Description

Method and device for sending synchronization information block

Technical Field

The present disclosure relates to the field of computer communications technologies, and in particular, to a method and an apparatus for sending a synchronization block.

Background

The 5G, NR (New Radio) network related standardization is under way in 3GPP (3rd Generation partnership project). One of the key technologies of the 5G network communication system is as follows: beamforming (beamforming) techniques. When broadcasting the downlink synchronous signals and necessary system information, a beam scanning method is adopted in a 5G high-frequency system, and coverage cells are rapidly scanned by concentrated power.

Because the 5G network communication system is required to serve both ultra-low delay users and machine internet of things users that are extremely insensitive to delay, in some application scenarios, if a region far from the base station is distributed with only user equipment that is insensitive to delay and requires a small data rate. If the same synchronization information block transmission mechanism is adopted to satisfy the coverage of all the user equipment according to the related art, the transmission power of the scanning beam must be increased, which leads to the increase of the transmission power consumption of the base station and the reduction of the overall efficiency of the wireless system, and affects the user experience of the 5G network equipment.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The terminology used in the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.

The technical scheme provided by the disclosure is suitable for a 5G network or other network communication systems which use high-frequency beams for information transmission. The high-frequency beam is a beam with a frequency point in a frequency band of 6GHz or above. The execution body referred to in the present disclosure includes: the system comprises a transmitting end and a receiving end of a high-frequency beam, wherein the transmitting end of the high-frequency beam can be a base station, a sub-base station and the like provided with a large-scale antenna array. The receiving end of the high-frequency beam may be a User Equipment (UE) provided with a smart antenna array. The user equipment may be a user terminal, a user node, a mobile terminal or a tablet computer, an internet of things device, and the like. In a specific implementation process, the transmitting end and the receiving end of the high-frequency beam are independent and are simultaneously associated with each other, so that the technical scheme provided by the disclosure is implemented together.

According to the related knowledge, the user equipment must first perform cell search before accessing the network. That is to say, the user equipment needs to receive Primary and secondary Synchronization signals, namely PSS and SSS, which are sent by the base station through downlink, and perform downlink Synchronization, where the PSS is collectively called Primary Synchronization Signal, namely Primary Synchronization Signal; the SSS is called SecondarySynchronization Signal, i.e., the secondary synchronization Signal. Then, receiving cell system information transmitted by the base station through downlink, including: important information such as system bandwidth, system frame number, antenna port number, time frequency resource configuration and the like.

In the present disclosure, the primary and secondary synchronization signals and necessary system Information, such as MIB (Master Information Block) Information blocks, which the ue needs to receive, may be collectively referred to as a synchronization Information Block. In a 5G network, a base station uses a high-frequency beam carrying the synchronization information block to perform fast scanning on a preset area, so that user equipment in the area can receive the beam when the user equipment is located in a coverage area of the high-frequency beam, thereby demodulating the synchronization information block, performing corresponding synchronization and operation of reading system information, and preparing for a random access network.

In an application scenario of the present disclosure, with a base station as a center, a signal coverage area may include: the device comprises a first preset area and a second preset area outside the first preset area. The second preset area may only have non-delay-sensitive user equipment distributed therein, for example, mtc (massive Machine Type Communication) equipment, which is not sensitive to delay and can send data at a long interval.

Based on the above scenario, the present disclosure provides a method for transmitting a synchronization information block, which may be applied in a base station, the method including:

in step 11, transmitting a synchronization information block to user equipment in a first preset area in a beam scanning manner through a first beam;

in this disclosure, the user equipment in the first preset area may be a delay sensitive device and a non-delay sensitive device. 2-1 illustrates a schematic diagram of a scenario for transmitting a synchronization information block according to an example embodiment; fig. 2-2 is a schematic diagram illustrating another scenario for sending a synchronization information block according to an exemplary embodiment, which can be understood as a top view of fig. 2-1. When the base station 100 scans the first preset area through the first Beam, i.e., Beam 1, the delay requirement and the coverage requirement of each user equipment can be met.

In the present disclosure, the first beam and the second beam both belong to beams of a designated frequency band of the 5G network.

In step 12, the synchronization information block is transmitted to the target user equipment in a second preset area outside the first preset area through a second beam in a beam scanning manner.

In the present disclosure, as shown in fig. 2-1 and 2-2, the base station 100 may transmit a second Beam, Beam 2, to a second predetermined area located outside the first predetermined area, where the second Beam also carries the synchronization information block, and may transmit the synchronization information block to the UE4 located outside the first area.

In the present disclosure, the second beam differs from the first beam in the following features:

a first feature: transmitting power

In the present disclosure, the transmission power of the second beam is greater than the transmission power of the first beam, and therefore, the second beam may reach a farther area, that is, a second preset area, so that the base station may cover more terminals, thereby improving the coverage of the base station.

The second characteristic: interval of scanning period

In the present disclosure, the scanning period interval refers to a time interval between two adjacent scanning of the region by the same beam.

In the present disclosure, the scan period interval of the second wavenumber is greater than the scan period interval of the first wavenumber. Referring to fig. 3, a diagram illustrating two beam scanning features is shown in accordance with an exemplary embodiment. The first beam has a scan period interval of T1 and the second beam has a scan period interval of T2. As shown in fig. 3, it is assumed that the time interval T1 between the start time of the first scanning week and the start time of the second scanning week of the first beam is 5 ms; the time interval T2 between the start time of the first scanning cycle by the second beam and the start time of the second scanning cycle may be several times T1, for example, 50 ms.

In this disclosure, the non-delay-sensitive device in the second preset area, such as the mtc device, allows a longer time to wait for the synchronization information block, so that the synchronization information block may be acquired through the second beam, which has a smaller impact on the user experience of the device. If there is a delay sensitive device in the second preset area, it does not select to synchronize through the second beam because it requires low delay, and naturally does not belong to the user equipment that the base station can cover.

In the present disclosure, the scanning duration of the first beam and the second beam may be the same or different. The scanning duration refers to the dwell time of a beam at a coverage position. In order to meet the low delay requirement of the ue in the first predetermined area, the first beam may be scanned with a shorter scanning duration, for example, 25 μ s; the second beam may take a slightly longer scan duration, such as 50 mus.

Referring to fig. 2-2, which is a schematic top view of a Beam scanning diagram, a first Beam, Beam 1, scans for one week, so that

UEs

1, 2, 3, and UEn in a first preset area can receive a synchronization information block. Similarly, the second Beam, Beam 2, scans for a week, so that the non-delay sensitive device UE4 located in the second preset area can receive the synchronization information block, and therefore, the method for sending the synchronization information block provided by the present disclosure can increase the terminal coverage of the base station.

Because the scanning period interval T2 of the second beam is much greater than the scanning period interval T1 of the first beam, in the present disclosure, the duration of T2 may be several times the duration of T1, and even differ by one order of magnitude, therefore, the present disclosure may use the second beam with longer scanning period interval and larger power to send the synchronization information block to the area farther from the base station, improve the terminal coverage performance of the system under the condition of occupying less time domain resources, and save the system power consumption and wireless resources.

In addition, in another embodiment of the present disclosure, when the second beam carries the synchronization information block for beam scanning, the downlink synchronization signal and the necessary system information may be modulated by using a high-frequency beam of a specific frequency band in a time division multiplexing manner. Referring to fig. 4, a schematic diagram of the scanning duration of the second beam according to an exemplary embodiment, such as the high-power second beam shown in fig. 3, assuming that the scanning duration of one second beam is 50 μ s, in the present disclosure, the scanning duration of 50 μ s may be divided into a plurality of time units, such as 10 time units, each of which is 5 μ s, according to the time division multiplexing technique. The base station separately carries the downlink synchronization signal and the necessary system information according to a preset strategy, for example, the first 5 time units are used for carrying the downlink synchronization signal, and the last 5 time units are used for carrying the necessary system information. When receiving the second beam, the user equipment can firstly acquire the downlink synchronization signal for synchronization, and then receive and read the necessary system information, thereby reducing the time delay for the user equipment to acquire the necessary system information.

Referring to fig. 5, a flowchart of another method for transmitting a synchronization information block according to an example embodiment is shown, where the method may further include:

in step 13, according to a preset time period, counting the distribution condition of the user equipment in the first preset area;

in the disclosure, the ue may randomly access the network after receiving the synchronization information block, and the base station determines the device identifier of the ue according to an access request from the ue, where the device identifier may be any information capable of identifying the ue. For example, the Mobile terminal may be an International Mobile Equipment Identity (IMEI), a Subscriber Identity Module (SIM) card number, or the like. The base station may count the distribution of the user equipment within a preset time period according to the number of the recorded equipment identifiers.

Assuming that the preset time period is one month, the base station may determine the distribution of the user equipments in the area where the base station is located according to the user equipment access condition of each month recorded in half a year or one year.

In step 14, the scanning parameters of the first beam are adjusted according to the distribution of the user equipment.

In this disclosure, the distribution of the user equipment may be the access number of the user equipment. The base station may determine the geographic attribute of the area according to the access number of the user equipment, for example, whether the urban area with heavy traffic is a remote area, or the like. If the area where the base station is located belongs to the urban area, the scanning parameters of the first beam may be adjusted according to a preset strategy, for example, the scanning period interval of the first beam is shortened, for example, from original 5ms to 2ms, that is, beam scanning is started every 2ms, so as to improve the system efficiency and improve the access experience of the user equipment.

Referring to fig. 6, a flowchart of another method for transmitting a synchronization information block according to an exemplary embodiment is shown, and in another embodiment of the present disclosure, the method may further include:

in step 15, when the average access number of the user equipments in the first preset area in a preset time duration exceeds a preset threshold, the transmission of the second beam is turned off.

In the present disclosure, when the base station is obtained through statistical analysis: when the average access number of the UEs exceeds the preset threshold value for a preset time period, for example, during a day, the base stations are in a densely populated area, and in general, the base stations in these areas are distributed more densely, and it is not necessary to increase the number of terminals covered by the base station by transmitting the second beam, so the transmission of the second beam can be turned off. Thereby saving base station power consumption.

Referring to fig. 7, which is a flowchart illustrating another method for transmitting a synchronization information block according to an exemplary embodiment, in another embodiment of the present disclosure, the method may further include:

in step 16, detecting uplink data sent by the user equipment in the second preset area;

in this disclosure, after receiving the synchronization information block sent by the second beam, the ue in the second preset area may also need to configure parameters such as corresponding transmission power to realize random access to the base station, and then may send uplink data to the base station.

In step 17, if the uplink data sent by the user equipment in the second preset area is not detected within a preset time range, the transmission of the second beam is turned off.

For the base station, if the uplink data transmitted by the user equipment in the second preset area is not received for a long time, such as one month or half a year, the second beam setting is invalid. Under the condition, the base station can close the emission of the second wave beam, so that the power consumption of the base station is saved, and the waste of system wireless resources is avoided.

Correspondingly, the present disclosure also provides a method for acquiring a synchronization information block, which is applied in a user equipment, and a flowchart of a method for sending a synchronization information block is shown with reference to fig. 8 according to an exemplary embodiment, where the method may include:

in step 21, detecting a target beam carrying a synchronization information block;

in the present disclosure, the UE may receive the first target beam and/or the second target beam according to its own frequency domain resource configuration. The target beam carries a synchronization information block.

In step 22, determining a scanning period interval of the target beam according to the received target beam, and estimating a transmission power;

in this disclosure, the UE may determine the scanning period interval of the target beam according to the received target beam, and estimate the distance from the base station according to the signal strength of the received target beam, so as to estimate the transmission power required for uplink communication.

In step 23, if the device capability parameter of the ue matches the scanning time interval and the estimated power, the synchronization information block is demodulated.

In the embodiment of the present disclosure, when the user equipment is factory set, capability parameters of a general device are set by default, such as maximum transmission power, delay attribute information, time-frequency resource, and the like of the device.

Based on the characteristic that the beam attenuation in 5G communication is fast, if the ue is far away from the base station, even the uplink signal transmitted with the maximum transmission power cannot reach the base station, or the delay attribute information of the ue is not matched with the scanning period interval of the target beam, the base station and the ue cannot normally communicate with each other, and therefore, in this case, the synchronization information block carried by the target beam is not demodulated.

Also taking the UE4 in fig. 2-1 as an example, if the UE4 can achieve normal communication with the base station, the configuration information thereof needs to satisfy the following two conditions: firstly, the transmitting power of the UE4 is large enough to make the uplink information reach the base station; second, the time domain resource configuration of UE4 matches the scan period interval of the second beam. Otherwise, the user equipment does not demodulate the synchronization information block carried by the second beam.

While, for purposes of simplicity of explanation, the foregoing method embodiments have been described as a series of acts or combination of acts, it will be appreciated by those skilled in the art that the present disclosure is not limited by the order of acts, as some steps may, in accordance with the present disclosure, occur in other orders and concurrently.
