponding cell. The embodiment of the present application does not limit the number of network devices and terminal devices in the communication system.

As shown in FIG1 , the cell corresponding to the network device 120 is the source cell, the cell corresponding to the network device 130 is the target cell, and the cell corresponding to the network device 140 is the adjacent cell (or called the neighboring cell). The terminal device 110 initially establishes a connection with the network device 120. Due to the movement of the terminal device 110, the service quality of the source cell relative to the terminal device 110 is reduced until the source cell cannot meet the communication quality requirements of the terminal device 110. At this time, the terminal device 110 needs to switch the cell. During the cell switching, the terminal device 110 will maintain a connection with both the network device 120 and the network device 130 until it receives a signaling sent by the network device 130, disconnects the connection with the network device 120, releases the source cell to complete the cell switching, that is, switches from the source cell to the target cell.

In order to facilitate understanding of the technical solutions in the embodiments of the present application, some terms in the embodiments of the present application are explained below so that those skilled in the art can understand them.

1. Bandwidth part (BWP)

A BWP is composed of a set of consecutive physical resource blocks (PRBs). These PRBs are selected from a set of consecutive common resource blocks (CRBs). Each BWP can be a different numerology. Different numerologies correspond to different subcarrier spacing, symbol duration, and cyclic prefix.

Among them, the UE can configure up to 4 BWPs in uplink transmission UL/downlink transmission DL, among which only one BWP is in an activated state at each specific moment. According to the operation of BWP in the 3GPP protocol, the BWP can be selected or switched in the following ways.

(1) Select or switch BWP through RRC signal

(2) Activate BWP via the BWP indicator in DCI 0_1 (UL) and DCI 1_0 (DL)

(3) Switching BWP through the BWP deactivation timer

(4) Select or switch BWP through MAC CE

By using the above-mentioned methods, the BWP can be selected or switched. Among them, a specific BWP will become activated according to various situations in call processing (ie, changes in user service requirements).

2. Radio resource management (RRM)

RRM measurement can also be called mobility measurement. In LTE communication system, RRM measurement is based on the measurement of common reference signal (CRS), including reference signal received power (RSRP), reference signal received quality (RSRQ) and signal to noise and interference ratio (SINR). In NR communication system, RRM measurement includes two types: measurement based on synchronization signal block (SSB) and measurement based on channel state information (CSI-RS). If it is based on SSB measurement, then RRM measurement includes the measurement of synchronization signal based reference signal received power (SS-RSRP), synchronization signal based reference signal received quality (SS-RSRQ) and synchronization signal based signal to noise and interference ratio (SS-SINR). If it is based on CSI-RS measurement, then RRM measurement includes the measurement of CSI-RSRP, CSI-RSRQ and CSI-SINR.

RRM measurement, such as L3RSRP measurement, is divided into intra-frequency measurement, inter-frequency measurement and inter-system measurement. Intra-frequency measurement means that the measured cells are on the same carrier. Inter-frequency measurement or inter-system measurement means that the measured cells are not on the same carrier.

In the prior art, when the service signal quality of the source service cell does not meet the requirements of the terminal device due to the movement of the terminal device, the terminal device needs to select a target cell with better signal quality to provide high-quality communication services for the terminal device.

According to the differences in the frequency bands between the serving cell and the target neighboring cell, the cell switching can be divided into intra-frequency switching and inter-frequency switching. Intra-frequency switching can be used to indicate that the target cell and the current serving cell use the same RF carrier frequency; inter-frequency switching can be used to indicate that the target cell and the current serving cell use different RF carrier frequencies.

When the terminal device is in a connected state, it is necessary to perform RRM L3 mobility management, which involves searching and measuring the same-frequency, different-frequency and different-system neighboring cells. The terminal device needs to discover new neighboring cells and report the measurement results within the corresponding time requirements, and perform corresponding mobility management after the measurement results are reported. The measurement process of the terminal device mainly involves measuring RRC reconfiguration, BWP switching and cell switching.

In the prior art, after the BWP of the terminal device switches, the SSB frequency of the adjacent cell changes. The definition of the terminal device identifying a new cell in the current protocol includes the time required for searching, measuring, and obtaining the SSB index.

Or, the original SSB frequency #0 of the terminal device is the same frequency point, and due to the BWP switching of the terminal device, the SSB frequency #0 is no longer the same frequency point of the terminal device. Among them, if the measurement object configuration still exists, the terminal device will measure the acquisition delay of the hetero-frequency neighboring area according to the hetero-frequency measurement, which includes the time required for search, measurement and SSB index acquisition.

It is understandable that when the co-frequency point of the terminal device changes, the terminal device needs to further search, measure and SSB index to obtain the measurement results of the co-frequency and hetero-frequency neighboring cells, which leads to a longer acquisition time for the terminal device and a greater impact on the mobility switching performance of the terminal device.

Based on the above technical problems, an embodiment of the present application provides a measurement method, which avoids the time for terminal device search and SSB index acquisition in the scenario where the same frequency point changes, speeds up the reporting of the measurement results of the terminal device, and improves the performance of terminal device mobility switching.

FIG. 2 is a schematic flowchart of a measurement method provided in an embodiment of the present application.

It should be noted that the communication device in Figure 2 specifically takes the terminal device as an example to illustrate in detail the measurement method provided in this application.

As shown in FIG2 , the method comprises the following steps:

S201, the same frequency point of the communication device (for example, terminal equipment) is switched from the second frequency point to the first frequency point.

Among them, before the terminal device switches to the same frequency point, the first frequency point is the different frequency point of the terminal device, and the second frequency point is the same frequency point of the terminal device.

It should be understood that the scenario in which the co-frequency point of the terminal device changes may be the change in the co-frequency point of the terminal device caused by the activation of the BWP switching of the terminal device, or the change in the service frequency point caused by the cell switching corresponding to the terminal device, or the addition of the service frequency point in the carrier aggregation CA scenario, etc., which is not specifically limited in this application. Among them, there may be scenarios in the future that cause the co-frequency point of the terminal device to change, and the method shown in Figure 2 of this application can be applied.

S202, the communication device multiplexes the first information into the same-frequency point neighboring area information list of the first frequency point after the same-frequency point switching.

Among them, the first information is the neighboring area information of the first frequency before the terminal device switches to the same frequency, or it can be called the hetero-frequency neighboring area information of the first frequency.

Specifically, when the co-frequency point of the terminal device is switched from the second frequency point to the first frequency point, the terminal device can multiplex the neighboring area information when the first frequency point is the hetero-frequency point of the terminal device into the neighboring area information list when the first frequency point after switching is the co-frequency point of the terminal device.

It should be understood that the first information is multiplexed into the co-frequency point neighbor information list of the first frequency point after switching, or it can be said that the first information is inherited to the co-frequency point neighbor information list of the first frequency point after switching, or it can be said that the first information is updated to the co-frequency point neighbor information list of the first frequency point after switching. That is, the terminal device stores the first information in the co-frequency point neighbor information list of the first frequency point after switching, and can be directly used by the terminal device.

In a possible implementation, the neighboring cell of the first frequency point includes the first cell, and the first information includes measurement information and/or frequency information of the neighboring cell (first cell) of the first frequency point when the first frequency point is an inter-frequency point of the terminal device, wherein the measurement information of the first cell includes one or more of the following: timing information, measurement value, synchronization signal block index SSB index, automatic gain control (automatic gain control, AGC) gear information. The terminal device multiplexes the first information into the same-frequency point neighboring cell information list of the first frequency point after switching, that is, the terminal device multiplexes the measurement information of the first cell from the inter-frequency neighboring cell information list of the first frequency point to the same-frequency neighboring cell information list of the first frequency point.

S203: The communication device multiplexes the second information into the inter-frequency point neighboring cell information list of the second frequency point.

Among them, the second information is the neighboring area information of the second frequency point when the same frequency point is the second frequency point before the terminal device switches to the same frequency point, or it can be called the same-frequency neighboring area information of the second frequency point.

Specifically, the co-frequency point of the terminal device is switched from the second frequency point to the first frequency point, and the second frequency point is changed from the co-frequency point of the terminal device to the hetero-frequency point of the terminal device. The terminal device then multiplexes the second information into the hetero-frequency point neighboring area information list of the second frequency point after the co-frequency point is switched.

It should be understood that the second information is multiplexed into the inter-frequency point neighbor information list of the second frequency point, or it can be said that the second information is inherited to the inter-frequency point neighbor information list of the second frequency point, or it can be said that the second information is updated to the inter-frequency point neighbor information list of the second frequency point. That is, the terminal device stores the second information in the inter-frequency point neighbor information list of the second frequency point after switching, and can be directly used by the terminal device.

In one possible implementation, the neighboring cell of the second frequency point includes the second cell, and the second information includes measurement information and/or frequency information of the neighboring cell (second cell) of the second frequency point when the second frequency point is an inter-frequency point of the terminal device, wherein the measurement information of the second cell includes one or more of the following: timing information, measurement value, synchronization signal block index SSB index, AGC gear information. The terminal device multiplexes the second information into the inter-frequency point neighboring area information list of the second frequency point after switching, that is, the terminal device multiplexes the measurement information of the second cell from the same-frequency neighboring area information list of the second frequency point to the inter-frequency neighboring area information list of the second frequency point.

In another possible implementation, the neighboring cells of the first frequency point include the first cell, the neighboring cells of the second frequency point include the second cell, and the first cell and the second cell need to meet a first condition. The first condition includes:

In the first time period, the terminal device completes cell measurement reporting for the first cell and the second cell or the terminal device completes identification of the first cell and the second cell,

and,

The signal strength of the first cell and the second cell relative to the terminal device is greater than or equal to a first threshold.

It should be understood that the signal strength of the first cell and the second cell before and after the same frequency point switching of the terminal device is greater than or equal to the first threshold. The first cell can be one cell or multiple different cells, and the second cell can be one cell or multiple different cells, which is not limited in this application. Among them, the first cell and the second cell can also be the same cell or different cells, which is not specifically limited in this application.

The size of the first threshold may be determined by the terminal device itself, or may be predefined by the system or determined through certain indication information, and this application does not make any specific limitation on this.

It should be understood that the first time period may be a time period before the same frequency point of the terminal device switches from the second frequency point to the first frequency point, and this application does not impose any specific restrictions on the length of the first time period.

As an example, before the co-frequency point of the terminal device changes, frequency point #0 is the co-frequency point of the terminal device, and the adjacent frequency point #0 The cells include cell #0, frequency point #1 is a different frequency point of the terminal device, the adjacent cells of frequency point #1 include cell #1, and within a certain continuous time period before the same frequency point of the terminal device changes, the terminal device completes the cell measurement reporting of cell #0 and cell #1, or the terminal device identifies cell #0 and cell #1. At the same time, the signal strength of cell #1 and cell #0 relative to the terminal device before the same frequency point of the terminal device changes and the signal strength relative to the terminal device after the same frequency point of the terminal device changes are both greater than or equal to a certain threshold (e.g., a first threshold).

In another possible implementation method, the first condition also includes: the first measurement configuration parameter is the same as the second measurement configuration parameter, the first measurement configuration parameter is the measurement configuration parameter of the first frequency point and the second frequency point before the same frequency point of the terminal device is switched, and the second measurement configuration parameter is the measurement configuration parameter of the first frequency point and the second frequency point after the same frequency point of the terminal device is switched from the second frequency point to the first frequency point.

Optionally, the first measurement configuration parameter and the second measurement configuration parameter include one or more of the following: frequency information, cell identification information, and synchronization signal block SSB information.

It should be understood that before and after the same frequency point of the terminal device changes, the measurement configuration parameters of the same frequency point remain unchanged, and the adjacent cells of the frequency point can be considered as known neighboring cells of the terminal device.

As an example, before the co-frequency point of the terminal device is switched, frequency point #A is the co-frequency point of the terminal device, and frequency point #B is the hetero-frequency point of the terminal device. The co-frequency point of the terminal device is switched from frequency point #A to frequency point #B. After the switching, frequency point #B is the co-frequency point of the terminal device, and frequency point #A is the hetero-frequency point of the terminal device. Before and after the switching of the terminal device, the measurement configuration parameters of frequency point #A are the same as the measurement configuration parameters of frequency point #A after the switching; before and after the switching of the terminal device, the measurement configuration parameters of frequency point #B are the same as the measurement configuration parameters of frequency point #B after the switching, that is, the neighboring area corresponding to frequency point #A and the neighboring area corresponding to frequency point #B are known neighboring areas of the terminal device.

It should be understood that before the co-frequency point of the terminal device is switched, the second frequency point may include the co-frequency point of the terminal device and the hetero-frequency point of the terminal device. When the co-frequency point of the terminal device is switched to the first frequency point, the co-frequency point in the second frequency point is switched to the hetero-frequency point of the terminal device. After the switch, in the measurement configuration information obtained by the terminal device, the hetero-frequency point in the second frequency point may still be the hetero-frequency point of the terminal device. In the process of information multiplexing, the co-frequency point neighboring area information of the terminal device in the second frequency point before the switch is multiplexed into the hetero-frequency point neighboring area information list of the frequency point after the switch, and the hetero-frequency point neighboring area information of the terminal device in the second frequency point before the switch is multiplexed into the hetero-frequency point neighboring area information list of the frequency point after the switch.

As an example, when the first frequency point includes frequency point #0, and the second frequency point includes frequency point #1 and frequency point #2, wherein frequency point #0 is the different frequency point before the terminal device switches to the same frequency point, frequency point #1 is the same frequency point before the terminal device switches to the same frequency point, and frequency point #2 is the different frequency point before the terminal device switches to the same frequency point. The same frequency point of the terminal device is switched from the second frequency point to the first frequency point, which can be understood as the same frequency point of the terminal device is switched from frequency point #1 to frequency point #0, and after the switch, frequency point #2 is still the different frequency point of the terminal device. The terminal device can multiplex the neighboring area information when frequency point #1 is the different frequency point of the terminal device into the neighboring area information list when frequency point #1 is the same frequency point of the terminal device; the terminal device can multiplex the neighboring area information when frequency point #0 is the different frequency point into the neighboring area information list when frequency point #0 is the same frequency point of the terminal device. Among them, after the co-frequency point of the terminal device is switched, frequency #0 is the co-frequency point of the terminal device. When the measurement configuration information of the terminal device includes frequency #2, the terminal device can continue to multiplex the heterofrequency neighboring area information of frequency #2 before the co-frequency point switching into the heterofrequency neighboring area information of frequency #2 after the switching.

FIG. 3 is a specific example based on the method shown in FIG. 2 .

3 is a schematic diagram showing that the activated BWP of the terminal device is switched, resulting in a change in the co-frequency point of the terminal device.

As shown in Figure 3, the frequency point corresponding to the source activated BWP of the terminal device is SSB_Freq_1, that is, Freq_1 is the original co-frequency point of the terminal device, and Freq_2 is the original hetero-frequency point of the terminal device. Among them, the service cell of the Freq_1 co-frequency point cell service information is the S cell, and the neighboring cell information included in the adjacent cell (referred to as the neighboring cell in this application) information list includes neighboring cell 1: n1_1, neighboring cell 1: n1_2, etc. The service cell of the Freq_2 hetero-frequency point cell service information is the S cell, and the neighboring cell information included in the neighboring cell information list includes neighboring cell 1: n2_1, neighboring cell 2: n2_2, etc. The activated BWP of the terminal device is switched, resulting in a change in the co-frequency point of the terminal device. After the co-frequency point changes, Freq_2 becomes the current co-frequency point of the terminal device, and Freq_1 is the current hetero-frequency point of the terminal device.

The terminal device multiplexes the service cell of the Freq_1 same-frequency cell service information as the S cell, and the neighboring cell information included in the neighboring cell information list includes neighboring cell 1: n1_1, neighboring cell 1: n1_2, etc. into the updated Freq_1 different-frequency neighboring cell information list, then the Freq_1 different-frequency cell service information serves the S cell, and the different-frequency neighboring cell information includes neighboring cell 1: n1_1, neighboring cell 1: n1_2, etc. The terminal device multiplexes the service cell of the Freq_2 different-frequency cell service information as the S cell, and the neighboring cell information included in the neighboring cell information list includes neighboring cell 1: n2_1, neighboring cell 2: n2_2, etc. into the updated Freq_2 same-frequency neighboring cell information list, then the Freq_2 same-frequency cell service information serves the S cell, and the same-frequency neighboring cell information includes neighboring cell 1: n1_1, neighboring cell 1: n1_2, etc.

It should be understood that the neighboring area of Freq_1 and the neighboring area of Freq_2 both meet the first condition shown in FIG. 2 . Please refer to the specific introduction in FIG. 2 above for details, which will not be repeated here.

According to the method shown in FIG. 2 above, in the scenario where the same frequency point of the terminal device is switched, the terminal device directly switches the first frequency point to The inter-frequency point neighbor information is multiplexed into the co-frequency point neighbor information list of the first frequency point, and the terminal device directly multiplexes the co-frequency point neighbor information of the second frequency point into the inter-frequency point neighbor information list of the second frequency point. After the co-frequency point of the terminal device changes, the terminal device no longer needs to search and obtain the SSB index, thereby avoiding the time for the terminal device to search and obtain the SSB index, reducing the delay in reporting the measurement results of the terminal device, and improving the mobility performance of the terminal device.

Next, the method shown in FIG. 2 will be described in detail in combination with three different scenarios.

It should be noted that the three different scenarios are intended to facilitate those skilled in the art to better understand the method provided in the embodiments of the present application, and do not have any limiting effect on the present application. The method provided in the embodiments of the present application can also be applied to other scenarios, and in order to avoid redundancy, the present application does not list them one by one.

Scene 1

Assuming that the terminal device is a RedCap UE, the activated BWP of the RedCap UE switches, and the co-frequency point of the RedCap UE changes due to the change of the SSB frequency point in the co-frequency neighboring cell.

In the relevant protocols of 3Gpp, RedCap UE supports the configuration of non-cell defining SSB (NCD-SSB). In the connected scenario, the network equipment can configure multiple BWPs for the UE (no more than 4). Among them, each BWP has at most one SSB, where the SSB can be a cell defining SSB (CD-SSB) or NCD-SSB, that is, there are multiple SSBs in the cell bandwidth. Among them, when the SSB in the activated BWP is NCD-SSB, RedCap UE uses this SSB for timing synchronization and RRM measurement and other functions. For the parameter configuration of NCD-SSB and CD-SSB, only the center frequency, SSB period and time domain position offset can be configured separately, and other parameters are the same as CD-SSB.

For RedCap UE, the newly added NCD-SSB parameters in BWP and serving cell measurement objects (serving cell measurement objects, serving cell MO) can be further configured through signaling messages.

It should be understood that in the scenario where ServingCellMO is configured in BWP, the RRM measurement uses the frequency of the SSB in the activated BWP as the reference frequency for the same-frequency cell measurement. Due to the BWP switching, the reference SSB frequency of the serving cell changes after the activated BWP changes, resulting in a change in the definition of the same-frequency neighboring cell. Since the center frequency of the same-frequency SSB changes, the timing offset configuration parameters of NCD-SSB and CD-SSB for the serving cell can determine the timing position of the target SSB after the BWP switching. However, due to the change in the frequency of the neighboring cell, after the new same-frequency point and the original same-frequency point are measured, the neighboring cell measurement of the terminal device needs to re-search and measure and obtain the SSB index, that is, there is a certain delay, resulting in poor mobility of the terminal device.

In the scenario where the activated BWP of the RedCap UE is switched, as an example, if all BWPs of the RedCap UE are configured with corresponding SSB measurement MOs, the following steps may be included:

Step 1: For all BWPs of RedCap UE, the corresponding SSB measurement MO is configured, and the frequency point is recorded as f_i, where i is the corresponding MO. The maximum value of BWP is 4, and the maximum value of i is 4;

Step 2: RedCap UE measures f_i and obtains the cell measurement information of the f_i frequency point.

Among them, the cell measurement information may include one or more of the following: timing information, measurement value, SSB index and other information, and AGC gear information.

Step 3: The activated BWP of RedCap UE is the jth BWP, and the frequency point is recorded as f_j, that is, the co-frequency point corresponding to RedCap UE is f_j, and the neighboring area corresponding to the frequency point f_ can be called the co-frequency neighboring area.

Step 4: The activated BWP of the RedCap UE is switched, such as the activated BWP is switched from the jth BWP to the kth BWP. When the activated BWP is switched to the kth, the corresponding frequency point f_k is updated to the same frequency point as the RedCap UE, and the frequency point f_j is updated to the different frequency point of the RedCap UE. The RedCap UE further determines whether the cells corresponding to the frequency points f_k and f_j meet the first condition (the first condition can also be called the condition of the known neighboring cells).

In one possible implementation, when the cells corresponding to frequency points f_k and frequency point f_j meet the first condition, step 5A is executed: the RedCap UE multiplexes the neighboring cell information of the f_k different-frequency point before activating the BWP switching into the neighboring cell list of the current f_k same-frequency point; the RedCap UE multiplexes the neighboring cell information of the f_j same-frequency point before activating the BWP switching into the neighboring cell list of the current f_j different-frequency point.

In another possible implementation, when the cells corresponding to frequency f_k and frequency f_j do not meet the first condition, step 5B is executed: RedCap UE re-searches the cell and obtains the SSB index and updates the measurement results for the same frequency point f_k and the different frequency point f_j.

It should be understood that the detailed process in step 5B may be referred to in the prior art and will not be described in detail here.

According to the introduction of steps 1 to 5 above, when the activated BWP is switched, the frequency point corresponding to the BWP is updated from the different frequency point to the same frequency point, or from the same frequency point to the different frequency point relative to the RedCap UE. The RedCap UE reuses (or inherits) the neighboring cell measurement results of the frequency point, without re-acquiring the cell measurement information, thereby avoiding the time of searching and SSB index acquisition, and speeding up the reporting of the overall measurement results.

In the scenario where the activated BWP of the RedCap UE is switched, as an example, if some BWPs of the RedCap UE are configured with corresponding SSB measurement MOs, the following steps may be included:

Step 1: For some BWPs of RedCap UE, the corresponding SSB measurement MO is configured. The frequency point is recorded as f_i, and i is the corresponding MO. The maximum value of BWP is 4, and the maximum value of i is 4;

Among them, the cell measurement information may include one or more of the following: timing information, measurement value, SSB index, AGC gear information and other information.

Step 3: The activated BWP of RedCap UE is the jth BWP, and the corresponding frequency point is recorded as f_j, that is, the co-frequency point corresponding to RedCap UE is f_j, and the neighboring cell corresponding to frequency point f_j can be called the co-frequency neighboring cell.

Step 4: The activated BWP of RedCap UE is switched, for example, the jth BWP of the activated BWP switches to the kth BWP.

In a possible implementation, when the activated BWP is switched to the kth BWP, and the corresponding kth BWP is configured with the corresponding SSB measurement MO, the frequency point f_k corresponding to the kth BWP is updated to the same frequency point of the RedCap UE, and the frequency point f_j is updated to the different frequency point of the RedCap UE. The RedCap UE further determines whether the cells corresponding to the frequency points f_k and f_j meet the first condition (or the condition of the known neighboring cells). The specific steps are similar to step 4 in the case where all BWPs of the RedCap UE are configured with the corresponding SSB measurement MO, and will not be repeated here.

In another possible implementation, when the activated BWP is switched to the kth BWP, and the corresponding kth BWP is not configured with the corresponding SSB measurement MO, the RedCap UE needs to re-search the neighboring cells and obtain the SSB index. According to the relevant protocol, the RedCap UE updates the CD-SSB frequency point to the same frequency point as the RedCap UE, and updates f_j to the different frequency point of the RedCap UE. The RedCap UE further determines whether the cell corresponding to the CD-SSB frequency point and the frequency point f_j meets the first condition (or the condition of the known neighboring cell).

In one possible implementation method, when the cells corresponding to the frequency points CD-SSB and the frequency point f_j meet the first condition, step 5A is executed: the RedCap UE multiplexes the neighboring cell information of the CD-SSB different-frequency point before activating the BWP switching into the neighboring cell list of the current CD-SSB same-frequency point; the RedCap UE multiplexes the neighboring cell information of the f_j same-frequency point before activating the BWP switching into the neighboring cell list of the current f_j different-frequency point.

In another possible implementation method, when the cells corresponding to the frequency points CD-SSB and the frequency point f_j do not meet the first condition, step 5B is executed: the RedCap UE re-searches the cells and obtains the SSB index and updates the measurement results for the same frequency point CD-SSB and the different frequency point f_j.

It should be understood that the detailed process in step 5B can be found in the prior art and will not be described again here.

According to the introduction of steps 1 to 5 above, when the activated BWP is switched and the activated BWP after switching is not configured with the corresponding SSB measurement MO, RedCap UE updates the relevant protocols to determine that the CD-SSB frequency point is updated to the same frequency point of RedCap UE, and the f_j same frequency point is updated to the different frequency point of RedCap UE. RedCap UE reuses (or inherits) the neighboring area measurement results of the frequency point, and the terminal device does not need to re-search and obtain the SSB index, which speeds up the reporting of the terminal device measurement results.

Scene 2

Assuming that the terminal device is a Normal UE, the source service cell of the terminal device is switched to the target service cell due to the movement of the terminal device, and the co-frequency point of the terminal device is switched. That is, the co-frequency point of the source service cell of the terminal device may become the hetero-frequency point of the target service cell after the terminal device is switched.

As an example, for example, cell #0 is the source service cell of the terminal device, and cell #1 is the target service cell after the terminal device is switched.

Before the cell is switched, the frequency point in cell #0 (e.g., frequency point #0) is the same frequency point of the terminal device, and the frequency point in cell #1 (frequency point #1) is the different frequency point of the terminal device. As the location of the terminal device moves, the service cell of the terminal device is switched, which further causes the change of the same frequency point of the terminal device.

After the cell switching, the frequency point #0 in the cell #0 is updated to the different frequency point of the terminal device, and the frequency point #1 in the cell #1 is updated to the same frequency point of the terminal device.

The terminal device measures the frequency points configured for the source service cell and the frequency points configured for the target service cell and determines whether the first condition is met.

It should be understood that the first condition includes:

1) Within a continuous period (e.g., a first period) before the cell switching of the terminal device occurs, the neighboring cells of the source serving cell configured with the frequency point and the neighboring cells of the target serving cell configured with the frequency point have completed measurement reporting, or the terminal device has completed identification of the neighboring cells of the source serving cell configured with the frequency point and the neighboring cells of the target serving cell configured with the frequency point;

2) Before and after the cell switching, the signal strengths of the neighboring cells of the source serving cell and the neighboring cells of the target serving cell are both maintained above a level that can be recognized by the terminal device, that is, the signal strengths of the neighboring cells relative to the terminal device are both greater than or equal to a certain threshold (e.g., a first threshold);

3) Before and after cell switching, the measurement configuration parameters of the same frequency point are the same.

Among them, the measurement configuration parameters may include one or more of the following: frequency information, cell identification information, and synchronization signal block SSB information.

It should be understood that due to the movement of the terminal device, the service cell of the terminal device is switched, resulting in the change of the co-frequency point of the terminal device. The terminal device directly multiplexes the neighboring area information of the source co-frequency point into the neighboring area information of the changed hetero-frequency point. The terminal device directly multiplexes the neighboring area information of the source hetero-frequency point into the neighboring area information of the changed co-frequency point for direct use. The neighboring area information of the source co-frequency point and the neighboring area information of the source hetero-frequency point must satisfy 1), 2) and 3) of the above-mentioned first condition before and after the cell switching.

In one possible implementation, when the terminal device determines that all neighboring areas of the frequency points configured for the source service cell and all neighboring areas of the frequency points configured for the target service cell meet the first condition, the first terminal device multiplexes all neighboring area information of different frequency points of the source service cell before switching into the list of neighboring area information of the same frequency point of the target service cell after switching; the first terminal device multiplexes all neighboring area information of the same frequency point of the source service cell before switching into the list of neighboring area information of different frequency points of the target service cell after switching.

In another possible implementation, when the terminal device determines that some neighboring areas of the frequency points configured by the source service cell and some neighboring areas of the frequency points configured by the target service cell meet the first condition, and there are some neighboring areas that do not meet the first condition, the first terminal device multiplexes the neighboring area information of the different frequency points of the source service cell that meets the first condition before switching into the list of neighboring area information of the same frequency points of the target service cell after switching; the first terminal device multiplexes the neighboring area information of the same frequency points of the source service cell that meets the first condition before switching into the list of neighboring area information of the different frequency points of the target service cell after switching.

It should be understood that when the terminal device determines that the neighboring cells of the frequency points configured by the source service cell and the neighboring cells of the frequency points configured by the target service cell do not meet the first condition, the terminal device needs to re-search the cell and obtain the SSB index and update the measurement results for the same frequency points and different frequency points after the cell switching. The specific detailed process may refer to the prior art and will not be repeated here.

It should also be understood that in the scenario of cell switching, the co-frequency point, hetero-frequency point or hetero-system frequency point of the source service cell of the terminal device may become the co-frequency point, hetero-frequency point or hetero-system frequency point of the target service cell after the cell switching of the terminal device. In this case, the measurement method provided in the embodiment of the present application is also applicable, that is, the terminal device can reuse the neighboring area information of the frequency point before switching into the neighboring area list of the frequency point after switching. The terminal device can reuse the neighboring area information of the relevant frequency points, thereby avoiding the time for the terminal device to re-search and obtain the SSB index, and reducing the measurement delay.

According to the specific example of scenario 2 above, the service cell of the terminal device switches, resulting in a corresponding change in the co-frequency point of the terminal device. The terminal device can reuse the neighboring cell information of the co-frequency point before the switch to the neighboring cell information of the heterofrequency point after the switch, and reuse the neighboring cell information of the heterofrequency point before the switch to the neighboring cell information of the co-frequency point after the switch, thereby avoiding the time for the terminal device to search and obtain the SSB index, thereby improving the switching performance of the terminal device.

FIG4 is a schematic diagram of another measurement method provided in an embodiment of the present application. As shown in FIG4 , the method includes:

S401, the terminal device adds frequency point #1 as a co-frequency point of the terminal device, and the co-frequency point includes frequency point #2.

Specifically, before the terminal device adds frequency #1 as the co-frequency point, the co-frequency point of the terminal device is frequency #2, and frequency #1 is the hetero-frequency point of the terminal device. The terminal device adds frequency #1 as its own co-frequency point, that is, after adding the co-frequency point, the co-frequency points of the terminal device include frequency #1 and frequency #2.

As an example, when carrier aggregation CA occurs in a terminal device, a carrier unit CC frequency is added, and a heterofrequency point (for example, frequency #1) of the Pcell/PScell cell becomes the co-frequency point (service frequency) of the target cell, that is, the terminal device adds the source heterofrequency point #1 as the co-frequency point.

S402, the terminal device multiplexes the first information into the same-frequency neighboring area information list of frequency point #1.

Specifically, after the terminal device determines to add frequency point #1 to the same frequency point of the terminal device, the terminal device multiplexes the first information into the same frequency neighboring area information list of frequency point #1. The first information is the different frequency neighboring area information of frequency point #1.

It should be understood that before the terminal device adds the same frequency point, the frequency point #1 is the different frequency point of the terminal device, and the neighboring area information of the frequency point #1 can be called the different frequency neighboring area information of the frequency point #1. When the frequency point #1 is the same frequency point of the terminal device, the terminal device can multiplex the different frequency neighboring area information of the frequency point #1 into the same frequency neighboring area information of the frequency point #1.

In a possible implementation manner, the neighboring cell of frequency point #1 includes a first cell, and the first cell satisfies a first condition, where the first condition includes:

1) Within the first time period, the terminal device completes cell measurement reporting for the first cell or the terminal device completes cell identification for the first cell;

2) The signal strength of the first cell relative to the terminal device is greater than or equal to a first threshold.

It should be understood that when the first cell meets the first condition, the terminal device multiplexes the first information into the same-frequency neighboring cell information list of frequency point #1, wherein the first information includes the measurement information of the first cell, and the measurement information includes timing information, measurement value, synchronization signal One or more of the block index SSB index, AGC gear information, etc. Among them, the first cell can be one or more neighboring cells of frequency point #1, which is not limited in this application.

It should also be understood that the size of the first threshold may be determined by the terminal device itself, or may be predefined by the system or determined through certain indication information, and this application does not make any specific limitation on this.

It should also be understood that the first time period may be a continuous time period before the terminal device adds frequency point #1 as the same frequency point of the terminal device.

As an example, assume that the neighboring area corresponding to frequency point #1 is cell #1. In the case where frequency point #1 is updated from the heterofrequency point of the terminal device to the co-frequency point of the terminal device, the terminal device completes the cell measurement report for cell #1 or the terminal device completes the cell identification for cell #1 in a certain continuous time period before frequency point #1 is updated from the heterofrequency point of the terminal device to the co-frequency point of the terminal device, and the signal strength of cell #1 relative to the terminal device before and after frequency point #1 is updated from the heterofrequency point of the terminal device to the co-frequency point of the terminal device is greater than or equal to a certain threshold (for example, the first threshold), that is, cell #1 meets the first condition, and cell #1 is a known neighboring area of the terminal device. In the case where frequency point #1 is updated from the heterofrequency point of the terminal device to the co-frequency point of the terminal device, the terminal device can directly multiplex the information of cell #1 into the co-frequency point of the terminal device, including the co-frequency neighboring area information list of frequency point #1.

According to the method shown in FIG4 above, in the scenario where the same-frequency point of the terminal device is added (for example, the service frequency point is added under CA), the terminal device directly multiplexes the inter-frequency point neighboring cell information of frequency point #1 into the same-frequency point neighboring cell information list of frequency point #1. The terminal device no longer needs to search for the neighboring cells of frequency point #1 and obtain the SSB index, thereby avoiding the time for the terminal device to search and obtain the SSB index, reducing the delay in reporting the measurement results of the terminal device, and improving the mobility performance of the terminal device.
