In addition, the character "/" in this document generally indicates that the related objects are an "or" relationship.

In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the following describes the technical solutions related to the embodiments of the present application.

With people's pursuit of speed, delay, high-speed mobility, energy efficiency, and the diversity and complexity of services in future life, the ^3rd Generation Partnership Project (3GPP) international standards organization began to develop 5G . The main application scenarios of 5G are: Enhanced Mobile Broadband (eMBB), Ultra Reliable Low Latency Communication (URLLC), and Massive Machine Type Communication (mMTC).

On the one hand, eMBB still aims at users' access to multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoors, urban areas, rural areas, etc., its capabilities and requirements are also quite different, so it cannot be generalized and must be analyzed in detail in combination with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, telemedicine operations (surgery), traffic safety assurance, etc. Typical features of mMTC include: high connection density, small data volume, latency-insensitive services, low cost and long service life of the module.

In the early deployment of NR, complete NR coverage is difficult to obtain, so typical network coverage is wide-area LTE coverage and NR island coverage mode. And a lot of LTE is deployed in sub-6GHz, and there is very little sub-6GHz spectrum available for 5G. Therefore, NR must study the spectrum application above 6GHz, while the high frequency band has limited coverage and fast signal fading. At the same time, in order to protect the early investment of mobile operators in LTE, a working mode of tight interworking between LTE and NR is proposed.

In order to realize 5G network deployment and commercial application as soon as possible, 3GPP first completed the first 5G version, namely LTE-NR Dual Connectivity (EN-DC). In EN-DC, the LTE base station acts as a master node (Master Node, MN), and the NR base station acts as a secondary node (Secondary Node, SN), and is connected to the Evolved Packet Core network (EPC). Later in R15, other Dual Connectivity (DC) modes will be supported, namely NR-LTE Dual Connectivity (NE-DC), 5GC-EN-DC, NR DC. In NE-DC, the NR base station acts as the MN, and the LTE base station acts as the SN, connecting to the 5G core network (5GC). In 5GC-EN-DC, the LTE base station is used as MN, and the NR base station is used as SN, which is connected to 5GC. In NR DC, the NR base station acts as the MN, and the NR base station acts as the SN, which is connected to the 5GC.

The technical solutions of the embodiments of the present application can be applied not only to a dual-connectivity architecture (such as an MR-DC architecture), but also to a multiple connectivity (Multiple Connectivity, MC) architecture. Typically, the MC architecture may be an MR-MC architecture.

NR can also be deployed independently. NR will be deployed on high frequencies in the future. In order to improve coverage, in 5G, the mechanism of beam sweeping is introduced to meet the coverage requirements (replace space for coverage, and time for space), as shown in Figure 2. After the introduction of beam sweeping, a synchronization signal needs to be sent in each beam direction. The synchronization signal of 5G is given in the form of a synchronization signal block (SS/PBCH Block, SSB), including the primary synchronization signal (Primary Synchronisation Signal, PSS), A secondary synchronization signal (Secondary Synchronisation Signal, SSS), and a physical broadcast channel (Physical Broadcast Channel, PBCH), as shown in Figure 3. The 5G synchronization signal appears periodically in the time domain in the form of a synchronization signal burst set (SS burst set). As shown in Figure 4, the period of the SS burst set can also be called the period of the SSB.

The actual number of beams (beams) transmitted in each cell is determined by the configuration on the network side, but the frequency point where the cell is located determines the maximum number of beams that can be configured, as shown in Table 1 below.

频率范围Frequency Range	L(最多的beam个数)L (maximum number of beams)
(2.4)GHz以下(2.4) GHz or less	44
3(2.4)GHz—6GHz3(2.4)GHz—6GHz	88
6GHz—52.6GHz6GHz—52.6GHz	6464

Table 1

In radio resource management (Radio Resource Management, RRM) measurement, the measured reference signal can be SSB, that is, the SSS signal in the SSB or the demodulation reference signal (Demodulation Reference Signal, DMRS) signal of the PBCH is measured to obtain beam measurement results and Cell measurement results. In addition, a terminal device in a radio resource control (Radio Resource Control, RRC) connection state can also configure a channel status indicator reference signal (Channel Status Indicator Reference Signal, CSI-RS) as a reference signal for cell measurement.

For SSB-based measurements, the actual transmission position of the SSB in each cell may be different, and the period of the SS burst set may also be different. Therefore, in order to allow the terminal device to save energy during the measurement process, the network side configures the terminal device with the SSB measurement timing configuration (SS/PBCH block measurement timing configuration, SMTC). measurements, as shown in Figure 5.

Since the location of the SSB actually transmitted by each cell may be different, in order for the terminal device to find the location of the actually transmitted SSB as soon as possible, the network side will also configure the terminal device with the actual SSB transmission location measured by the terminal device, such as all The union of the actual transmission positions of the SSBs of the measurement cells is shown in Table 2 below. As an example, at 3-6 GHz, the length of the bitmap is 8 bits. Assuming that the bitmap of 8 bits length is 10100110, then the terminal device only needs to set the SSB indices in the candidate positions of the 8 SSBs as 0, 2, 5, 6 SSB to do the measurement.

Table 2

For the energy saving of terminal equipment, the concept of SCG deactivation is introduced. After the SCG is deactivated, the downlink timing relationship between the terminal equipment and the PSCell may not be maintained. The terminal equipment needs to measure the measurement of the SN configuration. For the measurement configuration of the SN configuration, the SMTC is generally configured for the measurement object. purpose of electricity. In the measurement configuration of the SN configuration, the time domain position of the SMTC to be measured is determined based on the downlink timing of the PSCell.

However, after the SCG is deactivated, if the terminal equipment loses the downlink timing of the PSCell (that is, the downlink timing relationship between the terminal equipment and the terminal equipment cannot be maintained), the terminal equipment cannot determine the position of the SMTC in the time domain. How the terminal equipment performs the measurement of the SN configuration needs to be clarified. To this end, the following technical solutions of the embodiments of the present application are proposed.

FIG. 6 is a schematic flowchart of a measurement method provided by an embodiment of the present application. As shown in FIG. 6 , the measurement method includes the following steps:

Step 601: In the case where the terminal device loses the downlink timing of the PSCell, the terminal device determines the measurement mode for the first measurement configuration; wherein the first measurement configuration is the measurement configuration configured by the SN, and the PSCell is the SN The primary cell in the corresponding SCG.

In some optional embodiments, the technical solutions of the embodiments of the present application may be applied to a dual-connection architecture. The dual-connectivity architecture includes one MN and one SN, where the cell group corresponding to the MN is called MCG, the MCG includes a primary cell (PCell) and one or more secondary cells (SCell), and the cell group corresponding to the SN is called SCG, SCG It includes one PSCell, and optionally, one or more SCells. The MN can configure the measurement configuration for the terminal device, specifically, the PCell configures the measurement configuration for the terminal device. The SN may also configure a measurement configuration for the terminal device, specifically, the PSCell configures the measurement configuration for the terminal device. The measurement configurations configured for the terminal equipment by the MN and SN are independent of each other.

In some optional embodiments, the technical solutions of the embodiments of the present application may be applied to a multi-connection architecture. The difference from the dual-connection architecture is that the multi-connection architecture includes one MN and multiple SNs, and the MN and SN may refer to the foregoing description of the dual-connection architecture.

In this embodiment of the present application, the first measurement configuration is the measurement configuration configured by the SN, and the SN may send the first measurement configuration to the terminal device through an RRC connection reconfiguration message.

In some optional embodiments, the first measurement configuration includes: a measurement object list, a measurement report list, and a measurement list. The measurement list includes at least one measurement id, and each measurement id is associated with a measurement object and a measurement report. For a measurement object, an SMTC configuration is configured for it, and the time domain position of the SMTC configuration is determined based on the downlink timing of the PSCell, that is, the time domain position of the SMTC can be determined based on the downlink timing of the PSCell.

It should be noted that the "downlink timing" in the embodiments of the present application may also be referred to as "reference timing".

In the embodiment of the present application, the SCG on the SN side may be in an activated state or a deactivated state. After the SGC is deactivated, all cells in the SGC are in a deactivated state, so as to achieve the purpose of energy saving of the terminal equipment. After the SCG is deactivated, the terminal device will lose the downlink timing of the PSCell. Specifically, the terminal device receives second indication information, where the second indication information is used to instruct the deactivation of the SCG, wherein after the deactivation of the SCG, the terminal device loses the downlink timing of the PSCell.

Here, the downlink timing of the PSCell is used by the terminal device to determine the time domain position of the SMTC, and then measure within the SMTC window according to the time domain position of the SMTC. If the terminal equipment loses the downlink timing of the PSCell, the measurement method for the measurement configuration of the SN configuration is one of the following.

(1) The terminal device determines not to perform measurement for the first measurement configuration.

Specifically, after the terminal device loses the downlink timing of the PSCell, the terminal device does not perform the measurement for using the PSCell as the reference timing, that is, does not perform the measurement of the first measurement configuration (that is, the measurement of the SN configuration).

(2) The first measurement configuration at least includes configuration information of the first measurement object; in the second measurement configuration, there is a second measurement object that is associated with the first measurement object, and the second measurement configuration is the main The measurement configuration configured by the node MN; the terminal device determines that the measurement mode for the first measurement object is the first measurement mode, where the first measurement mode includes: the terminal device corresponds to the second measurement object based on The SMTC configuration is performed, and the measurement for the first measurement object is performed.

In an optional manner, the association relationship refers to: the synchronization signal block SSB frequency points and/or subcarrier intervals of the measurement object are the same.

Here, the SMTC configuration corresponding to the second measurement object is used to determine the first SMTC, and the time domain position of the first SMTC is determined based on the downlink timing of the PCell, where the PCell is the primary cell group MCG corresponding to the MN. The primary cell, the first SMTC is the SMTC used by the first measurement object to perform measurement.

Specifically, when the terminal device loses the downlink timing of the PSCell, the terminal device uses the measurement configuration (ie, the second measurement configuration) configured by the MN for the first measurement object, which is the same as the SSB frequency of the first measurement object and has the same subcarrier. The SMTC corresponding to the second measurement object with the same interval is used as the SMTC used for measuring the first measurement object. Here, the second measurement object in the measurement configuration configured by the MN is, for example, measObjectNR.

(3) The first measurement configuration includes at least configuration information of the first measurement object; the terminal device determines that the measurement mode for the first measurement object is the second measurement mode, where the second measurement mode includes: The terminal device performs measurement on the first measurement object based on the first SSB period.

In some optional embodiments, the first SSB period is 5ms or 10ms.

Specifically, after the terminal device loses the downlink timing of the PSCell, the terminal device assumes that the SSB cycle is 5ms, and performs measurement on the first measurement object according to the SSB cycle of 5ms.

It should be noted that the SSB period can also be referred to as the period of the SS burst set.

In an optional manner, the method further includes: receiving, by the terminal device, first indication information, where the first indication information is used to indicate that the measurement method for the first measurement object is the first measurement in the above solution or the second measurement method in the above solution.

The above-mentioned technical solutions of the embodiments of the present application can be embodied by the contents shown in Table 3 below:

table 3

(4) The first measurement configuration at least includes configuration information of a third measurement object; there is no measurement object associated with the third measurement object in the second measurement configuration, and the second measurement configuration is an MN configuration The measurement configuration; the terminal device determines that the measurement mode for the third measurement object is relaxation measurement.

Here, when the SCG is deactivated, the measurement of the SN configuration can be relaxed, so as to achieve the purpose of power saving of the terminal equipment. Specifically, if the SSB frequency and/or subcarrier spacing of a certain measurement object configured by the SN is the same as the SSB frequency and/or subcarrier spacing of a certain measurement object configured by the MN, the measurement object configured by the SN cannot be Relax measurement. If the SSB frequency and/or subcarrier spacing of a certain measurement object configured by the SN is different from the SSB frequency and/or subcarrier spacing of all measurement objects configured by the MN, the measurement object configured by the SN can perform relaxed measurement.

In this embodiment of the present application, the relaxed measurement may be implemented by, but not limited to, the following: extending the measurement period of the SSB.
