[0041] In the above embodiment, the terminal receives indication information. Since the indication information can indicate the transmission status of the SSB, the terminal can determine the corresponding SSB transmission status based on the indication information, so that corresponding processing can be performed.

[0043] In the above embodiment, the indication information is the activation or deactivation signaling of the secondary cell, which can enable the terminal to determine the indication of the transmission status of the SSB based on the activation or deactivation signaling of the secondary cell.

The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0107] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0109] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only.

[0110] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0111] In order to reduce the energy consumption of network devices in a communication system, in some embodiments, for example, for the communication transmission of synchronization signals and broadcast channel blocks (Synchronization Signal and PBCH block, SSB), an on-demand SSB scheme is proposed. Figure 1B is a schematic diagram of the on-demand SSB scheme shown in accordance with an embodiment of the present disclosure. As shown in Figure 1B, on the time line, the network device does not continuously send SSB. Assuming that the first time domain resources of the time line and the third time domain resources of the time line meet the sending requirements of on-demand SSB, the network device will send SSB (for example, corresponding to the unfilled part in Figure 1B). If the second time domain resources of the time line do not meet the sending requirements of on-demand SSB, the network device will not send SSB (for example, corresponding to the filled part in Figure 1B).

[0112] It should be noted that the terms “send SSB”, “send SSB”, “start SSB sending”, “SSB on”, etc. can be used interchangeably.

[0113] It should be noted that the terms “will not send SSB”, “do not send SSB”, “turn off SSB sending”, “SSB off”, etc. can be used interchangeably.

[0114] It is understandable that the application scenario of on-demand SSB is the carrier aggregation (CA) scenario. In this scenario, in order to achieve network energy saving, the secondary cell (scell) may suspend the transmission of the downlink signal SSB. Since the secondary cell does not continuously transmit SSB, if the terminal is unaware that the secondary cell has turned off SSB transmission (for example, in the second time domain resource position in Figure 1B), it still receives SSB or performs measurement reporting, which will cause unnecessary resource waste and related power loss.

[0115] Therefore, how to ensure that the terminal can accurately transmit SSB in the on-demand SSB scenario is a problem that needs to be solved.

[0116] However, in some embodiments, there will also be a process of activating and deactivating a secondary cell in a CA scenario. There is a mechanism for activating and deactivating a secondary cell in the existing protocol, for example:

[0117] In some embodiments, such as in a CA scenario, the primary cell (Pcell) manages the secondary cell. For example, the management of the secondary cell generally includes at least one of the following: adding or deleting the secondary cell; activating or deactivating the secondary cell. Figure 1C is a schematic diagram of the secondary cell status according to an embodiment of the present disclosure. The management status of the primary cell over the secondary cell can be as shown in Figure 1C, wherein the activation of the secondary cell can be achieved through a Media Access Control (MAC) control unit (CE).

[0118] In some embodiments, activation or deactivation of the secondary cell may be achieved by any one of the following methods 1) to 3):

[0119] -1) During configuration, the secondary cell is indicated as being in an activated state. If the secondary cell is not indicated as being in an activated state, the secondary cell is considered to be in a deactivated state.

[0120] -2) Activation is performed through a Media Access Control Element (MAC CE) used to activate the secondary cell, and deactivation is performed through a MAC CE used to deactivate the secondary cell.

[0121] -3) For an activated secondary cell, whether to activate it is determined in a timing manner.

[0122] For method 2), activation of the secondary cell is subject to a certain delay. This is because after receiving the activation signaling, the user must attempt to receive the downlink reference signal for automatic gain control and downlink time-frequency synchronization. However, the time domain position of the Scell's SSB or periodic TRS may not match the timing of the Scell ​​activation signaling. In other words, after receiving the activation signaling, the user may need to wait for a while before receiving the downlink reference signal.

[0123] It should be noted that the delay T of the secondary cell can be calculated using formula (1):

[0124] Among them, T HARQ T is the time used for hybrid automatic repeat request (HARQ), activation_time T is the activation time. CSI_Reporting The time used for Channel State Information (CSI) reporting. NR slot length indicates the time slot length.

[0125] In some embodiments, taking a known secondary cell (known scell) as an example, where T activation_time =T First SSB +5ms, T First SSB The time it takes to receive the SSB for the first time. That is, there is a 5ms delay from the first reception of the SSB to the formal activation of the secondary cell.

[0126] In some embodiments, in order to reduce the delay caused by the above-mentioned method -2), a secondary cell activation method based on a tracking reference signal (TRS) is proposed. Including, for example, activating TRS while activating the secondary cell. Figure 1D is a schematic diagram of a secondary cell activation method based on TRS according to an embodiment of the present disclosure. As shown in Figure 1D, in the same bandwidth (for example, Band A), after the primary cell activates the scell (for example, cell 2) through (for example, cell 1) MAC CE, the network immediately sends a TRS. The user activates the TRS to complete downlink synchronization and automatic gain control. Then the activation delay of the scell is T activation_time T FirstATRS +5ms. Since TRS is sent immediately after activation signaling. FirstATRS The smaller the value of , the shorter the overall activation delay.

[0127] However, activation through secondary cells is only applicable to known secondary cells. It should be noted that, taking frequency range 1 (FR) as an example, before receiving the activation signaling. Within a certain period of time, the user has reported a valid measurement result. Moreover, the SSB for which the measurement result is obtained can still be detected. In addition, the SSB can still be detected for a period of time after activation. Then such a secondary cell is called a known secondary cell. However, the secondary cells that can currently support on-demand SSB may also have unknown secondary cells (unknown scells) other than known secondary cells, including, for example: intra-band hopping secondary cells (intra-band scells) and inter-band secondary cells (inter-band scells). In the case that the secondary cell is an unknown secondary cell, the TRS-based activation method will no longer be used.

[0128] Based on this, an embodiment of the present disclosure proposes a communication method for enabling a terminal to accurately determine the transmission status of an on-demand SSB and simultaneously activate or deactivate a secondary cell.

[0129] FIG2A is a schematic diagram illustrating an interaction of a communication method according to an embodiment of the present disclosure. As shown in FIG2A , the present disclosure embodiment relates to a communication method for use in a communication system 100, the method comprising:

[0130] In step S2101 , the network device 102 sends instruction information to the terminal 101 .

[0131] In some embodiments, the terminal 101 receives indication information sent by the network device 102, where the indication information is used to indicate the transmission status of the SSB, where the transmission status includes an on state or a off state.

[0132] It should be noted that the transmission state is the on state, which can be understood as the network device 102 turning on the transmission of SSB, including, for example: the network device 102 starts sending SSB, and / or the terminal 101 starts receiving the SSB sent by the network device 102. The transmission state is the off state, which can be understood as the network device 102 turning off the transmission of SSB, including, for example: the network device 102 stops sending SSB, and / or the terminal 101 stops receiving the SSB sent by the network device 102.

[0133] It can be understood that by sending indication information to the terminal 101, since the indication information can indicate the transmission status of the SSB, the terminal 101 can determine the corresponding SSB transmission status based on the indication information, so that corresponding processing can be performed. For example, the terminal 101 determines that the transmission status of the SSB is on based on the indication information (for example, the network device 102 starts sending the SSB), then the terminal 101 can receive the SSB accordingly. For another example, the terminal 101 determines that the transmission status of the SSB is off based on the indication information (for example, the network device 102 stops sending the SSB), then the terminal 101 can stop receiving the SSB accordingly, thereby reducing the user's unnecessary resource occupation and power overhead caused by invalid measurement and reporting.

[0134] However, how the indication information indicates the transmission status of the SSB can be implemented through different indication information. For different indication information, the following -1) or -2) can be included:

[0135] -1) The indication information is activation or deactivation signaling of a secondary cell.

[0136] -2) The indication information is a second signaling, wherein the second signaling is used to indicate the transmission status of the SSB, or the activation or deactivation of the secondary cell.

[0137] In some embodiments, for -1), when the indication information is the activation signaling of the secondary cell, the terminal 101 turns on the SSB transmission state based on the activation signaling of the secondary cell.

[0138] It can be understood that when the terminal 101 turns on the SSB transmission state based on the activation signaling of the secondary cell, there may be three ways of turning on the SSB transmission state: -1-1), -1-2) and -1-3):

[0139] -1-1) Terminal 101 turns on the SSB transmission state for N cycles and then turns it off.

[0140] -1-2) Terminal 101 turns on the SSB transmission state for a specific period of time and then turns it off.

[0141] -1-3) The terminal 101 keeps the SSB transmission state on until it is turned off upon receiving the secondary cell deactivation signaling.

[0142] For -1-1), after receiving the activation signaling of the secondary cell, the terminal starts to receive the SSB and receives the SSB for at least N periods, where N is an integer greater than or equal to 1.

[0143] Optionally, N is determined based on protocol provisions or network instructions.

[0144] For ease of understanding, the description will be made based on Figure 2B for -1-1). Figure 2B is a schematic diagram of SSB transmission based on activation signaling of a secondary cell according to an embodiment of the present disclosure. As shown in Figure 2B, the terminal 101 receives the activation signaling of the secondary cell at time t0 (for example, the terminal 101 receives the activation signaling of the secondary cell sent by the network device 102). After receiving the activation signaling of the secondary cell, the terminal 101 determines that the network device 102 starts SSB transmission for N cycles and receives the SSB sent by the network device 102. In this way, the terminal 101 can determine that the network device 102 starts SSB transmission based on the indication information.

[0145] However, at time t1 (i.e., the SSB transmission state is turned on for N cycles), the secondary cell is activated. If the subsequent network device 102 turns off the SSB transmission state or the terminal 101 can determine whether the SSB transmission state is turned on after time t1 based on other display instructions or reference signals. Including, for example, at time t1, based on the first signaling (for example, the terminal 101 receives a display instruction sent from the network device 102), it is known that the network device 102 stops sending SSB, then the terminal 101 will turn off the SSB transmission state after time t1 (that is, corresponding to the dotted box in Figure 2B). Similarly, if at time t1, based on the display instruction, it is known that the network device 102 sends SSB, then the terminal 101 will continue to turn on the SSB transmission state after time t1 (that is, corresponding to the solid box in Figure 2B). It should be noted that the first signaling (for example, the terminal 101 receives a display instruction sent from the network device 102) can be included in the indication information, or carried in the indication information, and the first signaling is different from the activation signaling or deactivation signaling of the secondary cell.

[0146] For another example, if it is known at time t1 based on the reference signal that the network device 102 stops sending SSB (for example, based on measurement of the reference signal, or prediction, etc.), the terminal 101 will turn off the SSB transmission state after time t1 (that is, corresponding to the dotted box in Figure 2B). Similarly, if it is known at time t1 based on the reference signal that the network device 102 sends SSB, the terminal 101 will continue to turn on the SSB transmission state after time t1 (that is, corresponding to the solid box in Figure 2B). The reference signal includes, for example, a demodulation reference signal (Dedicated Reference Signal, DRS) or SSB. It should be noted that the terminal 101 can determine whether the SSB transmission state after time t1 is turned on based on other display instructions or reference signals. The embodiments of the present disclosure are only illustrative examples and are not limiting.

[0147] For -1-2), after receiving the activation signaling of the secondary cell, the terminal 101 starts to receive the SSB and receives the SSB within T time.

[0148] Optionally, the specific duration may be understood as a fixed time length (including, for example, 1 time window, n time slots / symbols, etc.), and the specific duration is based on protocol provisions or determined based on network configuration.

[0149] For ease of understanding, the description will be based on Figure 2C for -1-2). Figure 2C is a schematic diagram of SSB transmission based on activation signaling of a secondary cell according to an embodiment of the present disclosure. As shown in Figure 2C, the terminal 101 receives the activation signaling of the secondary cell at time t0 (for example, the terminal 101 receives the activation signaling of the secondary cell sent by the network device 102). After receiving the activation signaling of the secondary cell, the terminal 101 determines that the network device 102 performs SSB transmission for T time (that is, a fixed duration, including, for example, 1 time window, etc.), and receives the SSB sent by the network device 102. In this way, the terminal 101 can determine that the network device 102 starts SSB transmission based on the indication information.

[0150] However, at time t1 (that is, the SSB transmission state is turned on for a fixed period of time), the secondary cell is activated. If the network device 102 subsequently turns off the SSB transmission state or the terminal 101 can determine whether the SSB transmission state is turned on after time t1 based on other display instructions or reference signals. It should be noted that the first signaling (for example, the terminal 101 receives a display instruction sent by the network device 102) can be included in the indication information, or carried in the indication information. The first signaling is different from the activation signaling or deactivation signaling of the secondary cell.

[0151] For another example, if it is known based on the reference signal at time t1 that the network device 102 stops sending SSB (for example, based on measurement of the reference signal, or prediction, etc.), the terminal 101 will turn off the SSB transmission state after time t1 (that is, corresponding to the dotted box in Figure 2C). Similarly, if it is known based on the reference signal at time t1 that the network device 102 sends SSB, the terminal 101 will continue to turn on the SSB transmission state after time t1 (that is, corresponding to the solid box in Figure 2C). The reference signal includes, for example: DRS or SSB. It should be noted that the terminal 101 can determine whether the SSB transmission state after time t1 is turned on based on other display instructions or reference signals. The embodiments of the present disclosure are only illustrative examples and are not limiting.

[0152] For -1-3), after receiving the activation signaling of the secondary cell, the terminal 101 starts to receive the SSB, and after receiving the deactivation signaling of the secondary cell, the terminal 101 stops receiving the SSB.

[0153] For ease of understanding, description will be made based on Figure 2D for -1-3), which is a schematic diagram of SSB transmission based on activation signaling of a secondary cell according to an embodiment of the present disclosure. As shown in Figure 2D, the terminal 101 receives the activation signaling of the secondary cell at time t0. After receiving the activation signaling of the secondary cell, the terminal 101 determines that the network turns on SSB transmission. Before receiving the deactivation signaling of the secondary cell, the network will continue to turn on the SSB transmission state (for example, continue to receive the SSB sent by the network device 102). If at time t1, the terminal 101 receives the deactivation signaling of the secondary cell (for example, the terminal 101 receives the deactivation signaling of the secondary cell sent by the network device 102), the terminal 101 determines that the network will turn off the SSB transmission state (for example, corresponding to the dotted box in Figure 2D).

[0154] Based on this, when the indication information is activation or deactivation signaling of the secondary cell, it is clarified how the terminal determines the transmission status of the SSB based on the indication information.

[0155] In some embodiments, for -2), the terminal 101 determines the transmission status of the SSB based on the second signaling. It can be understood that if the second signaling is only used to indicate the transmission status of the SSB, the terminal 101 can determine whether the transmission status of the SSB is on or off based on the second signaling. If the second signaling can be used to simultaneously indicate the transmission status of the SSB and the activation or deactivation status of the secondary cell, the terminal 101 can simultaneously determine the transmission status of the SSB and determine whether the secondary cell is in an activated state or a deactivated state based on the second signaling. The second signaling can be at least one of downlink control information (DCI), MAC CE or radio resource control (RRC) signaling.

[0156] For ease of understanding, the description will be based on Figures 2E and 2F for -2). Figure 2E is a schematic diagram of SSB transmission based on the second signaling according to an embodiment of the present disclosure. As shown in Figure 2E, the second signaling simultaneously indicates that the secondary cell is activated and the SSB transmission state is turned on. After receiving the second signaling (including, for example, the terminal 101 receives the second signaling sent by the network device 102), it determines that the SSB transmission state is turned on and determines that the secondary cell is in an activated state.

[0157] FIG2F is a schematic diagram illustrating SSB transmission based on a second signaling according to an embodiment of the present disclosure. As shown in FIG2F , the second signaling only indicates the SSB transmission state (i.e., the SSB transmission on state at time t0 and the SSB transmission off state at time t1). Terminal 101 determines, based on the second signaling, that the SSB transmission state is on from time t0 to t1 and that the SSB transmission state is off after time t1.

[0158] It is understandable that if the second signaling is only used to indicate the transmission status of the SSB, it can be achieved by multiplexing the current signaling (such as MAC CE). If the second signaling can simultaneously indicate the transmission status of the SSB and the activation or deactivation status of the secondary cell, the indication field of the signaling needs to be set accordingly.

[0159] In some embodiments, when the second signaling is used to indicate the transmission status of the SSB and the activation or deactivation of the secondary cell, the second signaling includes a first indication field, a second indication field, and a third indication field. The first indication field is used to indicate whether the second signaling is used to indicate the transmission status of the SSB and the activation or deactivation of the secondary cell; the second indication field is used to indicate the identifier of the activated secondary cell; and the third indication field is used to indicate the transmission status of the SSB.

[0160] It can be understood that when the content indicated by the first indication field is the second signaling used to indicate the transmission status of the SSB, and the activation or deactivation of the secondary cell, the second signaling can be used to indicate the transmission status of the SSB, and the activation or deactivation of the secondary cell. When the content indicated by the first indication field is the second signaling used to indicate the transmission status of the SSB, and the activation or deactivation of the secondary cell, the secondary cell identifier indicated by the second indication field can be used to determine which secondary cells are in the activated state and which secondary cells are in the deactivated state. The transmission status of the SSB indicated by the third indication field can be used to know whether the transmission status of the SSB corresponding to the secondary cell is on or off.

[0161] Therefore, the terminal 101 can determine the SSB transmission status and whether the secondary cell needs to be activated through the second signaling.

[0162] However, how the second signaling can simultaneously indicate the transmission status of the SSB and the activation or deactivation of the secondary cell can be achieved through the content indicated by the bits in the second signaling.

[0163] In some embodiments, when the second signaling reuses the activation or deactivation signaling of the existing secondary cell, the second signaling includes a first bit and a second bit, wherein the first bit is used to indicate whether the second signaling is used to indicate the transmission status of the SSB.

[0164] It can be understood that, when the second signaling multiplexes the activation or deactivation signaling of the secondary cell, if the first bit indicates that the second signaling is used to indicate the transmission status of the SSB, the second signaling can be used to indicate the transmission status of the SSB when indicating the activation or deactivation of the secondary cell. If the first bit does not indicate that the second signaling is used to indicate the transmission status of the SSB, or the first bit indicates that the second signaling is not used to indicate the transmission status of the SSB, the second signaling only retains its original function (that is, for example, indicating the activation or deactivation of the secondary cell based on the second indication field).

[0165] For ease of understanding, the case where the second signaling is activation or deactivation signaling of a secondary cell will be described based on Figures 2G to 2H. Figure 2G is a schematic structural diagram of a second signaling according to an embodiment of the present disclosure. As shown in Figure 2G, the position where "0" is located is the first bit. Assuming that the value of the first bit is "0", it is assumed that the first bit indicates that the second signaling is not used to indicate the transmission status of the SSB. The first bit indicates that the second signaling is only used to indicate the activation or deactivation of the secondary cell. Among them, C1 to C7 are identifiers corresponding to the secondary cell list.

[0166] Figure 2H is a schematic diagram of the structure of a second signaling according to an embodiment of the present disclosure. As shown in Figure 2H, the position where "1" is located is the first bit. Assuming that the value of the first bit is "1", it means that the first bit indicates that the second signaling is used to indicate the transmission status of the SSB. The first bit indicates that the second signaling is used to indicate the activation or deactivation of the secondary cell and the transmission status of the SSB. Among them, C1 to C7 are secondary cell identifiers, and S1 to S7 are SSB transmission status indication fields corresponding to each secondary cell.

[0167] It can be understood that when the first bit indicates that the second signaling is used to indicate the transmission status of the SSB, how to indicate the transmission status of the SSB can be achieved through the second bit, and the second bit is used to indicate the transmission status of the SSB.

[0168] Optionally, the second bit can indicate the transmission status of the SSB in the following manner: the second bit indicates that the transmission status of the SSB corresponding to the secondary cell is turned on, or the transmission status of the SSB corresponding to the secondary cell is turned off, or the second bit indicates that the transmission status of the SSB resource set corresponding to the secondary cell is turned on, or the transmission status of the SSB resource set corresponding to the secondary cell is turned off.

[0169] For ease of understanding, continuing with the embodiment of Figure 2H, the second bit can respectively indicate the transmission status of one or more SSBs in S1 to S7 as shown in Figure 2H. It can also be indicated in the manner of Figure 2I. Figure 2I is a structural diagram of a second signaling according to an embodiment of the present disclosure. As shown in Figure 2I, the position where "1" is located is the first bit. Assuming that the value of the first bit is "1", it means that the first bit indicates that the second signaling is used to indicate the transmission status of the SSB. The first bit indicates that the second signaling is used to indicate the activation or deactivation of the secondary cell and the transmission status of the SSB. Among them, C1 to C7 are secondary cell identifiers. In the original TRS domain (for example, the information domain represented by Oct1, Oct2...Oct N+1 in the figure), it is multiplexed to indicate the SSB index (index) or SSB resource set identifier (SSB resource set ID), that is, by indicating the resource set identifier, it indicates the on or off status of the SSB resource or SSB resource set of the corresponding secondary cell. In the embodiment of Figure 2I, if the values ​​of C1 to C7 are all 0, only the SSB status is indicated (no cell activation or deactivation indication is performed); if the values ​​of C1 to C7 are not all 0, the activation or deactivation of the secondary cell and the transmission status of the SSB can be indicated at the same time.

[0241] Figure 5 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 5, the embodiment of the present disclosure relates to a communication method, which includes:

[0242] Step S5101, sending instruction information.

[0243] In some embodiments, the indication information is used to indicate the transmission status of the SSB, where the transmission status includes an on state or an off state.

[0244] The optional implementation of step S5101 can refer to the optional implementation of step S2101, step S2102, step S2103 in Figure 2A, as well as other related parts in the embodiment involved in Figure 2A, which will not be repeated here.

[0245] In some embodiments, the above method may also include the methods described in the above embodiments such as the communication system side, the terminal side, and the network device side, which will not be repeated here.

[0246] In some embodiments, the present disclosure also proposes a communication method that indicates to users the start or stop status of SSB transmission while also supporting rapid SSB-based Scell ​​activation. Based on the SSB status indication, users can determine their own behavior to reduce unnecessary resource usage and power consumption caused by invalid measurements and reporting. This also reduces Scell ​​activation latency, allowing the activated Scell ​​to provide users with higher transmission rates as quickly as possible.

[0247] In some embodiments, when the secondary cell of the terminal supports network energy saving (NES) of on-demand SSB technology, it can be achieved in the following ways:

[0248] -a) The terminal receives the activation or activation signaling of the Scell ​​to determine the on or off state of the SSB.

[0249] -b) The terminal receives the newly introduced indication signaling and determines whether the SSB is in the off or on state, and / or the activation or deactivation state of the Scell.

[0250] Regarding -a), its implementation methods include -a1) and -a2):

[0251] -a1): After the user receives the Scell ​​activation signaling, the SSB is turned on for at least N cycles, where N is an integer greater than or equal to 1.

[0252] Optionally, the on-time is specified by a protocol or indicated by a network.

[0253] Optionally, after receiving the Scell ​​activation signaling, the user starts receiving SSBs for synchronization and automatic power gain control.

[0254] In this embodiment, after the user completes Scell ​​activation for N SSB cycles, or after receiving Scell ​​deactivation signaling, the start or shutdown state of the SSB is completely determined by the network side. The user determines the start or shutdown state of the SSB by receiving the first indication signaling or receiving the reference signal. The first indication information can be a signaling that explicitly indicates the SSB state to the user, and the reference signal can be a DRS or an SSB, which is not limited in this embodiment (for descriptions of related embodiments, please refer to the description of the related embodiments in Figure 2B, which will not be repeated here).

[0255] -a2): The user receives the activation and deactivation signaling of the Scell ​​to determine the transmission status of the SSB.

[0256] Optionally, the user receives activation signaling of the Scell ​​and determines that the network enables SSB.

[0257] Optionally, the user receives a deactivation of the scell and determines that the network has shut down the SSB.

[0258] Optionally, the user performs layer 3 (L3) measurement based on the CSI-RS of the scell.

[0259] In this embodiment, the user receives activation and deactivation signaling from the Scell ​​to determine the transmission state of the SSB. When the user receives activation signaling from the Scell, it determines that the network has started SSB; when the user receives deactivation signaling from the Scell, it determines that the network has shut down SSB. (For related embodiments, please refer to the description of the related embodiment in Figure 2C, which will not be repeated here.)

[0260] For b), the user receives network indication information, which is used to indicate to the user whether the SSB is in the off or on state and / or the activation / deactivation state of the Scell. The indication information can be DCI, MAC CE, or RRC signaling, or it can reuse existing Scell ​​activation / deactivation signaling.

[0261] Optionally, the indication information may be used to indicate the SSB state, or to activate / deactivate the scell, or to indicate the SSB state and activate / deactivate the scell at the same time.

[0262] Optionally, the information includes at least a first indication field, which is used to indicate: the signaling is used to indicate the SSB status; or the signaling is used to activate / deactivate the scell; or the signaling is used to simultaneously indicate the SSB status and activate / deactivate the scell.

[0263] Optionally, the information may further include a second indication field, which is used to indicate the identifier of the activated scell.

[0264] Optionally, the information may also include a third indication field for indicating whether the SSB status is on or off.

[0265] In this embodiment, the indication information can be used to indicate the SSB state, or to activate / deactivate a scell, or to indicate both the SSB state and the activation / deactivation of a scell. The information includes at least a first indication field, which is used to indicate: the signaling is used to indicate the SSB state; or the signaling is used to activate / deactivate a scell; or the signaling is used to simultaneously indicate the SSB state and the activation / deactivation of a scell; the information includes a second indication field, which is used to indicate the identifier of the scell to be activated; the information includes a third indication field, which is used to indicate whether the SSB state is on or off (for descriptions of relevant embodiments, please refer to FIG. 2D and the descriptions of the relevant embodiments in FIG. 2E, which will not be repeated here).

[0266] In some embodiments, in the -b) scheme, the terminal receives indication information from the network, and the indication information is used to indicate to the user whether the SSB is in the closed or started state and / or the activation / deactivation state of the scell. The indication information reuses the existing fast scell activation / deactivation signaling. The reserved bit R is used to indicate the purpose of the activation / deactivation signaling. If the bit is 0, it is an existing function; if it is 1, it is used for the status indication of the SSB or the SSB-based scell activation. It can indicate the start or close of the SSB of the corresponding scell. It can also indicate the opening or closing of an ssb resource set for each scell, where each SSB resource set can contain one or more SSB indexes of the scell (for descriptions of relevant embodiments, please refer to Figures 2F and 2G, which are not repeated here).

[0267] When the reserved bit R takes the value of 1, C1-C7 is still used to activate / deactivate the corresponding scell; the subsequent TRS domain is reused to indicate the SSB Index, or SSB Resource Set Id. 1 bit can be used to indicate the start or end of the SSB of the corresponding scell. It can also indicate the opening or closing of an ssb resource set for each scell. Among them, or the opening and closing status of each SSB resource set. Si or resource set Idi corresponds to the scell in the preconfigured scell list (for descriptions of relevant embodiments, please refer to the descriptions of relevant embodiments in Figure 2H, which will not be repeated here). Optionally, if C1-C7 are all 0, only the SSB state is indicated; if not all 0, the scell is activated / deactivated at the same time, and the opening or closing of the SSB of the scell is indicated.

[0268] In some embodiments, network devices can decide whether to enable or disable SSB based on their energy-saving needs. When the network decides to enable or disable SSB, it uses indication signaling to indicate the SSB on or off status to the user. The indication signaling may be the signaling described in -a1), -a2), and -b).

[0269] In some embodiments, the network instructs the user to enable SSB via SSB activation / deactivation signaling. The network deactivates SSB as needed. After deactivating SSB, the network receives a WUS signal sent by the user. The WUS signal can be specific sequence information or predefined MAC CE or RRC signaling, which is not limited in this embodiment. The network preconfigures receiving resources for the user. After receiving the WUS signal, the network independently determines whether to enable SSB. If it decides to enable SSB, it provides feedback to the user via Scell ​​activation or deactivation signaling confirming that SSB will be enabled. This signaling can be the signaling mentioned in b).

[0270] The disclosed embodiments can indicate the start or stop status of SSB to users and support rapid SSB-based Scell ​​activation. Users can determine their behavior based on the SSB status indication to reduce unnecessary resource usage and power consumption caused by invalid measurements and reporting. This also reduces Scell ​​activation latency, allowing the activated Scell ​​to provide users with higher transmission rates as quickly as possible.
