For example, the terminal device can act as a scheduling entity, providing sidelink signals between terminal devices in vehicle-to-everything (V2X) or device-to-device (D2D) systems. For instance, cellular phones and cars communicate with each other using sidelink signals. Cellular phones and smart home devices communicate without relaying communication signals through base stations.

[0036] In this embodiment, the network device can be a device used to communicate with terminal devices. The network device can be, for example, an access network device or a wireless access network device. For instance, the network device can be a base station. The term "base station" can broadly encompass various names as follows, or can be replaced by names such as: NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), master station (MeNB), secondary station SeNB (SeNB), multi-mode wireless (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, micro base station, relay node, donor node, or a combination thereof.

Base stations can support networks using the same or different access technologies. The embodiments of this application do not limit the specific technologies or equipment forms used in the network equipment.

[0037] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move depending on the location of the mobile base station. In other examples, a helicopter or drone can be configured as a device to communicate with another base station.

[0040] It should be understood that all or part of the functions of the communication device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform such as a cloud platform.

[0041] SSB

[0042] In NR systems, each SSB (Secondary Synchronization Signal) is used for initial access and synchronization. An SSB consists of three parts: primary synchronization signals (PSS), secondary synchronization signals (SSS), and a physical broadcast channel (PBCH). The PSS and SSS are used for time-frequency synchronization, helping terminal devices find synchronization information from network devices. The PBCH carries basic system information, ensuring that the terminal receives higher-level signals and configurations. SSBs are broadcast periodically in NR systems, with periods configurable to 5ms, 10ms, 20ms, etc. This means that network devices periodically transmit SSB signals, ensuring that new terminal devices can discover and connect to the network. In practice, base stations can adjust the SSB transmission power based on factors such as coverage area and user density. Larger coverage areas may require higher transmission power, which leads to greater power consumption.

[0043] In NR systems, SSBs are transmitted directionally via beamforming. Each beam includes one SSB, and base stations can configure multiple beams to cover different directions. The SSBs required to complete one beam scan can form an SSB burst. Typically, the transmission configuration of an SSB burst in time, frequency, or spatial domain can be described by the pattern of the SSB burst. For example, Figure 2 shows the SSB beam scan and the transmission times of the SSB burst set. In Figure 2(a), the spatial beam transmitting each SSB is shown, and in Figure 2(b), the temporal location of each SSB is shown. The pattern of the SSB burst may differ under different frequency bands and configurations. For example, in different frequency bands, an SSB burst may include up to 4, 8, or 64 SSBs, etc., and different SSBs have different SSB indices. Figure 2 uses an SSB burst including 8 SSB indices, namely SSB 0 to SSB 7, as an example.

[0044] More beams mean more SSBs (Special Signal-Based Buses) transmitting, thus increasing power consumption. Higher-order multiple-input multiple-output (MIMO) antenna configurations also affect SSB transmit power and power consumption. For example, a 64T64R (64 transmit, 64 receive) antenna consumes more power than a lower-order antenna configuration. In environments with dense deployment of small base stations (e.g., micro base stations, macro base stations), the coverage area of ​​SSBs is smaller, resulting in relatively lower power consumption. However, the cumulative power consumption of multiple base stations is still significant.

[0045] Therefore, embodiments of this application provide a wireless communication method that configures multiple cycles for SSB transmission for a terminal device using first information, making SSB transmission more flexible and enabling energy saving without affecting SSB performance.

[0046] The embodiments of this application will be described in detail below with reference to Figure 3.

[0047] Figure 3 is a schematic flowchart of a wireless communication method provided in an embodiment of this application. The method 300 shown in Figure 3 can be executed by a terminal device and a network device. The terminal device can be, for example, the terminal device 120 shown in Figure 1, and the network device can be, for example, the network device 110 shown in Figure 1.

[0048] Referring to Figure 3, in step 310, the network device sends the first information to the terminal device.

[0049] Accordingly, in step 320, the terminal device receives the first information sent by the network device.

[0050] The first information indicates multiple periodic configurations for SSB transmission, or in other words, the first information indicates multiple periodic configurations for receiving SSBs. In this embodiment, the received SSB can also be replaced by a measured SSB or a detected SSB. The SSB in this embodiment can be a value SSB burst, or one or more SSB indices from a to SSB burst.

[0051] In this embodiment, SSB transmission can have multiple cycles. For example, when the network load is high, it can switch to a shorter cycle for SSB transmission; when the network load is low, it can switch to a longer cycle for SSB transmission. This makes SSB transmission more flexible and enables energy saving without affecting SSB performance.

[0052] Each of these multiple cycle configurations may include one or more cycles. As an example, each cycle configuration may include one cycle. Suppose cycle configuration 1 includes cycle T1, cycle configuration 2 includes cycle T2, where cycle T1 can be a longer cycle and cycle T2 can be a shorter cycle. Alternatively, each cycle configuration may include multiple cycles. Suppose cycle configuration 1 includes cycles T11 and T12, where cycle T11 can be a longer cycle and cycle T12 can be a shorter cycle, and cycle configuration 2 includes cycles T21 and T22, where cycle T21 can be a longer cycle and cycle T22 can be a shorter cycle.

[0053] In some implementations, different period configurations include periods that are multiples of each other; and / or, the same period configuration includes periods that are multiples of each other. As an example, the period used to transmit SSBs may be 20 milliseconds, 40 milliseconds, 60 milliseconds, 80 milliseconds, 160 milliseconds, etc., periods that are multiples of each other. For example, if periods T1 and T2 belonging to different period configurations are multiples of each other, period T1 can be an integer multiple of period T2, such as period T1 being 160 milliseconds and period T2 being 20 milliseconds, or period T1 being 120 milliseconds and period T2 being 40 milliseconds. As another example, if periods T11 and T12 belonging to the same period configuration are multiples of each other, period T11 can be an integer multiple of period T12, such as period T11 being 160 milliseconds and period T12 being 20 milliseconds, or period T11 being 120 milliseconds and period T12 being 40 milliseconds. For example, the periods T21 and T22, which belong to the same period configuration, can be integer multiples of each other. The period T21 can 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.

[0054] In some implementations, the multiple period configurations can be associated with different SSB bursts (e.g., SSB bursts transmitted at different times); or, the multiple period configurations can be associated with different SSB index groups (e.g., different index groups within an SSB burst). Each SSB index group may include one SSB index or multiple SSB indexes. The periods in the period configurations associated with different SSB index groups can be the same; in this case, the multiple period configurations associated with these SSB index groups can be considered to form an SSB burst. Alternatively, the period configurations associated with different SSB index groups can be different; for example, the periods included in the period configurations associated with different SSB index groups may be all different or partially different. As an example, the multiple periodic configurations in the first information are associated with different SSB index groups. These multiple configurations include periodic configuration 1 and periodic configuration 2. Periodic configuration 1 is used to transmit SSB index group 1, and periodic configuration 2 is used to transmit SSB index group 2. Periodic configuration 1 may include one or more periods for transmitting SSB index group 1, and periodic configuration 2 may include one or more periods for transmitting SSB index group 2. 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.

[0055] SSB transmission employs beam scanning. The latency required for service measurements by terminal devices may differ depending on the beam direction. For example, in some directions, terminal devices are highly mobile and require frequent SSB measurements. Alternatively, in some vehicular services requiring rapid inter-cell handover, terminal devices also need to perform SSB measurements quickly. For instance, some base station beams cover highways, while others cover ordinary roads or farmland within the cell. SSBs covering highways should have shorter measurement cycles compared to SSBs covering ordinary roads or farmland. Therefore, correlating the SSB transmission cycle with the SSB index ensures SSB detection performance in certain directions while saving power consumption caused by SSB transmission in other directions.

[0056] As an example, Figure 4 shows the topology between the terminal device and the base station. The SSB burst includes eight SSB indices: SSB 0, SSB 1, SSB 2, SSB 3, SSB 4, SSB 5, SSB 6, and SSB 7. SSB 0, SSB 1, SSB 2, and SSB 3 belong to SSB index group 1, while SSB 4, SSB 5, SSB 6, and SSB 7 belong to SSB index group 2. Assume that within the area covered by SSB 4, SSB 5, SSB 6, and SSB 7 in index group 2, the terminal device needs to perform faster cell handovers and conduct SSB measurements more frequently. However, within 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 longer periods, while index group 2 can be associated with shorter SSB periods. The network device can 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; period configuration 2 includes SSB 4, SSB 5, SSB 6, and SSB 7 and the corresponding period T2. T1 can be greater than T2; for example, T1 can be an integer multiple of T2. Each SSB burst sent by the network device may include some SSB indices from SSB 0 to SSB 7. For SSB indices belonging to index group 1, the terminal device can perform corresponding SSB measurements based on period T1 in period configuration 1; for SSB indices belonging to index group 2, the terminal device can perform corresponding SSB measurements based on period T2 in period configuration 1.

[0057] In some implementations, the first information is sent during the cell configuration process of the terminal device. This cell configuration includes one or more of the following: cell access, cell handover, and adding a secondary cell. That is, when configuring a new cell for the terminal device, the first information can indicate multiple cycles for SSB transmission. This new cell can be a new cell (or target cell) during the cell access, cell handover, or adding a secondary cell process.

[0058] The first piece of information can be carried in radio resource control (RRC) signaling, broadcast signaling, multicast signaling, or system information.

[0059] In some implementations, these multiple cycles are associated with terminal devices. That is, the multiple cycles configured for different terminal devices can be different, for example, partially or completely different. In this case, the first information can be carried through RRC signaling. If the multiple cycles are not associated with terminal devices, then the same multiple cycles are configured for all terminal devices within the cell or group. In this case, the first information can be carried through multicast signaling or broadcast signaling, and the first information sent by the network device is applicable to all terminal devices within the cell or group.

[0060] In some implementations, the period used to receive SSBs is the same as the period used by the network device to send SSBs; or, the period used to receive SSBs is an integer multiple of the period used by the network device to send SSBs. That is, the period used by the network device to send SSBs can be the same as or different from the period used by the terminal device to receive SSBs (e.g., they can be integer multiples of each other). For example, suppose the network device sends SSBs at a period of 40ms, but the network device informs the terminal device that multiple periods for receiving SSBs include 80ms and 160ms. The terminal device needs to measure the SSBs according to the 80ms and 160ms periods, and does not need to measure the SSBs according to the actual 40ms period used by the network device. In this case, although the power consumption of the network device is still the power consumption caused by the 40ms period SSB transmission, from the perspective of the terminal device, it saves its power consumption.

[0061] In some implementations, the first information can also be used to indicate the number of consecutive SSB cycles received. That is, it indicates how many consecutive SSB cycles the terminal device receives.

[0062] In some implementations, as shown in Figure 5, method 300 may also include steps 330 and 340.

[0063] In step 330, the network device sends the second information to the terminal device.

[0064] Accordingly, in step 340, the terminal device receives the second information sent by the network device.

[0065] The second information indicates the target period (i.e., the period currently being transmitted or to be transmitted by the SSB) that is active among multiple periods. Optionally, these multiple periods can be periods in different period configurations, or different periods in the same period configuration. Alternatively, the multiple periods may belong to different period configurations (e.g., different period configurations associated with an SSB burst), or belong to the same period configuration (e.g., a period configuration associated with a certain SSB index). As an example, if the multiple period configurations indicated by the first information are associated with different SSB bursts and each period configuration includes one period, the target period can be a period in the active period configuration among the multiple period configurations; or, for example, if the multiple period configurations indicated by the first information are associated with different SSB indexes and each period configuration includes multiple periods, the target period can be a period active among the multiple periods included in the period configuration associated with a certain SSB index.

[0066] In some implementations, the second information is sent during the cell configuration process of the terminal device. This cell configuration includes one or more of the following: cell access, cell handover, and adding a secondary cell. That is, when configuring a new cell for the terminal device, the second information can indicate the target period currently active among these multiple periods. This new cell can be, for example, a new cell (or target cell) during the process of cell access, cell handover, or adding a secondary cell.

[0067] As an example, assuming that the multiple periods are associated with different SSB bursts, the terminal device receives first information sent by the network device, the first information indicating that the network device has configured multiple period configurations for receiving SSB bursts for the terminal device, and the terminal device receives second information sent by the network device, the second information indicating the period (i.e., the target period) in the activated period configuration among the multiple period configurations.

[0068] The target period can be associated with the terminal device, meaning different terminal devices can have different target periods. In this case, the network device can indicate the target period used by the currently transmitted SSB through higher-layer signaling. Alternatively, the target period can be independent of the terminal device, meaning different terminal devices can have the same target period. This target period applies to all terminal devices within the cell or group. In this case, the network device can indicate the target period used by the currently transmitted SSB through broadcast signaling or multicast signaling.

[0069] In some implementations, as shown in Figure 6, method 300 may also include steps 350 and 360.

[0070] In step 350, the network device sends third information to the terminal device.

[0071] Accordingly, in step 360, the terminal device receives the third information sent by the network device.

[0072] The third information is used to indicate the adjustment of the period used to receive SSBs. In other words, the third information indicates a period switching. For example, the third information can carry medium access control (MAC) control element (CE) or physical layer signaling. Optionally, the adjusted period and the original period can be periods in different period configurations, or different periods in the same period configuration. Alternatively, the adjusted period and the original period belong to different period configurations (e.g., different period configurations associated with SSB bursts), or belong to the same period configuration (e.g., period configurations associated with a specific SSB index). As an example, when 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 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 period used to receive the SSB burst is different before and after the adjustment; as another example, when the multiple period configurations indicated by the first information are associated with different SSB indices and each period configuration includes multiple periods, the adjusted period and the period before adjustment may belong to different periods among the period configurations associated with a certain SSB index, that is, the period adjustment is performed for that SSB index, such as the period used to receive SSBs with that SSB index is different before and after the adjustment.

[0073] At this point, the network device will send an SSB based on the new handover period, and correspondingly, the terminal device will also receive the SSB based on the new handover period using the third information. This third information may also carry information about the new handover period.

[0074] In some implementations, the terminal device receives SSBs based on the adjusted period from the moment it receives the third information. When the network device notifies the terminal device to switch periods via the third information, the terminal device can immediately switch periods to receive SSBs, or it can receive SSBs according to the switched period (or new period) some time after receiving the third information.

[0075] In some implementations, the first moment can include the following:

[0076] 1) The time interval between the first moment and the third piece of information is pre-agreed upon;

[0077] 2) The time interval between the first moment and the third information is equal to the adjusted period;

[0078] 3) The time interval between the first moment and the last SSB transmitted before the third information is equal to the adjusted period;

[0079] 4) The time interval between the first moment and the first SSB transmitted after the third information is equal to the adjusted period;

[0080] 5) The first moment is located after the first time interval starting from the third information, and the time interval between the first moment and the last SSB transmitted before the end of the first time interval is equal to an integer multiple of the adjusted period.

[0081] 6) The first moment is the first moment after the third information among multiple candidate moments in a periodic pattern, and the period of the multiple candidate moments is the adjusted period.

[0082] 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 case 1), SSB can be received based on the adjusted period after a preset time has elapsed since the third information was received. That is to say, the first moment can be the end time of the preset time, which can be pre-agreed or equal to the adjusted period, i.e., case 2).

[0083] The difference between scenarios 3) and 4) lies in whether the network device, after sending the third information, directly sends an SSB based on the adjusted period, or first sends an SSB based on the original period and then sends another SSB based on the adjusted period. If the network device directly sends an SSB 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. In other words, 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 an SSB based on the original period 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. Correspondingly, after receiving the third information, the terminal device needs to receive an SSB based on the original period and then receive the subsequent SSBs based on the adjusted period. In other words, the interval between the first and second SSBs transmitted after the third information is equal to the adjusted period.

[0084] In case 5), the condition for the first time interval is set that the first moment must be after the first time interval, and the time interval between the first moment and the last SSB transmitted before the end of the first time interval is equal to an integer multiple of the adjusted period.

[0085] In case 6), the positions of multiple candidate moments based on the adjusted periodic distribution are determined. After receiving the third information, the terminal device finds the candidate moment closest to the third information as the first moment, and receives the SSB based on the adjusted period starting from the first moment. As an example, as shown in Figure 7, assume that the terminal device receives the third information at moment T0, and the period before adjustment is T. A The adjusted period is T. B Then the period of multiple candidate times is T. B The first time point is the first candidate time point after time point T0.

[0086] Optionally, the positions of the multiple candidate times are determined based on the position of a reference time among the multiple candidate times. This reference time may be pre-agreed or indicated by the network device. As an example, the reference time may be the position of the first SSB among the multiple candidate positions. 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 the other SSBs among the multiple candidate times based on the position of the first SSB and the adjusted period.

[0087] In some implementations, a second time interval can be set after the third message, and the position of the first moment can be determined based on whether an SSB is transmitted within the second time interval. For example, if an SSB is transmitted within the second time interval starting from the third message, the time interval between the first moment and the last SSB transmitted within the second time interval is an integer multiple of the adjusted period. The first moment could be, for example, the first moment after the second time interval that satisfies this integer multiple relationship. Alternatively, if no SSB is transmitted within the first time interval, the first moment can be the end of the second time interval, or the first moment can be located after the end of the first time interval, and the time interval between it and the last SSB transmitted before the second time interval is an integer multiple of the adjusted period, and the first moment can be the first moment after the second time interval that satisfies this integer multiple relationship.

[0088] As an example, assume the terminal device receives the third information at time T0, and the period before adjustment is T. A The adjusted period is T. B The second time interval is ΔT2. As shown in Figure 8, if an SSB is transmitted within ΔT2, then the time interval between the first moment and the SSB within ΔT2 is T. B As shown in Figure 9, if there is no SSB transmission within ΔT2, then the time interval between the first moment and the last SSB before ΔT2 is T. BThe time interval T is an integer multiple of ΔT2, and the first time point is the first time point after ΔT2 that meets the above requirements. Figure 11 shows the time interval T between the first time point and the last SSB received before ΔT2. B For example, twice the amount of [the product / service].

[0089] In some implementations, the position of the first moment can be determined based on the relationship between the period before and after adjustment. For example, if the adjusted period is shorter than the period before adjustment, the time interval between the first moment and the last SSB transmitted before the third information is an integer multiple of the adjusted period, and the first moment is the first moment after the third information that satisfies this integer multiple relationship. As another example, if the adjusted period is longer than the period before adjustment, the first moment is located after the second time interval starting 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 an integer multiple of the adjusted period, and the first moment is the first moment after the second time interval that satisfies this integer multiple relationship.

[0090] As an example, assume the terminal device receives the third information at time T0, and the period before adjustment is T. A The adjusted period is T. B The third time interval is ΔT3. As shown in Figure 10, if the adjusted period is smaller than the original period, it indicates that the demand for low-latency SSB measurement has increased, and the SSB measurement period 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 previously transmitted SSB, SSB transmission is already based on a shorter new period. As shown in Figure 11, if the adjusted period is greater than the original period, the time interval between the last SSB received at the first moment after ΔT3 and before the end of ΔT3 is T. B Furthermore, the first moment is the first moment after the end of △T3 that satisfies the above requirements. Figure 11 shows the time interval T between the first moment and the last SSB received before the end of △T3. B For example, twice the amount of [the product / service].

[0091] In other implementations, the time at which the third information is correctly decoded can be considered to avoid inconsistencies in the understanding of the SSB between the terminal device and the network device. For example, the first time point is located after the second time point, and the time interval between the first time point and the last received SSB before the second time point is an integer multiple of the adjusted period. The second time point can be the moment when it is determined that the third information has been correctly decoded; for example, the third information can be the moment when ACK information for the third information is sent or received.

[0092] In some implementations, the multiple period configurations indicated by the first information are associated with the cell's discontinuous transmission (DTX). For example, the activation time corresponding to DTX corresponds to the first period configuration, and 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; therefore, the first period can be shorter than the second period. In other words, SSB transmission is performed based on a longer period during the inactive period corresponding to DTX, and based on a shorter period during the activation time corresponding to DTX. Considering the measurement requirements of the activation time, the start time of the shorter period SSB transmission can be earlier than the start time of the activation time.
