Description

A communication method, device and storage medium

[0001] This application claims priority to Chinese Patent Application No. 2025101287295, filed on January 27, 2025, entitled "A Communication Method, Device and Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a communication method, device and storage medium. Background Technology

[0003] In New Radio (NR), Primary Synchronization Signals (PSS), Secondary Synchronization Signals (SSS), and the Physical Broadcast Channel (PBCH) communicate to form a Synchronization Signal Block (SSB). In Carrier Aggregation (CA) scenarios, the Primary Cell (PCell) does not broadcast the SSB; instead, it broadcasts the SSB based on network requests or user equipment (UE) requests.

[0004] In some scenarios, SSBs can be transmitted periodically in the form of SSB bursts / windows. Periodically transmitted SSBs can be called always-on SSBs. On-demand SSBs can be provided during the intervals between SSB bursts / windows when needed. While periodically transmitting SSBs can reduce energy consumption with longer cycles, it impacts performance, such as affecting synchronization / resynchronization / Automatic Gain Control (AGC) latency. Providing on-demand SSBs can improve performance, but the configuration of on-demand SSBs may differ from that of always-on SSBs. Therefore, how to configure on-demand SSBs is a problem that urgently needs to be solved. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a communication method, device, and storage medium capable of configuring relevant configuration information for signal blocks requiring synchronization.

[0006] In a first aspect, this application provides a communication method applied to a terminal device. The method includes: receiving first information, the first information including relevant configuration information of an on-demand synchronization signal block and / or indication information of the relevant configuration information of the on-demand synchronization signal block, the relevant configuration information of the on-demand synchronization signal block including configuration information of the on-demand synchronization signal block and / or SSB measurement timing configuration (SMTC) information of the on-demand synchronization signal block, and the indication information of the relevant configuration information of the on-demand synchronization signal block being used to indicate whether at least one configuration information of the relevant configuration information of the on-demand synchronization signal block exists or is retained.

[0007] Using the above method, the first information carries relevant configuration information of the on-demand synchronization signal block, and / or indication information of the relevant configuration information of the on-demand synchronization signal block. Specifically, when the first information carries relevant configuration information of the on-demand synchronization signal block, the first information can indicate the existence or retention of at least one of the configuration information of the on-demand synchronization signal block and / or the SMTC configuration information of the on-demand synchronization signal block. Based on this first information, the relevant configuration information of the on-demand synchronization signal block can be configured.

[0008] In one possible implementation, the method further includes receiving second information, the second information including activation indication information for on-demand synchronization signal blocks. In this implementation, the second information can indicate whether the on-demand synchronization signal blocks are activated, for example, indicating whether all or part of the on-demand synchronization signal blocks of the secondary cells are activated.

[0009] In one possible implementation, the first and second information are carried in the same signaling message, or they are carried in different signaling messages. When carried in the same signaling message, a single signaling message can indicate whether the on-demand synchronization signal block is active and configure the relevant configuration information for the signal block to be synchronized, reducing the number of signaling messages and improving efficiency.

[0010] In one possible implementation, the on-demand synchronization signal block configuration information includes at least one of the following: SSB configuration identifier, period of the on-demand synchronization signal block, activation time of the on-demand synchronization signal block, number of bursts of the on-demand synchronization signal block, SSB frequency point, subcarrier spacing of the SSB, related power information of the SSB, and SSB burst position indication information.

[0011] In one possible implementation, the SMTC configuration information of the on-demand synchronization signal block includes at least one of the following: the period of the measurement window for receiving the synchronization signal SS and / or the physical broadcast channel PBCH block, the offset of the measurement window for receiving the SS and / or PBCH block, and the duration of the measurement window for receiving the SS and / or PBCH block.

[0012] In one possible implementation, the second information corresponds to one or more secondary cell SCells. In this implementation, the second information may indicate the activation of an on-demand synchronization signal block for one SCell, or indicate the activation of on-demand synchronization signal blocks for multiple SCells.

[0013] In one possible implementation, the method further includes: receiving third information, which is used to configure relevant configuration information of the first SSB. The relevant configuration information of the first SSB includes first SSB configuration information and / or SMTC configuration information of the first SSB. The first SSB is a periodically transmitted SSB. The first SSB can use a longer period to reduce power consumption, and performance is guaranteed by providing additional on-demand synchronization signal blocks. The first SSB is an always-on SSB.

[0014] In one possible implementation, the method further includes receiving fourth information used to activate the secondary cell SCell. In this implementation, the activation information for the SCell is different from the first and second information. However, the fourth and first information can be carried in the same signaling, and / or, the fourth and second information can be carried in the same signaling.

[0015] In one possible implementation, the signaling including the fourth information and the signaling including the second information are identified by different logical channel identifiers (LCIDs) or extended logical channel identifiers (eLCIDs). In this case, the fourth information and the second information are carried in different signaling messages.

[0016] In one possible implementation, the second information and the first information are included in the third signaling; or the second information is included in the third signaling, and the first information is included in the fourth signaling; the third and fourth signaling are identified by different logical channel identifiers (LCIDs) or extended logical channel identifiers (eLCIDs). When the second information and the first information are carried in the same signaling, a single signaling can be used to indicate whether the on-demand synchronization signal block is active and to configure the relevant configuration information of the signal block to be synchronized, reducing the number of signaling messages and improving efficiency.

[0017] In one possible implementation, the fourth signaling also includes cell identification information.

[0018] In one possible implementation, the fourth signaling is also used to instruct the activation of the on-demand synchronization signal block.

[0019] In one possible implementation, the method also includes receiving a fifth piece of information.

[0020] The fifth information is used to indicate the configuration information of at least one set of on-demand synchronization signal blocks. This fifth information is carried in the Radio Resource Control (RRC) signaling. The first information is used to indicate the use of at least one set of configuration information for the on-demand synchronization signal blocks in the fifth information. That is, multiple sets of on-demand SSB configuration information are configured for each cell or all cells in the RRC signaling. The second information is used to indicate which set of on-demand synchronization signal block configuration information in the RRC signaling is used. For example, each set of on-demand SSB configuration information is associated with an index value. The first information is the SSB configuration index value, used to indicate the use of the on-demand SSB configuration information with the index value as the first information. For example, the on-demand SSB configuration information includes SSB configuration information. The RRC signaling configures SSB configuration information 1 / 2 / 3. Each set of configuration information includes at least one of the following: SSB configuration identifier, on-demand SSB period, on-demand SSB activation time, number of on-demand SSB bursts, SSB frequency point, SSB subcarrier spacing, related SSB power information, and SSB burst location indication information. The second information is used to indicate the use of SSB configuration information 1. That is, the terminal device uses configuration information 1 to receive on-demand SSB.

[0021] Alternatively, the fifth information may be used to indicate a list of at least one of the following configuration information related to the on-demand synchronization signal block: SSB configuration identifier list, on-demand synchronization signal block period list, on-demand synchronization signal block activation time list, on-demand synchronization signal block burst count list, SSB frequency point list, SSB subcarrier spacing, and SSB subcarrier spacing list. The first information may be used to indicate at least one of the contents of the list, and the fifth information may be carried in the RRC signaling. That is, the RRC signaling configures a list of on-demand SSB configuration information for each cell or all cells, and the first information may be used to indicate at least one of the contents of the list. For example, the list of on-demand SSB configuration information may be associated with an index value, where the first information is the SSB configuration information index value, used to indicate the configuration information of the on-demand SSB using the index value as the first information. For example, the relevant configuration information for on-demand SSBs includes SSB configuration information, and the list information includes an SSB configuration identifier list, an on-demand SSB period list, an on-demand SSB activation time list, an on-demand SSB burst count list, an SSB frequency point list, and an SSB subcarrier spacing list. For example, the on-demand SSB period list shows RRC signaling configured with 20ms, 40ms, and 80ms SSB periods. The second piece of information indicates the use of the first SSB period. That is, the terminal device uses an SSB period of 20ms to receive on-demand SSBs.

[0022] In one possible implementation, the method further includes: using the content of the first information. That is, if the first information includes specific on-demand synchronization signal block configuration information and / or SMTC configuration information of the on-demand synchronization signal block, the terminal device can use the acquired information to configure the on-demand synchronization signal block.

[0023] In one possible implementation, the configuration information related to the on-demand synchronization signal block includes on-demand synchronization signal block configuration information, and the indication information of the configuration information includes first indication information. The first indication information is the SSB period of the on-demand synchronization signal block configuration information. When the SSB period is a first value, it indicates that at least one item of the on-demand synchronization signal block configuration information is reserved or does not exist.

[0024] In this implementation, the network device does not configure the on-demand SSB through the first information configuration. For example, it can use the content pre-configured by Radio Resource Control (RRC) signaling. In this case, the period field of the on-demand synchronization signal block configuration information can be used to indicate whether at least one item of the on-demand synchronization signal block configuration information is reserved or does not exist.

[0025] In one possible implementation, the relevant configuration information of the on-demand synchronization signal block includes the SMTC configuration information of the on-demand synchronization signal block, and the indication information of the relevant configuration information of the on-demand synchronization signal block includes second indication information; the second indication information is the period of the measurement window of the received synchronization signal SS and / or physical broadcast channel PBCH block of the SMTC configuration information of the on-demand synchronization signal block, and when the period of the measurement window of the received SS and / or PBCH block is a first value, it indicates that at least one item of the SMTC configuration information of the on-demand synchronization signal block is reserved or does not exist.

[0026] In this implementation, the network device does not configure the SMTC configuration information of the on-demand SSB through the first information. For example, the content pre-configured by the Radio Resource Control signaling can be used. At this time, the period field of the SMTC configuration information of the on-demand synchronization signal block can be used to indicate whether at least one item of the SMTC configuration information of the on-demand synchronization signal block is reserved or does not exist.

[0027] In one possible implementation, the configuration information related to the on-demand synchronization signal block includes on-demand synchronization signal block configuration information, and the indication information of the configuration information includes third indication information. The third indication information is used to indicate whether at least one item in the on-demand synchronization signal block configuration information exists or is reserved. For example, the third indication information can use a one-bit value to indicate whether the content of an on-demand synchronization signal block configuration information exists or is reserved.

[0028] In one possible implementation, the configuration information related to the on-demand synchronization signal block includes the SMTC configuration information of the on-demand synchronization signal block, and the indication information of the configuration information includes fourth indication information. The fourth indication information is used to indicate whether at least one item in the SMTC configuration information of the on-demand synchronization signal block exists or is reserved. For example, the fourth indication information can use a one-bit value to indicate whether the content of the SMTC configuration information of an on-demand synchronization signal block exists or is reserved.

[0029] In one possible implementation, the signaling including the second information is either a first signaling or a second signaling. The first signaling is used to indicate the activation of on-demand synchronization signal blocks for up to seven cells, and the second signaling indicates the activation of on-demand synchronization signal blocks for up to 31 cells. The first and second signaling are identified by different Logical Channel Identifiers (LCIDs) or Extended Logical Channel Identifiers (eLCIDs).

[0030] In one possible implementation, the third indication information corresponds to all secondary cell SCells that activate on-demand synchronization signal blocks in the first signaling including the second information; or the third indication information corresponds to one secondary cell SCell that activates on-demand synchronization signal blocks in the first signaling including the second information.

[0031] In this implementation, the third indication information indicates whether at least one item in the configuration information of the on-demand synchronization signal block of each SCell activating the on-demand synchronization signal block in the first signaling exists or is reserved.

[0032] In one possible implementation, the fourth indication information corresponds to all secondary cell SCells that activate on-demand synchronization signal blocks in the first signaling including the second information; or the fourth indication information corresponds to one secondary cell SCell that activates on-demand synchronization signal blocks in the first signaling including the second information.

[0033] The fourth indication information corresponds to the secondary cell SCell that activates on-demand SSB in the first signaling including the second information; or the third indication information indicates whether at least one item in the SMTC configuration information of the on-demand SSB of each SCell that activates on-demand SSB in the first signaling exists or is reserved.

[0034] In one possible implementation, the activation indication information of the on-demand synchronization signal block is also used to activate or deactivate the secondary cell (SCell). That is, the first information can be used to activate or deactivate the secondary cell, achieving functional reuse and eliminating the need for additional information to activate or deactivate the secondary cell.

[0035] In one possible implementation, the second information includes an on-demand indicator, which indicates whether the activation indication information of the on-demand synchronization signal block is also used to activate the SCell, or whether the on-demand synchronization signal block of an already activated SCell is activated simultaneously. The on-demand indicator can achieve the corresponding indication function through the value of a single bit.

[0036] In one possible implementation, the method further includes: when it is determined that there is a first unconfigured content in the relevant configuration information of the on-demand synchronization signal block, determining the first unconfigured content based on the relevant configuration information of at least one set of on-demand synchronization signal blocks indicated by the fifth information, wherein the first unconfigured content includes unconfigured content of the configuration information of the on-demand synchronization signal block and / or unconfigured content of the SMTC configuration information of the on-demand synchronization signal block, and the fifth information is carried in the RRC signaling.

[0037] In one possible implementation, the method further includes: sending a first request, the first request being used to request the transmission of first configuration information, the first configuration information including at least one configuration information related to on-demand synchronization signal blocks, the first request being carried in Radio Resource Control (RRC) signaling, or in Media Access Control (MAC) CE, or in Uplink Control Information (UCI).

[0038] In this implementation, when the fifth information does not include all of the first unconfigured content, a first request is sent. The first request is used to request the sending of the second unconfigured content. The second unconfigured content does not include the configuration content included in the fifth information of the first unconfigured content. The first request is carried in the Radio Resource Control (RRC) signaling, or in the Media Access Control (MAC) CE, or in the Uplink Control Information (UCI).

[0039] In one possible implementation, the method further includes: receiving sixth information, which includes the first configuration information; the sixth information is carried in RRC signaling, or in MAC CE, or in downlink control information (DCI).

[0040] In one possible implementation, the method further includes: using the SMTC configuration information of the first SSB when the SMTC configuration information of the on-demand synchronization signal block is not configured; or, using the SMTC configuration information of the pre-received on-demand synchronization signal block when there is pre-received SMTC configuration information of the on-demand synchronization signal block and the received SMTC configuration information of the on-demand synchronization signal block has no unconfigured content; or, using the SMTC configuration information of the first SSB when there is no SMTC configuration information of the on-demand synchronization signal block and the SMTC configuration information of the first SSB exists.

[0041] In one possible implementation, the method further includes: using the SSB configuration information of the first SSB when the SSB configuration information of the on-demand synchronization signal block is not configured; or, using the pre-received SSB configuration information of the on-demand synchronization signal block when there is pre-received SSB configuration information of the on-demand synchronization signal block and the received SSB configuration information of the on-demand synchronization signal block has no unconfigured content; or, using the SSB configuration information of the first SSB when there is no SSB configuration information of the on-demand synchronization signal block and the SSB configuration information of the first SSB exists.

[0042] In one possible implementation, the signaling carrying the second information and / or the first information further includes a fifth indication information, which is used to indicate whether the SMTC configuration information of the first SSB is used or to indicate whether the SSB configuration of the first SSB is used.

[0043] In one possible implementation, the method further includes: the fifth indication information instructing the use of the configuration information of the first SSB when at least one configuration information of the SMTC configuration information and / or at least one configuration information of the SSB configuration information of the on-demand synchronization signal block is absent; or, when at least one configuration information of the SMTC configuration information and / or at least one configuration information of the SSB configuration information of the on-demand synchronization signal block configured by the second signaling is absent, and at least one configuration information of the SMTC configuration information and / or at least one configuration information of the SSB configuration information of the first SSB is also absent, a first request is sent; or, the fifth indication information instructing the use of the configuration information of the first SSB when at least one configuration information of the SMTC configuration information of the on-demand synchronization signal block is absent. If at least one configuration information and / or SSB configuration information is missing, the configuration information of the first SSB is not used. If at least one configuration information and / or at least one configuration information of the SMTC configuration information and / or SSB configuration information of the on-demand synchronization signal block configured by the second signaling is missing, a first request is sent. Alternatively, the fifth indication information indicates that if at least one configuration information and / or at least one configuration information of the SMTC configuration information and / or SSB configuration information of the on-demand synchronization signal block is missing, the configuration information of the first SSB is not used. If at least one configuration information and / or at least one configuration information of the SMTC configuration information and / or SSB configuration information is missing, a first request is sent.

[0044] In this implementation, the fifth indication information indicates that when the SMTC configuration information of the on-demand synchronization signal block is missing, the SMTC configuration of the first SSB is used; when there is no pre-received SMTC configuration information of the on-demand synchronization signal block and no pre-received SMTC configuration information of the always-on SSB, the first unconfigured content is determined to include the unconfigured content of the SMTC configuration information of the on-demand synchronization signal block; or, the fifth indication information indicates that when the SMTC configuration information of the on-demand synchronization signal block is missing, the SMTC configuration of the first SSB is not used; when there is no pre-received SMTC configuration information of the on-demand synchronization signal block, the first unconfigured content is determined to include the unconfigured content of the SMTC configuration information of the on-demand synchronization signal block; or, the fifth indication information indicates that when the SMTC configuration information of the on-demand synchronization signal block is missing, the SMTC configuration of the always-on SSB is not used; and when there is third unconfigured content in the pre-received SMTC configuration information of the on-demand synchronization signal block, the first unconfigured content is determined to include the third unconfigured content.

[0046] Using the above method, the first information carries activation indication information for the on-demand synchronization signal blocks. Based on this first information, it indicates whether the on-demand synchronization signal blocks are activated, for example, whether all or part of the on-demand synchronization signal blocks of the secondary cells are activated. Then, the on-demand synchronization signal blocks are received according to the first configuration information to realize the configuration of the on-demand synchronization signal blocks.

[0047] In one possible implementation, the configuration information of the on-demand synchronization signal block is configured by a first signaling, and the configuration information of the on-demand synchronization signal block's SMTC is configured by a second signaling; the first signaling and the second signaling are the same signaling, or the first signaling and the second signaling are different signaling; the first signaling and the second signaling are one of the following: Radio Resource Control (RRC) signaling, Media Access Control Unit (MAC CE), and Downlink Control Information (DCI).

[0053] In one possible implementation, the signaling carrying the first information further includes a fifth indication information, or the first information further includes a fifth indication information, the fifth indication information being used to indicate whether the SSB configuration information and / or SMTC configuration information of the first SSB are used.

[0054] In one possible implementation, the method further includes: the fifth indication information instructing the use of the configuration information of the first SSB when at least one configuration information of the SMTC configuration information and / or at least one configuration information of the SSB configuration information of the on-demand synchronization signal block is absent; or, when at least one configuration information of the SMTC configuration information and / or at least one configuration information of the SSB configuration information of the on-demand synchronization signal block configured by the second signaling is absent, and at least one configuration information of the SMTC configuration information and / or at least one configuration information of the SSB configuration information of the first SSB is also absent, a first request is sent; or, the fifth indication information instructing the use of the configuration information of the first SSB when at least one configuration information of the SMTC configuration information of the on-demand synchronization signal block is absent. If at least one configuration information and / or SSB configuration information is missing, the configuration information of the first SSB is not used. If at least one configuration information and / or at least one configuration information of the SMTC configuration information and / or SSB configuration information of the on-demand synchronization signal block configured by the second signaling is missing, a first request is sent. Alternatively, the fifth indication information indicates that if at least one configuration information and / or at least one configuration information of the SMTC configuration information and / or SSB configuration information of the on-demand synchronization signal block is missing, the configuration information of the first SSB is not used.

[0056] In this implementation, third information can be used to indicate whether the on-demand synchronization signal block is activated, for example, to indicate whether the on-demand synchronization signal blocks of all or part of the secondary cells are activated.

[0057] In one possible implementation, one or more cells are secondary cells (SCells).

The configuration information related to the on-demand synchronization signal block includes configuration information of the on-demand synchronization signal block and / or SSB measurement timing configuration (SMTC) information of the on-demand synchronization signal block. The indication information of the configuration information related to the on-demand synchronization signal block is used to indicate whether at least one configuration information of the configuration information related to the on-demand synchronization signal block exists or is retained.

[0064] In one possible implementation, the method further includes sending second information, which includes activation indication information for on-demand synchronization signal blocks. In this implementation, the second information can indicate whether the on-demand synchronization signal blocks are activated, for example, indicating whether all or some of the on-demand synchronization signal blocks of the secondary cells are activated.

[0065] In one possible implementation, the first and second information are carried in the same signaling message, or they are carried in different signaling messages. When carried in the same signaling message, a single signaling message can indicate whether the on-demand synchronization signal block is active and configure the relevant configuration information for the signal block to be synchronized, reducing the number of signaling messages and improving efficiency.

[0066] In one possible implementation, the on-demand synchronization signal block configuration information includes at least one of the following: SSB configuration identifier, period of the on-demand synchronization signal block, activation time of the on-demand synchronization signal block, number of bursts of the on-demand synchronization signal block, SSB frequency point, subcarrier spacing of the SSB, related power information of the SSB, and SSB burst position indication information.

[0068] In one possible implementation, the second information corresponds to one or more secondary cell SCells. In this implementation, the second information may indicate the activation of an on-demand synchronization signal block for one SCell, or indicate the activation of on-demand synchronization signal blocks for multiple SCells.

[0069] In one possible implementation, the method further includes: sending third information, which is used to configure relevant configuration information of the first SSB. The relevant configuration information of the first SSB includes first SSB configuration information and / or SMTC configuration information of the first SSB. The first SSB is a periodically transmitted SSB. The first SSB can use a longer period to reduce power consumption, and performance can be guaranteed by providing additional on-demand synchronization signal blocks.

[0070] In one possible implementation, a fourth message is sent to activate the secondary cell (SCell). In this implementation, the SCell activation information is different from the first and second messages. However, the fourth and first messages can be carried in the same signaling, and / or, the fourth and second messages can be carried in the same signaling.

[0071] In one possible implementation, the signaling including the fourth information and the signaling including the second information are identified by different logical channel identifiers (LCIDs) or extended logical channel identifiers (eLCIDs). In this case, the fourth information and the second information are carried in different signaling messages.

[0072] In one possible implementation, the second information and the first information are included in the third signaling; or the second information is included in the third signaling, and the first information is included in the fourth signaling; the third and fourth signaling are identified by different logical channel identifiers (LCIDs) or extended logical channel identifiers (eLCIDs). When the second information and the first information are carried in the same signaling, a single signaling can be used to indicate whether the on-demand synchronization signal block is active and to configure the relevant configuration information of the signal block to be synchronized, reducing the number of signaling messages and improving efficiency.

[0073] In one possible implementation, the fourth signaling also includes cell identification information.

[0074] In one possible implementation, the fourth signaling is also used to instruct the activation of the on-demand synchronization signal block.

[0075] In one possible implementation, the method also includes sending a fifth message.

[0076] The fifth information is used to indicate the configuration information of at least one set of on-demand synchronization signal blocks. This fifth information is carried in the Radio Resource Control (RRC) signaling. The first information is used to indicate the use of at least one set of configuration information for the on-demand synchronization signal blocks in the fifth information. That is, multiple sets of on-demand SSB configuration information are configured for each cell or all cells in the RRC signaling. The second information is used to indicate which set of on-demand synchronization signal block configuration information in the RRC signaling is used. For example, each set of on-demand SSB configuration information is associated with an index value. The first information is the SSB configuration index value, used to indicate the use of the on-demand SSB configuration information with the index value as the first information. For example, the on-demand SSB configuration information includes SSB configuration information. The RRC signaling configures SSB configuration information 1 / 2 / 3. Each set of configuration information includes at least one of the following: SSB configuration identifier, on-demand SSB period, on-demand SSB activation time, number of on-demand SSB bursts, SSB frequency point, SSB subcarrier spacing, related SSB power information, and SSB burst location indication information. The second information is used to indicate the use of SSB configuration information 1. That is, the terminal device uses configuration information 1 to receive on-demand SSB.

[0077] Alternatively, the fifth information may be used to indicate a list of at least one of the following configuration information related to the on-demand synchronization signal block: SSB configuration identifier list, on-demand synchronization signal block period list, on-demand synchronization signal block activation time list, on-demand synchronization signal block burst count list, SSB frequency point list, SSB subcarrier spacing, and SSB subcarrier spacing list. The first information may be used to indicate at least one of the contents of the list, and the fifth information may be carried in the RRC signaling. That is, the RRC signaling configures a list of on-demand SSB configuration information for each cell or all cells, and the first information may be used to indicate at least one of the contents of the list. For example, the list of on-demand SSB configuration information may be associated with an index value, where the first information is the SSB configuration information index value, used to indicate the configuration information of the on-demand SSB using the index value as the first information. For example, the relevant configuration information for on-demand SSBs includes SSB configuration information, and the list information includes an SSB configuration identifier list, an on-demand SSB period list, an on-demand SSB activation time list, an on-demand SSB burst count list, an SSB frequency point list, and an SSB subcarrier spacing list. For example, the on-demand SSB period list shows RRC signaling configured with 20ms, 40ms, and 80ms SSB periods. The second piece of information indicates the use of the first SSB period. That is, the terminal device uses an SSB period of 20ms to receive on-demand SSBs.

[0078] In one possible implementation, the configuration information related to the on-demand synchronization signal block includes on-demand synchronization signal block configuration information, and the indication information of the configuration information includes first indication information. The first indication information is the SSB period of the on-demand synchronization signal block configuration information. When the SSB period is a first value, it indicates that at least one item of the on-demand synchronization signal block configuration information is reserved or does not exist.

[0079] In one possible implementation, the relevant configuration information of the on-demand synchronization signal block includes the SMTC configuration information of the on-demand synchronization signal block, and the indication information of the relevant configuration information of the on-demand synchronization signal block includes second indication information; the second indication information is the period of the measurement window of the received synchronization signal SS and / or physical broadcast channel PBCH block of the SMTC configuration information of the on-demand synchronization signal block, and when the period of the measurement window of the received SS and / or PBCH block is a first value, it indicates that at least one item of the SMTC configuration information of the on-demand synchronization signal block is reserved or does not exist.

[0080] In one possible implementation, the configuration information related to the on-demand synchronization signal block includes on-demand synchronization signal block configuration information, and the indication information of the configuration information includes third indication information. The third indication information is used to indicate whether at least one item in the on-demand synchronization signal block configuration information exists or is reserved. For example, the third indication information can use a one-bit value to indicate whether the content of an on-demand synchronization signal block configuration information exists or is reserved.

[0081] In one possible implementation, the configuration information related to the on-demand synchronization signal block includes the SMTC configuration information of the on-demand synchronization signal block, and the indication information of the configuration information includes fourth indication information. The fourth indication information is used to indicate whether at least one item in the SMTC configuration information of the on-demand synchronization signal block exists or is reserved. For example, the fourth indication information can use a one-bit value to indicate whether the content of the SMTC configuration information of an on-demand synchronization signal block exists or is reserved.

[0082] In one possible implementation, the signaling including the second information is either a first signaling or a second signaling. The first signaling is used to indicate the activation of on-demand synchronization signal blocks for up to seven cells, and the second signaling indicates the activation of on-demand synchronization signal blocks for up to 31 cells. The first and second signaling are identified by different Logical Channel Identifiers (LCIDs) or Extended Logical Channel Identifiers (eLCIDs).

[0083] In one possible implementation, the third indication information corresponds to all secondary cell SCells that activate on-demand synchronization signal blocks in the first signaling including the second information; or the third indication information corresponds to one secondary cell SCell that activates on-demand synchronization signal blocks in the first signaling including the second information.

[0084] In one possible implementation, the fourth indication information corresponds to all secondary cell SCells that activate on-demand synchronization signal blocks in the first signaling including the second information; or the fourth indication information corresponds to one secondary cell SCell that activates on-demand synchronization signal blocks in the first signaling including the second information.

[0085] In one possible implementation, the activation indication information of the on-demand synchronization signal block is also used to activate or deactivate the secondary cell (SCell). That is, the first information can be used to activate or deactivate the secondary cell, achieving functional reuse and eliminating the need for additional information to activate or deactivate the secondary cell.

[0086] In one possible implementation, the second information includes an on-demand indicator, which indicates whether the activation indication information of the on-demand synchronization signal block is also used to activate the SCell, or whether the on-demand synchronization signal block of an already activated SCell is activated simultaneously. The on-demand indicator can achieve the corresponding indication function through the value of a single bit.

[0087] In one possible implementation, a first request is received, the first request being used to request the transmission of first configuration information, the first configuration information including at least one configuration information related to the on-demand synchronization signal block, the first request being carried in Radio Resource Control (RRC) signaling, or in Media Access Control (MAC) CE, or in Uplink Control Information (UCI).

[0088] In one possible implementation, a sixth message is sent, which includes the first configuration information; the sixth message is carried in RRC signaling, or in MAC CE, or in downlink control information (DCI).

[0089] Sixthly, this application also provides a communication method applied to a network device. The method includes: sending first information, wherein the first information includes activation indication information for an on-demand synchronization signal block; and sending sixth information upon receiving a first request. The first request is carried in Radio Resource Control (RRC) signaling, or in Media Access Control (MAC) CE, or in Uplink Control Information (UCI). The terminal device sends the first request when it determines that first configuration information is not configured. The sixth information includes the first configuration information.

[0090] In one possible implementation, the sixth information is carried in the RRC signaling, or in the MAC CE, or in the downlink control information (DCI).

[0091] In one possible implementation, the first information corresponds to one or more secondary cell SCells.

[0092] In one possible implementation, the activation indication information of the on-demand synchronization signal block is also used to activate or deactivate the secondary cell SCell.

[0097] In one possible implementation, the third information also includes a fifth instruction, which is used to indicate the activation or deactivation of individual cells in one or more cells.

[0098] In one possible implementation, the third information also includes an on-demand indication, which is used to indicate whether the activation indication information of the on-demand synchronization signal block is also used to activate the SCell, or to indicate whether the on-demand synchronization signal block of the already activated SCell is activated at the same time.

Unless otherwise specified, the terms "first" and "second" in different embodiments are used to independently distinguish and describe the corresponding embodiments.

[0133] See Figure 1, which is a schematic diagram of a communication system provided in this application.

[0134] The communication system includes network equipment and terminal equipment. The method provided in this application can be applied to cellular communication systems related to the 3rd Generation Partnership Project (3GPP), such as 4th generation (4G) communication systems, such as Long Term Evolution (LTE) communication systems, and also to 5th generation (5G) communication systems. th5G communication systems, such as 5G New Radio (NR) communication systems, or various future communication systems, such as 6th generation (6G) communication systems.

In this application, terminal devices with wireless transceiver capabilities and chips that can be installed in the aforementioned terminal devices are collectively referred to as terminal devices.

[0139] It should be noted that the terminal device may be a device or apparatus with a chip, or a device or apparatus with integrated circuitry, or a chip, module or control unit in the device or apparatus shown above. This application does not limit the specific device.

[0140] The following section first describes the current status of on-demand SSB transmission.

[0141] See Figure 2, which is a schematic diagram of the scenario provided in this application.

[0142] In the diagram, the secondary cell (SCell) is configured at time T1. Between T1 and T2, the secondary cell is configured but not activated. At time T2, the UE receives the SCell activation command. Between T2 and T3, the UE will activate the SCell. At time T3, the SCell activation is complete, and normal data transmission can be performed in the cell.

[0143] Figure 2 illustrates an example where on-demand SSB triggering occurs between T1 and T2. However, on-demand SSB triggering can also occur at time T2. In one implementation, on-demand SSB can also be activated after T3. In this scenario, there is no always-on SSB in the cell; after on-demand SSB is triggered, SSBs are sent periodically.

[0144] See Figure 3, which is a schematic diagram of the scenario provided in this application.

[0145] SSB (also known as always-on SSB) is transmitted periodically in the form of SSB bursts / windows. Additional on-demand SSBs can be provided during the intervals between SSB bursts / windows when needed, or on-demand SSBs with shorter periods than regular SSBs can be provided. Periodic transmissions can reduce energy consumption with longer periods, but this can impact performance, such as affecting synchronization / resynchronization / AGC latency. On-demand SSBs can improve performance.

[0146] For the scenario shown in Figure 3, since the cycles of always-on SSB and on-demand SSB are not necessarily the same, two sets of SSB measurement timing configurations (SMTC) need to be configured for measurement, one for always-on SSB and the other for on-demand SSB.

[0147] While always-on SSB measurements can be performed based on SMTC, how to properly configure the relevant configuration information for on-demand SSB is a problem that urgently needs to be solved.

[0148] To address the above technical problems, this application provides a communication method, device, and storage medium capable of configuring on-demand SSB related configuration information. The on-demand SSB related configuration information may include on-demand SSB configuration information and / or on-demand SSB SMTC configuration information. The implementation of the technical solution of this application is described in detail below with reference to the accompanying drawings.

[0149] Referring to Figure 4A, this figure is a flowchart of a communication method provided in an embodiment of this application.

[0150] The method includes the following steps:

[0151] S1: Receive the first message sent by the network device.

[0152] S2: Complete the relevant configuration of the on-demand SSB based on the first information.

[0153] The first information in this application embodiment includes configuration information related to on-demand SSB and indication information related to on-demand SSB configuration information.

[0154] The configuration information related to the on-demand SSB includes the on-demand SSB configuration information and / or the on-demand SSB SMTC configuration information. The indication information of the on-demand SSB configuration information is used to indicate whether at least one of the configuration information related to the on-demand SSB exists or is retained.

[0155] When always-on SSB configuration information is configured, on-demand SSB configuration information can reuse always-on SSB configuration information, update one or more of always-on SSB configuration information, or completely update always-on SSB configuration information.

[0156] In one possible implementation, the indication information of the relevant configuration information of on-demand SSB indicates whether the SMTC configuration information of on-demand SSB exists or is retained. In this case, the on-demand SSB configuration information can reuse the always-on SSB configuration information. If the always-on SSB configuration information is not configured and the on-demand SSB configuration information is not currently saved, the UE can request the network device to send the on-demand SSB configuration information.

[0157] When SMTC is configured for always-on SSB, the SMTC configuration information for on-demand SSB can reuse the SMTC configuration information for always-on SSB, or update one or more of the SMTC configuration information for always-on SSB, or completely update the SMTC configuration information for always-on SSB.

[0158] In one possible implementation, the indication information of the relevant configuration information of the on-demand SSB indicates whether the on-demand SSB configuration information exists or is retained. In this case, the SMTC configuration information of the on-demand SSB can reuse the SMTC configuration information of the always-on SSB. If the SMTC of the always-on SSB is configured and the SMTC configuration information of the on-demand SSB is not currently saved, the UE can request the network device to send the SMTC configuration information of the always-on SSB.

[0159] Using the solution provided in the embodiments of this application, the UE can perform on-demand SSB configuration based on the first information by carrying the relevant configuration information of on-demand SSB, that is, carrying on-demand SSB configuration information and / or on-demand SSB SMTC configuration information.

[0160] In another possible implementation, the terminal device may also send a second message to the UE to indicate whether the on-demand SSB is activated, as described below with reference to the accompanying drawings.

[0161] Referring to Figure 4B, this figure is a flowchart of another communication method provided in an embodiment of this application.

[0162] The method includes the following steps:

[0163] S11: Receive the first and second information sent by the network device.

[0164] S12: Complete the relevant configuration of the on-demand SSB based on the first and second information.

[0165] For details regarding the first information, please refer to the corresponding explanation in Figure 4A, which will not be repeated here.

[0166] The second piece of information includes activation indication information for the on-demand SSB. This activation indication information can be used to indicate whether the on-demand SSB is activated, for example, indicating whether the on-demand SSB of all or some secondary cells is activated.

[0167] It is understood that the first and second information can be carried in the same signaling message and sent together, or they can be carried in different signaling messages and sent separately. This application embodiment does not make a specific limitation. When the first and second information are carried in different signaling messages and sent separately, this application embodiment does not make a specific limitation on the sending order of the first and second information.

[0168] Using the solution provided in the embodiments of this application, the network device can not only configure the relevant configuration information of on-demand SSB, but also indicate whether on-demand SSB is activated through the second information, thus achieving a more comprehensive indication.

[0169] The implementation methods of the first and second information are explained in detail below.

[0170] The on-demand SSB configuration information in this application embodiment may include one or more of the following: SSB configuration identifier, on-demand SSB period, on-demand SSB activation time, on-demand SSB burst number, SSB frequency point, SSB subcarrier spacing, SSB related power information, and SSB burst location indication information.

[0171] The SSB configuration identifier is used to represent the configuration information of a set of SSBs.

[0172] The on-demand SSB period is used to indicate the on-demand SSB transmission period.

[0173] The activation time of the on-demand SSB is used to indicate the duration of the on-demand SSB transmission, i.e., the duration of the transmission.

[0174] Number of bursts in on-demand SSB: Indicates the number of bursts transmitted by the on-demand SSB. Each burst can include the transmission of multiple SSBs. For example, a burst may include 4 SSBs, denoted as SSB#0, SSB#1, SSB#2, and SSB#3. Each SSB period includes one burst. The number of bursts can also be called the number of periods. For example, if the period is 20ms and the number of bursts is 5, then the on-demand SSB will send 5 bursts, i.e., continuously transmit for 100ms.

[0175] The SSB frequency point is used to indicate the transmission frequency of the SSB reference signal.

[0176] Subcarrier spacing (SCS) of an SSB; used to indicate the subcarrier spacing of an SSB. For example, the subcarrier spacing for Frequency Range 1 (FR1) is 15 kHz or 30 kHz; the subcarrier spacing for FR2-1 is 120 kHz or 240 kHz; and the subcarrier spacing for FR2-2 is 120 kHz, 480 kHz, or 960 kHz.

[0177] SSB related power information: the average energy per resource element (EPRE) of the resource element carrying the auxiliary synchronization signal used by the network for SSB transmission, in dBm.

[0178] SSB Burst Position Indication: This information indicates the location of a transmitted SSB. Specifically, it indicates the temporal location of an SSB transmitted within a half-frame that includes the SSB. The SSB Burst Position Indication is a bitmap indicator; the first bit, or the leftmost bit, indicates SSB (SS / PBCH block) index 0, the second bit indicates SSB (SS / PBCH block) index 1, and so on. The bitmap can contain 4, 8, or 64 bits.

[0179] The SMTC configuration information for on-demand SSB includes at least one of the following:

[0180] The period of the measurement window for receiving synchronization signals (SS) and / or PBCH blocks, the offset of the measurement window for receiving SS and / or PBCH blocks, and the duration of the measurement window for receiving SS and / or PBCH blocks.

[0181] Each cell can be configured with a set of on-demand SSB configuration information and / or on-demand SSB SMTC configuration information; or all cells can be configured with a set of on-demand SSB configuration information and / or on-demand SSB SMTC configuration information.

[0182] In one implementation, the indication information of the on-demand SSB configuration information is used to indicate whether at least one piece of the on-demand SSB configuration information exists or is retained. For example, the first signaling includes the on-demand SSB period and activation duration, the SMTC measurement window period, and the SMCT measurement window duration. The indication information indicates that the on-demand SSB configuration information exists, that is, the on-demand SSB period and activation duration, the SMTC measurement window period, and the SMCT measurement window duration exist. For example, the first signaling includes the on-demand SSB period and activation duration, the SMTC measurement window period, and the SMCT measurement window duration. The indication information includes indication 1 / 2 / 3 / 4, where indication 1 indicates whether the on-demand SSB period exists or is retained, indication 2 indicates whether the on-demand SSB activation duration exists or is retained, indication 3 indicates whether the SMTC measurement window period exists or is retained, and indication 4 indicates whether the SMCT measurement window duration exists or is retained.

[0183] In one implementation, the indication information is used to indicate whether at least one configuration information in the on-demand SSB configuration information exists or is retained; the indication information indicates that the on-demand SSB configuration information exists, that is, all related SSB configuration information exists. For example, the on-demand SSB configuration information includes the on-demand SSB period and activation duration, and the indication information indicates that the on-demand SSB configuration information exists, that is, both the on-demand SSB period and activation duration exist; the indication information indicates that the on-demand SSB configuration information does not exist, that is, all related configurations do not exist. For example, the on-demand SSB configuration information includes the on-demand SSB period, activation duration, and SSB burst location indication information, and the indication information indicates that the on-demand SSB configuration information does not exist, that is, neither the on-demand SSB period, activation duration, nor the SSB burst location indication information exists in the first signaling; the indication information indicates that the on-demand SSB configuration information is a retained value, that is, all related configurations are retained values ​​in the first signaling.

[0184] For example, the on-demand SSB configuration information includes the on-demand SSB period and activation duration, and the indication information includes indication 1 / 2. Indication 1 indicates whether the on-demand SSB period exists or is retained, and indication 2 indicates whether the on-demand SSB activation duration exists or is retained.

[0185] In one implementation, the indication information is used to indicate whether at least one configuration piece of information in the on-demand SSB's SMTC configuration information exists or is retained. The indication information indicates that the on-demand SSB's SMTC configuration information exists, meaning that all relevant on-demand SSB SMTC configuration information exists. For example, if the on-demand SSB's SMTC configuration information includes the SMTC measurement window period and the SMCT measurement window duration, the indication information indicates that both the SMTC measurement window period and the SMCT measurement window duration exist. Alternatively, the indication information indicates that the n-demand SSB's SMTC configuration information does not exist, meaning that none of the relevant configurations exist. For example, if the on-demand SSB's SMTC configuration information includes the SMTC measurement window period and the SMCT measurement window duration, the indication information indicates that neither the SMTC measurement window period nor the SMCT measurement window duration exists. Finally, the indication information indicates that the on-demand SSB's SMTC configuration information is a retained value.

[0186] For example, the SMTC configuration information of the on-demand SSB includes the SMTC measurement window period and the SMTC measurement window duration. The indication information includes indication 1 / 2. Indication 1 indicates whether the SMTC measurement window period exists or is retained, and indication 2 indicates whether the SMTC measurement window duration exists or is retained.

[0187] The indication information can be used to indicate whether at least one piece of the on-demand SSB configuration information for each cell exists or is retained, or the indication information can be used to indicate whether at least one piece of the on-demand SSB configuration information for all cells exists or is retained. The cell can be the cell that activated on-demand SSB in the first signaling.

[0188] The above indication information can be a special value of at least one of the relevant configuration information of the on-demand SSB.

[0189] The indication information can be either the on-demand SSB period or the SMTC measurement period. When the period is a first value, at least one piece of information indicating the on-demand SSB configuration information exists. For example, the first signaling includes the on-demand SSB period and activation duration, the SMTC measurement window period, and the SMCT measurement window duration. When the on-demand SSB period is a first value, that is, the on-demand SSB period and activation duration, the SMTC measurement window period, and the SMCT measurement window duration exist. When the period is a second value, at least one piece of information indicating the on-demand SSB configuration information does not exist. For example, the first signaling includes the on-demand SSB period and activation duration, the SMTC measurement window period, and the SMCT measurement window duration. When the on-demand SSB period is a second value, that is, the on-demand SSB period and activation duration, the SMTC measurement window period, and the SMCT measurement window duration do not exist.

[0190] The indication information can be the on-demand SSB period. If the period is a first value, it indicates that at least one configuration information in the on-demand SSB configuration information exists. For example, the on-demand SSB configuration information includes the on-demand SSB period and the activation duration. If the on-demand SSB period is a first value, it means that the on-demand SSB period and the activation duration exist. If the period is a second value, it indicates that at least one configuration information in the on-demand SSB configuration information does not exist. For example, if the on-demand SSB configuration information includes the on-demand SSB period and the activation duration, if the on-demand SSB period is a second value, it means that the on-demand SSB period and the activation duration do not exist.

[0191] The indication information can be the SMTC cycle of the on-demand SSB. When the cycle is a first value, it indicates that at least one configuration information in the SMTC configuration information of the on-demand SSB exists. For example, the SMTC configuration information includes the SMTC measurement window cycle and the SMCT measurement window duration. When the SMTC measurement window cycle of the on-demand SSB is a first value, it means that the SMTC measurement window cycle and the SMCT measurement window duration exist. When the cycle is a second value, it indicates that at least one configuration information in the on-demand SSB configuration information does not exist. For example, the on-demand SSB configuration information includes the on-demand SSB cycle and the activation duration. When the on-demand SSB cycle is a second value, it means that the on-demand SSB cycle and the activation duration do not exist.

[0192] In some implementations, the above indication information may also include at least one of the following special values: SSB configuration identifier, on-demand SSB activation time, on-demand SSB burst number, SSB frequency point, SSB subcarrier spacing, SSB related power information, SSB burst position indication information, offset of the measurement window for receiving SS and / or PBCH blocks, and duration of the measurement window for receiving SS and / or PBCH blocks. See above for specific implementation details.

[0193] For ease of explanation, the following embodiments only illustrate the signaling format when configuring the on-demand SSB period and on-demand SSB activation time in the on-demand SSB configuration information.

[0194] Referring to Figure 5, this figure is a schematic diagram of the signaling format provided in the embodiments of this application.

[0195] The first signaling shown in the figure can be the signaling of the Media Access Control Element (MAC CE). Taking the signaling shown in Figure 5 as the first signaling, this first signaling includes the second information.

[0196] Figure 5 illustrates this using an example where each line of the first signaling consists of 8 bits.

[0197] The second information corresponds to one or more secondary cell SCells. As shown in Figure 5, the first signaling can be used to indicate the activation of on-demand SSBs for up to seven cells. That is, each bit in C1 to C7 in Figure 5 corresponds to one SCell. When Ci is the first content, it indicates activation of the on-demand SSB corresponding to that SCell; when Ci is the second content, it indicates deactivation of the on-demand SSB corresponding to that SCell. The first content can be 1, and the second content can be 0; or, the first content can be 0, and the second content can be 1. Field R is a reserved field, used for format alignment.

[0198] It is understandable that one or more of the C1-C7 fields in Figure 5 can be replaced with the R field to reduce the number of secondary cells corresponding to the second information. For example, C2-C7 can all be replaced with the R field, in which case the second information corresponds to one SCell.

[0199] The Scell ​​can have a maximum of 31 cells, meaning it can include a first signaling signal indicating a maximum of 7 cells and a second signaling signal indicating a maximum of 31 cells. When the number of configured secondary cells is less than 8 (less than or equal to 7), the first signaling signaling is used; when the number of configured secondary cells is greater than or equal to 8 (greater than 7), the second signaling signaling is used. The first and second signaling signals are identified using different Logical Channel Identifiers (LCIDs) or Extended Logical Channel Identifiers (eLCIDs).

[0200] When the on-demand SSB of an SCell is activated, the on-demand SSB configuration and / or the SMTC configuration of the on-demand SSB must both exist. For example, when Ci is the first content, it indicates that the on-demand SSB of the SCell corresponding to Ci is activated, and at the same time indicates that the on-demand SSB configuration and / or the SMTC configuration of the on-demand SSB corresponding to that SCell must both exist.

[0201] The period of the SSB (represented by periodicity in Figure 5) can be: 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, spare2, spare1.

[0202] The activation time of the SSB (represented by duration in Figure 5) can be: 5sf, 10sf, 20sf, 40sf, 80sf, 160sf, 320sf, or 640sf. Here, sf represents a subframe.

[0203] The SMTC configuration period can be: 5ms, 10ms, 20ms, 40ms, 80ms, 160ms. Or 5sf, 10sf, 20sf, 40sf, 80sf, 160sf.

[0204] The offset values ​​for SMTC are as follows: when the period is 5sf, the offset value is 0sf-4sf; when the period is 10sf, the offset value is 0sf-9sf; when the period is 20sf, the offset value is 0sf-19sf; when the period is 40sf, the offset value is 0sf-39sf; when the period is 80sf, the offset value is 0sf-79sf; and when the period is 160sf, the offset value is 0sf-159sf.

[0205] The duration of the measurement window for SMTC (represented by duration in Figure 5) can be: 1sf, 2sf, 3sf, 4sf, 5sf.

[0206] The SSB configuration cycle value requires 3 bits, and the SMTC configuration cycle value requires 3 bits. Similarly, the SSB activation time configuration requires 3 bits, and the SMTC measurement window duration configuration requires 3 bits. Therefore, the first two rows of Ci in Figure 5 contain reserved bits. According to the example in Figure 5, the first group of SSB configuration information appearing is for C1, which is only one example. When the first group of SSB-related configuration information is for C2, then the cell corresponding to the first group of SSB-related configuration information is C2. C1-C7 correspond to SCellIndex in sequence, with C1 corresponding to SCellIndex1, C2 to SCellIndex2, and so on. If Ci has no corresponding SCellIndex, then Ci is ignored. For example, if SCellIndex includes SCellIndex1 and SCellIndex2, then C3-C7 have no corresponding cells.

[0207] The following explains the meaning of the SSB activation time field.

[0208] Table 1: Relationship between the corresponding meanings of SSB activation time duration

[0209] The following explains the meaning of the SSB periodic field.

[0210] Table 2: Relationship Table of Corresponding Meanings of the SSB Periodicity Field

[0211] The following explains the meaning of the SMTC period field.

[0212] Table 3: Relationship Table of Corresponding Meanings of the SMTC Periodicity Field

[0213] The following explains the meaning of the duration field in the SMTC measurement window.

[0214] Table 4: Relationship between the meanings of the duration field in the SMTC measurement window

[0215] In one possible implementation, the network device does not configure the SSB and SMTC in the first signaling. For example, it can use the content pre-configured by Radio Resource Control (RRC). In this case, the SSB periodicity field can be used as the first indication information for the relevant configuration information of the on-demand SSB, and / or the SMTC periodicity field can be used as the second indication information for the relevant configuration information of the on-demand SSB.

[0216] When the first indication information is the SSB periodicity field, a special value indicates that there is no relevant configuration. For example, in Table 2, when the SSB periodicity field is set to the first value (000 in Table 2), it is reserved, indicating no special meaning and indicating that at least one item of the on-demand SSB configuration information is missing. For example, it may only indicate that the SSB period is missing, or it may indicate that one or more of the following SSB configurations are missing: SSB configuration identifier, on-demand SSB period, on-demand SSB activation time, on-demand SSB burst count, SSB frequency point, SSB subcarrier spacing, related SSB power information, SSB burst location indication information, etc.

[0217] When the second indication information is the SMTC periodicity field, a special value indicates that there is no relevant configuration. For example, in Table 3, when the SMTC periodicity field is set to the first value (000 in Table 3), it is reserved, indicating no special meaning and that at least one item of the SMTC configuration information is missing. For example, it may only indicate that the SMTC periodic configuration is missing, or it may indicate that one or more of other SMTC configurations, such as the offset of the measurement window for receiving SS and / or PBCH blocks, or the duration of the measurement window for receiving SS and / or PBCH blocks, are missing.

[0218] In this mode, for a SCell with an activated on-demand SSB, the first indication information can be used to indicate whether the SSB configuration of all or part of the SCell in the first signaling is retained or does not exist, and / or the second indication information can be used to indicate whether the SMTC configuration information of the SSB of all or part of the SCell in the first signaling is retained or does not exist.

[0219] For example, if both C1 and C2 are 1, it means that the on-demand SSB of the SCells corresponding to C1 and C2 are both activated. At this time, the SSB configuration and SMTC configuration of the SCell corresponding to C1 can be configured by the first signaling. The periodicity field of the SSB configuration and the periodicity field of the SMTC configuration of C2 are both 000, indicating that the first signaling has not configured the SSB configuration and SMTC configuration of the SCell corresponding to C2. The SSB configuration and SMTC configuration of the SCell corresponding to C2 can be the content pre-configured by RRC.

[0220] When the first indication information is the SSB periodicity field, if the SSB period is the first value, it indicates that at least one item of the on-demand SSB configuration information is reserved or does not exist. For example, it indicates that the on-demand SSB period and / or activation time does not exist. For example, as shown in Figure 5, when the SSB period is the first value, the activation time configured by the SSB is reserved and set to 0. According to the figure above, the activation time of the SSB should be 5ms (1ms for one subframe). However, since the SSB period is the first value, the activation time of the SSB being 0 does not have the meaning of 5ms, but rather means that it is not configured.

[0221] In another possible implementation, see Figure 6, which is a schematic diagram of the signaling format provided in the embodiments of this application.

[0222] The difference between the implementation shown in Figure 6 and Figure 5 is that the SSB periodicity1 field and the SMTC periodicity2 field are on the same line (same byte); the SSB activation time field duration1 field and the SMTC periodic measurement window duration field duration2 field are on the same line (same byte). In this implementation, the first indication information may include the SSB periodicity field periodicity1. When periodicity1 takes the first value, it indicates that at least one item of the on-demand SSB configuration information is reserved or does not exist. For example, when the periodicity1 field takes a special value, such as 000, it can indicate that the SSB periodic configuration does not exist; or that the SSB periodic configuration and activation time do not exist; or that the SSB periodic configuration and activation time do not exist, and the measurement window duration, measurement window period, offset, etc. in the on-demand SSB SMTC configuration do not exist. In this case, the UE does not need to read and continue reading subsequent information, which can save signaling. In this case, configuration information 1, which takes a special value to indicate whether configuration information 2 exists, can be placed before other configuration information 2, so that some configuration information fields do not need to be carried in the MAC CE. When configuration information 1, which takes a special value to indicate whether configuration information 2 exists, is in the same byte as other configuration information 2, then configuration information 2 is reserved and / or set to 0.

[0223] Similarly, the SMTC periodicity2 field can also serve as an indication. The value of periodicity2 indicates whether at least one item of the on-demand SSB's SMTC configuration information is retained or not present, which will not be elaborated further here.

[0224] Furthermore, in some embodiments, the SSB activation time field duration1 and / or the SMTC measurement window duration field duration2 can also serve as indication information to indicate whether at least one item of the corresponding configuration information is retained or does not exist. However, it should be noted that, referring to Table 1, since each value of the SSB activation time field has a corresponding specific duration meaning, if the first indication information includes duration1, the meaning of one of the SSB activation time field values ​​in Table 2 needs to be adjusted to indicate whether at least one item of the on-demand SSB configuration information is retained or does not exist. For example, when the SSB activation time field value is 000, its corresponding meaning is no longer an activation time of 5 seconds, but rather an indication that at least one item of the on-demand SSB configuration information is retained or does not exist.

[0225] In the above implementation, when Ci in the first row of Figures 5 and 6 is the first content, it indicates that the on-demand SSB corresponding to the SCell is activated; when Ci is the second content, it indicates that the on-demand SSB corresponding to the SCell is deactivated.

[0226] In another possible implementation, when Ci in the first row of Figure 5 is the first content, it instructs the activation of the SCell corresponding to Ci and the activation of the on-demand SSB corresponding to the SCell; when Ci is the second content, it instructs the deactivation of the SCell corresponding to Ci and the deactivation of the on-demand SSB corresponding to the SCell. For example, the first content can be 1 and the second content can be 0; or, the first content can be 0 and the second content can be 1. Field R is a reserved field, used to implement format alignment.

[0227] At this time, the activation indication information of the on-demand SSB is also used to activate or deactivate the corresponding secondary cell. That is, the activation of the secondary cell and the on-demand SSB is completed by a single MAC CE signaling, reducing the number of interactions between the network device and the UE. The third indication information uses fields S1-S7 to independently indicate whether the SCell corresponding to C1-C7 is activated. Simultaneously, fields C1-C7 can indicate whether the corresponding on-demand SSB is activated or deactivated.

[0228] In addition, the first signaling can also independently indicate the activated on-demand SSB, which will be explained in detail below with reference to the attached diagram.

[0229] See Figure 7, which is a schematic diagram of the signaling format provided in the embodiments of this application.

[0230] In this implementation, the activation indication information of the on-demand SSB includes a third indication information, meaning the second information includes the third indication information. The third indication information is used to individually indicate whether the relevant configuration information of the on-demand SSB of each secondary cell is activated.

[0231] Specifically, the third indication information uses fields S1-S7 to independently indicate whether the on-demand SSB corresponding to C1-C7 is activated or deactivated. Simultaneously, fields C1-C7 can indicate whether the corresponding SCell is activated.

[0232] Understandably, one or more of the C1-C7 fields in Figure 7 can be replaced with the R field to reduce the number of secondary cells corresponding to the second information. In this case, the corresponding fields in the S1-S7 fields are also replaced with the R field. For example, if C2-C7 are all replaced with the R field, and the second information corresponds to one SCell, then the S2-S7 fields are also replaced with the R field.

[0233] When Ci is the first content, it indicates that the SCell is active; when Ci is the second content, it indicates that the SCell is deactivated. The first content can be 1, and the second content can be 0; or, the first content can be 0, and the second content can be 1. i is an integer ranging from 1 to 7.

[0234] When Si is the first content, it indicates that the on-demand SSB corresponding to Ci is activated; when Si is the second content, it indicates that the on-demand SSB corresponding to Ci is deactivated. The first content can be 1 and the second content can be 0; or, the first content can be 0 and the second content can be 1.

[0235] This implementation separates the indication of the related configurations for SCell and on-demand SSB, offering high flexibility. For example, when C1 is 1 and S1 is 0, it indicates that the SCell corresponding to C1 is active, and that the on-demand SSB of the SCell corresponding to C1 is not active.

[0236] When the on-demand SSB is activated, the on-demand SSB configuration and the SMTC configuration of the on-demand SSB corresponding to the SCell exist simultaneously.

[0237] In another possible implementation, the second information may include an on-demand indication, which indicates whether the on-demand SSB of the "activated SCell" is activated simultaneously, as described in detail below with reference to the accompanying drawings.

[0238] See Figure 8, which is a schematic diagram of the signaling format provided in the embodiments of this application.

[0239] In this implementation, the second information may include on-demand instructions, for example, on-demand instructions may be specifically included in the activation instruction information of the on-demand SSB.

[0240] In one possible implementation, the on-demand indication may include an on-demand indication field, such as the OD field in Figure 8. When the OD field is the first content, it indicates that the on-demand SSB of the "activated SCell" is activated simultaneously. When the OD field is the second content, it indicates that the on-demand SSB of the "activated SCell" is deactivated simultaneously. The first content can be 1, and the second content can be 0; or, the first content can be 0, and the second content can be 1. Meanwhile, the C1-C7 fields can indicate whether the corresponding SCell is activated. For example, if C1 is 1, it indicates that the SCell corresponding to C1 is activated. At this time, if OD is 1, it indicates that the on-demand SSB of the SCell corresponding to C1 is activated. When the on-demand SSB is activated, the on-demand SSB configuration and / or the SMTC configuration of the on-demand SSB corresponding to that SCell exist simultaneously. Another example is that if C1 is 1 and OD is 0, it indicates that the on-demand SSB of the SCell corresponding to C1 is deactivated when the SCell corresponding to C1 is activated.

[0241] Referring again to Figure 8, in another possible implementation, the second information may include an on-demand indication, which indicates whether the activation indication information of the on-demand SSB is also used to activate the SCell.

[0242] In this implementation, the second information may include on-demand instructions, for example, on-demand instructions may be specifically included in the activation instruction information of the on-demand SSB.

[0243] In one possible implementation, the on-demand indication may include an on-demand indication field, such as the OD field in Figure 8. When the OD field is the first content, it indicates that the SCell and its on-demand SSB are activated simultaneously. When the OD field is the second content, it indicates that the SCell and its on-demand SSB are deactivated simultaneously. The first content can be 1, and the second content can be 0; or, the first content can be 0, and the second content can be 1. Meanwhile, the C1-C7 fields can indicate the SCells that need to be activated. For example, if C1 is 1, it indicates that the SCells that need to be activated include the SCell corresponding to C1. In this case, OD is 1, indicating that the SCell corresponding to C1 and its on-demand SSB need to be activated simultaneously.

[0244] Referring again to Figure 8, in another possible implementation, the second information may include an on-demand indication, which is used to indicate whether the corresponding cell should be activated simultaneously.

[0245] In this implementation, the second information may include on-demand instructions, for example, on-demand instructions may be specifically included in the activation instruction information of the on-demand SSB.

[0246] On-demand indications can include on-demand indication fields, such as the OD field in Figure 8. Meanwhile, the C1-C7 fields can indicate whether the on-demand SSB of the corresponding cell is activated. For example, if C1 is 1, it indicates that the on-demand SSB of the SCell corresponding to C1 needs to be activated, and if OD is 1, it indicates that the SCell corresponding to C1 is activated simultaneously.

[0247] In the embodiments corresponding to Figures 5-8 above, the example is taken where the first signaling simultaneously configures both on-demand SSB configuration information and on-demand SSB SMTC configuration information. In another possible implementation, the on-demand SSB related configuration information of the first signaling may only include on-demand SSB configuration information. In this case, the fields corresponding to the SMTC configuration information in Figures 5-8 are either absent or reserved. For the unconfigured information, it can be sent by another signaling, for example, by another MAC CE carrying third information. The third information is used to configure the related configuration information of the first SSB, which includes the configuration information of the first SSB and / or the SMTC configuration information of the first SSB. In this case, the third information can specifically carry the on-demand SSB SMTC configuration information, for example, through other signaling.

[0248] In another possible implementation, the on-demand SSB configuration information of the first signaling may only include the SMTC configuration information of the on-demand SSB. In this case, the fields corresponding to the on-demand SSB configuration information in Figures 5-8 are either absent or reserved. It is understandable that unconfigured information can be sent by another signaling, for example, carried in another MAC CE. This third information can specifically carry the on-demand SSB configuration information, for example, through other signaling.

[0249] The configuration information of the on-demand SSB carried in the third information mentioned above can be the configuration information of the first SSB, which is a periodically sent SSB. In this implementation, the first SSB is an always-on SSB. When configuring the on-demand SSB in the first signaling, the always-on SSB is not completely updated, but only a part of its configuration information is updated, while the remaining configuration information uses the configuration information of the first SSB.

[0250] Furthermore, in another possible implementation, when the first signaling configures only one of the on-demand SSB configuration information or the on-demand SSB SMTC configuration information, the other configuration information can also be carried using pre-configured content via RRC or other signaling. That is, the on-demand SSB configuration information and the on-demand SSB SMTC configuration information are carried using different signaling.

[0251] In the above embodiments, the first signaling indicates the on-demand SSB activation of up to 7 cells through the C1-C7 fields. In another possible implementation, the C1-C7 fields can be used to indicate the on-demand SSB activation of up to 31 cells, in which case the signaling including the second information is the second signaling.

[0252] The first and second signaling signals are identified by different Logical Channel IDs (LCIDs) or Extended Logical Channel IDs (eLCIDs).

[0253] Specifically, the logical channel identifier is 1 byte; the extended logical channel identifier is 1 byte or 2 bytes. When the logical channel identifier is 33, it indicates that the extended logical channel identifier is 2 bytes. When the logical channel identifier is 34, it indicates that the extended logical channel identifier is 1 byte.

[0254] The following explains how to determine whether the specific content in the on-demand SSB configuration information exists or is reserved, based on the first signaling indication.

[0255] See also Figures 9A and 9B. Figure 9A is a schematic diagram of the signaling format provided in the embodiment of this application (Figure 5); Figure 9B is a schematic diagram of the signaling format provided in the embodiment of this application (Figure 6).

[0256] In this embodiment of the application, the relevant configuration information of the on-demand SSB includes at least the on-demand SSB configuration information, and may also include the SMTC configuration information of the on-demand SSB. The indication information of the relevant configuration information of the on-demand SSB includes third indication information, which may include one or more lines (each line in the figure is one byte), used to indicate whether at least one item in the on-demand SSB configuration information exists or is reserved.

[0257] Figures 9A and 9B illustrate examples where the third instruction information includes a single line. U0 and U1 correspond to the specific content of the on-demand SSB configuration configured by the first signaling for the activated SCell. The first signaling can be MAC CE signaling.

[0258] In this embodiment, U0 corresponds to the period of the on-demand SSB, and U1 corresponds to the activation time of the on-demand SSB, as an example. When the on-demand SSB configuration includes more items, the R field in the second row can be replaced with the corresponding indicator field, such as U3 corresponding to the number of bursts of the on-demand SSB, U4 corresponding to the SSB frequency point, U5 corresponding to the subcarrier spacing of the SSB, etc., which will not be elaborated here.

[0259] In one possible implementation, as shown in Figure 9A, the third indication information simultaneously indicates the on-demand SSB configuration information of all SCells that have activated on-demand SSB in the first signaling. In this case, all activated SCells share a set of indications.

[0260] For example, in Figure 9A, if C1-C3 are 1 and C4-C7 are 0, it indicates that the on-demand SSB of the SCells corresponding to C1-C3 is active. At this time, the third indication information also indicates the configuration information of the on-demand SSB for C1-C3. When the U0 and U1 fields are the first content, it indicates that the period and activation time of the on-demand SSB for C1-C3 exist or are configured. When the U0 and U1 fields are the second content, it indicates that the period and activation time of the on-demand SSB for C1-C3 do not exist or are not configured. The first content can be 1 and the second content can be 0; or, the first content can be 0 and the second content can be 1. In this case, the last three rows of bits in the third indication information in Figure 9A correspond to the relevant configuration information for C1, the three rows of bits after the relevant configuration information for C1 correspond to the relevant configuration information for C2, and the three rows of bits after the relevant configuration information for C2 correspond to the relevant configuration information for C3. When Ci is 1 in the first signaling, but there is no relevant configuration information for Ci in the first signaling, it can be assumed that the network device has not updated the relevant configuration information for Ci in the first signaling. The relevant configuration information for Ci can use the latest saved configuration information. This configuration information can be configured by MAC CE or by RRC. This application embodiment does not make specific limitations, or the relevant configuration information configured by RRC can be used by default.

[0261] In another possible implementation, as shown in Figure 9B, the third indication information can indicate whether at least one item in the on-demand SSB configuration information of each SCell activating the on-demand SSB in the first signaling exists or is reserved, thus achieving more flexible content indication. In this case, the third indication information can include multiple sets of indications (each set of indications in Figure 9B includes one line of bits, therefore the third indication information can include a maximum of 7 lines). Specifically, the third indication information can include N sets of indications, where N is the number of SCells activating the on-demand SSB.

[0262] For example, in Figure 9B, C1-C2 and C4 are 1, and C3 and C5-C7 are 0, indicating that the on-demand SSB of the SCells corresponding to C1, C2, and C4 is active at this time. It is understandable that in one possible implementation, the activation of the SCells corresponding to C1, C2, and C4 can also be indicated simultaneously. When the on-demand SSB of the SCells corresponding to C1, C2, and C4 is active, the third indication information simultaneously indicates the configuration information of the on-demand SSB of the SCells corresponding to C1, C2, and C4. For example, when the U0 and U1 fields in each byte are the first content, it indicates that the period and activation time of the on-demand SSB of the SCells corresponding to C1, C2, and C4 exist or are configured; when the U0 and U1 fields in each byte are the second content, it indicates that the period and activation time of the on-demand SSB of the SCells corresponding to C1, C2, and C4 do not exist or are not configured. The first content can be 1, and the second content can be 0; or, the first content can be 0, and the second content can be 1. In this case, the last three rows of bits in the third indication information in Figure 9B correspond to the relevant configuration information of C1, the last three rows of bits after the relevant configuration information of C1 correspond to the relevant configuration information of C2, and the last three rows of bits after the relevant configuration information of C2 correspond to the relevant configuration information of C4. When Ci in the first signaling is 1, but there is no relevant configuration information for Ci in the first signaling, it can be assumed that the network device has not updated the relevant configuration information for Ci in the first signaling. The relevant configuration information for Ci can use the latest saved configuration information, which can be configured by MAC CE or by RRC. This application embodiment does not specifically limit this, or the relevant configuration information configured by RRC can be used by default.

[0263] See also Figures 9C and 9D. Figure 9C is a schematic diagram (7) of the signaling format provided in the embodiments of this application; Figure 9D is a schematic diagram (8) of the signaling format provided in the embodiments of this application.

[0264] In this embodiment of the application, the relevant configuration information of the on-demand SSB includes at least the SMTC configuration information of the on-demand SSB, and may also include the on-demand SSB configuration information. The indication information of the relevant configuration information of the on-demand SSB includes fourth indication information, which may include one or more lines (each line in the figure is one byte), used to indicate whether at least one item in the SMTC configuration information of the on-demand SSB exists or is reserved.

[0265] In Figures 9C and 9D, taking the fourth indication information as an example, U2, U3, and U4 correspond to the specific content of the SMTC configuration information of the on-demand SSB configured by the activated SCell through the first signaling. The first signaling can be MAC CE signaling.

[0266] In this embodiment, U2 corresponds to the period of the measurement window for receiving SS and / or PBCH blocks, U3 corresponds to the offset of the measurement window for receiving SS and / or PBCH blocks, and U4 corresponds to the duration of the measurement window for receiving SS and / or PBCH blocks.

[0267] In one possible implementation, as shown in Figure 9C, the fourth indication information simultaneously indicates the on-demand SSB configuration information of all SCells with activated on-demand SSBs in the first signaling. In this case, all activated SCells share a single set of indications. For example, if C1-C3 is 1 and C4-C7 is 0 in Figure 9C, it indicates that the on-demand SSB of the SCells corresponding to C1-C3 is activated. At this time, the fourth indication information simultaneously indicates the SMTC configuration information of the on-demand SSBs of C1-C3. For instance, when the U2 field is the first content, it indicates that the period of the SMTC configuration information of the on-demand SSBs of C1-C3 exists or is configured; when the U2 field is the second content, it indicates that the period of the SMTC configuration information of the on-demand SSBs of C1-C3 does not exist or is not configured. The first content can be 1 and the second content can be 0; or, the first content can be 0 and the second content can be 1. At this time, the last three rows of bits (last three bytes) of the fourth indication information in Figure 9C correspond to the relevant configuration information of C1, the last three rows of bits after the relevant configuration information of C1 correspond to the relevant configuration information of C2, and the last three rows of bits after the relevant configuration information of C2 correspond to the relevant configuration information of C3. When Ci in the first signaling is 1, but there is no relevant configuration information for Ci in the first signaling, it can be assumed that the network device has not updated the relevant configuration information for Ci in the first signaling. The relevant configuration information for Ci can use the latest saved configuration information, which can be configured by MAC CE or by RRC. This application embodiment does not make specific limitations, or the relevant configuration information configured by RRC can be used by default.

[0268] In another possible implementation, as shown in Figure 9D, the fourth indication information can indicate whether at least one item in the on-demand SSB configuration information of each SCell activating the on-demand SSB in the first signaling exists or is reserved, thus achieving more flexible content indication. In this case, the fourth indication information can include multiple sets of indications (each set of indications in Figure 9D includes one row of bits, therefore the third indication information can include a maximum of 7 rows, and a maximum of 7 bytes). Specifically, the fourth indication information can include N sets of indications, where N is the number of SCells activating the on-demand SSB.

[0269] For example, in Figure 9D, C1-C2 and C4 are 1, and C3 and C5-C7 are 0, indicating that the on-demand SSB of the SCells corresponding to C1, C2, and C4 is active at this time. It is understandable that in one possible implementation, the activation of the SCells corresponding to C1, C2, and C4 can also be indicated simultaneously. When the on-demand SSB of the SCells corresponding to C1, C2, and C4 is active, the fourth indication information simultaneously indicates the SMTC configuration information of the on-demand SSB of the SCells corresponding to C1, C2, and C4. For example, when the U2 field in each byte is the first content, it indicates that the period of the SMTC configuration information of the on-demand SSB of C1, C2, and C4 exists or is configured; when the U2 field in each byte is the second content, it indicates that the period of the SMTC configuration information of the on-demand SSB of C1, C2, and C4 does not exist or is not configured. At this time, the last three rows of bits (last three bytes) of the fourth indication information in Figure 9D correspond to the relevant configuration information of C1, the last three rows of bits after the relevant configuration information of C1 correspond to the relevant configuration information of C2, and the last three rows of bits after the relevant configuration information of C2 correspond to the relevant configuration information of C4. When Ci in the first signaling is 1, but there is no relevant configuration information for Ci in the first signaling, it can be assumed that the network device has not updated the relevant configuration information for Ci in the first signaling. The relevant configuration information for Ci can use the latest saved configuration information, which can be configured by MAC CE or by RRC. This application embodiment does not make specific limitations, or the relevant configuration information configured by RRC can be used by default.

[0270] Furthermore, please refer to Figures 10A and 10B together. Figure 10A is a schematic diagram nine of the signaling format provided in the embodiment of this application; Figure 10B is a schematic diagram ten of the signaling format provided in the embodiment of this application.

[0271] In this embodiment, the configuration information related to the on-demand SSB includes both the SMTC configuration information and the on-demand SSB configuration information. The indication information of the on-demand SSB configuration information may include both third and fourth indication information. In this case, the third and fourth indication information can be located on the same line (the same byte). For the specific implementation of the third and fourth indication information, please refer to the above description, which will not be repeated here.

[0272] In one possible implementation, the network device can activate the secondary cell via a MAC CE and activate the on-demand SSB of that secondary cell, as described in detail below with reference to the accompanying drawings.

[0273] Referring to Figure 11, this figure is a schematic diagram of the signaling format provided in the embodiments of this application.

[0274] In this implementation, the first information includes activation indication information for the on-demand SSB, which is used to indicate the on-demand SSB of the target cell. The second information may include relevant configuration information of the on-demand SSB of the target cell and indication information of the relevant configuration information of the on-demand SSB.

[0275] In Figure 11, the signaling including the first information and the second information is the first signaling, which can be a MAC CE. The first signaling includes a field indicating the target cell and a Cell ID field, used to indicate the corresponding SCell. The on-demand SSB of the SCell corresponding to the Cell ID is configured through the first signaling. The first signaling may not include the first information, and may only configure the on-demand SSB of the SCell corresponding to the Cell ID.

[0276] The relevant configuration information for on-demand SSB includes the N1 and N2 fields.

[0277] The N1 field is used to indicate whether an on-demand SSB configuration exists. When the N1 field is the first value, it indicates the presence of an on-demand SSB configuration; when the N1 field is the second value, it indicates the absence of an on-demand SSB configuration. The first value can be 1, and the second value can be 0; alternatively, the first value can be 0, and the second value can be 1.

[0278] Understandably, the N1 field above can also be replaced with the U0 and U1 fields in the corresponding descriptions in Figure 9A or Figure 9B. In this case, it occupies more bit positions, but it can indicate whether at least one specific item in the on-demand SSB of the SCell corresponding to the Cell ID exists or is reserved, so as to achieve a more granular indication. For example, U0 corresponds to the period of the on-demand SSB, and U1 corresponds to the activation time of the on-demand SSB, which will not be elaborated here.

[0279] The N2 field is used to indicate whether an on-demand SSB SMTC configuration exists. When the N2 field is the first value, it indicates the existence of an on-demand SSB SMTC configuration; when the N2 field is the second value, it indicates the absence of an on-demand SSB SMTC configuration. The first value can be 1, and the second value can be 0; alternatively, the first value can be 0, and the second value can be 1.

[0280] Understandably, the N2 field above can also be replaced with the U2, U3, and U4 fields in the corresponding descriptions of Figure 9C or Figure 9D. In this case, it occupies more bit positions, but it can indicate whether at least one specific item in the SMTC configuration information of the on-demand SSB of the SCell corresponding to the Cell ID exists or is reserved, so as to achieve a more granular indication. For example, U2 corresponds to the period of the measurement window for receiving SS and / or PBCH blocks, U3 corresponds to the offset of the measurement window for receiving SS and / or PBCH blocks, and U4 corresponds to the duration of the measurement window for receiving SS and / or PBCH blocks, which will not be elaborated here.

[0281] In one possible implementation, the Cell ID in the first signaling message can also be used to indicate the order in which the SCells currently activating the on-demand SSB are. When the UE receives multiple first signaling messages, it activates the on-demand SSB of the SCell corresponding to the Cell ID in each signaling message in the order in which the signaling messages are received. For example, if cell1, cell2, and cell5 are activated, and cell ID is sequence number 3, then the configuration information of the OD-SSB of cell5 is configured.

[0282] In one possible implementation, refer to Figure 12, which is a schematic diagram of the signaling format provided in the embodiments of this application. The difference between Figure 12 and Figure 11 is that the first signaling in Figure 11 is split into two signaling signals, both of which can be MAC CE. One signaling signal is used to indicate whether an on-demand SSB configuration exists, as shown in 12-(A) of Figure 12; the other signaling signal is used to indicate whether an on-demand SSB SMTC configuration exists, as shown in 12-(B) of Figure 12.

[0283] In one possible implementation, the signaling shown in Figures 11 and 12 can be used to indicate the activation of the on-demand SSB for the SCell corresponding to the Cell ID. When the on-demand SSB is activated, the on-demand SSB configuration and the SMTC configuration of the on-demand SSB corresponding to that SCell exist simultaneously.

[0284] In another possible implementation, the signaling shown in Figures 11 and 12 is not used to instruct the activation of the on-demand SSB of the SCell corresponding to the Cell ID, but only to carry the relevant configuration information of the on-demand SSB and the instruction information related to the on-demand SSB. In this case, additional signaling is required to activate the on-demand SSB of the SCell corresponding to the Cell ID.

[0285] Furthermore, for the two possible implementation methods mentioned above, the signaling shown in Figures 11 and 12 does not indicate which SCell is activated or whether each SCell is activated. Therefore, the network device still needs to send a message to the UE to activate the SCell, which will be explained in detail below.

[0286] Referring to Figure 13, this figure is a schematic diagram of the signaling format provided in the embodiments of this application.

[0287] At this time, the network device sends a fourth message to the UE. This fourth message is used to activate the SCell and / or activate the cell's OD-SSB. After receiving the fourth message from the network device, the UE will activate the corresponding SCell and / or send the cell's on-demand SSB according to the configuration in Figure 11 or 12 above.

[0288] Signalling that includes the fourth information can be called second signaling, and second signaling is different from signaling that includes the second information. That is, second signaling and signaling that includes the second information are different MAC CE signaling, and can be identified by different Logical Channel IDs (LCIDs) or Extended Logical Channel IDs (eLCIDs). LCIDs and eLCIDs can be located in the header information (control information) of MAC CE signaling.

[0289] In one possible implementation, as shown in 13-(A) of Figure 13, each bit in C1 to C7 of the second signaling corresponds to a SCell. When Ci is the first content, it indicates activation of the on-demand SSB corresponding to the SCell; when Ci is the second content, it indicates deactivation of the on-demand SSB corresponding to the SCell. The first content can be 1, and the second content can be 0; or, the first content can be 0, and the second content can be 1.

[0290] In this implementation, the signaling shown in Figures 11 and 12 may not have the ability to activate the on-demand SSB of the SCell corresponding to the Cell ID, but is only used to carry the relevant configuration information of the on-demand SSB and the indication information of the relevant configuration information of the on-demand SSB.

[0291] Understandably, one or more of the C1-C7 fields shown in 13-(A) of Figure 13 can be replaced with the R field to reduce the number of secondary cells.

[0292] In another possible implementation, as shown in 13-(B) of Figure 13, each bit in C1 to C7 of the second signaling corresponds to a SCell. Fields S1-S7 independently indicate whether the on-demand SSB corresponding to C1-C7 is activated or deactivated. Simultaneously, the C1-C7 fields can indicate whether the corresponding SCell is activated. When Ci is the first content, it indicates that the SCell is activated; when Ci is the second content, it indicates that the SCell is deactivated. When Si is the first content, it indicates that the on-demand SSB corresponding to Ci is activated; when Si is the second content, it indicates that the on-demand SSB corresponding to Ci is deactivated. The first content can be 1, and the second content can be 0; or, the first content can be 0, and the second content can be 1. This implementation achieves separate indication of the related configurations of SCells and on-demand SSBs, offering high flexibility.

[0293] In one possible implementation, the signaling shown in Figures 11 and 12 can have the capability to activate the on-demand SSB of the SCell corresponding to the Cell ID, as described in detail below. Combining the scheme shown in Figure 11 with the scheme shown in Figure 13, the second information is included in a MAC CE signaling, which can be called the third signaling, specifically as shown in 13-(A) or 13-(B) of Figure 13, that is, the activation indication information of the on-demand SSB is carried through the third signaling. The first information is included in a MAC CE signaling, which can be called the fourth signaling, specifically as shown in Figure 11, and the fourth signaling includes cell identification information, i.e., the Cell ID field. The fourth signaling is used to indicate the activation of the on-demand SSB, specifically, to indicate the activation of the on-demand SSB of the SCell corresponding to the Cell ID. The third and fourth signaling are identified by different LCIDs or eLCIDs. Alternatively, the first information is included in two MAC CE signalings, which can be called the fifth and sixth signalings. The fifth signaling corresponds to Figure 12-(A), and the sixth signaling corresponds to Figure 12-(B). Both the fifth and sixth signaling include cell identification information, i.e., the Cell ID field. The fifth signaling is used to indicate the activation of the on-demand SSB and carries the on-demand SSB configuration information. The sixth signaling is used to indicate the activation of the on-demand SSB and carries the SMTC configuration information of the on-demand SSB. When the UE only receives the fifth signaling, it can use the most recently saved SMTC configuration information of the on-demand SSB for that SCell as the current SMTC configuration information of the on-demand SSB for that SCell. When the UE only receives the sixth signaling, it can use the most recently saved on-demand SSB configuration for that SCell as the current on-demand SSB configuration for that SCell. The UE's most recently saved SMTC configuration information and on-demand SSB configuration can be configured by MAC CE and / or RRC.

[0294] In the above description, the second signaling that activates the on-demand SSB and the signaling that configures the on-demand SSB configuration information are not the same MAC CA. If the UE has stored the on-demand SSB configuration information of the SCell corresponding to the Cell ID locally, when the second signaling shown in Figure 13 deactivates the on-demand SSB, the UE can delete the locally stored on-demand SSB configuration information of the SCell corresponding to the Cell ID.

[0295] The following describes how to obtain the configuration parameters corresponding to the configuration content when one or more of the specific configuration content in the second information indicating on-demand SSB configuration information and / or on-demand SSB SMTC configuration information does not have configuration parameters.

[0296] The following section explains how to obtain on-demand SSB configuration information.

[0297] Referring to Figure 14, this figure is a flowchart of another communication method provided in an embodiment of this application.

[0298] The method includes the following steps:

[0299] S21: The network device sends the fifth information to the UE.

[0300] The fifth piece of information in this application embodiment can be carried in RRC signaling.

[0301] In one possible implementation, the fifth piece of information is used to indicate at least one set of on-demand SSB configuration information. For each set of on-demand SSB configuration information, it may include on-demand SSB configuration information and / or the SMTC configuration information of the on-demand SSB. In this embodiment, the configuration information for each set of on-demand SSB is illustrated by assuming it includes at least on-demand SSB configuration information.

[0302] In RRC signaling, multiple sets of on-demand SSB configuration information are configured for each cell or all cells. The second information indicates which set of on-demand synchronization signal block configuration information in the RRC signaling is used. For example, each set of on-demand SSB configuration information is associated with an index value. The first information is the SSB configuration index value, used to indicate the use of the on-demand SSB configuration information with the index value as the first information. For example, the on-demand SSB configuration information includes SSB configuration information, RRC signaling configures SSB configuration information 1 / 2 / 3. Each set of configuration information includes at least one of the following: SSB configuration identifier, on-demand SSB period, on-demand SSB activation time, on-demand SSB burst number, SSB frequency point, SSB subcarrier spacing, SSB related power information, and SSB burst location indication information. The second information indicates the use of SSB configuration information 1. That is, the terminal equipment uses configuration information 1 to receive on-demand SSB.

[0303] In another possible implementation, the fifth information is used to indicate a list of at least one of the following related configuration information for the on-demand SSB: SSB configuration identifier list, on-demand SSB period list, on-demand SSB activation time list, on-demand SSB burst count list, SSB frequency point list, SSB subcarrier spacing, and SSB subcarrier spacing list.

[0304] In RRC signaling, a list of on-demand SSB configuration information is configured for each cell or all cells. The first piece of information indicates at least one item in the list. For example, each item in the on-demand SSB configuration information list is associated with an index value. The first piece of information is the SSB configuration information index value, used to indicate the use of the on-demand SSB configuration information with the index value as the first item. For example, the on-demand SSB configuration information includes SSB configuration information, and the list information includes an SSB configuration identifier list, an on-demand SSB period list, an on-demand SSB activation time list, an on-demand SSB burst count list, an SSB frequency point list, an SSB subcarrier spacing list, and an SSB subcarrier spacing list. For example, the on-demand SSB period list in RRC signaling is configured as 20ms, 40ms, and 80ms. The second piece of information indicates the use of the first SSB period. That is, the terminal device uses an SSB period of 20ms to receive the on-demand SSB.

[0305] The SSB configuration identifier list is used to identify the configuration information of a set of SSBs.

[0306] The SSB cycle list is used to indicate the transmission cycle of on-demand SSBs.

[0307] The on-demand SSB activation time list is used to indicate the duration of on-demand SSB transmission.

[0308] The burst count list for on-demand SSB is used to indicate the number of bursts sent by on-demand SSB.

[0309] The SSB frequency list is used to indicate the transmission frequency of the SSB reference signal.

[0310] The SSB's SCS list is used to indicate the SSB's subcarrier spacing.

[0311] The SSB burst location indication information list is used to indicate the location information of the transmitted SSB.

[0312] After receiving the fifth message, the UE can save the relevant configuration information of the n-demand SSB carried in the fifth message locally.

[0313] S22: The network device sends the first information and the second information to the UE.

[0314] The second information indication includes activation indication information for the on-demand SSB.

[0315] In one possible implementation, the first information may specifically carry a complete or incomplete set of on-demand SSB configuration information.

[0316] The second and first information can be carried in the same signaling message or in different signaling messages.

[0317] S23: The UE determines to activate the on-demand SSB based on the second information, and determines based on the first information that the configuration information for the on-demand SSB configuration is not configured in the first information.

[0318] In one possible implementation, the first indication information determines the activation of one or more SCells' on-demand SSBs. When the first information is used to carry on-demand SSB configuration information, there may be cases where the on-demand SSB configuration information is incomplete. For example, one or more of the on-demand SSB configuration identifier, period, activation time, number of bursts, frequency point, SSB subcarrier spacing, etc., may not be indicated in the first information. The UE can determine that there is on-demand SSB configuration information that is not configured in the first information and needs to supplement it using locally stored configuration information.

[0319] S24: The UE determines the unconfigured configuration information based on the fifth information.

[0320] For each SCell with activated on-demand SSB, the UE uses the fifth information to match the unconfigured configuration information from the relevant configuration information of on-demand SSB or from the content list of relevant configuration information of on-demand SSB, and then determines a complete set of on-demand SSB configuration for each SCell with activated on-demand SSB.

[0321] In another possible implementation, when the first information indicates the relevant configuration information of the on-demand SSB, it does not carry specific information itself, but instructs the UE to obtain the corresponding information from the fifth information, which will be explained in detail below with reference to the accompanying drawings.

[0322] Referring to Figure 15, this figure is a flowchart of another communication method provided in an embodiment of this application.

[0323] The method includes the following steps:

[0324] S31: The network device sends the fifth message to the UE.

[0325] In one possible implementation, the fifth piece of information is used to indicate at least one set of on-demand SSB configuration information. For each set of on-demand SSB configuration information, it may include on-demand SSB configuration information and / or the SMTC configuration information of the on-demand SSB. In this embodiment, the configuration information for each set of on-demand SSB is illustrated by assuming it includes at least on-demand SSB configuration information.

[0326] In another possible implementation, the fifth information is used to indicate a list of at least one of the following related configuration information for the on-demand SSB: SSB configuration identifier list, on-demand SSB period list, on-demand SSB activation time list, on-demand SSB burst count list, SSB frequency point list, SSB subcarrier spacing, and SSB subcarrier spacing list.

[0327] After receiving the fifth message, the UE can save the relevant configuration information of the n-demand SSB carried in the fifth message locally.

[0328] S32: The network device sends the first information and the second information to the UE.

[0329] In one possible implementation, the first information can be used to indicate at least one set of on-demand SSB configuration information to be used in conjunction with the fifth information. When each set of on-demand SSB configuration information includes at least on-demand SSB configuration information, the first information can indicate at least one specific set of on-demand SSB configuration information to be used.

[0330] The second and first information can be carried in the same signaling message or in different signaling messages.

[0331] S33: The UE determines the SCell to activate the on-demand SSB based on the second information.

[0332] The SCell that activates the on-demand SSB can be one or more, and this application embodiment does not make specific limitations.

[0333] S33: The UE uses at least one set of on-demand SSB configuration information based on the first information, or uses at least one item from the content list of on-demand SSB configuration information.

[0334] For each SCell with activated on-demand SSB, the UE matches the on-demand SSB configuration indicated by the first information from the relevant configuration information of on-demand SSB or from the content list of relevant configuration information of on-demand SSB based on the fifth information, and then determines the on-demand SSB configuration corresponding to each SCell with activated on-demand SSB.

[0335] In some scenarios, the UE may not receive the fifth information before receiving the second and first information, or the on-demand SSB configuration information included in the received fifth information may be incomplete. In this case, the UE can request the network device to configure the relevant information required for the on-demand SSB configuration, which will be explained in detail below.

[0336] Referring to Figure 16, this figure is a flowchart of another communication method provided in an embodiment of this application.

[0337] The method includes the following steps:

[0338] S41: The network device sends the first information and the second information to the UE.

[0339] The second information includes activation instructions for the on-demand SSB. The first information includes relevant configuration information for the on-demand SSB and instructions related to that configuration.

[0340] The second and first information can be carried in the same signaling message or in different signaling messages.

[0341] S42: The UE determines to activate the on-demand SSB based on the second information, and determines based on the first information that the configuration information for the on-demand SSB configuration is not configured in the first information.

[0342] The SCell that activates the on-demand SSB can be one or more, and this application embodiment does not make specific limitations.

[0343] The UE needs to determine whether there is a missing on-demand SSB configuration information for each SCell that has an active on-demand SSB.

[0344] S43: The UE determines that there is no unconfigured configuration information stored locally.

[0345] The UE determines whether the missing configuration information can be obtained based on the latest configuration information stored locally.

[0346] S44: The UE sends the first request to the network device.

[0347] In this embodiment, the UE sends a first request to the network device to request the network device to configure missing information in the on-demand SSB configuration information. This first request may be carried in MAC CE signaling, or in RRC, or in uplink control information (DCI), and this embodiment does not specifically limit the scope.

[0348] The first request may include identifiers of SCells with missing configurations, i.e., Cell IDs. It is understood that these SCells with missing configurations are all SCells with active on-demand SSBs.

[0349] In one possible implementation, the first request may request the network device to send the complete on-demand SSB configuration of the SCell corresponding to the Cell ID, so as to achieve a complete update of the configuration information.

[0350] In another possible implementation, the first request can request the network device to send missing information for the SCell corresponding to the Cell ID. For example, if the on-demand SSB period is missing, then only the on-demand SSB period needs to be resent to reduce the consumption of transmission resources. It is understood that in this implementation, the first request can use a field U to identify the specific missing information, similar to Figures 9A and 9B. For example, U0 corresponds to the specific missing information of the on-demand SSB period, and U1 corresponds to the specific missing information of the on-demand SSB activation time.

[0351] S45: The network device sends the sixth message to the UE.

[0352] After receiving the first request, the network device sends a sixth message to the UE in response to the first request. The sixth message carries missing information for the SCell corresponding to each Cell ID. The sixth message can be MAC CE signaling, RRC, or Downlink Control Information (DCI), and this embodiment does not specify a particular type. After receiving the sixth message, the UE completes the information based on the on-demand SSB configuration information carried in the sixth message, ensuring that the on-demand SSB configuration information of each SCell with activated on-demand SSB is complete.

[0353] The following describes how to obtain the SMTC configuration information for on-demand SSB.

[0354] Referring to Figure 17A, this figure is a flowchart of another communication method provided in an embodiment of this application.

[0355] The method includes the following steps:

[0356] S51: The network device sends the first information and the second information to the UE.

[0357] The second and first information can be carried in the same signaling message or in different signaling messages.

[0358] The second information includes activation instructions for the on-demand SSB. The first information includes relevant configuration information for the on-demand SSB and instructions related to that configuration.

[0359] S52: The UE determines the SCell that activates the on-demand SSB based on the second information, and determines that there is SMTC configuration information for the on-demand SSB that is not configured in the first information.

[0360] The SCell that activates the on-demand SSB can be one or more, and this application embodiment does not make specific limitations.

[0361] The UE needs to determine for each SCell that has an active on-demand SSB whether there is missing SMTC configuration information for the on-demand SSB.

[0362] In this implementation, the second indication information can indicate whether the SMTC configuration information of the on-demand SSB exists or is retained. For example, it can indicate whether one or more of the following exist or are retained: the period of the measurement window for receiving SS and / or PBCH blocks, the offset of the measurement window for receiving SS and / or PBCH blocks, and the duration of the measurement window for receiving SS and / or PBCH blocks. When only one or two of these are indicated to exist, the remaining configuration information is not configured in the first information and the configuration stored locally by the UE needs to be used.

[0363] The configuration stored locally on the UE can be the configuration of the previous MAC CE signaling or RRC.

[0364] S53: The UE determines whether it has received the SMTC configuration information of the on-demand SSB in advance.

[0365] If yes, execute S54; otherwise, execute S59.

[0366] S54: The UE determines whether the missing configuration information can be obtained based on the SMTC configuration information received in advance from the on-demand SSB.

[0367] The UE determines whether the missing configuration information can be obtained based on the latest configuration information stored locally. If yes, it executes S55; otherwise, it executes S56.

[0368] S55: Use the SMTC configuration information of the pre-received on-demand SSB.

[0369] S56: The UE sends the first request to the network device.

[0370] In this embodiment, the UE sends a first request to the network device, requesting the network device to configure the missing content in the SMTC configuration information of the on-demand SSB. This first request can be carried in MAC CE signaling, RRC, or Uplink control information (DCI); this embodiment does not specifically limit this. It is understood that the first request in this step and the first request in S44 of Figure 16 can be the same request or different requests. When they are the same request, the UE sends the first request to the network device to simultaneously remove the missing information in the SMTC configuration information of the on-demand SSB of the SCell corresponding to the Cell ID, as well as the missing information in the on-demand SSB configuration information.

[0371] The first request may include identifiers of SCells with missing configurations, i.e., Cell IDs. It is understood that these SCells with missing configurations are all SCells with active on-demand SSBs.

[0372] In one possible implementation, the first request may request the network device to send the complete on-demand SSB SMTC configuration information for the SCell corresponding to the Cell ID, so as to achieve a complete update of the on-demand SSB SMTC configuration information.

[0373] In another possible implementation, the first request can request the network device to send missing information for the SCell corresponding to the Cell ID. For example, if the measurement window period is missing from the SMTC configuration information of the on-demand SSB, then only the measurement window period needs to be resent to the network device, thus reducing the consumption of transmission resources. In this implementation, the first request can use fields to identify the specific missing information, similar to those in Figures 9C and 9D. For example, U2 corresponds to the period of the SMTC configuration information, U3 corresponds to the duration of the SMTC configuration information, and U4 corresponds to the offset of the SMTC configuration information.

[0374] S57: The UE receives the sixth information sent by the network device.

[0375] After receiving the first request, the network device sends a sixth message to the UE in response to the first request. The sixth message carries missing information for the SCell corresponding to each Cell ID. The sixth message can be MAC CE signaling, RRC, or DCI, and this embodiment does not specifically limit it.

[0376] S58: The UE obtains the SMTC configuration information of the on-demand SSB based on the sixth information sent by the network device.

[0377] After receiving the sixth message, the UE completes the information based on the SMTC configuration information of the on-demand SSB carried in the sixth message, ensuring that the SMTC configuration information of the on-demand SSB of each SCell that activates the on-demand SSB is complete.

[0378] S59: The UE determines whether it has received the SMTC configuration information of always-on SSB in advance.

[0379] If yes, execute S60; otherwise, execute S56, requesting the network device to send configuration information by sending the first request.

[0380] In the scheme of this application embodiment, for a SCell with activated on-demand SSB, when the SMTC configuration information for on-demand SSB is missing, if the SMTC configuration information for always-on SSB of the SCell exists and / or the SMTC configuration for always-on SSB of the SCell is completed, then the SMTC configuration information for always-on SSB is allowed to be used, that is, the SMTC configuration information is allowed to be reused. Always-on SSB is an SSB that is sent periodically.

[0381] In one possible implementation, the signaling carrying the first information is MAC CE signaling, which may include a fifth indication message. This fifth indication message indicates whether the use of always-on SSB SMTC configuration information is supported when the on-demand SSB SMTC configuration information is missing. The fifth indication message can occupy a 1-bit field. When the fifth indication message is the first content, it indicates that multiplexing is supported; when the fifth indication message is the second content, it indicates that multiplexing is not supported. The first content can be 1, and the second content can be 0; or, the first content can be 0, and the second content can be 1. It is understood that when the fifth indication message indicates that multiplexing is not supported, S56 is executed.

[0382] In one possible implementation, S59 can also be expressed as "UE determines whether the SMTC configuration of always-on SSB has been completed in advance".

[0383] S60: The UE uses SMTC configuration information with always-on SSB.

[0384] In summary, by utilizing the technical solution provided in this application, when there are one or more unconfigured items in the SMTC configuration of the on-demand SSB, the UE can supplement them using the relevant configuration information stored locally, or use the SMTC configuration information of the always-on SSB, or send a request to the network device to request the network device to supplement the relevant configuration information.

[0385] Similarly, in one possible implementation, in addition to reusing the SMTC configuration information of always-on SSB, the configuration information of always-on SSB can also be reused, as explained in detail below with reference to the accompanying drawings.

[0386] See Figure 17B, which is a flowchart of another communication method provided in an embodiment of this application.

[0387] The method includes the following steps:

[0388] S501: The network device sends the first information and the second information to the UE.

[0389] The second and first information can be carried in the same signaling message or in different signaling messages.

[0390] The second information includes activation instructions for the on-demand SSB. The first information includes relevant configuration information for the on-demand SSB and instructions related to that configuration.

[0391] S502: The UE determines the SCell that activates the on-demand SSB based on the second information, and determines that there is on-demand SSB configuration information that was not configured in the first information.

[0392] The SCell that activates the on-demand SSB can be one or more, and this application embodiment does not make specific limitations.

[0393] The UE needs to determine whether any on-demand SSB configuration information is missing for each SCell with an active on-demand SSB. In this implementation, the first indication information can indicate whether one or more of the on-demand SSB configuration information exists or is retained. For example, if only two of the information are indicated to exist, the remaining on-demand SSB configuration information is not configured in the first information and needs to use the configuration stored locally by the UE. The configuration stored locally by the UE can be configured using previous MAC CE signaling or RRC.

[0394] S503: The UE determines whether it has received on-demand SSB configuration information in advance.

[0395] If yes, execute S504; otherwise, execute S509.

[0396] S504: The UE determines whether the missing configuration information can be obtained based on the pre-received on-demand SSB configuration information.

[0397] In this application, missing configuration information refers to unconfigured content. The UE determines whether the missing configuration information can be obtained based on the latest configuration information stored locally. If yes, execute S505; otherwise, execute S506.

[0398] S505: Use the pre-received on-demand SSB configuration information.

[0399] S506: The UE sends the first request to the network device.

[0400] In this embodiment, the UE sends a first request to the network device to request the network device to configure the missing content in the on-demand SSB configuration information. This first request can be carried in MAC CE signaling, RRC, or Uplink control information (DCI); this embodiment does not specifically limit this. It is understood that the first request in this step, the first request in S44 of Figure 16, and the first request in S56 of Figure 17A can be the same request or different requests. When it is a single request, the UE, by sending the first request, requests the network device to simultaneously download the missing information in the SMTC configuration information of the on-demand SSB of the SCell corresponding to the Cell ID, as well as the missing information in the on-demand SSB configuration information, thus saving signaling.

[0401] The first request may include identifiers of SCells with missing configurations, i.e., Cell IDs. It is understood that these SCells with missing configurations are all SCells with active on-demand SSBs.

[0402] In one possible implementation, the first request may request the network device to send the complete on-demand SSB configuration information of the SCell corresponding to the Cell ID, so as to achieve a complete update of the on-demand SSB configuration information.

[0403] In another possible implementation, the first request can ask the network device to send the unconfigured content of the SCell corresponding to the Cell ID. For example, if the period is missing from the on-demand SSB configuration information, then only the network device is requested to resend the period to reduce the consumption of transmission resources. In this implementation, the first request can use fields to identify the specific missing information, similar to Figures 9A and 9B. For example, U0 corresponds to the period as the specific missing information, and U0 corresponds to the duration as the specific missing information.

[0404] S507: The UE receives the sixth information sent by the network device.

[0405] After receiving the first request, the network device sends a sixth message to the UE in response to the first request. The sixth message carries the unconfigured content of the SCell corresponding to each Cell ID. The sixth message can be MAC CE signaling, RRC, or DCI, and this embodiment does not specifically limit it. The sixth message in S507 and the sixth message in S57 of Figure 17A can be the same message or different messages. When they are the same message, they can be carried by the same signaling, saving signaling.

[0406] S508: The UE obtains on-demand SSB configuration information based on the sixth information sent by the network device.

[0407] After receiving the sixth message, the UE completes the information based on the on-demand SSB configuration information carried in the sixth message, ensuring that the on-demand SSB configuration information of each SCell that activates on-demand SSB is complete.

[0408] S509: The UE determines whether it has received always-on SSB configuration information in advance.

[0409] If yes, execute S600; otherwise, execute S506, requesting the network device to send unconfigured content by sending a first request.

[0410] In the scheme of this application embodiment, for a SCell that activates on-demand SSB, if on-demand SSB configuration information is missing, but always-on SSB configuration information of the SCell exists, the always-on SSB configuration information can be used, that is, the SMTC configuration information can be reused.

[0411] In one possible implementation, the signaling carrying the first information is MAC CE signaling, which may include a sixth indication message. This sixth indication message indicates whether always-on SSB configuration information is supported when on-demand SSB configuration information is missing. The sixth indication message can occupy a 1-bit field. When the sixth indication message is the first content, it indicates support for multiplexing; when the sixth indication message is the second content, it indicates that multiplexing is not supported. The first content can be 1, and the second content can be 0; or, the first content can be 0, and the second content can be 1. It is understood that when the sixth indication message indicates that multiplexing is not supported, S506 is executed.

[0412] In one possible implementation, S509 can also be expressed as "The UE determines whether the always-on SSB configuration has been completed in advance." S600: The UE uses the always-on SSB configuration information.

[0413] In summary, by utilizing the technical solution provided in this application embodiment, when there are one or more unconfigured items in the on-demand SSB configuration information, the UE can supplement it using the relevant configuration information stored locally, or send a request to the network device to request the network device to supplement the relevant configuration information.

[0414] The network device can also send a second message to the UE, instructing the UE to activate the on-demand SSB SCell. At this time, the UE can use the on-demand SSB configuration information pre-configured by RRC signaling, which will be explained in detail below with reference to the attached diagram.

[0415] Since the configuration information related to on-demand SSB can include on-demand SSB configuration information and on-demand SSB SMTC configuration information, the following first explains how the UE determines the on-demand SSB configuration information.

[0416] Referring to Figure 18, this figure is a flowchart of another communication method provided in an embodiment of this application.

[0417] The method includes the following steps:

[0418] S61: The UE sends a second message to the network device.

[0419] The second information includes activation indication information for the on-demand SSB, which can instruct the SCell to activate the on-demand SSB. In one possible implementation, the second information can also activate the SCell.

[0420] The second information is carried in the MAC CE signaling. A schematic diagram of the MAC CE signaling carrying the second information can be found in the description corresponding to Figure 13. The embodiments of this application will not be described again here.

[0421] S62: The UE determines the SCell to activate the on-demand SSB based on the second information.

[0422] The SCell that activates the on-demand SSB can be one or more, and this application embodiment does not make specific limitations.

[0423] S63: The UE has determined that it has not received on-demand SSB configuration information in advance.

[0424] In one possible implementation, the network device may send a fifth message to the UE, indicating at least one set of on-demand SSB configuration information. For each set of on-demand SSB configuration information, this may include on-demand SSB configuration information and / or the on-demand SSB's SMTC configuration information.

[0425] In another possible implementation, the network device can send a fifth piece of information to the UE, which indicates a list of at least one of the following related configuration information for the on-demand SSB: an SSB configuration identifier list, an on-demand SSB period list, an on-demand SSB activation time list, an on-demand SSB burst count list, an SSB frequency list, an SSB subcarrier spacing list, and an SSB subcarrier spacing list. When the on-demand SSB of an SCell is activated, the UE can determine the on-demand SSB configuration information for that SCell based on the list of contents.

[0426] The fifth message can be carried in the first signaling, which can be a MAC CE or RRC signaling. However, in practical applications, when the UE receives the second message, it may not have received the fifth message yet, so the UE does not store the on-demand SSB configuration information locally.

[0427] The UE needs to determine whether there is a missing on-demand SSB configuration information for each SCell that has an active on-demand SSB.

[0428] S64: The UE sends the first request to the network device.

[0429] In this embodiment, the UE sends a first request to the network device to request the network device to configure missing information in the on-demand SSB configuration information. This first request may be carried in MAC CE signaling, or in RRC, or in uplink control information (DCI), and this embodiment does not specifically limit the scope.

[0430] The first request may include the identifier of the SCell with missing configuration, i.e., the Cell ID.

[0431] In one possible implementation, the first request may request the network device to send the complete on-demand SSB configuration of the SCell corresponding to the Cell ID, so as to achieve a complete update of the configuration information.

[0432] In another possible implementation, the first request can request the network device to send missing information for the SCell corresponding to the Cell ID. For example, if the on-demand SSB period is missing, then only the on-demand SSB period needs to be resent to reduce the consumption of transmission resources. In this implementation, the first request can use field U to identify the specific missing information, similar to the methods shown in Figures 9A and 9B.

[0433] S65: The network device sends the sixth message to the UE.

[0434] After receiving the first request, the network device sends a sixth message to the UE in response to the first request. The sixth message carries the missing information of the SCell corresponding to each Cell ID. The sixth message can be MAC CE signaling, RRC, or Downlink Control Information (DCI), and this embodiment does not specifically limit it.

[0435] S66: The UE obtains the on-demand SSB configuration information based on the sixth information.

[0436] After receiving the sixth message, the UE completes the information based on the on-demand SSB configuration information carried in the sixth message, ensuring that the on-demand SSB configuration information of each SCell that activates on-demand SSB is complete.

[0437] The specific implementation methods of the signaling carrying the second information, the signaling carrying the sixth information, and the signaling of the first request can be found in the description of the above embodiments, and will not be repeated here.

[0438] The following describes how the UE determines the SMTC configuration information for the on-demand SSB.

[0439] Referring to Figure 19A, this figure is a flowchart of another communication method provided in an embodiment of this application.

[0440] The method includes the following steps:

[0441] S71: The network device sends a second message to the UE.

[0442] The second piece of information includes activation instructions for the on-demand SSB.

[0443] S72: The UE determines the SCell to activate the on-demand SSB based on the second information.

[0444] The SCell that activates the on-demand SSB can be one or more, and this application embodiment does not make specific limitations.

[0445] S73: The UE determines whether it has received the SMTC configuration information from the on-demand SSB in advance.

[0446] The UE needs to determine for each SCell that has an active on-demand SSB whether there is missing SMTC configuration information for the on-demand SSB. If so, execute S74; otherwise, execute S79.

[0447] In one possible implementation, the network device may send a fifth message to the UE, indicating at least one set of on-demand SSB configuration information. For each set of on-demand SSB configuration information, this may include on-demand SSB configuration information and / or the on-demand SSB's SMTC configuration information.

[0448] The fifth message can be carried in the first signaling, which can be a MAC CE or RRC signaling. However, in practical applications, when the UE receives the second message, it may not have received the fifth message yet, so the UE does not store the on-demand SSB SMTC configuration information locally.

[0449] S74: The UE determines whether the SMTC configuration information received in advance on-demand SSB is complete.

[0450] If yes, execute S75; otherwise, execute S76.

[0451] S75: Use the SMTC configuration information of the pre-received on-demand SSB.

[0452] S76: The UE sends the first request to the network device.

[0453] In this embodiment, the UE sends a first request to the network device, requesting the network device to configure the unconfigured content in the SMTC configuration information of the on-demand SSB. This first request may be carried in the MAC CE signaling, or in the RRC, or in the uplink control information (DCI), and this embodiment does not specifically limit it.

[0454] It is understandable that the first request in this step and the first request in S64 of Figure 18 can be the same request or different requests. When they are the same request, the UE sends the first request to request the network device to simultaneously remove the missing information in the SMTC configuration information of the on-demand SSB of the SCell corresponding to the Cell ID, as well as the missing information in the on-demand SSB configuration information.

[0455] The first request may include identifiers of SCells with missing configurations, i.e., Cell IDs. It is understood that these SCells with missing configurations are all SCells with active on-demand SSBs.

[0456] In one possible implementation, the first request may request the network device to send the complete on-demand SSB SMTC configuration information for the SCell corresponding to the Cell ID, so as to achieve a complete update of the on-demand SSB SMTC configuration information.

[0457] In another possible implementation, the first request can request the network device to send missing information for the SCell corresponding to the Cell ID. For example, if the measurement window period is missing from the SMTC configuration information of the on-demand SSB, then only the measurement window period needs to be resent to the network device, thus reducing the consumption of transmission resources. In this implementation, the first request can use fields to identify the specific missing information, similar to those in Figures 9C and 9D. For example, U2 corresponds to the period of the SMTC configuration information, U3 corresponds to the duration of the SMTC configuration information, and U4 corresponds to the offset of the SMTC configuration information.

[0458] S77: The UE receives the sixth information sent by the network device.

[0459] After receiving the first request, the network device sends a sixth message to the UE in response to the first request. The sixth message carries missing information for the SCell corresponding to each Cell ID. The sixth message can be MAC CE signaling, RRC, or DCI, and this embodiment does not specifically limit it.

[0460] S78: The UE obtains the SMTC configuration information of the on-demand SSB based on the sixth information sent by the network device.

[0461] After receiving the sixth message, the UE completes the information based on the SMTC configuration information of the on-demand SSB carried in the sixth message, ensuring that the SMTC configuration information of the on-demand SSB of each SCell that activates the on-demand SSB is complete.

[0462] S79: The UE determines whether it has received the SMTC configuration information of always-on SSB in advance.

[0463] In the scheme of this application embodiment, for a SCell that activates on-demand SSB, if the SMTC configuration information of on-demand SSB is not received in advance, and if the SMTC configuration information of always-on SSB of the SCell exists and / or the SMTC configuration of always-on SSB of the SCell is completed, then the SMTC configuration information of always-on SSB is allowed to be used, that is, the SMTC configuration information is allowed to be reused.

[0464] In one possible implementation, the signaling carrying the second information is MAC CE signaling, which may include a seventh indication information. This seventh indication information indicates whether the use of always-on SSB SMTC configuration information is supported when the on-demand SSB SMTC configuration information is missing. The seventh indication information can occupy a 1-bit field. When the seventh indication information is the first content, it indicates that multiplexing is supported; when the seventh indication information is the second content, it indicates that multiplexing is not supported. The first content can be 1, and the second content can be 0; or, the first content can be 0, and the second content can be 1. It is understood that when multiplexing is not supported, S76 is executed.

[0465] In one possible implementation, S79 can also be expressed as "UE determines whether the SMTC configuration of always-on SSB has been completed in advance".

[0466] If yes, execute S80; otherwise, execute S76, requesting the network device to send configuration information by sending the first request.

[0467] S80: The UE uses SMTC configuration information with always-on SSB.

[0468] In summary, by utilizing the technical solution provided in the embodiments of this application, the supplementation of SMTC configuration information for on-demand SSB is flexibly realized.

[0469] Similarly, in one possible implementation, in addition to reusing the SMTC configuration information of always-on SSB, the configuration information of always-on SSB can also be reused, as explained in detail below with reference to the accompanying drawings.

[0470] Referring to Figure 19B, this figure is a flowchart of another communication method provided in an embodiment of this application.

[0471] The method includes the following steps:

[0472] S81: The network device sends a second message to the UE.

[0473] The second piece of information includes activation instructions for the on-demand SSB.

[0474] S82: The UE determines the SCell to activate the on-demand SSB based on the second information.

[0475] The SCell that activates the on-demand SSB can be one or more, and this application embodiment does not make specific limitations.

[0476] S83: The UE determines whether it has received on-demand SSB configuration information in advance.

[0477] The UE needs to determine for each SCell that has activated on-demand SSB whether there is missing on-demand SSB configuration information. If so, execute S84; otherwise, execute S89.

[0478] The fifth message can be carried in the first signaling, which can be a MAC CE or RRC signaling. However, in practical applications, when the UE receives the second message, it may not have received the fifth message yet, so the UE does not store the on-demand SSB configuration information locally.

[0479] S84: The UE determines whether the pre-received on-demand SSB configuration information is complete.

[0480] If yes, execute S85; otherwise, execute S86.

[0481] S85: Use the pre-received on-demand SSB configuration information.

[0482] S86: The UE sends the first request to the network device.

[0483] In this embodiment, the UE sends a first request to the network device to request the network device to configure unconfigured content in the on-demand SSB configuration information. This first request may be carried in MAC CE signaling, or in RRC, or in uplink control information (DCI), and this embodiment does not specifically limit the scope.

[0484] It is understandable that the first request in this step and the first request in S76 of Figure 19A can be the same request or different requests. When they are the same request, the UE sends the first request to request the network device to simultaneously remove the missing information in the SMTC configuration information of the on-demand SSB of the SCell corresponding to the Cell ID, as well as the missing information in the on-demand SSB configuration information.

[0485] The first request may include identifiers of SCells with missing configurations, i.e., Cell IDs. It is understood that these SCells with missing configurations are all SCells with active on-demand SSBs.

[0486] In one possible implementation, the first request may request the network device to send the complete on-demand SSB configuration information of the SCell corresponding to the Cell ID, so as to achieve a complete update of the on-demand SSB configuration information.

[0487] In another possible implementation, the first request can request the network device to send missing information for the SCell corresponding to the Cell ID. For example, if the measurement window period is missing from the SMTC configuration information of the on-demand SSB, then only the measurement window period needs to be resent to the network device, thus reducing the consumption of transmission resources. In this implementation, the first request can use fields to identify the specific missing information, similar to those in Figures 9A and 9B. For example, U0 corresponds to the specific missing information period, and U1 corresponds to the specific missing information duration.

[0488] S87: The UE receives the sixth information sent by the network device.

[0489] After receiving the first request, the network device sends a sixth message to the UE in response to the first request. The sixth message carries the unconfigured content of the SCell corresponding to each Cell ID. The sixth message can be MAC CE signaling, RRC, or DCI, and this embodiment does not specifically limit it. The first message and the sixth message in S77 can be the same.

[0490] S88: The UE obtains on-demand SMTC configuration information based on the sixth information sent by the network device.

[0491] After receiving the sixth message, the UE completes the information based on the on-demand SSB configuration information carried in the sixth message, ensuring that the on-demand SSB configuration information of each SCell that activates on-demand SSB is complete.

[0492] S89: The UE determines whether it has received always-on SSB configuration information in advance.

[0493] In the scheme of this application embodiment, for a SCell that activates on-demand SSB, if the SCell has always-on SSB configuration information and / or the SCell has completed always-on SSB configuration, the always-on SSB configuration information can be used if the SCell has always-on SSB configuration information and / or the SCell has completed always-on SSB configuration. That is, the SMTC configuration information can be reused.

[0494] In one possible implementation, the signaling carrying the second information is MAC CE signaling, which may include an eighth indication message. This eighth indication message indicates whether always-on SSB configuration information is supported when on-demand SSB configuration information is missing. The eighth indication message can occupy a 1-bit field. When the eighth indication message is the first content, it indicates that multiplexing is supported; when the eighth indication message is the second content, it indicates that multiplexing is not supported. The first content can be 1, and the second content can be 0; or, the first content can be 0, and the second content can be 1. It is understood that when multiplexing is not supported, S76 is executed.

[0495] In one possible implementation, S89 can also be expressed as "UE determines whether the always-on SSB configuration has been completed in advance".

[0496] If yes, execute S90; otherwise, execute S86, requesting the network device to send configuration information by sending the first request.

[0497] S90: The UE uses always-on SSB configuration information.

[0498] In summary, the technical solution provided by the embodiments of this application flexibly realizes the supplementation of on-demand SSB configuration information.

[0499] Based on the communication methods provided in the above embodiments, this application also provides a network device, which will be described in detail below with reference to the accompanying drawings.

[0500] Referring to Figure 20, this figure is a schematic diagram of a network device provided in an embodiment of this application.
