SSB (Synchronization Signal and PBCH block) is one of the most important pilot channels used in 5G. It consists of three parts: PSS, SSS and PBCH (Physical Broadcast Channel).

The optional processing flow 200 of the cell synchronization method in the embodiment of this application is applied to network equipment, as shown in Figure 2. The processing flow 200 includes the following steps:

Step 201: Obtain the SSB sending pattern.

The SSB transmission pattern can be obtained by combining multiple SSB transmission fields. In this embodiment of the present application, the SSB transmission pattern may include at least two or more SSB transmission fields with different frequency domain positions.

An SSB transmission field may include: the sequence number of PSS and SSS, the frequency domain width (in kilohertz) of subcarrier No. 0 of the frequency band used by the cell from the subcarrier occupied by the SSB, or the number of subcarriers, that is, the frequency domain position of the SSB, The period of SSB transmission (the accuracy of the period can be determined according to the system accuracy, for example, it can be accurate to seconds or microseconds), and the duration of SSB transmission (the duration can be determined according to the system application needs, for example, it can be one hour or ten minutes).

In some embodiments, obtaining the SSB transmission pattern may include: receiving the SSB transmission pattern sent by the core network server. Here, the SSB transmission pattern can be stored in the core network server in advance.

In some embodiments, after the base station is powered on, the SSB transmission patterns of multiple cells of the base station are obtained. The method by which the base station obtains the SSB transmission pattern may include, for example: OAM (Operations Administration and Maintenance, Operations Management and Maintenance) to pass it to the base station; the core network server passes it to the base station; the industrial control server passes it to the base station through the core network server. Correspondingly, the SSB transmission pattern can be stored in OAM, core network server, and industrial control server in advance.

The core network server can send the SSB transmission pattern to the base station through signaling. It can be included in the existing signaling of the communication protocol between the core network server and the base station, such as cell establishment and cell reconstruction signaling; or it can be independent. Signaling, for example: SSB pattern transmission mode transmission. Its purpose is to notify the cell of the SSB transmission pattern, so that when the communication network receives strong external interference, the cell can change the SSB transmission in time, and the UE can continue to communicate with the cell (base station).

In some implementations, the network device sends the obtained SSB transmission pattern to the terminal device.

Step 202: Adjust the frequency domain position of the synchronization signal transmitted within a preset period according to the SSB transmission pattern.

In the embodiment of the present application, there is no specific limit on the length of the preset period, and it can be set according to actual system needs. It can be understood that the preset period may include multiple synchronization signal transmission periods.

The SSB transmission pattern includes multiple SSB transmission fields, and each SSB transmission field includes the PSS, the sequence number of the SSS, and the frequency domain location of the SSB.

In some optional embodiments, adjusting the frequency domain position of the synchronization signal sent within a preset period according to the SSB transmission pattern may include: within the preset period, determining according to the SSB transmission field corresponding to the target synchronization period in the SSB transmission pattern. The frequency domain position of the synchronization signal sent during the target synchronization period.

Optionally, the multiple SSB transmission fields in the SSB transmission pattern are arranged in the order of PSS and SSS sequence numbers, or the multiple SSB transmission fields in the SSB transmission pattern are arranged in the order of the SSB transmission period. The SSB transmission field corresponding to the target synchronization period in the SSB transmission pattern can be the SSB transmission field corresponding to the SSB transmission period corresponding to the target synchronization period, or it can be multiple transmission periods in which the transmission period of the target synchronization period is within the preset period. PSS corresponding to the sequence number, and SSB sending field corresponding to the SSS sequence number. It can be understood that the number of SSB transmission fields in the SSB transmission pattern is limited, and the SSB transmission fields in the SSB transmission pattern can be used cyclically within a preset period.

In some embodiments, after the cell is established, the SSB block frequency domain positions of the PSS and SSS are transmitted according to the SSB transmission pattern. In each transmission cycle, for example, a cycle is 5 minutes, the sequence of PSS and SSS does not change, and the frequency domain position of SSB also remains unchanged. In the next transmission cycle, new PSS and SSS sequences are transmitted according to the frequency domain position of the SSB transmission field corresponding to the SSB transmission pattern.

Another optional processing flow 300 of the cell synchronization method in the embodiment of this application is applied to terminal equipment. As shown in Figure 3, the processing flow 300 includes the following steps:

Step 301: Obtain the SSB sending pattern.

In this embodiment of the present application, the SSB transmission pattern obtained by the terminal device is the same as the SSB transmission pattern obtained by the network device.

In some optional embodiments, obtaining the SSB transmission pattern may include: receiving the SSB transmission pattern sent by the network device.

In some embodiments, after the UE accesses the cell to which the base station belongs, it can obtain the SSB transmission pattern by receiving messages from the base station. This message can be an RRC (Radio Resource Control) message or a message from the core network server.

The base station and the UE can exchange SSB transmission patterns through signaling. Here, the signaling can be included in the existing signaling after the UE accesses the cell described by the base station, such as: RRCrelease, RRCsetup; or it can be an independent signaling, such as: SSB pattern transmission, which is the signaling of the base station. Sent to the UE, the UE returns to the base station for confirmation after receiving it.

In some embodiments, the UE can update the location with the core network, and the core network server sends the SSB sending pattern to the UE by including the SSB sending pattern field in the identity registration signaling message.

Step 302: Adjust the frequency domain position of the received synchronization signal within a preset period according to the SSB transmission pattern.

In some embodiments, adjusting the frequency domain position of the received synchronization signal within a preset period according to the SSB transmission pattern may include: within the preset period, determining the target synchronization time according to the SSB transmission field corresponding to the target synchronization period in the SSB transmission pattern. The frequency domain position of the periodic reception synchronization signal.

In some embodiments, after the UE is powered on for the first time, since it does not obtain any prior information, it performs cell search, registration and location update supported by its own capabilities. After the registration and location update process, the UE obtains the SSB of the cell from the base station or the core network server and sends it dynamically. That is, the SSB block frequency domain positions of PSS and SSS are dynamically changed and sent according to the received SSB sending pattern: In each transmission cycle, for example, a cycle is 5 minutes, the sequence of PSS and SSS does not change, and the frequency domain position of SSB also remains unchanged. In the next transmission cycle, new PSS and SSS sequences are transmitted according to the fields of the SSB transmission pattern. Within a preset period, such as within 24 hours, the UE will always perform reception measurements of PSS and SSS sequences according to the obtained SSB transmission pattern at the frequency domain position corresponding to the transmission cycle of the corresponding base station, and then stay in this cell.

Continuing to refer to Figure 4, which shows an interactive process 400 of the cell synchronization method according to the embodiment of the present application. As shown in Figure 4, the interaction process 400 may include the following steps:

Step 401: The network device obtains the SSB transmission pattern.

Step 402: The terminal device obtains the SSB transmission pattern.

Step 403: The network device adjusts the frequency domain position at which the synchronization signal is sent within a preset period according to the SSB transmission pattern.

Step 404: The terminal device adjusts the frequency domain position of the received synchronization signal within a preset period according to the SSB transmission pattern.

For the specific content of the above-mentioned steps 401 to 404 and the technical effects thereof, please refer to the relevant descriptions of steps 201 to 202 and steps 301 to 302 of the corresponding embodiments in Figures 2 and 3 respectively, which will not be repeated here. Repeat.

In the embodiment of this application, because the SSB transmission frequency domain position of the base station changes dynamically, the strong interference that occurs randomly does not interfere with the full bandwidth and long time of the frequency domain. Therefore, even if strong interference occurs in the current transmission cycle, the UE will soon be in the next transmission period. In one cycle, another frequency domain location will correctly receive PSS and SSS to ensure the normal camping of the UE. At the same time, because the UE has the SSB sending pattern as a priori information, it also avoids the loss of computing resources of the UE due to blind detection or full-band retrieval, saving time and power of the UE.
