[0021] In related technologies, SSB (Synchronization Signal and PBCH Block) is configured for multiple transmitting units in a cell. However, in its configuration, considering that the terminal uses SSB and TRS (Tracing reference signal) for downlink frequency offset estimation and compensation, the two are configured with a QCL (Quasi Co Location) relationship, and accurate downlink channel quality is fed back to the base station through the bound TRS and CSI-RS (Channel State Information-Reference Signal). However, this configuration limits the maximum number of SSBs to 2, and it is impossible to configure more SSBs, making it impossible to achieve a one-to-one correspondence between SSB and transmitting units. The terminal cannot accurately evaluate the correspondence between wireless signals and transmitting units, which brings many inconveniences to the performance evaluation and fault location of the transmitting units.

[0022] To solve the above technical problems, an embodiment of the present disclosure provides a communication equipment maintenance method, which is applied to a transmitting unit of a signal transmitting device. The signal transmitting device can be a base station. The signal transmitting device includes multiple transmitting units, each of which is located in a merged cell. The transmitting unit can be an AAU (Active Antenna Unit). Each transmitting unit is configured with at least one SSB, and the SSBs corresponding to different transmitting units are not exactly the same. There is no quasi-co-location relationship between the SSB and the TRS. That is, each SSB is configured with a TRS that satisfies the QCL relationship with the SSB, that is, the SSB is decoupled from the TRS. Only in this way can the SSB be configured for each transmitting unit. Among the multiple transmitting units in the same merged cell, the beams emitted by at least some of the transmitting units constitute an overlapping beam group. The directions of any two beams in an overlapping beam group are different and overlap (that is, there is a coverage overlap area). When configuring SSBs for the transmitting unit, it should be ensured that at least all SSBs of any two beams in the partially overlapping beam group are different. Optionally, all SSBs of any two beams in all overlapping beam groups are different. It should be noted that the SSB can also be manually configured, that is, the SSB is manually configured for multiple transmitting units of the same merged cell, while at least ensuring that all SSBs of any two beams in the partially overlapping beams are different.

[0023] As shown in FIG1 , the communication equipment maintenance method includes the following steps S11 to S13 .

[0024] In step S11, multiple beams belonging to a merged cell are transmitted to the terminal; wherein at least two target beams in each beam form an overlapping beam group, and directions of at least two target beams in the overlapping beam group at least partially overlap.

[0025] Multiple transmitting units form a merged cell and share the same PCI (Physical Cell Identifier). All transmitting units (such as AAU) in the merged cell transmit beams, and each beam is configured with at least one SSB. Among the multiple beams, there is at least one overlapping beam group that includes multiple beams. The beams in the overlapping beam group are called target beams. Any two target beams in the overlapping beam group have different directions and overlap (that is, there is a coverage overlap area). It should be noted that each beam corresponds to an SSB, and the SSBs corresponding to any two target beams in the overlapping beam group are different, that is, the SSBs corresponding to each target beam in the overlapping beam group are different.

[0026] In step S12, the performance measurement parameters of the SSBs corresponding to the target beams sent by the receiving terminal are received, and the target SSB is determined from the SSBs corresponding to the target beams according to the performance measurement parameters.

[0027] The transmitting unit receives performance measurement parameters of multiple SSBs corresponding to each target beam in an overlapping beam group sent by the terminal, and determines a target SSB according to these performance measurement parameters, and the target SSB is the preferred SSB.

[0028] It should be noted that after determining the target SSB, there is no need to further determine the configuration of TRS and CSI-RS that satisfy the QCL relationship with the target SSB.

[0029] In step S13, a beam switching request is sent to the terminal, where the beam switching request is used to instruct the terminal to switch to the beam corresponding to the target SSB.

[0030] The transmitting unit sends a beam switching request to the terminal, which carries the identifier of the target SSB, so that the terminal can switch to the target SSB corresponding to the identifier. It should be noted that in the embodiment of the present disclosure, it is not necessary to configure a TRS that satisfies the QCL relationship with each SSB. Accordingly, the beam switching request does not need to carry relevant information about the QCL relationship.

[0031] In the embodiment of the present disclosure, the SSBs configured by the transmitting units with different transmitted beam directions and overlapping beams are not exactly the same. The base station determines a target SSB by measuring the performance results of multiple different SSBs received, and sends it to the terminal, so that the terminal estimates the frequency offset based on the preferred SSB. In this way, the terminal can determine the direction of the beam corresponding to the target SSB, and further accurately judge whether the frequency offset of the terminal is positive or negative, thereby obtaining an accurate frequency offset estimation result.

[0032] The communication equipment maintenance method provided by the embodiment of the present disclosure is applied to a signal transmitting device, which includes multiple transmitting units, each transmitting unit is located in a merged cell, each transmitting unit is respectively configured with at least one synchronization signal and a physical broadcast channel block (SSB), and the SSBs corresponding to different transmitting units are not exactly the same; the method includes: transmitting multiple beams belonging to a cell to a terminal; wherein at least two target beams in each beam form an overlapping beam group, and the directions of at least two target beams in the overlapping beam group at least partially overlap; receiving performance measurement parameters of the SSBs corresponding to each target beam sent by the terminal, determining the target SSB based on the performance measurement parameters; and sending a beam switching request to the terminal for the terminal to switch to the beam corresponding to the target SSB. In the cell merging scenario, by pre-decoupling the SSB from the TRS, the SSB can be associated with the transmitting unit, so that the terminal can switch to the beam corresponding to the target SSB. When performing maintenance such as fault location, the terminal can identify which transmitting unit the beam comes from, thereby achieving TRP-level maintenance.

[0033] FIG2 is a schematic diagram of the relationship between the beam, SSB and transmitting unit provided by an embodiment of the present disclosure. As shown in FIG2 , in special scenarios such as railways (such as high-speed railways) and highways, a linear chain network is adopted when deploying base stations, that is, installation poles (i.e., structures for installing transmitting units) are set along the railway or highway, and each installation pole is installed with at least two transmitting units. The directions of the beams emitted by at least two transmitting units on one installation pole are at a certain angle and at least partially overlap. As shown in FIG2 , AAU1 and AAU2 are located on the same pole, emitting beams back to back in two different directions. The coverage areas of different beams may overlap, that is, there is a coverage overlap area, and the terminal located in the coverage overlap area can receive multiple beams in different directions, such as a pair of opposing beams (i.e., two beams in opposite directions emitted by adjacent AAUs of adjacent installation poles, such as the beams of AAU2 and AAU3 and AAU4 and AAU5 in FIG2 ). The beams transmitted by AAU2 and AAU3 have different directions and have overlapping coverage areas. When the SSB corresponding to AAU2 (ie, SSB1) and the SSB corresponding to AAU3 (ie, SSB2) are different, the beams of AAU2 and AAU3 form an overlapping beam group.

[0034] The railway network uses cell merging networking, that is, multiple AAUs use the same Cell ID (cell identification code). The beams transmitted by multiple AAUs (i.e., AAU1 to AAU12) with the same Cell ID are configured with different SSBs. When the terminal moves quickly from AAU2 to AAU3, the beam received by the terminal is a mixture of beams transmitted by AAU2 and AAU3. Since the beams transmitted by all AAUs are configured with different SSBs, the terminal can determine which AAU the received SSB comes from.

[0035] In the case where the number of transmitting units in the merged cell is greater than the preset number, wherein the SSBs corresponding to the preset number of transmitting units are different and are single SSBs, the SSBs corresponding to the remaining transmitting units in the merged cell are combined SSBs, and the combined SSB is formed by combining two single SSBs. For 5G networks, the preset number can be 8. As shown in Figure 2, there are 12 transmitting units in a merged cell, wherein each of the first 8 transmitting units corresponds to an SSB, that is, AAU1-AAU8 correspond to SSB1-SSB8 respectively, and the SSBs corresponding to the 9th to 12th transmitting units AAU9-AAU12 are combined SSBs, that is, the SSB corresponding to AAU9 is a combined SSB formed by the combination of SSB0 and SSB1, the SSB corresponding to AAU10 is a combined SSB formed by the combination of SSB2 and SSB3, the SSB corresponding to AAU11 is a combined SSB formed by the combination of SSB4 and SSB5, and the SSB corresponding to AAU12 is a combined SSB formed by the combination of SSB6 and SSB7.

[0036] In a super cell with more than 8 AAUs, each physical site is configured with the same beam. Two AAUs within the physical site are distinguished by overlapping beams. For example, in an SC (cell merging) network, two AAUs at the same physical site are configured with the same SSB. For example, for physical site 1, AAU0-SSB0, AAU1-SSB0, and 7 are configured. For example, for physical site 2, AAU2-SSB1, AAU3-SSB1, and 7 are configured. For example, for physical site 3, AAU4-SSB2, AAU5-SSB2, and 7 are configured. For example, for physical site 4, AAU6-SSB3, AAU7-SSB3, and 7 are configured. For example, for physical site 5, AAU8-SSB4, AAU9-SSB4, and 7 are configured. For example, for physical site 6, AAU10-SSB5, AAU11-SSB5 and 7 are configured.

[0037] The network management configures the number of SSB beams. For super cells with 8 or fewer AAUs, the SSB beam configuration is based on the actual number of AAUs. For example, for a super cell with 6 AAUs, only the first 6 beams need to be configured. For a super cell with 8 AAUs, 8 beams need to be configured. Do not configure too many beams, as this will complicate subsequent analysis. For example, the beam configuration for a super cell with 6 AAUs is as follows: In SSBlock->SubBeamInfo:

[0038] subBeamValid=true in subBeamIndex=0;

[0039] subBeamValid=true in subBeamIndex=1;

[0040] subBeamIndex=2 in subBeamValid=true;

[0041] subBeamIndex=3 in subBeamValid=true;

[0042] subBeamIndex=4 in subBeamValid=true;

[0043] subBeamIndex=5 in subBeamValid=true;

[0044] subBeamIndex=6 in subBeamValid=false;

[0045] subBeamIndex=7 in subBeamValid=true;

[0046] The beam measurement information is defined as follows:

[0047] IntraFReselection->ssbToMeasure is changed to mediumBitmap

[0048] IntraFReselection->mediumBitmap is changed to 11111111

[0049] IntraFMeasObject->ssbToMeasure is changed to mediumBitmap

[0050] IntraFMeasObject->mediumBitmap is changed to 11111111

[0051] SsbMeasInfo->mediumBitmap is changed to 11111111

[0052] When the number of transmitting units in the merged cell is less than or equal to the preset number, each transmitting unit corresponds to a different SSB, and the SSB corresponding to each transmitting unit is a single SSB. If the number of transmitting units in the merged cell is less than or equal to 8, each transmitting unit corresponds to a different single SSB. For example, AAU1 corresponds to SSB0, and AAU2 corresponds to SSB1.

[0053] In a line super cell where the number of AAUs in the super cell is less than 8, AAUs and SSBs correspond one to one in SC networking, such as AAU0-SSB0, AAU1-SSB1, AAU2-SSB2, AAU3-SSB3, AAU4-SSB4, AAU5-SSB5, AAU6-SSB6, and AAU7-SSB7.

[0054] The network management configures the number of SSB beams. For super cells with 8 or fewer AAUs, the SSB beam configuration is based on the actual number of AAUs. For example, for a super cell with 6 AAUs, only the first 6 beams need to be configured. For a super cell with 8 AAUs, 8 beams need to be configured. Do not configure too many beams, as this will complicate subsequent analysis. An example of beam configuration for a super cell with 6 AAUs is shown in SSBlock-->SubBeamInfo:

[0055] subBeamValid=true in subBeamIndex=0;

[0056] subBeamValid=true in subBeamIndex=1;

[0057] subBeamIndex=2 in subBeamValid=true;

[0058] subBeamIndex=3 in subBeamValid=true;

[0059] subBeamIndex=4 in subBeamValid=true;

[0060] subBeamIndex=5 in subBeamValid=true;

[0061] subBeamIndex=6 in subBeamValid=false;

[0062] subBeamIndex=7 in subBeamValid=false;

[0063] The beam measurement information is defined as follows:

[0064] IntraFReselection->ssbToMeasure is changed to mediumBitmap

[0065] IntraFReselection->mediumBitmap is changed to 11111111

[0066] IntraFMeasObject->ssbToMeasure is changed to mediumBitmap

[0067] IntraFMeasObject->mediumBitmap is changed to 11111111

[0068] SsbMeasInfo->mediumBitmap is changed to 11111111

[0069] In order to achieve better terminal channel estimation and demodulation performance, in some embodiments, each transmitting unit adopts a channel state information reference signal CSI-RS multiple transmission mode.

[0070] After the cell is merged, each transmitting unit can use the CSI-RS multiple transmission mode. That is, all the merged transmitting units use the same set of CSI-RS resource configurations, the CSI beam adopts a single beam configuration, and the TRS configuration is turned off in the multiple transmission mode. In the code implementation, the SSB and TRS processes are decoupled to fully realize the free configuration of SSB.

[0071] In some embodiments, as shown in FIG3 , after sending the beam switching request to the terminal (i.e., step S13), the communication device maintenance method may further include the following steps:

[0072] Step S14, determining the target transmitting unit corresponding to the target SSB;

[0073] Step S15: Send downlink information to the terminal through the target transmitting unit.

[0074] After receiving a beam switching request, the terminal will perform beam switching, switching to the beam corresponding to the target SSB. In other words, at this time, the terminal can only receive data sent by the transmitting unit corresponding to the target SSB. If the base station transmits downlink data through the transmitting unit corresponding to other SSBs, the terminal may not be able to receive it, which will affect transmission efficiency and waste transmission resources. Therefore, to save transmission resources and improve transmission efficiency, the base station can send downlink information through the transmitting unit corresponding to the target SSB.

[0075] It should be noted that the downlink information here is all data that the base station needs to send to the terminal, including not only the service data that the base station needs to send to the terminal, but also other data with special purposes, such as CSI-RS used to obtain downlink channel quality.

[0076] In some embodiments, the performance measurement parameter is the reference signal received power, and determining the target SSB from the SSBs corresponding to each target beam based on the performance measurement parameter (i.e., step S12) includes the following steps: determining the SSB corresponding to the maximum value in the performance measurement parameter as the target SSB.

[0077] After receiving the performance measurement values ​​of multiple SSBs of multiple beams in the overlapping beam group sent by the terminal, the base station corresponding to the merged cell where the overlapping beam group is located determines that the SSB corresponding to the maximum value in the performance measurement parameter is the SSB with the best performance, that is, the target SSB (preferred SSB).

[0078] After determining the target SSB, the base station sends a beam switching request to the terminal. Upon receiving the beam switching request, the terminal performs beam switching, switching to the beam corresponding to the target SSB. In other words, the terminal needs to estimate the frequency offset based on the target SSB. If the target SSB performance does not meet the frequency offset estimation requirements, the effect will obviously be poor. On the other hand, if the requirements are met, the better the performance, the more accurate the frequency offset estimation result.

[0079] The disclosed embodiments are particularly suitable for scenarios such as high-speed trains and highways, where terminals typically move at high speeds. In these scenarios, the directions of the beams in an overlapping beam group are typically completely opposite and parallel to the terminal's direction of movement. Therefore, terminals typically experience significant frequency offset in these scenarios. Of course, the disclosed embodiments are also applicable to other scenarios, such as when the directions of the two beams in an overlapping beam group are not completely opposite, but at other angles; when three or more beams form an overlapping beam group; and when the terminal's direction of movement and the beam direction are not parallel, but at a certain angle.

[0080] In a merged cell scenario, the base station configures SSBs for multiple transmitting units belonging to the merged cell. Each transmitting unit is configured with at least one SSB, and each transmitting unit transmits a beam in a predetermined direction. Each beam has the SSB configured for its corresponding transmitting unit. At least two beams constitute an overlapping beam group. Any two beams in an overlapping beam group have different directions and overlap, and any two beams in each overlapping beam group have different SSBs. After configuring SSBs for multiple transmitting units in a merged cell, each SSB is also configured with a TRS decoupling mechanism that satisfies the QCL relationship with the SSB. During movement, the terminal detects the RSRP (Reference Signal Receiving Power) of different SSBs in the beam overlap area and reports it to the base station. The base station selects the target SSB corresponding to the terminal based on the measurement information reported by the terminal. The base station notifies the terminal to switch to the target SSB and only sends downlink data on the AAU corresponding to the target SSB. The terminal estimates the new frequency offset value based on the target SSB, periodically measures the channel quality reported by the CSI-RS, and implements TRP-level maintenance measurement in the cell merging networking scenario.

[0081] An embodiment of the present disclosure also provides a signal transmitting device, as shown in Figure 4, including a processing module 101, a transceiver module 102 and multiple transmitting units 103, each transmitting unit 103 is located in a merged cell, each transmitting unit 103 is respectively configured with at least one synchronization signal and a physical broadcast channel block SSB, and the SSBs corresponding to different transmitting units are not exactly the same, and there is no quasi-co-location relationship between the SSB and the tracking reference signal TRS.

[0082] The transmitting unit 103 is configured to transmit multiple beams belonging to a merged cell to the terminal; wherein at least two target beams in each of the beams form an overlapping beam group, and the directions of at least two target beams in the overlapping beam group at least partially overlap.

[0085] The transceiver module 102 is configured to send a beam switching request to the terminal, where the beam switching request is used to instruct the terminal to switch to the beam corresponding to the target SSB.
