[0039] It should be understood that all or part of the functions of the communication device in the present application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform such as a cloud platform.

[0040] SSB

[0041] In the NR system, each SSB is used for initial access and synchronization. The SSB consists of three parts: primary synchronization signals (PSS), secondary synchronization signals (SSS), and physical broadcast channel (PBCH). Among them, PSS and SSS are used for time and frequency synchronization, which can help terminal devices find the synchronization information of network devices. PBCH carries basic system information to ensure that the terminal receives higher-layer signals and configurations. SSB is broadcast periodically in the NR system, and the period can be configured to 5ms, 10ms, 20ms, etc. This means that network devices will periodically transmit SSB signals to ensure that new terminal devices can discover and connect to the network. In actual operation, the base station can adjust the transmission power of SSB according to factors such as coverage area and user density. Larger coverage areas may require higher transmission power, which will result in greater power consumption.

[0042] In the NR system, SSB is transmitted in a direction through beamforming. Each beam includes one SSB. The base station can configure multiple beams to cover different directions. The SSBs required to complete a beam scan can form an SSB burst. Generally, the transmission configuration of the SSB burst in time, frequency or space can be described by the SSB burst pattern. For example, Figure 2 The SSB beam scanning and SSB burst set transmission time are shown, where: Figure 2 (a) in FIG. 1 shows the spatial beams for transmitting each SSB. Figure 2 (b) in FIG. 1 shows the time domain position of each SSB. In different frequency bands and configurations, the pattern of the SSB burst may be different. For example, in different frequency bands, the maximum number of SSBs that may be included in an SSB burst may be 4, 8, or 64, etc., and different SSBs have different SSB indexes. Figure 2 It is taken as an example that an SSB burst includes 8 SSB indexes, namely SSB 0 to SSB 7.

[0043] More beams mean more SSB transmissions, which in turn increases power consumption. High-order multiple input multiple output (MIMO) antenna configurations also affect the transmit power and power consumption of SSB. For example, a 64T64R (64 transmit and 64 receive) antenna consumes more power than a lower-order antenna configuration. In an environment where small base stations (e.g., micro base stations and macro base stations) are densely deployed, the coverage area of ​​SSB is smaller and the power consumption is relatively reduced. However, the cumulative power consumption of multiple base stations is still large.

[0044] To this end, an embodiment of the present application provides a method for wireless communication, which configures multiple cycles for SSB transmission for a terminal device through first information, so that SSB transmission is more flexible and can achieve energy saving without affecting SSB performance.

[0045] Combine the following Figure 3 , the embodiments of the present application are introduced in detail.

[0046] Figure 3 A flowchart of a wireless communication method provided in an embodiment of the present application. Figure 3 The method 300 shown can be performed by a terminal device and a network device. The terminal device can be, for example, Figure 1 The terminal device 120 shown in FIG. 1 , the network device may be, for example, Figure 1 The network device 110 shown in FIG.

[0047] See also Figure 3 , in step 310, the network device sends first information to the terminal device.

[0048] Correspondingly, in step 320, the terminal device receives the first information sent by the network device.

[0049] Among them, the first information indicates multiple periodic configurations for SSB transmission, or the first information indicates multiple periodic configurations for receiving SSB. In the embodiment of the present application, the received SSB can also be replaced by a measurement SSB or a detection SSB. The SSB described in the embodiment of the present application can be a value SSB burst, or one or more SSB indexes in an SSB burst.

[0050] In the embodiment of the present application, SSB transmission can have multiple cycles. For example, when the network load is busy, it can be switched to a shorter cycle for SSB transmission; when the network load is light, it can be switched to a longer cycle for SSB transmission. In this way, SSB transmission is more flexible and can achieve energy saving without affecting SSB performance.

[0051] Each of the multiple cycle configurations may include one or more cycles. As an example, each cycle configuration includes one cycle, assuming that cycle configuration 1 includes cycle T1, cycle configuration 2 includes cycle T2, cycle T1 may be a longer cycle, and cycle T2 may be a shorter cycle. For another example, each cycle configuration includes multiple cycles, assuming that cycle configuration 1 includes cycle T11 and cycle T12, wherein cycle T11 may be a longer cycle, cycle T12 may be a shorter cycle, and cycle configuration 2 includes cycle T21 and cycle T22, wherein cycle T21 may be a longer cycle, and cycle T22 may be a shorter cycle.

[0052] In some implementations, different period configurations include periods with an integer multiple relationship; and / or, the same period configuration includes periods with an integer multiple relationship. As an example, the period that may be used to transmit SSB may be a period with an integer multiple relationship such as 20 milliseconds, 40 milliseconds, 60 milliseconds, 80 milliseconds, 160 milliseconds, etc. For example, the above-mentioned period T1 and period T2 belonging to different period configurations have an integer multiple relationship, and period T1 may be an integer multiple of period T2, for example, period T1 is 160 milliseconds, period T2 is 20 milliseconds, or period T1 is 120 milliseconds, and period T2 is 40 milliseconds. For another example, the above-mentioned period T11 and period T12 belonging to the same period configuration may have an integer multiple relationship, and period T11 may be an integer multiple of period T12, for example, period T11 is 160 milliseconds, period T12 is 20 milliseconds, or period T11 is 120 milliseconds, and period T12 is 40 milliseconds. For another example, the period T21 and period T22 belonging to the same period configuration may have an integer multiple relationship, and the period T21 may be an integer multiple of the period T22, for example, the period T21 is 160 milliseconds and the period T22 is 20 milliseconds, or the period T21 is 120 milliseconds and the period T22 is 40 milliseconds.

[0053] In some implementations, the multiple period configurations may be associated with different SSB bursts (e.g., SSB bursts transmitted at different times); or, the multiple period configurations may be associated with different SSB index groups (e.g., different index groups in an SSB burst). The SSB index group may include one SSB index, or may include multiple SSB indexes. The periods in the period configurations associated with different SSB index groups may be the same, in which case it may be considered that the multiple period configurations are associated with these SSB index groups to form an SSB burst; or, the period configurations associated with different SSB index groups may be different, for example, the periods included in the period configurations associated with different SSB index groups may be completely different or partially different. As an example, multiple period configurations in the first information are associated with different SSB index groups, and the multiple configurations include period configuration 1 and period configuration 2, wherein period configuration 1 is used to transmit SSB index group 1, and period configuration 2 is used to transmit SSB index group 2, period configuration 1 may include one or more periods for transmitting SSB index group 1, and period configuration 2 may include one or more periods for transmitting SSB index group 2, and the SSB indexes included in SSB index group 1 and SSB index group 2 may be partially or completely different. In addition, the number of SSB indexes included in SSB index group 1 and SSB index group 2 may be the same or different.

[0054] SSB transmission uses beam scanning. In different beam directions, the service measurement delay required by the terminal device may be different. For example, in some directions, the terminal device has strong mobility, and the terminal devices in these directions need to perform SSB measurements frequently. Or, in the case where some vehicle-mounted services require faster inter-cell switching, the terminal device also needs to perform SSB measurements faster. For example, some beams of the base station cover highways, while some beams cover ordinary roads and farmland in the cell. The SSB covering the direction of the highway should have a shorter measurement period than the SSB covering the direction of ordinary roads and farmland in the cell. Therefore, associating the SSB transmission period with the SSB index ensures the detection performance of the SSB in certain directions and saves the power consumption caused by SSB transmission in other directions.

[0055] As an example, Figure 4The topology between the terminal device and the base station shown in the figure, wherein the SSB burst includes 8 SSB indexes, namely SSB 0, SSB 1, SSB 2, SSB 3, SSB 4, SSB 5, SSB 6 and SSB 7. Among them, SSB 0, SSB 1, SSB 2 and SSB 3 belong to SSB index group 1, and SSB 4, SSB 5, SSB 6 and SSB7 belong to SSB index group 2. It is assumed that in the area covered by SSB 4, SSB 5, SSB 6 and SSB7 in index group 2, the terminal device needs to perform faster cell switching and faster SSB measurement, while in the area covered by SSB 0, SSB 1, SSB 2 and SSB 3 in index group 1, the terminal device does not need to perform frequent SSB measurements. Therefore, index group 1 can be associated with a longer period, and index group 2 can be associated with a shorter SSB period. The network device may notify the terminal device of the period configuration 1 associated with SSB index group 1 and the period configuration 2 associated with SSB index group 2 through the first information. For example, period configuration 1 includes SSB 0, SSB 1, SSB 2 and SSB 3, and the corresponding period T1, and period configuration 2 includes SSB 4, SSB 5, SSB 6 and SSB7, and the corresponding period T2. T1 may be greater than T2, for example, T1 may be an integer multiple of T2. Each SSB burst sent by the network device may include some SSB indexes from SSB 0 to SSB 7, wherein, for the SSB indexes belonging to index group 1, the terminal device may perform corresponding SSB measurements based on the period T1 in period configuration 1, and for the SSB indexes belonging to index group 2, the terminal device may perform corresponding SSB measurements based on the period T2 in period configuration 1.

[0056] In some implementations, the first information is sent during a cell configuration process of a terminal device, and the cell configuration includes one or more of the following: cell access, cell switching, and adding a secondary cell. That is, when configuring a new cell for a terminal device, the first information may indicate a plurality of periods for SSB transmission, and the new cell may be a new cell (or a target cell) during a cell access, cell switching, or adding a secondary cell.

[0057] The first information may be carried in, for example, radio resource control (RRC) signaling, broadcast signaling, multicast signaling, or system information.

[0058] In some implementations, the multiple periods are associated with the terminal device. That is, the multiple periods configured for different terminal devices may be different, for example, partially or completely different. In this case, the first information may be carried by RRC signaling. If the multiple periods are not associated with the terminal device, the same multiple periods are configured for all terminal devices in the cell or group. In this case, the first information may be carried by multicast signaling or broadcast signaling, and the first information sent by the network device is applicable to all terminal devices in the cell or group.

[0059] In some implementations, the period for receiving SSB is the same as the period for sending SSB by the network device; or, the period for receiving SSB is an integer multiple of the period for sending SSB by the network device. That is, the period used by the network device to send SSB may be the same as or different from the period used by the terminal device to receive SSB (for example, an integer multiple). As an example, suppose the network device sends SSB at a period of 40ms, but the network device notifies the terminal device that multiple periods for receiving SSB include 80ms and 160ms. The terminal device needs to measure SSB at 80ms and 160ms, and does not need to measure SSB at a period of 40ms when the network device actually sends SSB. At this time, although the power consumption of the network device is still the power consumption caused by the 40ms period of SSB transmission, from the perspective of the terminal device, its power consumption is saved.

[0060] In some implementations, the first information may also be used to indicate the number of cycles of continuous reception of the SSB, that is, to indicate how many cycles of SSB the terminal device continuously receives.

[0061] In some implementations, such as Figure 5 As shown, method 300 may further include step 330 and step 340 .

[0062] In step 330, the network device sends second information to the terminal device.

[0063] Correspondingly, in step 340, the terminal device receives the second information sent by the network device.

[0064] Among them, the second information is used to indicate the target cycle that is activated among the multiple cycles (that is, the cycle used by the SSB that is currently being or to be transmitted). Optionally, the multiple cycles may be cycles in different cycle configurations, or different cycles in the same cycle configuration. In other words, the multiple cycles belong to different cycle configurations (for example, different cycle configurations associated with SSB bursts), or belong to the same cycle configuration (for example, a cycle configuration associated with a certain SSB index). As an example, in a case where the multiple cycle configurations indicated by the first information are associated with different SSB bursts and each cycle configuration includes one cycle, the target cycle may be a cycle in the cycle configuration that is activated among the multiple cycle configurations; for another example, in a case where the multiple cycle configurations indicated by the first information are associated with different SSB indexes and each cycle configuration includes multiple cycles, the target cycle may be an activated cycle among the multiple cycles included in the cycle configuration associated with a certain SSB index.

[0065] In some implementations, the second information is sent during a cell configuration process of the terminal device, and the cell configuration includes one or more of the following: cell access, cell switching, and adding a secondary cell. That is, when configuring a new cell for the terminal device, the second information may indicate a target period currently activated in the multiple periods, and the new cell may be, for example, a new cell (or a target cell) during a cell access, cell switching, or adding a secondary cell.

[0066] As an example, assuming that the multiple cycles are associated with different SSB bursts, the terminal device receives first information sent by the network device, the first information indicating multiple cycle configurations configured by the network device for the terminal device to receive SSB bursts, and the terminal device receives second information sent by the network device, the second information indicating a cycle in the activated cycle configuration among the multiple cycle configurations (i.e., the target cycle).

[0067] The target period may be associated with the terminal device, that is, the target period corresponding to different terminal devices may be different. In this case, the network device may indicate the target period used by the currently actually transmitted SSB through high-level signaling. Alternatively, the target period may not be associated with the terminal device, that is, the target period corresponding to different terminal devices may be the same, and the target period is applicable to all terminal devices in the cell or group. In this case, the network device may indicate the target period used by the currently actually transmitted SSB through broadcast signaling or multicast signaling.

[0068] In some implementations, such as Figure 6 As shown, method 300 may further include step 350 and step 360 .

[0069] In step 350, the network device sends third information to the terminal device.

[0070] Correspondingly, in step 360, the terminal device receives the third information sent by the network device.

[0071] Among them, the third information is used to indicate the adjustment of the period for receiving SSB. In other words, the third information is information indicating period switching. For example, the third information can carry a medium access control control element (MAC CE) or physical layer signaling. Optionally, the adjusted period and the period before adjustment can be periods in different period configurations, or different periods in the same period configuration. In other words, the adjusted period and the period before adjustment belong to different period configurations (for example, different period configurations associated with SSB bursts), or belong to the same period configuration (for example, a period configuration associated with a certain SSB index). As an example, in a case where the multiple period configurations indicated by the first information are associated with different SSB bursts and each period configuration includes one period, the adjusted period and the period before the adjustment belong to different period configurations among the multiple period configurations, that is, the period adjustment is performed for the SSB burst, such as the periods used to receive the SSB burst before and after the adjustment are different; for another example, in a case where the multiple period configurations indicated by the first information are associated with different SSB indexes and each period configuration includes multiple periods, the adjusted period and the period before the adjustment may belong to different periods in the period configuration associated with a certain SSB index, that is, the period adjustment is performed for the SSB index, such as the periods used to receive the SSB with the SSB index before and after the adjustment are different.

[0072] At this time, the network device will send SSB based on the switched period, and correspondingly, the terminal device will also receive SSB using the switched period based on the third information. The third information may also carry information about the switched period.

[0073] In some implementations, the terminal device receives SSB based on the adjusted period from the first moment after receiving the third information. When the network device notifies the terminal device to switch the period through the third information, the terminal device can immediately switch the period to receive SSB, or, after a period of time after receiving the third information, receive SSB according to the switched period (or new period).

[0074] In some implementations, the first moment may include the following:

[0075] 1) The time interval between the first moment and the third information is pre-agreed;

[0076] 2) The time interval between the first moment and the third information is equal to the adjusted period;

[0077] 3) The time interval between the first moment and the last SSB transmitted before the third information is equal to the adjusted period;

[0078] 4) the time interval between the first moment and the first SSB transmitted after the third information is equal to the adjusted period;

[0079] 5) the first time is located after the first time interval from the third information, and the time interval between the first time and the last SSB transmitted before the end time of the first time interval is equal to an integer multiple of the adjusted period;

[0080] 6) The first moment is the first moment after the third information among multiple periodic candidate moments, and the period of the multiple candidate moments is the adjusted period.

[0081] It should be noted that, before the first moment, the transmission of SSB is based on the period before adjustment (or the original period or the old period). For the first case, SSB can be received based on the adjusted period after a preset time has passed since the third information was received. That is to say, the first moment can be the end moment of the preset time, and the preset time can be pre-agreed, or the preset time can be equal to the adjusted period, i.e., the second case.

[0082] The difference between the third case and the fourth case is that after the network device sends the third information, it sends the SSB directly based on the adjusted period, or first sends an SSB based on the period before the adjustment, and then sends the SSB based on the adjusted period. If the network device sends the SSB directly based on the adjusted period after sending the third information, the time interval between the first moment and the last SSB transmitted before the third information is equal to the adjusted period, that is, the time interval between the first SSB transmitted after the third information and the last SSB transmitted before the third information is equal to the adjusted period. If the network device still needs to send another SSB based on the period before the adjustment after sending the third information, the time interval between the first moment and the last SSB transmitted after the third information is equal to the adjusted period. Accordingly, after receiving the third information, the terminal device needs to receive an SSB based on the period before the adjustment, and then receive the following SSB based on the adjusted period, that is, the interval between the first SSB transmitted after the third information and the second SSB is equal to the adjusted period.

[0083] In case 5), the condition of setting the first time interval is that the first moment needs to be after the first time interval, and the time interval between the first moment and the last SSB transmitted before the end moment of the first time interval is equal to an integer multiple of the adjusted period.

[0084] In case 6), the positions of multiple candidate time points based on the adjusted period distribution are determined, and after receiving the third information, the terminal device searches for the candidate time point closest to the third information as the first time point, and receives the SSB based on the adjusted period from the first time point. As an example, Figure 7 As shown, it is assumed that the time when the terminal device receives the third information is T0, and the period before adjustment is T A , the adjusted period is T B , then the period of multiple candidate moments is T B , the first moment is the first candidate moment after the moment T0.

[0085] Optionally, the positions of the multiple candidate moments are determined based on the position of a reference moment among the multiple candidate moments, and the reference moment is, for example, pre-agreed or indicated by a network device. As an example, the reference moment may be the position of the first SSB among the multiple candidate positions, and the terminal device obtains the position of the first SSB, such as the time slot position corresponding to the first SSB, and then determines the positions of other SSBs among the multiple candidate moments based on the position of the first SSB and the adjusted period.

[0086] In some implementations, a second time interval may be set after the third information, and the position of the first moment may be determined based on whether there is SSB transmission in the second time interval. For example, in the case where there is SSB transmission in the second time interval from the third information, the time interval between the first moment and the last SSB transmitted in the second time interval is equal to an integer multiple of the adjusted period, and the first moment may be, for example, the first moment after the second time interval that satisfies the integer multiple relationship. For another example, in the case where there is no SSB transmission in the first time interval, the first moment is the end moment of the second time interval, or the first moment is located after the end moment of the first time interval, and the time interval between the first moment and the last SSB transmitted before the second time interval is equal to an integer multiple of the adjusted period, and the first moment is the first moment after the second time interval that satisfies the integer multiple relationship.

[0087] As an example, assume that the time when the terminal device receives the third information is T0, and the period before adjustment is T A , the adjusted period is T B , the second time interval is △T2. Figure 8 As shown, if there is SSB transmission within △T2, the time interval between the first moment and the SSB within △T2 is T B .like Fig. 9 As shown in Figure 2, if there is no SSB transmission within △T2, the time interval between the first moment and the last SSB before △T2 is T BThe first moment is the first moment that meets the above requirements after the end of △T2. Fig.11 The time interval between the first moment and the last SSB received before △T2 is T B Take twice as much as an example.

[0088] In some implementations, the position of the first moment can be determined based on the size relationship between the period before adjustment and the period after adjustment. For example, when the adjusted period is smaller than the period before adjustment, the time interval between the first moment and the last SSB transmitted before the third information is equal to an integer multiple of the adjusted period, and the first moment is the first moment after the third information that satisfies the integer multiple relationship. For another example, when the adjusted period is larger than the period before adjustment, the first moment is located after the second time interval from the third information, and the time interval between the first moment and the last SSB received before the end of the second time interval is equal to an integer multiple of the adjusted period, and the first moment is the first moment after the second time interval that satisfies the integer multiple relationship.

[0089] As an example, assume that the time when the terminal device receives the third information is T0, and the period before adjustment is T A , the adjusted period is T B , the third time interval is △T3. Fig.10 As shown in FIG. 1 , if the adjusted period is smaller than the period before adjustment, it indicates that the measurement demand for low-latency SSB becomes larger, and the measurement period of SSB needs to be adjusted as soon as possible. Therefore, the time interval between the first moment and the last SSB transmitted before the third information is equal to T B In fact, starting from the previous SSB transmission, SSB transmission has been carried out based on a shorter new cycle. Fig.11 As shown, if the adjusted period is greater than the period before adjustment, the time interval between the first moment after △T3 and the last SSB received before the end time of △T3 is T B , and the first moment is the first moment that meets the above requirements after the end of △T3, Fig.11 The time interval between the first moment and the last SSB received before the end of △T3 is T B Take twice as much as an example.

[0090] In other implementations, the time when the third information is correctly decoded may also be considered to avoid the problem of inconsistent understanding of the SSB between the terminal device and the network device. For example, the first moment is after the second moment, and the time interval between the first moment and the last received SSB before the second moment is an integer multiple of the adjusted period. The second moment may be the moment when it is determined that the third information is correctly decoded. For example, the third information may be the moment when ACK information for the third information is sent or received.

[0091] In some implementations, the multiple period configurations indicated by the first information are associated with discontinuous transmission (DTX) of the cell. For example, the activation time corresponding to DTX corresponds to the first period configuration, the inactive time corresponding to DTX corresponds to the second period configuration, the first period configuration includes the first period, and the second period configuration includes the second period. Then, the first period may be smaller than the second period. In other words, SSB transmission is performed based on a longer period during the inactive period corresponding to DTX, and SSB transmission is performed based on a shorter period during the active time corresponding to DTX. Taking into account the measurement requirements of the activation time, the time starting point of the SSB transmission of the shorter period may be earlier than the time starting point of the activation time.
