In order to greatly improve the channel capacity, the MIMO uses a plurality of antennas at both the transmitting end and the receiving end, and forms an antenna system with a plurality of channels between transmitting and receiving, thereby improving the channel capacity of the system by times without increasing the frequency spectrum resources and the antenna transmitting power.
Second, network searching processing in NR (New Radio, New air interface) system
In the NR system, the time domain position and the frequency domain position of SSB (Synchronization Signal and PBCH Block) are flexible and variable; in the frequency domain, the SSB is no longer fixed in the middle of the band; in the time domain, the location and number of SSBs transmitting may vary. In the NR system, the terminal device needs to perform coarse frequency offset and coarse time offset compensation by detecting a PSS (Primary Synchronization Signal) and a SSS (Secondary Synchronization Signal), and decode a pbch (physical Broadcast channel) to perform fine frequency offset and fine time offset compensation, so that the terminal device can finally achieve time Synchronization and frequency Synchronization with a base station belonging to a resident cell.
When a terminal device searches a network in an NR system, firstly, receiving SSBs of each cell, wherein the SSBs comprise a PSS, an SSS, a PBCH and the like; secondly, the terminal equipment acquires Cell ID (Cell identification) by detecting PSS and SSS in SSB of each Cell to determine the resident Cell, and performs coarse time offset and coarse frequency offset compensation to determine the time domain position and the frequency domain position of the SSB; thirdly, receiving PBCH according to the determined time domain position and frequency domain position of the SSB; then, the received PBCH is decoded to obtain information such as RSRP (Reference Signal Receiving Power), SINR (Signal Interference Noise Ratio), CTO (time Offset compensation), and CFO (Frequency Offset compensation) of an antenna for Receiving the SSB.

It should be noted that decoding the received PBCH includes: and decoding the MIB (Master Information block) to obtain Information such as RSRP, SINR, CTO, CFO and the like.
In a scene adopting an MIMO scheme, terminal equipment decodes PBCH received by each antenna to obtain information such as RSRP, SINR, CTO, CFO and the like corresponding to each antenna; each antenna receives the PBCH, which is the PBCH corresponding to the same cell, and the cell determines the cell where the terminal device resides.
The following describes the communication method and communication apparatus provided in the present application in detail:
referring to fig. 2, fig. 2 is a schematic flowchart of a communication processing method according to an embodiment of the present disclosure. As shown in fig. 2, the communication processing method includes the following steps 201 to 203. The method execution subject shown in fig. 2 may be a network device and a terminal device. Alternatively, the method execution subject shown in fig. 2 may be a chip in a network device and a chip in a terminal device. Fig. 2 illustrates a network device and a terminal device as examples. The main execution bodies of the subsequent flow charts have the same structure and are not described again. Wherein:
201. a network device sends an SSB, the SSB comprising a PSS, an SSS, and a PBCH.
Accordingly, the terminal device receives the physical broadcast channel PBCH through a plurality of antennas, including: the method comprises the steps that terminal equipment receives SSBs of a plurality of cells through a plurality of antennas, detects PSS and SSS in cell signals, determines the time domain position and the frequency domain position of the SSB corresponding to the cell where the terminal is to reside, and then receives the SSBs of the same cell through the plurality of antennas respectively according to the time domain position and the frequency domain position of the SSB, namely the SSBs of the cell where the terminal equipment is to reside.
202. And the terminal equipment decodes the PBCH received by the plurality of antennas to obtain a plurality of received signal qualities, wherein the plurality of received signal qualities are in one-to-one correspondence with the plurality of antennas.
The time domain position and the frequency domain position of the PBCH in the SSB are determined, and the terminal equipment can determine the PBCH from the SSB according to the time domain position and the frequency domain position of the PBCH so as to decode the PBCH in the SSB in a targeted manner.
In one possible implementation, the received signal quality may be SINR, or may be other parameters that may be used to indicate the received signal quality of the antenna.
In a possible implementation, the terminal device decodes the PBCH received through the multiple antennas, and further obtains information such as multiple RSRPs, multiple CTOs, and multiple CFOs, where the multiple RSRPs are in one-to-one correspondence with the multiple antennas, and the multiple CTOs are in one-to-one correspondence with the multiple antennas.
203. The terminal equipment determines a target time deviation Compensation (CTO) according to the quality of the plurality of received signals; wherein the target CTO is configured to adjust Timing (Timing) information of the plurality of antennas.
In an embodiment of the present application, the determining the target time offset compensation CTO according to the received signal qualities includes at least one of the following two cases:
the first condition is as follows: and if N received signal qualities in the plurality of received signal qualities meet a signal quality threshold condition, compensating the CTO according to N time deviations corresponding to the N received signal qualities, and determining a target CTO, wherein N is a positive integer.
The signal quality threshold condition is used to determine validity of the antenna corresponding to the received signal quality to receive the signal, that is, an antenna corresponding to the received signal quality meeting the signal quality threshold condition is an antenna capable of effectively receiving the signal, that is, an effective antenna, and an antenna corresponding to the received signal quality not meeting the signal quality threshold condition is an antenna which does not effectively receive the signal, for example: in scenarios where the antenna signal is bad and/or the antenna is not engaged (not operating) without a valid signal, the received signal quality of the antenna does not meet the signal quality threshold.
Case two: and if the quality of the plurality of received signals does not meet the signal quality threshold condition, determining a target CTO according to a plurality of CTOs corresponding to the quality of the plurality of received signals.
In this embodiment of the present application, the determining a target CTO according to a plurality of CTOs corresponding to the plurality of received signal qualities includes: determining a target CTO from a CTO set, wherein the CTO set comprises a plurality of CTOs corresponding to the plurality of received signal qualities; wherein the target CTO is less than or equal to any CTO in the CTO set except the target CTO.
In one possible implementation, the determining the target CTO from the CTO set includes: and sorting the plurality of CTOs corresponding to the plurality of received signal qualities in size, determining the CTO with the minimum value, and determining the CTO with the minimum value as the target CTO.
And determining the CTO with the minimum value among the CTOs as the target CTO under the condition that the quality of the received signals does not meet the signal quality threshold condition, so that the situation that the Timing information of the antennas is adjusted too much and the Timing tracking is carried out wrongly is avoided.
For example, the terminal device receives PBCH through three antennas, and decodes the PBCH received by the three antennas to obtain three received signal qualities; determining a target CTO according to two CTOs corresponding to two received signal qualities under the condition that two received signal qualities in the three received signal qualities meet a signal quality threshold condition; and under the condition that the three received signal qualities do not meet the signal quality threshold condition, determining the CTO with the minimum median value of the three received signal qualities corresponding to the three received signal qualities as the target CTO.
In an embodiment of the present application, the condition that the signal quality threshold is met includes at least one of:
(1) the received signal quality is greater than a first signal quality threshold;
(2) the received signal quality is within a signal quality threshold.
In one possible implementation, the first signal quality threshold may be set by the system or configured by higher layer signaling, such as: the first signal quality threshold may be 0, and is not limited herein.
In one possible implementation, the signal quality threshold range is bounded by a second signal quality threshold and a third signal quality threshold, the second signal quality threshold being a lower threshold of the signal quality threshold range, the third signal quality threshold being an upper threshold of the signal quality threshold range; the received signal quality being within a signal quality threshold comprises: the received signal quality is greater than or equal to the second signal quality threshold, and the received signal quality is less than or equal to the third signal quality threshold; the second signal quality threshold and the third signal quality threshold may be set by the system, or configured by higher layer signaling, or dynamically adjusted according to information obtained by decoding the received PBCH.
For example, the maximum value of the RSRPs is compared with a second maximum value, and when the maximum value is greater than the second maximum value of a preset multiple and the second maximum value is greater than a preset RSRP, the SINR corresponding to the second maximum value is used as a third signal quality threshold, and 0 is used as a second signal quality threshold, thereby eliminating the interference of the abnormal cell signal.
In this embodiment of the application, the determining the target CTO according to the N time offset compensations CTO corresponding to the N received signal qualities includes at least one of the following manners:
the first method is as follows: obtaining an average value of N CTOs corresponding to the N received signal qualities; and determining the average value of the N CTOs as a target CTO.
For example: n is 2, two CTOs corresponding to 2 received signal qualities are x and y, respectively, and (x + y)/2 is determined as a target CTO.
The second method comprises the following steps: determining N scaling factors according to the N received signal qualities, wherein the N scaling factors correspond to N CTOs corresponding to the N received signal qualities one by one; and determining the target CTO according to the N CTOs and the N proportionality coefficients.
In one possible implementation, the determining N scaling factors according to the N received signal qualities includes: and determining the ratio of the ith received signal quality to the sum of the N received signal qualities as the ith scaling factor, wherein the ith scaling factor corresponds to the ith received signal quality, and i is a positive integer.
For example, N is 3, the received signal quality of each of 3 antennas is X, Y, Z, the 1 st scaling factor is X/(X + Y + Z), the 2 nd scaling factor is Y/(X + Y + Z), and the 3 rd scaling factor is Z/(X + Y + Z); X/(X + Y + Z), Y/(X + Y + Z), and Z/(X + Y + Z) correspond to the received signal quality of X, Y, Z, respectively.
In one possible implementation, the determining a target CTO according to the N CTOs and the N scaling factors includes: and according to the N proportional coefficients, carrying out weighted summation on the N CTOs to obtain a target CTO.
The proportionality coefficient can reflect the validity and the reliability of a signal received by a corresponding antenna, the proportionality coefficient corresponding to the quality of the received signal with higher validity and reliability is increased, and the Timing tracking precision of the target CTO can be improved.
In one possible implementation, after steps 201 to 203, the communication processing method further includes:
204. and the terminal equipment adjusts the Timing information of the multiple antennas according to the target CTO so as to synchronize the Timing information of the multiple antennas with the Timing information of the network equipment, namely synchronize the Timing information of the multiple antennas with the Timing information of the resident cell.
In the embodiment of the application, effective antennas in the multiple antennas are determined according to the quality of multiple received signals of the multiple antennas, and the target CTO is determined according to the CTO corresponding to the effective antennas so as to compensate Timing of the multiple antennas, thereby improving Timing tracking precision in a network searching process.
