Description

Information reporting method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to an information reporting method and apparatus.

Background

Fifth Generation mobile communication technology (5G) is increasingly used. In order to fully utilize the bandwidth resource of 5G, a Time Division Duplex (TDD) mode may be adopted. The TDD mode is a communication mode in which uplink and downlink use the same frequency band and uplink and downlink use different time slots in one frequency band. When the frequency bands of the serving cell where the terminal device currently resides are the same as those of the neighboring cell, the neighboring cell and the serving cell are the same-frequency cells, wherein the neighboring cell is the same-frequency neighboring cell of the serving cell. In TDD network deployment, when the subframe boundary synchronization is kept between the same-frequency cells, and the uplink and downlink matching ratios configured in the same-frequency cells are the same, the synchronization is kept between the same-frequency cells. In the TDD mode, when synchronization is not maintained between the same-frequency cells, the terminal device cannot report the measurement result of the same-frequency neighboring cell to the access network device, and the same-frequency neighboring cell with strong signal quality may interfere with the signal of the serving cell, so that the terminal device resides in a cell with poor signal quality for a long time and cannot switch to the same-frequency neighboring cell with good signal quality.

Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

For a better understanding of the embodiments of the present application, the following description refers to terms of art to which the embodiments of the present application relate:

(one) same frequency adjacent region

When the frequency bands of the serving cell where the terminal device resides at present are the same as those of the neighboring cell, the neighboring cell and the serving cell are the same-frequency cells.

The adjacent cell is a same-frequency adjacent cell of the service cell. In TDD network deployment, when subframe boundary synchronization is maintained between co-frequency cells and uplink and downlink matching ratios configured in the co-frequency cells are the same, synchronization is maintained between the co-frequency cells, a serving cell is synchronized with an adjacent cell, and the adjacent cell is a co-frequency synchronization cell (synchronization cell for short) of the serving cell. When the subframe boundaries between the cells with the same frequency are not synchronous, or the uplink and downlink ratios configured in the cells with the same frequency are different, the serving cell is asynchronous with the adjacent cells, and the adjacent cells are the cells with the same frequency and asynchronous (called asynchronous cells for short) of the serving cell.

(two) Time Division Duplex (TDD) mode

The TDD mode is a communication mode in which a radio frequency point is shared for transceiving and the default network is basically synchronous, that is, the receiving and transmitting are in the same frequency channel, and different time slots are used for uplink and downlink in one frequency band, that is, the receiving and transmitting channels are separated by time. TDD network deployment requires maintaining accurate synchronization (microsecond level) of subframe boundaries between cells, and configuring the same uplink and downlink ratio in the same TDD synchronization cell.

(III) Synchronization Signal Block (SSB)

In a New Radio (NR) system, a network device needs to transmit a Synchronization Signal Block (SSB) for a terminal device to perform Synchronization, system information acquisition, measurement, and the like. The SSB is composed of three parts, namely, PrimARy Synchronization Signals (PSS), Secondary Synchronization Signals (SSS), and Physical Broadcast Channel (PBCH). The PSS and the SSS are used for downlink synchronization (including timing synchronization, frame synchronization and symbol synchronization) of the terminal equipment; the PSS and SSS are also used to acquire Cell Identity (CID) and measure Cell signal quality.

Specifically, the PSS is configured to acquire a Cell Identifier (CID), determine that a Cell communication mode is a time-division duplex (TDD) mode or a Frequency-division duplex (FDD) mode, and may also be used for time domain synchronization, such as Orthogonal Frequency Division Multiplexing (OFDM) symbol synchronization, time slot synchronization, and/or Frequency domain synchronization. The SSS is used to determine an Identity (ID) of a cell, and may also be used to measure signal quality of the cell, so that the terminal device and the access network device select a beam and perform RRM measurement according to a measurement result. The SSB associates one or more beams for carrying the random access message, and the access network device communicates with the terminal device through the cell corresponding to the SSB based on the beam associated with the SSB. Wherein the SSB maps the associated beam with a unique SSB index.

When the terminal device can determine the index of the SSB of the neighboring cell based on the stored correspondence between the frequency point and the SSB index and the frequency point of the SSB of the neighboring cell, it indicates that the serving cell and the neighboring cell are synchronous cells, and the terminal device can report the index of the SSB of the neighboring cell and a signal measurement result of the SSB to the access network device. When the terminal device cannot determine the index of the SSB of the neighboring cell, which indicates that the serving cell and the neighboring cell are asynchronous cells, the terminal device cannot report the index of the SSB of the asynchronous cell and a signal measurement result of the SSB to the access network device, and the co-frequency neighboring cell with high signal quality may interfere with the signal of the serving cell, so that the terminal device resides in the cell with poor signal quality for a long time and cannot be switched to the co-frequency neighboring cell with high signal quality.

The correspondence between the frequency point and the SSB index stored in the terminal device is the correspondence between the frequency point of the serving cell where the terminal device currently resides and the SSB index. The correspondence between the frequency point of the serving cell where the terminal device currently resides and the SSB index may be different from the correspondence between the frequency point of the serving cell where the terminal device historically resides and the SSB index.

As shown in table 1, the correspondence between the frequency point of the terminal device storage serving cell 174 and the index of the SSB is: the serving cell 174 includes 8 frequency point ranges and indexes of corresponding SSBs, where an index of the SSB corresponding to a frequency point between [168, 936] is 0, an index of the SSB corresponding to a frequency point between [1812, 2580] is 1, an index of the SSB corresponding to a frequency point between [4008, 4776] is 2, an index of the SSB corresponding to a frequency point between [5652, 6420] is 3, an index of the SSB corresponding to a frequency point between [7848, 8616] is 4, an index of the SSB corresponding to a frequency point between [9492, 10260] is 5, an index of the SSB corresponding to a frequency point between [ 88, 12456] is 6, and an index of the SSB corresponding to a frequency point between [13332, 14100] is 7.

TABLE 1 correspondence between frequency points of serving cell 174 and indexes of SSBs

Indexing of SSBs	Frequency point
0	[168，936]
1	[1812，2580]
2	[4008，4776]
3	[5652，6420]
4	[7848，8616]
5	[9492，10260]
6	[11688，12456]
7	[13332，14100]

The frequency point of the SSB of the neighboring cell 420 is 170, and the terminal device determines that the frequency point 170 of the SSB of the neighboring cell 420 is between [168, 936] and the index of the corresponding SSB is 0 based on the correspondence between the 8 frequency points of the serving cell 174 and the SSB index shown in table 1 and the frequency point of the SSB of the neighboring cell 420. The terminal device determines that the index of the SSB of the neighbor cell 420 is 0. The terminal device can determine the index of the SSB of the neighboring cell 420 according to the correspondence in table 1, which indicates that the neighboring cell 420 and the serving cell 174 are synchronous cells.

The frequency point of the SSB of the neighbor cell 419 is 1000. Based on the correspondence between the 8 frequency points of the serving cell 174 and the SSB indexes shown in table 1, the terminal device cannot determine the SSB index of the neighboring cell 419 according to the correspondence in table 1 if the frequency point 1000 of the neighboring cell 419 is not within the range of the 8 frequency points in table 1, which indicates that the neighboring cell 419 and the serving cell 174 are asynchronous cells.

Signal measurement of (tetra) synchronization signal block SSB

The signal measurements of the SSBs are indicative of the signal quality of the SSBs, and the signal measurements of the SSBs include one or more of the following parameters: reference Signal Received Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Signal Received Quality (RSRQ), and Signal to interference noise ratio (SINR).

The RSRP is used for reflecting the path loss strength of the current channel and is used for measuring cell coverage and cell selection/reselection and switching; the RSSI is used for reflecting the received signal strength and the interference degree of the current channel; the RSRQ is used for reflecting and indicating the signal-to-noise ratio and the interference level of the current channel quality; the SINR is used to reflect the link quality of the current channel, and is an important index for measuring the performance parameters of the terminal device.

Signal measurements are the basis for mobility management, which is an important component in wireless mobile communications. Mobility management is to ensure that the communication link between the access network device and the terminal device is not interrupted by movement of the terminal device. The method can be divided into an idle state mobility management part and a connection state mobility management part according to the state of the terminal equipment. In the idle state, mobility management mainly refers to a Cell selection/reselection (Cell selection/reselection) process, and in the connected state, mobility management mainly refers to Cell handover (handover). Whether cell selection/reselection or handover, is based on the results of signal measurements.

(V) Physical Broadcast Channel (PBCH)

PBCH is used for radio frame number synchronization and configuration of SIB 1. The PBCH carries a demodulation reference signal (DMRS) required for demodulating the PBCH and a Master Information Block (MIB) for acquiring cell parameter information. Here, an index of SSB (SSB index) can be obtained by analyzing the DMRS. The terminal device reports the SSB signal measurement result to the access network device through the SSB index, and the access network device determines the SSB-associated beam for receiving data based on the SSB index.

The MIB includes necessary parameter configuration information required for parsing the SIB1, for example, the MIB includes information about the sub-carrier spacing applied to the SIB1, scheduling information of the SIB 1. The SIB1 includes timer and constant information for use by the terminal device in the idle and connected states. The SIB1 scheduling information is obtained by parsing the MIB in PBCH, and the cell parameter information can be obtained by receiving the SIB1 of the cell based on the SIB1 scheduling information. The parameter information of the cell includes, but is not limited to: bandwidth, frame number, subframe number, frequency point frequency band, etc. of the cell. The terminal equipment determines whether the cell can reside or not based on the parameter information of the cell obtained by analyzing the MIB and the SIB 1.

The method provided by the embodiment of the application is applied to a wireless communication system. The method provided by the embodiment of the application can be applied to various communication systems, for example, an internet of things (IoT) system, a narrowband band internet of things (NB-IoT) system, a Long Term Evolution (LTE) system, a fifth generation (5th-generation, 5G) communication system, a hybrid architecture of LTE and 5G, a 5G New Radio (NR) system, a new communication system appearing in future communication development, and the like.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terms "comprises" and "comprising," and any variations thereof, in the description and claims of this invention and the above-described drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or modules is not limited to the listed steps or modules but may alternatively include other steps or modules not listed or inherent to such process, method, article, or apparatus.

For example, the terminal device may also be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), or the like. Common terminal devices include, for example: the mobile terminal includes a mobile phone, a tablet computer, a notebook computer, a handheld computer, a Mobile Internet Device (MID), and a wearable device, such as a smart watch, a smart bracelet, a pedometer, and the like, but the embodiment of the present application is not limited thereto.

The embodiment of the application provides an information reporting method and an information reporting device, which can report the measurement result of a same-frequency neighboring cell in time when synchronization is not kept between the same-frequency cells in a TDD mode. The information reporting method provided in the embodiments of the present application is further described in detail below:

referring to fig. 2, fig. 2 is a schematic flow chart of an information reporting method according to an embodiment of the present disclosure. As shown in fig. 2, the information reporting method includes the following steps S201 to S203. The main body of the method execution shown in fig. 2 is the terminal device, or the main body may be a chip in the terminal device. Wherein:

s201, the terminal device decodes a physical broadcast channel PBCH in a first synchronization signal block SSB sent by a first co-frequency adjacent cell of the terminal device to obtain an index of the first SSB, and the first co-frequency adjacent cell adopts a time division duplex mode for communication; the first co-frequency adjacent cell is asynchronous with the service cell of the terminal equipment.

In the embodiment of the application, the first co-frequency adjacent cell is a co-frequency adjacent cell adjacent to a serving cell where the terminal device currently resides. The PBCH carries a demodulation reference signal (DMRS) required for demodulating the PBCH, a master information block MIB for acquiring cell parameter information, and SIB 1. The terminal device may decode the DMRS carried by the PBCH in the first SSB to obtain an index of the first SSB. Optionally, the terminal device may analyze the MIB and the SIB1 carried by the first PBCH to obtain the parameter information of the first co-frequency neighboring cell. And the terminal equipment determines whether the first co-frequency adjacent cell can reside or not based on the parameter information of the first co-frequency adjacent cell.

In the embodiment of the application, each same-frequency adjacent cell comprises one or more synchronous signal blocks SSB. Each synchronization signal block SSB consists of one PSS, one SSS and one PBCH, and the terminal equipment decodes the DMRS carried by the PBCH to obtain the index of the SSB. Each SSB index is associated with an identification (beam ID) of a beam used for co-frequency neighbor communications. When the number of the first synchronization signal blocks SSB sent by the first synchronization neighboring cell is multiple, the terminal device decodes the DMRS carried by the PBCH in each first synchronization signal block SSB, respectively, to obtain the indexes of the multiple first SSBs. The index of each first SSB is associated with a different beam identification.

For example, two first synchronization signal blocks SSB are sent by the first peer-to-peer neighbor, which are SSB1 and SSB2, see the SSB structure diagram shown in fig. 3, where the SSB1 is composed of PSS1, SSS1, and PBCH1, and the SSB2 is composed of PSS2, SSS2, and PBCH 2. The terminal equipment decodes DMRS1 carried by PBCH1 to obtain the index of SSB1, and the terminal equipment decodes DMRS2 carried by PBCH2 to obtain the index of SSB 2. The index of SSB1 correlates to the identity of beam 1 and the index of SSB2 correlates to the identity of beam 2.

The terminal equipment analyzes the master information block MIB carried by the PBCH in the SSB1 and the SSB2 to obtain the scheduling information of the SIB1, receives the SIB1 of the first common-frequency neighboring cell 419 based on the scheduling information of the SIB1, and analyzes the SIB1 of the first common-frequency neighboring cell 419 to obtain the parameter information (including the parameter information of the cell, such as the bandwidth, the frame number, the subframe number, and the frequency band).

S202, the terminal device measures the first SSB to obtain a signal measurement result of the first SSB.

It should be noted that the execution sequence of step S202 and step S201 is not sequential. Step S202 may be executed simultaneously with step S201, step S202 may also be executed before step S201, and step S202 may also be executed after step S201, which is not limited in this embodiment of the application.

In one implementation, the terminal device measures the first SSB to obtain a signal measurement result of the first SSB, where the signal measurement result of the first SSB includes one or more of the following parameters: reference signal received power, RSRP, received signal strength indication, RSSI, reference signal received quality, RSRQ, and signal to interference and noise ratio, SINR. The signal measurement result of the first SSB may further include other parameters, and the embodiment of the present application is not limited thereto.

S203, the terminal device reports the signal measurement result of the first SSB and the index of the first SSB to the access network device.

Accordingly, the access network device may receive the signal measurement of the first SSB with the index of the first SSB. After the access network device receives the index of the first SSB and the signal measurement result, if the signal measurement result (representing the signal quality of the first common-frequency neighboring cell) of the first SSB satisfies the preset switching condition, the access network device switches from the serving cell to the first common-frequency neighboring cell. The access network equipment determines a beam for transmitting data based on the beam identification associated with the index of the first SSB. The preset handover condition may be that the signal quality of the first co-frequency neighboring cell is better than the signal quality of the serving cell.

For example, the terminal device reports the index of the SSB1 of the first co-frequency neighboring cell 419 and the signal measurement result of the SSB1 to the access network device, and if the signal measurement result of the SSB1 meets the preset switching condition, the access network device switches from the serving cell to the first co-frequency neighboring cell. And determines the beam used to transmit the data to be beam 1 based on the identification of beam 1 associated with the index of SSB 1.

In an implementation manner, the terminal device obtains a reporting condition for screening the first co-frequency neighboring cell, where the reporting condition may be that signal quality indicated by a signal measurement result of the first SSB satisfies a preset value. The terminal equipment determines whether the parameter information of the first co-frequency adjacent cell meets the reporting condition or not based on the parameter information of the first co-frequency adjacent cell obtained by analyzing the MIB and the SIB1 of the first co-frequency adjacent cell. If the reporting condition is met, indicating that the first co-frequency neighboring cell can reside, the terminal device reports the index of the first SSB of the first co-frequency neighboring cell and the signal measurement result to the access network device. The access network device may be an access network device corresponding to a serving cell, or an access network device corresponding to a first co-frequency neighboring cell.

Specifically, when there is one first synchronization signal block SSB of the first co-frequency neighboring cell and the only first SSB obtained by decoding the first PBCH meets the reporting condition, the terminal device reports the index of the first SSB and the signal measurement result to the access network device. When the number of the first synchronization signal blocks SSB of the first co-frequency neighboring cell is multiple and the PBCH in the first SSB is decoded to obtain multiple first SSBs, the terminal device reports the index of the first SSB and the signal measurement result that satisfy the reporting condition to the access network device.

In an implementation manner, when there are multiple indexes and signal measurement results of the first SSBs reported by the terminal device to the access network device, the access network device determines a target first SSB among the multiple first SSBs based on signal qualities of the multiple first SSBs. And the access network equipment determines the beam for transmitting the data according to the beam identification associated with the index of the target first SSB.

For example, the terminal device reports the index of the SSB1, the signal measurement result of the SSB1, the index of the SSB2, and the signal measurement result of the SSB2 of the first co-frequency neighboring cell to the access network device, and the access network device switches from the serving cell to the first co-frequency neighboring cell. Wherein the signal quality of the SSB1 is better than the signal quality of the SSB2, and the access network device determines the SSB1 as the target first SSB. The access network device determines the beam used for transmitting data to be beam 1 according to the identification of beam 1 associated with the index of SSB 1.

The terminal equipment decodes PBCH in SSB sent by the asynchronous cell in a TDD mode to obtain the index of the SSB of the asynchronous cell, and can report the measurement result of the asynchronous cell in time so as to switch to a neighboring cell with the same frequency and good signal quality.

Referring to fig. 4, fig. 4 is a schematic flowchart of another information reporting method provided in the embodiment of the present application. As shown in fig. 4, the information reporting method includes steps S401 to S407:

s401, the terminal device determines that the first co-frequency adjacent cell is asynchronous with the service cell of the terminal device.

In this embodiment, the terminal device may determine that the first common-frequency neighboring cell is asynchronous with the serving cell of the terminal device based on the stored correspondence between the frequency point and the index of the SSB and the frequency point of the first SSB. Specifically, the terminal device obtains a first SSB of a first common frequency neighboring cell, and determines a frequency point of the first SSB based on a first PSS and a first SSS in the first SSB. And if the frequency point of the first SSB is in the nth frequency point range of the service cell, determining that the first common-frequency adjacent cell is synchronous with the service cell of the terminal equipment, and determining that the SSB index corresponding to the nth frequency point range of the service cell is the index of the first SSB. And if the frequency point of the first SSB is not in the range of the n frequency points of the service cell, determining that the first common-frequency adjacent cell is asynchronous with the service cell of the terminal equipment.

For example, the terminal device obtains the first SSB of the first on-frequency neighbor 419, and determines that the frequency point of the first SSB is 1000 based on the first PSS and the first SSS in the first SSB. The terminal device determines that the first on-frequency neighboring cell 419 is asynchronous with the serving cell 174 based on the correspondence between the 8 frequency points of the serving cell 174 and the SSB indexes shown in table 1, and the frequency point of the first SSB is not within the frequency point range corresponding to the indexes 0 to 7 of the SSB.

S402, the terminal equipment decodes a physical broadcast channel PBCH in a first synchronous signal block SSB sent by a first co-frequency adjacent cell of the terminal equipment to obtain an index of the first SSB, the first co-frequency adjacent cell adopts a time division duplex mode for communication, and the first co-frequency adjacent cell is asynchronous with a service cell.

It should be noted that, for the execution process of step S402, reference may be made to specific description of the terminal device in step S201 in fig. 2 for decoding the physical broadcast channel PBCH in the first synchronization signal block SSB, and details are not described here again.

And S403, the terminal device measures the first SSB to obtain a signal measurement result of the first SSB.

It should be noted that, the execution process of step S403 may refer to the specific description in step S202 in fig. 2, and is not described herein again.

S404, the terminal device reports the signal measurement result of the first SSB and the index of the first SSB to the access network device.

It should be noted that, for the execution process of step S404, reference may be made to specific description that the terminal device reports the signal measurement result of the first SSB and the index of the first SSB to the access network device in step S203 in fig. 2, and details are not described here again.

S405, the terminal device decodes the physical broadcast channel PBCH in a second synchronization signal block SSB sent by a second same-frequency adjacent cell of the terminal device to obtain an index of the second SSB, and the second same-frequency adjacent cell is synchronous with a service cell of the terminal device.

In one implementation, the second co-frequency neighboring cell is a synchronous neighboring cell measured after the first co-frequency neighboring cell. The terminal device decodes a physical broadcast channel PBCH in a second synchronization signal block SSB (the second synchronization signal block SSB may be one or more) sent by a second co-frequency neighboring cell of the terminal device, so as to obtain an index of the second SSB. Specifically, the terminal device decodes the DMRS carried by the second PBCH to obtain an index of the first SSB, and analyzes the MIB and the SIB1 carried by the first PBCH to obtain parameter information of the first co-frequency neighboring cell. And the terminal equipment determines whether the second same-frequency adjacent cell can reside or not based on the parameter information of the second same-frequency adjacent cell. That is, the terminal device measures the first asynchronous cell and all the synchronous cells therebehind, and obtains the indexes of the SSBs of the first asynchronous cell and all the synchronous cells therebehind by using the method of decoding the PBCH of the SSBs.

In an implementation manner, when a plurality of second synchronization signal blocks SSB are sent by the second co-frequency neighboring cell, the terminal device decodes DMRS carried by the PBCH in each second synchronization signal block SSB, respectively, to obtain indexes of the plurality of second SSBs and parameter information of the second co-frequency neighboring cell. The index of each second SSB is associated with a different beam identification. For example, when there are two second synchronization signal blocks SSB sent by the second co-frequency neighboring cell, which are SSB3 and SSB4, respectively, the terminal device decodes PBCH in SSB3 and SSB4, and obtains an index of SSB3, an index of SSB4, and parameter information of the second co-frequency neighboring cell.

S406, the terminal device measures the second SSB to obtain a signal measurement result of the second SSB.

It should be noted that the execution sequence of step S406 and step S405 is not sequential. Step S406 may be executed simultaneously with step S405, step S406 may also be executed before step S405, and step S406 may also be executed after step S405, which is not limited in this embodiment of the application.

And S407, the terminal device reports the signal measurement result of the second SSB and the index of the second SSB to the access network device.

In one implementation, the terminal device obtains a reporting condition of a second co-frequency neighboring cell for screening and reporting. The terminal equipment determines whether the parameter message of the second same-frequency neighboring cell meets the reporting condition or not based on the parameter information of the second same-frequency neighboring cell obtained by analyzing the MIB and the SIB1 of the second same-frequency neighboring cell. If the reporting condition is met, indicating that the second same-frequency neighboring cell can reside, the terminal device reports the index of the second SSB of the second same-frequency neighboring cell and the signal measurement result to the access network device.

Specifically, when there is one second synchronization signal block SSB of the second co-frequency neighboring cell and the only second SSB obtained by decoding the second PBCH meets the reporting condition, the terminal device reports the index of the second SSB and the signal measurement result to the access network device. When a plurality of second synchronization signal blocks SSBs of a second co-frequency neighboring cell are available and a plurality of second SSBs are obtained by decoding the PBCH in the second SSBs, the terminal device reports the index of the second SSB and the signal measurement result that satisfy the reporting condition to the access network device.

Correspondingly, after the access network device receives the index of the first SSB and the signal measurement result reported by the terminal device, the index of the second SSB and the signal measurement result, the access network device switches from the serving cell to the neighboring cell corresponding to the SSB satisfying the switching condition. The handover conditions may be: and the SSB with the best signal quality in the signal measurement result of the first SSB, the signal measurement result of the second SSB and the signal measurement result of the SSB of the serving cell.

If the signal measurement result (representing the signal quality of the first co-frequency adjacent cell) of the first SSB is optimal, the serving cell is switched to the first co-frequency adjacent cell, and the beam for transmitting data is determined based on the beam identifier associated with the index of the first SSB of the first co-frequency adjacent cell. When the index of the first SSB is multiple, the access network may select the beam corresponding to the first SSB with the best signal quality.

And if the signal measurement result (representing the signal quality of the second same-frequency adjacent cell) of the second SSB is optimal, switching from the serving cell to the second same-frequency adjacent cell. And determining the beam for transmitting the data based on the beam identifier associated with the index of the second SSB of the second same-frequency adjacent cell. When the index of the second SSB is multiple, the access network may select the beam corresponding to the second SSB with the best signal quality.

And if the signal measurement result of the SSB of the serving cell is optimal, continuing to reside in the current serving cell.

For example, the terminal device reports the index of the SSB1, the signal measurement result of the SSB1, the index of the SSB2, and the signal measurement result of the SSB2 of the first co-frequency neighboring cell, and the index of the SSB3, the signal measurement result of the SSB3, the index of the SSB4, and the signal measurement result of the SSB4 of the second co-frequency neighboring cell to the access network device. Wherein, according to the signal measurement result of each SSB, the signal quality from strong to weak is determined as follows: SSB1> SSB2> SSB3> SSB4> SSB of the serving cell. The access network device switches to the first co-frequency adjacent cell and determines a beam for transmitting data based on the beam identifier associated with the index of the SSB 1.

The first common-frequency neighbor cell is an asynchronous cell measured by the terminal equipment, the second common-frequency neighbor cell is a synchronous cell measured after the first common-frequency neighbor cell, and the terminal equipment decodes PBCH in SSB sent by the first common-frequency neighbor cell to obtain an index of the first SSB; and the terminal equipment decodes the PBCH in the SSB sent by the synchronous cell measured after the first common frequency adjacent cell to obtain the index of the second SSB. That is, the terminal device decodes the PBCH in the measured SSB of the first asynchronous cell to obtain the index of the first SSB; in the synchronous cell measured after the asynchronous cell, the terminal equipment decodes the PBCH in the SSB sent by the terminal equipment to obtain the index of a second SSB; in the asynchronous cell measured after the asynchronous cell, the terminal device also decodes the PBCH in the SSB sent by the terminal device, and obtains the index of the SSB. The terminal equipment does not need to judge whether the common-frequency cell measured after the first asynchronous cell is a synchronous cell or an asynchronous cell, and obtains the SSB index of the cell by decoding the PBCH in the SSB according to the processing modes of the asynchronous cell, thereby simplifying the process, having high feasibility and simple control process.

Through the information reporting method described in fig. 4, the terminal device determines that the first frequency-sharing neighboring cell is asynchronous with the serving cell of the terminal device, decodes the physical broadcast channel PBCH in the first synchronization signal block SSB sent by the first frequency-sharing neighboring cell to obtain the index of the first SSB, and reports the signal measurement result of the first SSB and the index of the first SSB to the access network device. The terminal equipment decodes the PBCH in a second synchronous signal block SSB sent by a second same-frequency adjacent cell to obtain an index of the second SSB, and the second same-frequency adjacent cell is synchronous with the serving cell; and the terminal equipment reports the signal measurement result of the second SSB and the index of the second SSB to the access network equipment. That is, the terminal device does not need to determine whether the second co-frequency neighboring cell is a synchronous cell or an asynchronous cell, and for all the co-frequency cells measured after the first asynchronous cell, no matter the cells are synchronous cells or asynchronous cells, the PBCH in the SSB is decoded to obtain the index of the SSB of the cell according to the processing mode of the asynchronous cell. The process is simplified, the feasibility is high, and the control process is simple.

That is, the terminal device only decodes the PBCH in the SSB sent by the asynchronous cell, and obtains the index of the SSB of the asynchronous cell. For a new common-frequency cell, the terminal equipment firstly judges whether the common-frequency cell is a synchronous cell. If yes, the index of the SSB of the common-frequency cell is preferentially determined based on the corresponding relation between the frequency point and the SSB index stored in the terminal equipment and the frequency point of the common-frequency cell.
