The communication interface 22 is used to provide data to the processor 21. The communication interface 22 may be an internal interface of the symbol shutdown device, or may be an external interface of the symbol shutdown device (corresponding to the communication interface 13).

It is noted that the structure shown in fig. 1 (or fig. 2) does not constitute a limitation of the symbol shut-off device, which may include more or less components than those shown in fig. 1 (or fig. 2), or combine some components, or a different arrangement of components, in addition to those shown in fig. 1 (or fig. 2).

The symbol turn-off method provided by the embodiment of the present application is described in detail below with reference to the symbol turn-off device shown in fig. 1 and fig. 2.

As shown in fig. 3, an embodiment of the present application provides a symbol turn-off method, which may be applied to a symbol turn-off device, and may include S301 and S302 described below.

S301, the symbol turn-off device obtains a count value of the first counter when the synchronization signal and the number of SSB beams of the PBCH block sent in the first period are in a normal state.

The first counter may be used to count the number of times that the cell is in a low load state during the periodic load detection.

In a New Radio (NR) communication system of the fifth generation (5 g) communication technology, synchronization signals and physical broadcast channel PBCH (synchronization signal and physical broadcast channel) SSB beams may periodically transmit beams in different directions at different times, thereby realizing coverage of the whole cell. Since the maximum number of SSB beams that can be transmitted by the base station is fixed in each SSB transmission period, the SSB beams being in the normal state means that the number of SSB beams transmitted by the base station in the first period is the maximum number of SSB beams.

Optionally, the SSB may support a default period and a configuration period, where the default period may be 20ms and is used for initial cell search, and the configuration period may be any one of the following: 5ms, 10ms, 20ms, 40ms, 80ms, 160ms. The first period may be a default period or a configuration period.

And S302, if the count value of the first counter is greater than a first threshold value, the symbol turn-off device performs symbol turn-off processing on the time domain position where at least one SSB beam in the SSB beams sent in the second period is located.

The second period is an SSB beam transmission period adjacent to the first period, that is, an SS block burst set period.

It should be noted that the number of the at least one beam is less than or equal to the maximum number of beams transmitted by the symbol turn-off device in a half frame.

It should be noted that the first threshold is a preset value used for defining whether to perform the symbol turn-off process.

Optionally, after performing symbol turn-off processing on the time domain position where at least one SSB beam of the SSB beams sent in the second period is located, the symbol turn-off device may further update the count value of the first counter to 0.

Optionally, since there is no SSB beam width related requirement in the protocol, and the SSB beam design belongs to a base station implementation scheme, the base station may determine the symbol turn-off processing scheme according to its own beam design scheme. Therefore, the at least one SSB beam may be a fixed-direction SSB beam transmitted at the second period; alternatively, the SSB beams transmitted in the second period and in different directions may be used.

Exemplarily, as shown in (a) of fig. 4, the maximum number Lmax =8 of SSB beams transmitted in one half frame is taken as an example. In a conventional SSB transmission manner, SSB beams in one direction are sequentially transmitted in one half frame of a synchronization block burst set period. As shown in fig. 4 (b), the symbol-off process is taken as an example to reduce one SSB beam. The symbol turn-off device may sequentially perform symbol turn-off processing on the time domain positions corresponding to the SSB beams in different directions sent in the second period, that is, when the SS block burst set periodicity T1, the time domain position corresponding to the SSB beam in the first direction is turned off, when the SS block burst set periodicity T2, the time domain position corresponding to the SSB beam in the second direction is turned off, and so on, and when the SS block burst set periodicity T8, the time domain position corresponding to the SSB beam in the eighth direction is turned off. As shown in (c) of fig. 4, the symbol turn-off device may further perform symbol turn-off processing on a time domain position corresponding to the SSB beam in the fixed direction transmitted in the second period. Specifically, the maximum SSB beam number Lmax =7, which includes one broadcast beam and 6 narrow beams, and in the case that N +1 is greater than the first threshold, the symbol turn-off device may fix the transmission of the broadcast beam to ensure the basic coverage in the center of the cell, and the remaining 6 narrow beams are transmitted in turn.

The embodiment of the application provides a symbol turn-off method, which can determine whether to execute symbol turn-off processing on the SSB beams in the second period by judging the count value of the first counter under the condition that the number of the SSB beams sent in the first period is in a normal state, so that the cell coverage requirement can be met within a certain time period, the energy consumption of equipment can be further reduced, and the energy-saving effect of the symbol turn-off technology can be improved.

Optionally, with reference to fig. 3, as shown in fig. 5, before S301, the symbol turn-off method provided in the embodiment of the present application may further include S303, S304a, and S304b described below.

And S303, periodically acquiring the cell load index by the symbol turn-off device.

Optionally, the cell load index may be any one of the following: a Physical Resource Block (PRB) utilization rate, a downlink PRB utilization rate, a Control Channel Element (CCE) utilization rate, and the like.

It should be noted that, in the embodiment of the present application, a period for the symbol turn-off device to obtain the cell load index is not limited, and it can be understood that, in the case of a smaller period, the symbol turn-off device may obtain the cell load index in real time.

S304a, the symbol turn-off device adds 1 to the count value of the first counter when the cell load index is smaller than the first load threshold, and updates the count value of the first counter to 0 when the cell load index is greater than or equal to the first load threshold.

The symbol turn-off device may add 1 to the count value of the first counter, that is, update the count value N of the first counter to N +1, when the cell load index is less than the first load threshold, and update the count value of the first counter to 0, when the cell load index is greater than or equal to the first load threshold. Wherein N is an integer greater than or equal to 0.

The symbol turn-off device can judge whether the cell load index is smaller than the first load threshold, if so, the cell is in a low load state currently. Therefore, the sign off device may update the count value N of the first counter to N +1; if the cell load index is greater than or equal to the first load threshold, the symbol turn-off device may update the count value of the first counter to 0, that is, clear the count value of the first counter, indicating that the low load state is not continued and recounting is required.

It should be noted that the first load threshold may be a preset value used for defining the current load state of the cell.

S304b, the symbol turn-off device adds 1 to the count value of the second counter when the cell load index is greater than the second load threshold, and updates the count value of the second counter to 0 when the cell load index is less than or equal to the second load threshold.

The first load threshold is less than or equal to a second load threshold, and the second counter may be used to count the number of times that the cell is in a high load state in the periodic load detection.

The symbol turn-off device may add 1 to the count value of the second counter, that is, update the count value M of the second counter to M +1, when the cell load index is greater than the second load threshold, and update the count value of the second counter to 0, when the cell load index is less than or equal to the second load threshold. Wherein M is an integer greater than or equal to 0.

The symbol turn-off device may determine whether the cell load indicator is greater than a second load threshold, and if so, it indicates that the cell currently belongs to a high load state. Therefore, the sign off means may update the count value M of the second counter to M +1; if the cell load index is less than or equal to the second load threshold, the symbol shutdown device may update the count value of the second counter to 0, that is, clear the count value of the second counter, indicating that the high load state is no longer continuous and needs to be counted again.

It should be noted that the second load threshold may be a preset value used for defining the current load state of the cell. The second loading threshold is greater than the first loading threshold.

Optionally, with continuing reference to fig. 5, after S303, the symbol turn-off method provided in the embodiment of the present application may further include S305 and S306 described below.

S305, when the number of SSB beams is in the reduced state, the symbol turn-off device obtains a count value of the second counter.

It should be noted that the SSB beam number is in a reduced state, which means that the number of transmitted SSB beams is less than the maximum SSB beam number.

And S306, if the count value of the second counter is greater than the second threshold, the symbol turn-off device restores the number of the SSB beams sent in the third period to a normal state.

The third period may be the second period, that is, if the symbol turn-off device determines that the number of SSB beams in the first period is in the reduced state, instead of the normal state in S301, the symbol turn-off device may return the number of SSB beams transmitted in the second period to the normal state. Alternatively, the third period may be a next SSB beam transmission period adjacent to the second period. That is, after the above S302, the symbol turn-off device may restore the SSB beam number to the normal state.

It should be noted that the second threshold is a preset value for defining whether to perform SSB beam number recovery.

Optionally, after the number of beams transmitted in the second period is recovered to the normal state, the symbol turn-off device may further update the count value of the second counter to 0.

In the embodiment of the present application, since the number of SSB beams transmitted in the third period can be recovered to the normal state under the condition that the number of SSB beams is in the reduced state and the count value of the second counter is greater than the second threshold, it can be ensured that the coverage requirement of the cell can be met after the cell is converted from the low load state to the high load state.
