[0027] The technical solutions in the present application will be described below with reference to the accompanying drawings.

[0028] FIG. 1 is an example diagram of a system architecture of a wireless communication system 100 to which embodiments of the present application can be applied. The wireless communication system 100 can include a network device 110 and a terminal device 120. The network device 110 can be a device that communicates with the terminal device 120. The network device 110 can provide network coverage for a specific geographic area, and can communicate with the terminal device 120 located within the coverage area. The terminal device 120 can access a network, such as a wireless network, through the network device 110. Optionally, the wireless communication system 100 can further include a network controller, a mobility management entity, and other network entities, which are not limited by embodiments of the present application.

[0029] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as a fifth generation (5G) system or new radio (NR), a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD), and the like. The technical solutions provided by the present application can also be applied to future communication systems, such as a sixth generation mobile communication system, a satellite communication system, and the like.

The terminal device in the embodiments of the present application can refer to a device providing voice and / or data connectivity for a user, and can be used to connect people, things and machines, such as handheld devices with wireless connection function, vehicle-mounted devices, etc. The terminal device in the embodiments of the present application can be a mobile phone, a tablet computer (Pad), a notebook computer, a palm computer, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. Optionally, the terminal device can be used to act as a base station. For example, the terminal device can act as a scheduling entity, which provides sidelink signals between terminal devices in vehicle to everything (V2X) or device to device (D2D), etc. For example, a cellular phone and a car communicate with each other using sidelink signals. The cellular phone and the smart home device communicate with each other without relaying the communication signals through the base station.

[0031] In embodiments of the present application, the network device can be a device for communicating with a terminal device. The network device can be, for example, an access network device or a radio access network device. For example, the network device can be a base station. The base station can broadly cover various names in the following or can be replaced with the following names, for example: Node B (Node B), evolved Node B (eNB), next generation Node B (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), master station (MeNB), secondary station SeNB (SeNB), multi-standard radio (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. The base station can be a macro base station, a micro base station, a relay node, a donor node, or the like, or a combination thereof. The base station can also refer to a communication module, modem, or chip for being disposed in the aforementioned device or apparatus. The base station can also be a mobile switching center and a device that assumes a base station function in device-to-device (D2D), vehicle-to-everything (V2X), machine-to-machine (M2M) communication, a network side device in a 6G network, a device that assumes a base station function in a future communication system, etc. The base station can support networks of the same or different access technologies. Embodiments of the present application do not limit the specific technology and specific device form adopted by the network device.

[0032] The base station can be fixed or mobile. For example, a helicopter or a drone can be configured to act as a mobile base station, and one or more cells can move according to the location of the mobile base station. In other examples, a helicopter or a drone can be configured to act as a device that communicates with another base station.

[0033] In some deployments, the network device can refer to a CU or a DU; or the network device includes a CU and a DU. The gNB can also include an AAU.

[0034] The network device and the terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on water; and can also be deployed on airplanes, balloons and satellites in the air. The scene in which the network device and the terminal device are located is not limited in the embodiments of the present application.

[0035] It should be understood that all or part of the functions of the communication device in the present application can also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform such as a cloud platform.

[0036] In the NR system, the network device can periodically transmit an SSB, which can be used for the terminal device to keep synchronization with the network device or perform cell measurement, etc. In the scenario of carrier aggregation (CA), when a secondary cell (SCell) is configured for the terminal device, the network device can configure the transmission of the SSB in the secondary cell. Since the SSB is a periodically transmitted reference signal, and will be transmitted in the cell after being configured, the continuous transmission of the SSB in the cell cannot guarantee that each SSB can be effectively utilized by the terminal device, and also increases potential energy consumption and resource waste. In order to solve this problem, the related technology adopts the way of increasing the transmission period of the SSB, so that the distribution of the SSB in the time domain will not be too close. However, this way will cause the terminal device that actually needs the SSB to wait for a long time to receive the SSB, thereby affecting the synchronization performance of the terminal device, and further affecting the system performance. Another way adopted in the related technology is to transmit the SSB only when it is needed. This way needs effective interaction between the network device and the terminal device, for example, the transmission of the SSB can be activated or deactivated by the network device. Further, in order to improve the flexibility of SSB transmission, the network device can configure multiple sets of SSBs for the terminal device, and each set of SSBs can be activated or deactivated by the network device. However, there is no solution for how to implement the application of multiple sets of SSBs at present.

[0037] Therefore, in the embodiments of the present application, the network device can configure multiple sets of SSBs for a cell to improve the flexibility of SSB transmission. In this scenario, the terminal device can perform a first operation associated with the SSB based on a target SSB configuration associated with the first operation in the multiple SSB configurations indicated by the first information, so that the scheme of the multiple SSB configurations can be effectively applied. In this way, by optimizing the operation associated with the SSB, the system performance is improved.

[0038] Next, an embodiment of the present application will be described in detail in combination with FIG. 2.

[0039] In this embodiment, it can be assumed that each terminal device is connected with one serving cell, e.g., a primary cell (PCell), and the primary cell can configure the terminal device by adding a secondary cell. In the secondary cell, the network device can configure one or more sets of SSBs, wherein the transmission of each set of SSBs can be activated or deactivated by the network device. It can be understood that the configuration of multiple sets of SSBs in this embodiment can be understood as the network device sending multiple sets of SSB configurations (i.e., multiple sets of SSB configuration information) to the terminal device. Each set of SSB configuration information includes at least one parameter for SSB transmission, and at least some parameters in the multiple sets of SSB configuration information are different.

[0040] FIG. 2 is a flowchart of a wireless communication method according to an embodiment of the present application. The method 200 shown in FIG. 2 can be performed by a terminal device. The terminal device may, for example, be the terminal device 120 shown in FIG. 1.

[0041] Referring to FIG. 2, in step 210, the terminal device performs a first operation based on first information.

[0042] The first information is used to indicate a target SSB configuration associated with the first operation in the multiple sets of SSB configurations.

[0043] In the embodiments of the present application, the multiple sets of SSBs can correspond to multiple SSB bursts. Each SSB burst includes multiple SSBs with different SSB indexes. The SSB indexes in the SSB bursts corresponding to the multiple sets of SSB configurations can be partially or entirely the same, that is, the SSB bursts corresponding to the multiple sets of SSB configurations can include SSBs with the same SSB index. In addition, the same SSB index in the SSB bursts corresponding to the multiple sets of SSB configurations can correspond to different directions. In some implementations, the first information is also used to indicate the SSB index corresponding to the first operation.

[0044] In the above case, when the terminal device performs the first operation associated with the SSB, it needs to distinguish the SSBs with the same SSB index but belonging to different SSB bursts. To this end, the terminal device can perform the first operation associated with the SSB based on the target SSB configuration associated with the first operation in the multiple sets of SSB configurations indicated by the first information.

[0045] In some implementations, the frequencies (or frequency points) of the SSBs in the multiple sets of SSB configurations are different; and / or, the time domain positions of the SSBs in the multiple sets of SSB configurations are different; and / or, the subcarrier spacings of the SSBs in the multiple sets of SSB configurations are different.

[0046] As an example, as shown in FIG. 3, the network device can configure multiple sets of SSBs on different frequencies for each cell. In FIG. 3, two sets of SSB configurations are taken as an example, assuming that the frequencies corresponding to the two sets of SSB configurations are f1 and f2 respectively, for example, SSB transmission based on the first set of SSB configurations is on f1 (see row 1 in FIG. 3), and SSB transmission based on the second set of SSB configurations is on f2 (see row 2 in FIG. 3). Among them, the SSB indexes in the SSB bursts corresponding to the two sets of SSB configurations are the same, the SSB indexes in the SSB burst transmitted on f1 include SSB 0, SSB 1, SSB 2 and SSB 3, and the SSB indexes in the SSB burst transmitted on f2 also include SSB 0, SSB 1, SSB 2 and SSB 3.

[0047] As another example, as shown in FIG. 4, the network device can configure multiple sets of SSBs with different time domain positions for each cell. In FIG. 4, two sets of SSB configurations are taken as an example, assuming that the subcarrier spacings corresponding to the two sets of SSB configurations differ by 1 times, for example, the subcarrier spacing corresponding to the first set of SSBs is f3 (see row 1 in FIG. 4), and the subcarrier spacing corresponding to the second set of SSBs is f4 (see row 2 in FIG. 4), f3 = 2*f4. Among them, the SSB indexes in the SSB bursts corresponding to the two sets of SSB configurations are the same, and both include SSB 0 and SSB 1. Each small square in FIG. 4 represents 1 symbol, and due to the difference in subcarrier spacing, the symbol length of the SSBs in the two sets of SSB configurations is also different.

[0048] In some implementations, the time domain positions of the SSBs in the multiple sets of SSB configurations do not overlap; or, the time domain positions of the SSBs in the multiple sets of SSB configurations at least partially overlap. For example, the time domain positions of the SSBs in the multiple SSB bursts on different frequencies can be the same or different, FIG. 3 is taken as an example in which the time domain positions of the SSBs in the multiple SSB bursts are different and do not overlap, and FIG. 4 is taken as an example in which the time domain positions of the SSBs in the multiple SSB bursts at least partially overlap. Of course, the cases shown in FIG. 3 and FIG. 4 can also exist simultaneously, that is, the frequencies and subcarrier spacings corresponding to the two sets of SSB configurations are all different, for example, the frequency corresponding to the first set of SSB configurations is f1 and the subcarrier spacing is f3, and the frequency corresponding to the second set of SSB configurations is f2 and the subcarrier spacing is f4, or the frequency corresponding to the first set of SSB configurations is f1 and the subcarrier spacing is f4, and the frequency corresponding to the second set of SSB configurations is f2 and the subcarrier spacing is f1.

[0049] The target SSB configuration described above can be configured by the network device, or selected by the terminal device.

[0050] In some implementations, in a case where the terminal device supports single-direction SSB reception, the target SSB configuration includes one set of SSB configurations; in a case where the terminal device supports multi-direction SSB reception, the target SSB configuration can include multiple sets of SSB configurations.

[0051] In a case where multiple sets of SSBs are configured, if the terminal device supports single-direction SSB reception, the network device can instruct the terminal device to use which set of SSB configurations for SSB reception or measurement, or the terminal device can select which set of SSB configurations to use for SSB reception or measurement; if the terminal device supports multi-direction SSB reception, the terminal device can also simultaneously perform SSB reception or measurement based on multiple sets of SSB configurations. It can be understood that the network device can simultaneously send SSBs in different directions, but the terminal device does not necessarily support simultaneously performing SSB reception in multiple directions.

[0052] In some implementations, the first operation includes one or more of the following: SSB reception based on the target SSB configuration; reporting of a measurement result based on the target SSB configuration; reporting of a reselection beam corresponding to the target SSB configuration after beam failure recovery; downlink reception having a quasi co-located (QCL) relationship with the target SSB configuration.

[0053] The downlink reception, for example, includes one or more of the following: reception of a physical downlink control channel (PDCCH); reception of a signal status information-reference signal (CSI-RS); and reception of a physical downlink shared channel (PDSCH).

[0054] In the embodiments of this application, the first information can be sent by the terminal device to the network device, and accordingly, the network device receives the first information sent by the terminal device, and the first information is used to indicate a target SSB configuration associated with the first operation in multiple sets of SSB configurations. For example, for scenarios where the first operation includes reporting of a measurement result based on the target SSB configuration, reporting of a reselection beam corresponding to the target SSB configuration after beam failure recovery, etc., the terminal device can send the first information to the network device at the same time as reporting the measurement result or reporting the reselection beam, to inform the network device which SSB index in which SSB configuration the reported measurement result is for, or which SSB index in which SSB configuration the reported reselection beam is for.

[0055] The first information can also be indicated by the network device to the terminal device or determined by the terminal device. For example, for scenarios including SSB reception based on the target SSB configuration, downlink reception having a QCL relationship with the target SSB configuration, and the like, the terminal device performs SSB reception and measurement based on the SSB index and the target SSB configuration to which the SSB index belongs indicated by the first information, or performs corresponding downlink reception.

[0056] The following illustrates several possibilities of the first operation.

[0057] For example, the first operation includes SSB reception based on the target SSB configuration. The terminal device can perform SSB reception based on the target SSB configuration in the multiple sets of SSB configurations. It can be understood that the SSB reception described in the embodiments of the present application can also be regarded as SSB measurement or SSB detection, and the corresponding measurement result is obtained by performing SSB measurement after the terminal device performs SSB reception.

[0058] For another example, the first operation includes reporting of a measurement result based on the target SSB configuration, for example, reporting of signal status information (CSI) based on SSB measurement, the measurement result including, for example, a measurement result of reference signal received power (RSRP) and the like, wherein the measurement result of RSRP includes, but is not limited to, a measurement result of layer 1 RSRP (L1-RSRP) and / or a measurement result of layer 3 RSRP (L3-RSRP). When the terminal device reports the CSI, the measurement report carries information such as the measurement value of RSRP, and needs to carry the first information, which is used not only to indicate the SSB index associated with the first operation, but also to indicate the target SSB configuration to which the SSB belongs, so that the network device knows which set of SSB configurations the SSB index belongs to.

[0059] For another example, the first operation includes reporting of a reselected beam corresponding to the target SSB configuration after beam failure recovery. After the terminal device selects a beam from the candidate beams for beam failure recovery (BFR), the terminal device reports an SSB index associated with the selected beam to the network device, and needs to indicate the target SSB configuration to which the SSB belongs through the first information, so that the network device knows which set of SSB configurations the SSB index belongs to.

[0060] For example, the first operation includes downlink reception with a QCL relationship with the target SSB configuration, such as PDCCH reception, CSI-RS reception, PDSCH reception, etc. The terminal device not only needs to know the SSB index used for downlink reception, but also needs to know the target SSB configuration to which the SSB belongs, so as to perform downlink reception based on the SSB index in the target SSB configuration indicated by the first information, wherein the direction corresponding to the SSB index is the direction of the downlink reception.

[0061] In some implementations, the first information may include one or more of the following: the index of the target SSB configuration; the frequency information of the SSB in the target SSB configuration; the subcarrier spacing of the SSB in the target SSB configuration; the time-domain location information of the SSB in the target SSB configuration; the information of the PUSCH associated with the target SSB configuration among multiple PUSCHs; and the information of the time-domain location associated with the target SSB configuration among multiple time-domain locations within the PUSCH.

[0062] The first information indicates the target SSB configuration by specifying the index of the target SSB configuration, the frequency information of the SSB in the target SSB configuration, the subcarrier spacing of the SSB in the target SSB configuration, and the time-domain position information of the SSB in the target SSB configuration. For example, continuing to refer to Figure 3, when the first information indicates an SSB index (e.g., SSB 0, SSB 1, SSB 2, or SSB 3), it can simultaneously carry information about the frequency to which that SSB index belongs (e.g., f1 or f2). As another example, continuing to refer to Figure 4, when the first information indicates an SSB index (e.g., SSB 0 or SSB 1), it can simultaneously carry information about the subcarrier spacing (e.g., f3 or f4) corresponding to the SSB configuration to which that SSB index belongs. Furthermore, multiple SSBs can have their own configuration indices, and the first information can carry the configuration index corresponding to the target SSB configuration.

[0063] In addition, the first information can also indicate the target SSB configuration in an implicit indication manner. For example, a plurality of sets of SSB configurations are associated with a plurality of PUSCHs, when the terminal device indicates the target SSB configuration associated with the first operation (e.g., measurement result reporting or beam reselection reporting) to the network device, the terminal device can report by using the PUSCH associated with the target SSB configuration, and the network device can determine the target SSB configuration to which the SSB index carried in the reporting content belongs according to the PUSCH in which the reporting content is located. For another example, a PUSCH corresponds to a time domain range including a plurality of time domain positions, the plurality of time domain positions have different time domain orders, a plurality of sets of SSB configurations are associated with the plurality of time domain positions in the PUSCH, when the terminal device indicates the target SSB configuration associated with the first operation (e.g., measurement result reporting or beam reselection reporting) to the network device, the terminal device can report by using the time domain position associated with the target SSB configuration in the PUSCH, and the network device can determine the target SSB configuration to which the SSB index carried in the reporting content belongs according to the time domain position (or the time domain order) in which the reporting content is located.

[0064] In the following, another embodiment of the present application will be described in detail in combination with FIG. 5.

[0065] FIG. 5 is a flow diagram of a wireless communication method provided by another embodiment of the present application. The method 500 shown in FIG. 5 can be performed by a terminal device. The terminal device can be, for example, the terminal device 120 shown in FIG. 1.

[0066] In this embodiment, the network device can configure one set of SSBs or a plurality of sets of SSBs for the terminal device. For each set of SSB configuration, the method 500 described in this embodiment can be performed.

[0067] Referring to FIG. 5, in step 510, the terminal device performs a second operation associated with the SSB based on the activation time of the SSB.

[0068] It can be understood that the activation time of the SSB can be considered as the time of SSB transmission, and there is no SSB transmission at other times outside the activation time. As an example, the activation time of the SSB may, for example, be based on an activation indication or a deactivation indication of the network device. That is, the network device can send an activation indication information to the terminal device, and the terminal device receives the activation indication information accordingly, which is used to indicate the activation of the SSB, or in other words, to indicate the starting moment of the activation time of the SSB. The network device can also send a deactivation indication information to the terminal device, and the terminal device receives the deactivation indication information accordingly, which is used to indicate the deactivation of the SSB, or in other words, to indicate the ending moment of the activation time of the SSB. Alternatively, the activation indication information and / or the deactivation indication information can be carried in a media access control control element (MAC CE) or a downlink control message (DCI). Of course, in addition to the way in which the network device sends the activation indication information and / or the deactivation indication information, the activation and / or deactivation of the SSB can also be achieved by other ways, and the embodiments of the present application do not limit this.

[0069] Since the terminal device performs the second operation associated with the SSB based on the activation time of the SSB, the second operation associated with the SSB is matched with the on-demand transmitted SSB, and then the scheme of transmitting the SSB on demand is applied, which is beneficial to network energy saving.

[0070] In some implementations, the second operation can include reporting a measurement result of the SSB in the activation time. Wherein, the SSB transmission is semi-persistent, that is, the network device can activate the SSB transmission in a period of time. The network device can send SSB configuration information to the terminal device through, for example, RRC signaling, for example, including parameters for SSB transmission such as period, frequency, subcarrier spacing, transmit power, cell identity, SSB position in SSB burst, etc., and the network device will activate the SSB transmission when it needs SSB transmission. The terminal device can perform the second operation based on these parameters after the SSB is activated, for example, receive and measure the SSB, and report the measurement result, for example, report the CSI based on the SSB measurement. Wherein, the SSB can have a periodicity in the activation time of the SSB. The periodicity of the SSB and the semi-persistent can be changed by activation and / or deactivation.

[0071] Since there is SSB transmission only in the activation time of SSB, the measurement result reported by the terminal device to the network device is the measurement result of SSB in the activation time. The measurement result includes, for example, the measurement result of RSRP, etc., wherein the measurement result of RSRP includes, but is not limited to, the measurement result of L1-RSRP and / or the measurement result of L3-RSRP. When the terminal device reports the measurement result, the measurement report carries information such as the RSRP measurement value in the activation time.

[0072] In some implementations, the time for reporting the measurement result of SSB in the activation time is located in the activation time or in a predetermined time period after the end time of the activation time. Although the reported content includes the measurement result of SSB in the activation time, the time for reporting the measurement result can be located in the activation time or after the activation time. As an example, the terminal device receives the activation indication information sent by the network device at T0, receives the deactivation indication information sent by the network device at T1, and is configured with T2 after T1. The terminal device can report in the time period between T0 and T2 and the reported content includes the measurement result of SSB in the time period between T0 and T1. The time interval between T2 and T1 should not be too large, for example, the time interval between T2 and T1 can be less than a preset value.

[0073] In some implementations, in the TDD mode, in the case that the activation time overlaps with the random access channel opportunity RO configured by the network device, or the interval time between the activation time and the RO is not sufficient for switching between uplink and downlink transmission, the second operation described above can further include preferentially performing SSB reception or preferentially performing physical random access channel (PRACH) transmission.

[0074] In the case that the network device configures PRACH resources for transmitting PRACH and the network device operates in the TDD mode, if the activation time of SSB conflicts with (or overlaps with) the random access channel (RACH) opportunity (RO) or there is not enough interval time between the activation time of SSB and the RO for switching between uplink and downlink or switching between downlink and uplink (or switching between Rx and Tx or switching between Tx and Rx), the terminal device can preferentially perform SSB reception or preferentially perform PRACH transmission. Whether to preferentially perform SSB reception or preferentially perform PRACH transmission can be indicated by the network device or determined by the terminal device, for example, preferentially performing PRACH transmission when the terminal device has urgent traffic to send, and preferentially performing SSB reception in other cases.

[0075] In some implementations, the second operation described above can further include determining, based on a mapping relationship between the candidate SSB positions in the SSB burst and the ROs, valid ROs and / or invalid ROs in the ROs having the mapping relationship with the candidate SSB positions. The information of the mapping relationship can be carried in the RRC signaling sent by the network device, for example. The valid ROs are ROs corresponding to the activated SSB positions in the candidate SSB positions, for example, and the invalid ROs are ROs corresponding to the unactivated SSB positions in the candidate SSBs, for example. The valid ROs can be ROs used for PRACH transmission, and the invalid ROs are not used for PRACH transmission.

[0076] For example, in an SSB burst, there is a set of candidate SSB positions (or SSB indexes), and the network device can activate part or all of the candidate SSB positions. The candidate SSB positions can have a mapping relationship (or an association relationship) with the ROs, and each candidate SSB can be mapped to an RO. As an example, as shown in FIG. 6, the SSB burst includes four SSB positions, i.e., positions corresponding to SSB indexes SSB 0, SSB 1, SSB 2, and SSB 3, where the position of SSB 0 is associated with RO 0, the position of SSB 1 is associated with RO 1, the position of SSB 2 is associated with RO 2, and the position of SSB 3 is associated with RO 3. Assuming that the network device activates SSB transmission and only activates SSB 0 and SSB 1, and SSB 2 and SSB 3 are not activated, then the RO 0 associated with the position of SSB 0 (i.e., the RO 0 mapped to SSB 0) and the RO 1 associated with the position of SSB 1 (i.e., the RO 1 mapped to SSB 1) are valid, and therefore RO 0 and RO 1 can be used for PRACH transmission, while the RO 2 associated with the position of SSB 2 (i.e., the RO 2 mapped to SSB 2) and the RO 3 associated with the position of SSB 3 (i.e., the RO 3 mapped to SSB 3) are invalid, and RO 2 and RO 3 are not used for PRACH transmission. In addition, before SSB activation, RO 0, RO 1, RO 2, and RO 3 are all invalid. The “X” shown in FIG. 6 indicates that the RO is invalid. As can be seen from FIG. 6, in the case where the SSB is not activated, all the ROs associated with the SSB indexes are invalid; in the case where the SSB is activated, the ROs associated with the activated SSB indexes in the activation time are valid, and the ROs associated with the unactivated SSB indexes in the activation time are invalid.

[0077] In this embodiment, the candidate SSB positions may, for example, include SSB positions that can be activated in an SSB burst. That is, when the terminal device performs SSB-to-PRACH mapping, the terminal device assumes that all candidate SSB positions are considered for SSB-to-PRACH mapping, i.e., all possible SSB positions are involved in SSB-to-PRACH mapping, not just the currently activated SSB positions.

[0078] The technical solutions described in the embodiments of the present application are all adapted to the SSB transmission involved, which can be referred to as SSB adaptation. That is, the operations related to SSB (e.g., the first operation and the second operation described above) are all adaptively changed based on the changes in SSB transmission (e.g., changes in the target SSB configuration in the multiple sets of SSB configurations and / or changes in the SSB activation time) to adapt to the SSB transmission. Among them, the SSB that is activated when needed can be referred to as an on-demand SSB, and the SSB whose SSB configuration changes or activation time changes can be referred to as an adaptation SSB, and the SSB described in the embodiments of the present application can be an on-demand SSB or an adaptation SSB. In addition, the technical solutions of the embodiments of the present application can be applied to communication in any frequency band, such as communication in the unlicensed frequency band of 5G NR or other licensed frequency bands.
