SSB (Synchronization Signal and PBCH block) is one of the most important pilot channels used in 5G, and is composed of PSS, SSS, and PBCH (Physical Broadcast Channel).
An optional processing flow 200 of the cell synchronization method in the embodiment of the present application is applied to a network device, as shown in fig. 2, the processing flow 200 includes the following steps:
step 201, acquiring an SSB transmission pattern.
The SSB transmission pattern may be combined from a plurality of SSB transmission fields. In the embodiment of the present application, the SSB transmission pattern may include at least two or more SSB transmission fields with different frequency domain positions.
One SSB send field may include: sequence numbering of PSS and SSS, frequency domain width (in kHZ) of a subcarrier occupied by the SSB from a subcarrier No. 0 of a cell use band, or the number of subcarriers, that is, frequency domain position of the SSB, time period of SSB transmission (precision of the time period may be determined according to system precision, for example, may be accurate to seconds or microseconds), and time duration of SSB transmission (time duration may be determined according to system application needs, for example, may be one hour or ten minutes).
In some embodiments, obtaining the SSB transmission pattern may include: and receiving an SSB sending pattern sent by a core network server. Here, the SSB transmission pattern may be previously stored in the core network server.
In some embodiments, after the base station is powered on, the SSB transmission patterns of the plurality of cells of the base station are obtained. The manner for acquiring the SSB transmission pattern by the base station may include: OAM (Operations Administration and Maintenance) is transmitted to the base station; the core network server transmits the information to the base station; the industrial control server is transmitted to the base station through the core network server. Correspondingly, the SSB transmission pattern may be pre-stored in the OAM, the core network server, the industrial control server.
The core network server may send the SSB transmission pattern to the base station through signaling, which may be included in signaling existing in a communication protocol between the core network server and the base station, for example: cell establishment and cell reconstruction signaling; alternatively, it may be a separate signaling, such as: SSB pattern transmission mode transmission. The purpose is to inform the SSB sending pattern of the cell so that when the communication network receives strong external interference, the cell changes the sending of the SSB in time and the UE can continue to communicate with the cell (base station).
In some embodiments, the network device sends the obtained SSB sending pattern to the terminal device.
Step 202, adjusting the frequency domain position of the transmitted synchronization signal in a preset period according to the SSB transmission pattern.
In the embodiment of the application, the duration of the preset period is not specifically limited, and can be set according to the actual system requirements. It is understood that the preset period may include a plurality of transmission periods of the synchronization signal.
The SSB transmission pattern includes a plurality of SSB transmission fields, each SSB transmission field including a PSS, a sequence number of an SSS, and a frequency domain location of an SSB.
In some optional embodiments, adjusting the frequency domain position of the transmission synchronization signal within the preset period according to the SSB transmission pattern may include: and in a preset period, determining the frequency domain position of the synchronization signal transmitted in the target synchronization period according to the SSB transmission field corresponding to the target synchronization period in the SSB transmission pattern.
Optionally, the plurality of SSB transmission fields in the SSB transmission pattern are arranged in sequence of PSS and SSS sequence numbers, or the plurality of SSB transmission fields in the SSB transmission pattern are arranged in sequence of SSB transmission periods. The SSB transmission field in the SSB transmission pattern corresponding to the target synchronization cycle may be an SSB transmission field corresponding to a SSB transmission period corresponding to the target synchronization cycle, or may be an SSB transmission field corresponding to a PSS sequence number or an SSS sequence number corresponding to a sequence number of a plurality of transmission cycles of the target synchronization cycle within a preset cycle. 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 recycled within a preset period.
In some embodiments, after cell establishment, the frequency domain locations of the SSB blocks of the PSS, SSS are transmitted according to an SSB transmission pattern. In each transmission period, for example, one period is 5 minutes, the sequence of PSS and SSS is not changed, and the frequency domain position of SSB is also kept unchanged. And in the next transmission period, transmitting new PSS and SSS sequences according to the frequency domain position of the SSB transmission pattern corresponding to the SSB transmission field.
Still another optional processing flow 300 of the cell synchronization method in the embodiment of the present application is applied to a terminal device, as shown in fig. 3, where the processing flow 300 includes the following steps:
step 301, an SSB transmission pattern is obtained.
In the embodiment of the present application, the SSB transmission pattern acquired by the terminal device is the same as the SSB transmission pattern acquired by the network device.
In some optional embodiments, acquiring the SSB transmission pattern may include: and receiving the SSB transmission pattern transmitted by the network equipment.
In some embodiments, after accessing to the cell to which the base station belongs, the UE may acquire the SSB transmission pattern by receiving a message of the base station, where the message may be an RRC (Radio Resource Control) message or a message from a core network server.
The SSB transmission pattern may be communicated between the base station and the UE through signaling interaction. Here, the signaling may be existing signaling after the UE accesses the cell described in the base station, for example: rrcreatase, RRCsetup; alternatively, it may be a separate signaling, such as: and the SSB pattern transmission, wherein the signaling is sent to the UE by the base station, and the UE returns a confirmation to the base station after receiving the signaling.
In some embodiments, the UE may send the SSB send pattern to the UE by updating the location with the core network, and the core network server may send the SSB send pattern to the UE by including the SSB send pattern field in the identity registration signaling message.
Step 302, adjusting the frequency domain position of the received synchronization signal in 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: and in a preset period, determining the frequency domain position of the received synchronous signal in the target synchronous period according to the SSB sending field corresponding to the target synchronous period in the SSB sending pattern.
In some embodiments, after the UE is powered on for the first time, since no prior information is obtained, cell search, registration, and location update supported by its own capability are performed. After performing registration and location update procedures, the UE obtains from the base station or from the core network server that the SSB of the cell is dynamically transmitted, that is, the frequency domain locations of the SSB blocks of the PSS and the SSS are dynamically changed and transmitted according to the received SSB transmission pattern: in each transmission period, for example, one period is 5 minutes, the sequence of PSS and SSS is not changed, and the frequency domain position of SSB is also kept unchanged. And in the next transmission period, transmitting new PSS and SSS sequences according to the field of the SSB transmission pattern. In a preset period, for example, within 24 hours, the UE always performs the receiving measurement of the PSS and the SSS sequence at the frequency domain position corresponding to the transmission period of the corresponding base station according to the obtained SSB transmission pattern, and then resides in the cell.
With continued reference to fig. 4, an interaction flow 400 of the cell synchronization method of the embodiment of the present application is shown. As shown in FIG. 4, the interaction flow 400 may include the following steps:
in step 401, the network device obtains an SSB transmission pattern.
Step 402, the terminal device obtains an SSB transmission pattern.
Step 403, the network device adjusts the frequency domain position of the transmitted synchronization signal within a preset period according to the SSB transmission pattern.
In 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 contents of the above steps 401 to 404 and the technical effects brought by the same, reference may be made to the related descriptions of steps 201 to 202 and steps 301 to 302 in the corresponding embodiments in fig. 2 and fig. 3, which are not repeated herein.
In the embodiment of the application, because the SSB sending frequency domain position of the base station is dynamically changed, and the strong interference occurring at random does not interfere with the full bandwidth and long time of the frequency domain, even if the strong interference occurs in the current sending period, the UE can quickly receive the PSS and the SSS correctly at another frequency domain position in the next period, thereby ensuring the normal residence of the UE. Meanwhile, the UE has the SSB sending pattern as the prior information, so that the calculation resource loss caused by blind detection or full-band retrieval of the UE is avoided, the time is saved, and the electric energy of the UE is saved.
