The CU-DU structure can split the protocol layers of the access network device, with some protocol layer functions being controlled by the CU, and the remaining or all protocol layer functions being distributed in the DU and controlled by the CU, but is not limited thereto.
[0110] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions proposed in the embodiments of the present disclosure. It can be known by those skilled in the art that, as the system architecture evolves and new business scenarios appear, the technical solutions proposed in the embodiments of the present disclosure are also applicable to similar technical problems.
[0111] The following embodiments of the present disclosure can be applied to the communication system 100 shown in FIG. 1, or part of the subjects, but are not limited thereto. The subjects shown in FIG. 1 are illustrative, and the communication system can include all or part of the subjects in FIG. 1, or other subjects other than those in FIG. 1. The number and form of each subject is arbitrary, each subject can be physical or virtual, the connection relationship between each subject is illustrative, each subject can not be connected or can be connected, and the connection can be in any manner, can be direct connection or indirect connection, can be wired connection or wireless connection.
[0112] Embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (Bluetooth (registered trademark)), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), system using other communication methods, next-generation system expanded based thereon, and the like. Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).
[0113] It should be noted that, with the pursuit of rate, delay, high-speed mobility, energy efficiency, and the diversity and complexity of services in future life, the 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) international standard organization begins to develop 5G. The main application scenarios of 5G are: enhanced mobile broadband (Enhanced Mobile Broadband, eMBB), low latency and high reliability communication (Ultra-Reliable Low-Latency Communications, URLLC), and massive machine type communication (Massive Machine Type Communication, mMTC). eMBB still aims to provide users with multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB can be deployed in different scenarios, such as indoor, urban, rural, etc., the difference between its capabilities and requirements is also relatively large, so it cannot be generalized and must be analyzed in detail in combination with the specific deployment scenario. Typical applications of URLLC include: industrial automation, power automation, remote medical operation (surgery), traffic safety assurance, etc. The typical characteristics of mMTC include: high connection density, small data volume, delay-insensitive service, low-cost module and long service life, etc.
[0114] Since the energy consumption of a 5G base station is four times that of an LTE base station, network energy saving is an important means for operators to reduce the cost of operating a 5G system. In some embodiments, in order to save energy for terminals in RRC_CONNECTED state, a WUS (wake up signal) is introduced. An offset before the on duration of UE C-DRX (Connected Discontinuous Reception) defines a duration for sending a WUS signal, and a WUS signal, i.e. DCI format 2-6, scrambled by PS-RNTI (Power Saving RNTI) is sent during the WUS duration, which is used to indicate whether the terminal wakes up to listen to the PDCCH (Physical Downlink Control Channel) during the next UE C-DRX on duration.
[0115] In some embodiments, in order to save power for RRC_IDLE / INACTIVE terminals, paging WUS (paging wake-up signal) is introduced. That is, paging WUS, i.e., PEI (paging early indication), is sent at a certain time before PO (paging occasion), which is used to indicate whether the terminal listens to the paging scheduling information in the PO. The PEI is a DCI format 2-7 scrambled by PEI-RNTI (paging early indication radio network temporary identifier).
[0116] In some embodiments, NES (network energy saving) has supported SSB-less SCell in the inter-band CA scenario. The SSB-less SCell does not send SSB (synchronization signal block), and the terminal achieves time-frequency synchronization on the SCell (secondary cell) through the SSB of the reference cell, L1 / L3 (layer 1 / layer 3) measurement, SCell activation, and other functions. However, SSB-less in the inter-band CA scenario has many limitations, such as PCell (primary cell) and SCell co-located and only working in frequency band FR1. Frequency band FR2 and non-co-located scenarios are not supported.
[0117] In some embodiments, R19 NES supports FR2 and non-co-located scenarios, and on demand SSB can be used as an enhancement to SSB transmission for scenarios not covered by SSB-less operation to achieve network element gains and ensure proper / enhanced SCell functions, including time / frequency synchronization, L1 / L3 measurement, and SCell activation. If the terminal needs to obtain the SSB of the on-demand SSB SCell, it can request the SSB of the on-demand SSB SCell through the UL WUS (wake-up signal). That is, the SSB of the SCell is sent based on the request, or on demand. Another possible implementation is that the network device triggers the sending of the SSB on the SCell based on the implementation, for example, the network device needs to obtain the RRM (radio resource management) measurement report of the SCell, and the network device needs to notify the terminal through the indication information.
[0118] In some embodiments, as shown in FIG. 2, on demand SSB can be applied to the following three scenarios: scenario 1, adding an SCell but not activating the SCell yet; scenario 2, during SCell activation; scenario 3, after SCell activation. Exemplarily, in any of the above scenarios (such as scenario 1, or scenario 2, or scenario 3), the on-demand SSB SCell can trigger the sending of SSB based on the network, and the network device can indicate the terminal to activate / use which SSB configuration through indication information.
[0119] It should be noted that, in order to support request-based SSB, the network device also needs to provide the SSB configuration associated with the on-demand SSB SCell. In some embodiments, in the case of supporting multiple SSB configurations, the network device also needs to indicate the terminal to activate / use which SSB configuration when activating SSB transmission. However, how to activate / use which SCell and / or which SSB configuration of the SCell has become a problem to be solved.
[0120] To this end, the embodiments of the present disclosure provide a communication method and device, which can solve the problem of how to activate / use which SCell and / or which SSB configuration of the SCell in the case of supporting multiple SSB configurations, thereby improving the stability and accuracy of communication, ensuring the synchronization between the terminal and the network device, and optimizing the network performance.
[0121] FIG. 3A is an interaction schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 3A, the embodiments of the present disclosure relate to a communication method applicable to the communication system 100, and the above method includes but is not limited to the following steps.
[0122] Step S3101, sending first information.
[0123] In some embodiments, the first information can be used to indicate a first SSB configuration, wherein the first SSB configuration is a SSB configuration of a first secondary cell (SCell), and the first SSB configuration can be at least one SSB configuration of one or more SSB configurations associated with the first SCell, e.g., the first SSB configuration can be one SSB configuration of the one or more SSB configurations associated with the first SCell, or the first SSB configuration can be a plurality of SSB configurations of the one or more SSB configurations associated with the first SCell. For example, in some embodiments, the first SCell is associated with a plurality of SSB configurations, and the first SSB configuration can be one SSB configuration of the plurality of SSB configurations associated with the first SCell. Further, the first information can be used to indicate an activation status of the first SSB configuration, and the activation status can include deactivation and activation, e.g., the first information can be used to indicate that the activation status of the first SSB configuration is activation, or the first information can be used to indicate that the first SSB configuration is activated, or the first information can be used to indicate to activate the first SSB configuration. For example, the first information can be used to indicate that the activation status of the first SSB configuration is deactivation, or the first information can be used to indicate that the first SSB configuration is deactivated, or the first information can be used to indicate to deactivate the first SSB configuration.
[0124] In some embodiments, the first information can be used to indicate a SSB configuration of a SCell supporting on-demand request, which can also be referred to as an on-demand SSB SCell. The SSB configuration can be a SSB configuration of the on-demand SSB SCell. For example, the on-demand SSB SCell is associated with a plurality of SSB configurations, and the first information can be used to indicate one or more SSB configurations of the plurality of SSB configurations, e.g., the first information can indicate one SSB configuration of the plurality of SSB configurations. Further, the first information can be used to indicate an activation status of the SSB configuration of the on-demand SSB SCell, and the activation status can include deactivation and activation, e.g., the first information can indicate the activation status of one SSB configuration of the plurality of SSB configurations associated with the on-demand SSB SCell.
[0125] In some embodiments, the first information can be used to indicate an activation state of SSB transmission of the first SCell. For example, the first information can be used to indicate that the activation state of SSB transmission of the first SCell is deactivated, or the first information can be used to indicate that SSB transmission of the first SCell is deactivated, or the first information can be used to indicate to deactivate SSB transmission of the first SCell. For example, the first information can be used to indicate that the activation state of SSB transmission of the first SCell is activated, or the first information can be used to indicate that SSB transmission of the first SCell is activated, or the first information can be used to indicate to activate SSB transmission of the first SCell.
[0126] In some embodiments, the first information can be used to indicate an activation state of SSB transmission of the first SCell. For example, the first information can be used to indicate that the activation state of SSB transmission of the first SCell is deactivated, or the first information can be used to indicate that SSB transmission of the first SCell is deactivated, or the first information can be used to indicate to deactivate SSB transmission of the first SCell. For example, the first information can be used to indicate that the activation state of SSB transmission of the first SCell is activated, or the first information can be used to indicate that SSB transmission of the first SCell is activated, or the first information can be used to indicate to activate SSB transmission of the first SCell.
[0127] In some embodiments, the terms of “SSB transmission”, “SSB sending” and the like can be replaced with each other.
[0128] In some embodiments, the first information can be sent by the network device 102 to the terminal 101. For example, the network device 102 sends the first information to the terminal 101, and the terminal 101 receives the first information sent by the network device 102. For example, the first information can indicate whether to activate the SSB transmission of the first SCell, or the first information can indicate the activation state of the SSB transmission of the first SCell, such as indicating that the activation state of the SSB transmission of the first SCell is activated, or indicating that the activation state of the SSB transmission of the first SCell is deactivated. For example, the first information can indicate the activation state of the first SSB configuration in the one or more SSB configurations associated with the first SCell, such as indicating that the first SSB configuration in the one or more SSB configurations associated with the first SCell is activated, or indicating that the first SSB configuration in the one or more SSB configurations associated with the first SCell is deactivated. For example, the first information can indicate that the SSB transmission of the first SCell is activated, and the first SSB configuration in the one or more SSB configurations associated with the first SCell is activated.
[0129] In some embodiments, the first information can include a first parameter, the first parameter is associated with an SSB configuration, and the first parameter can be used to indicate the activation state of the associated SSB configuration. In some embodiments, the number of first parameters included in the first information can be the same as the number of SSB configurations associated with the first SCell. For example, the first information can include one or more first parameters, each first parameter is associated with an SSB configuration, the one or more first parameters are associated with the one or more SSB configurations associated with the first SCell, and each first parameter can be used to indicate the activation state of the corresponding SSB configuration; wherein the first SCell can be a cell supporting on-demand SSB request. In some embodiments, the association between the first parameter and the SSB configuration can be understood as that there is a mapping relationship between the SSB configuration and the first parameter, that is, one SSB configuration corresponds to one first parameter, and the first parameter can indicate the activation state of the SSB configuration associated with the first parameter.
[0130] In some embodiments, the first information can indicate an activation state of the first SSB configuration. For example, the first information can include a first parameter associated with the first SSB configuration, and the first parameter can indicate an activation state of the first SSB configuration associated with the first parameter. The activation state can include activation or deactivation. The first SSB configuration can be one of a plurality of SSB configurations associated with the first SCell. In one possible implementation, the number of first parameters included in the first information can be the same as the number of SSB configurations associated with the first SCell. For example, the first information can include one or more first parameters. If the value of the first parameter associated with the first SSB configuration in the one or more first parameters is a first value, it can indicate that the activation state of the first SSB configuration is activated. If the value of the first parameter associated with the first SSB configuration in the one or more first parameters is a second value, it can indicate that the activation state of the first SSB configuration is deactivated.
[0131] In some embodiments, the first information described above can include but is not limited to RRC signaling. For example, the first information can be RRC signaling, and the first parameters described above can be included in the RRC signaling. Each first parameter can be associated with an SSB configuration, and the first parameter can be used to indicate the activation state of the associated SSB configuration. The number of first parameters included in the first information can be the same as the number of SSB configurations associated with the first SCell. For example, the first information can include one or more first parameters, each first parameter is associated with an SSB configuration, the SSB configurations associated with the one or more first parameters are the one or more SSB configurations associated with the first SCell, and each first parameter can be used to indicate the activation state of the corresponding SSB configuration. In some embodiments, the association between the first parameter and the SSB configuration can be understood as a mapping relationship between the SSB configuration and the first parameter, i.e., one SSB configuration corresponds to one first parameter, and the first parameter can indicate the activation state of the SSB configuration associated with the first parameter.
[0132] In some embodiments, the first SSB configuration can include but is not limited to related parameters of SSB transmission, such as the period of SSB, the frequency / band of SSB, the start and end positions of SSB, etc. For example, in the case where the first SCell triggers the sending of SSB based on the network, the network device can activate the SSB transmission of the first SCell and activate at least one of the plurality of SSB configurations associated with the first SCell through the first parameter. For example, the network device determines to deactivate the SSB transmission of the first SCell, such as the network device determines to deactivate the SSB transmission of the first SCell based on the implementation, and then the network device can deactivate the SSB transmission of the first SCell through the first parameter.
[0133] In some embodiments, the first parameter can be configured in SSB configuration granularity (i.e., the first parameter can be configured in units of SSB configuration), for example, each SSB configuration corresponds to a first parameter, for example, the first parameter is included in the SSB configuration. For example, the network device indicates the activation state of the first SSB configuration in one or more SSB configurations associated with the first SCell, the first SSB configuration can include the first parameter, and the value of the first parameter can determine the activation state of the first SSB configuration associated with the first parameter. For example, the first parameter can be a high-layer parameter in RRC signaling. The first SCell can be associated with one or more SSB configurations, each SSB configuration corresponds to a first parameter, in the case of multiple SSB configurations associated with the first SCell, the network device activates or deactivates the SSB transmission of the first SCell through the first parameter corresponding to each SSB configuration in the multiple SSB configurations, and can activate or deactivate the corresponding SSB configuration through the first parameter corresponding to each SSB configuration in the multiple SSB configurations. In some embodiments, the multiple SSB configurations associated with the first SCell can be understood as the multiple SSB configurations configured for the first SCell, i.e., the network device configures the multiple SSB configurations for the first SCell.
[0134] In some embodiments, the value range of the first parameter can be two values, and the activation or deactivation of the SSB configuration (such as the first SSB configuration) associated with the first parameter can be indicated by the different values of the first parameter. For example, the value of the first parameter is the first value, indicating that the SSB configuration associated with the first parameter is activated, and the value of the first parameter is the second value, indicating that the SSB configuration associated with the first parameter is deactivated. For example, the first value can be 1, and the second value can be 0; or the first value can be activated, and the second value can be deactivated, or the first value and the second value use other value modes, which are not limited by the present disclosure, and will not be described here. In some embodiments, the terms “activate”, “use” and the like can be replaced with each other; the terms “deactivate”, “not use”, “not activate” and the like can be replaced with each other.
[0135] It should be noted that in some embodiments, the network device 102 can indicate the activation state of the SSB transmission of the first SCell through the first parameter, for example, if the first parameter corresponding to at least one of the one or more SSB configurations associated with the first SCell indicates activation (i.e., the value of the first parameter corresponding to at least one of the one or more SSB configurations associated with the first SCell is the first value), it can be indicated that the first SCell activates the SSB transmission and transmits the SSB using the SSB configuration associated with the first parameter, that is, if the first parameter corresponding to at least one of the one or more SSB configurations associated with the first SCell indicates activation, it can be indicated that the SSB transmission of the first SCell is activated and the SSB configuration associated with the first parameter is activated. For another example, if the first parameter corresponding to each of the one or more SSB configurations associated with the first SCell indicates deactivation (i.e., the value of the first parameter corresponding to each of the one or more SSB configurations associated with the first SCell is the second value), it indicates that the first SCell deactivates the SSB transmission, that is, it can be indicated that the SSB transmission of the first SCell is deactivated.
[0136] In a possible implementation, the number of first parameters included in the first information can be the same as the number of SSB configurations associated with the first SCell. For example, the first information can include one or more first parameters, each first parameter being associated with an SSB configuration, the SSB configuration associated with the one or more first parameters being the one or more SSB configurations associated with the first SCell, and each first parameter can be used to indicate the activation state of the corresponding SSB configuration. In this way, the terminal can determine the activation state of the SSB transmission of the first SCell according to the one or more first parameters included in the first information.
[0137] For example, taking the first SCell associated with multiple SSB configurations of SSB configuration 0, SSB configuration 1, SSB configuration 2 and SSB configuration 3 as an example, each SSB configuration corresponds to a first parameter, in the case that the first SCell triggers the sending of SSB based on the network, the network device 102 can activate the SSB transmission of the first SCell and activate the SSB configuration associated with the first parameter through the first parameter corresponding to each SSB configuration of the four SSB configurations associated with the first SCell. For example, the network device 102 sets the value of the first parameter corresponding to the SSB configuration 0 as a first value (such as 1), and the SSB configuration 0 is the first SSB configuration. The values of the first parameters corresponding to the SSB configuration 1, SSB configuration 2 and SSB configuration 3 are set as a second value (such as 0), which indicates that the SSB transmission of the first SCell is activated and the SSB configuration 0 (i.e. the first SSB configuration) is activated, and the SSB configuration 1, SSB configuration 2 and SSB configuration 3 are deactivated. For another example, the network device determines to deactivate the SSB transmission of the first SCell, for example, the network device determines to deactivate the SSB transmission of the first SCell based on the implementation, and the network device 102 can deactivate the SSB transmission of the first SCell through the first parameter, that is, the network device 102 can set the values of the first parameters corresponding to the SSB configuration 0, SSB configuration 1, SSB configuration 2 and SSB configuration 3 as the second value, which indicates that the SSB transmission of the first SCell is deactivated.
[0138] Optionally, in some embodiments, as shown in FIG. 3A, the method can further include step S3102.
[0139] Step S3102, determining the activation state of the first SSB configuration according to the first parameter.
[0140] In some embodiments, the terminal 101 can determine, according to the first parameter, that the activation state of the first SSB configuration is activated or deactivated. For example, the first parameter is associated with the first SSB configuration, and the first SSB configuration can be one of the multiple SSB configurations associated with the first SCell, which can be a cell supporting on-demand request. For example, the first SSB configuration includes the first parameter, and the terminal 101 can determine, according to the value of the first parameter, that the activation state of the first SSB configuration associated with the first parameter is activated or deactivated. For example, the terminal 101 receives the first information sent by the network device 102, the first information includes the above-mentioned first parameter, and the terminal 101 can determine the activation state of the first SSB configuration associated with the first parameter according to the value of the first parameter. For example, the terminal 101 determines that the value of the first parameter is a first value, and then determines that the activation state of the first SSB configuration associated with the first parameter is activated. For example, the terminal 101 determines that the value of the first parameter is a second value, and then determines that the activation state of the first SSB configuration associated with the first parameter is deactivated. For example, the first value can be 1, and the second value can be 0; or the first value can be activated, and the second value can be deactivated, or the first value and the second value use other value modes, which are not limited in the present disclosure and will not be described here.
[0141] In some embodiments, the number of first parameters included in the first information can be the same as the number of SSB configurations associated with the first SCell. For example, the first information can include one or more first parameters, each first parameter is associated with an SSB configuration, the one or more first parameters are associated with one or more SSB configurations associated with the first SCell, and each first parameter can be used to indicate the activation state of the corresponding SSB configuration; wherein the first SCell can be a cell supporting on-demand request SSB. For example, the activation state of the first SSB configuration can be determined according to the value of the first parameter associated with the first SSB configuration in the one or more first parameters.
[0142] Optionally, in some embodiments, as shown in FIG. 3A, the method can further include step S3103.
[0143] In step S3103, the activation state of the SSB transmission of the first SCell is determined according to the first parameter, and the activation state can include activated or deactivated.
[0144] In some embodiments, the terminal 101 receives the first information sent by the network device 102, which can include the first parameters described above. The terminal 101 can determine the activation state of the SSB transmission of the first SCell according to the first parameters. For example, the terminal 101 can determine the activation state of the SSB transmission of the first SCell according to the number of the first parameters included in the first information and the value of each first parameter.
[0145] In some embodiments, the number of the first parameters included in the first information can be the same as the number of the SSB configurations associated with the first SCell. For example, the first information can include one or more first parameters, each of which is associated with an SSB configuration. The SSB configurations associated with the one or more first parameters are one or more SSB configurations associated with the first SCell. Each first parameter can be used to indicate the activation state of the corresponding SSB configuration. The first SCell can be a cell that supports on-demand SSB request. For example, the activation state of the SSB transmission of the first SCell can be determined according to the one or more first parameters. For example, if at least one of the one or more first parameters indicates that the corresponding SSB configuration is activated, it can be determined that the activation state of the SSB transmission of the first SCell is activated. Or, if each of the one or more first parameters indicates that the corresponding SSB configuration is deactivated, it can be determined that the activation state of the SSB transmission of the first SCell is deactivated.
[0146] In some embodiments, the terminal 101 can determine to activate the SSB transmission of the first SCell if at least one of the first parameters corresponding to the one or more SSB configurations associated with the first SCell indicates activation (i.e., the value of the first parameter corresponding to at least one of the one or more SSB configurations associated with the first SCell is the first value). For example, assuming that the first SCell is associated with four SSB configurations, i.e., SSB configuration 0, SSB configuration 1, SSB configuration 2 and SSB configuration 3, each of which corresponds to a first parameter, e.g., SSB configuration 0 corresponds to first parameter 0, SSB configuration 1 corresponds to first parameter 1, SSB configuration 2 corresponds to first parameter 2, and SSB configuration 3 corresponds to first parameter 3, in the case that the network device 102 triggers the first SCell to send SSBs based on the network, the network device 102 can activate the SSB transmission of the first SCell and activate the SSB configuration associated with the first parameter by the first parameter corresponding to each of the four SSB configurations associated with the first SCell. For example, the network device 102 sets the value of the first parameter corresponding to SSB configuration 0 to the first value (e.g., 1) and sets the value of the first parameter corresponding to each of SSB configuration 1, SSB configuration 2 and SSB configuration 3 to the second value (e.g., 0). After the terminal 101 receives the first information sent by the network device 102, the terminal 101 determines that there are four first parameters (e.g., first parameter 0, first parameter 1, first parameter 2 and first parameter 3) in the first information, the value of first parameter 0 is the first value (i.e., first parameter 0 indicates activation), and the terminal 101 can determine that the activation state of the SSB transmission of the first SCell is activation and the activation state of SSB configuration 0 is activation; the values of first parameter 1, first parameter 2 and first parameter 3 are the second value (i.e., first parameter 1, first parameter 2 and first parameter 3 indicate deactivation), and the terminal 101 can determine that the activation states of first SSB configuration 1, first SSB configuration 2 and first SSB configuration 3 are deactivation.
[0147] In some embodiments, if the first parameter corresponding to each of the one or more SSB configurations associated with the first SCell indicates deactivation (i.e., the value of the first parameter corresponding to each of the one or more SSB configurations associated with the first SCell is the second value), the terminal 101 can determine that the activation state of the SSB transmission of the first SCell is deactivation. For example, assuming that the first SCell is associated with multiple SSB configurations, such as SSB configuration 0, SSB configuration 1, SSB configuration 2, and SSB configuration 3, each of which corresponds to a first parameter, such as first parameter 0, first parameter 1, first parameter 2, and first parameter 3, respectively, and the network device determines to deactivate the SSB transmission of the first SCell, such as the network device determines to deactivate the SSB transmission of the first SCell based on implementation, the network device 102 can deactivate the SSB transmission of the first SCell by the first parameters, i.e., the network device 102 can set the value of each of the first parameters corresponding to the SSB configuration 0, SSB configuration 1, SSB configuration 2, and SSB configuration 3 to the second value. The terminal 101 receives the first information sent by the network device 102, and the terminal 101 determines that there are four first parameters (such as the first parameter 0, first parameter 1, first parameter 2, and first parameter 3) in the first information, and the value of each of the first parameter 0, first parameter 1, first parameter 2, and first parameter 3 is the second value, and the terminal 101 can determine that the activation state of the SSB transmission of the first SCell is deactivation.
[0148] It should be noted that in some embodiments, the above steps S3102 and S3103 can be a parallel scheme. For example, the step S3101 + the step S3102 can be implemented as an independent embodiment, and the step S3101 + the step S3103 can be implemented as an independent embodiment.
[0149] It is also to be noted that, in some embodiments, the first parameter can be configured to the terminal 101 by the network device 102 together with the SSB configuration, i.e., the network device 102 can configure the first parameter associated with each of the plurality of SSB configurations of the first SCell to the terminal 101 when configuring the plurality of SSB configurations of the first SCell to the terminal 101, so as to reduce the number of interactions between the network and the terminal. In some embodiments, the first parameter can not be configured to the terminal 101 together with the SSB configuration, i.e., the plurality of SSB configurations of the first SCell and the first parameter (i.e., the first parameter associated with each of the plurality of SSB configurations) can be configured to the terminal 101 separately by the network device 102 (e.g., configured to the terminal 101 by different pieces of RRC signaling), for example, the network device 102 can first configure the plurality of SSB configurations of the first SCell to the terminal 101, and then configure the first parameter associated with each of the plurality of SSB configurations to the terminal 101.
[0150] It is to be noted that, in some embodiments, when the network device 102 activates the SSB transmission of the first SCell and activates the first SSB configuration of the one or more SSB configurations associated with the first SCell by the first parameter, the network device 102 can send the SSB using the activated first SSB configuration, for example, the network device 102 can send the SSB using the activated first SSB configuration on the first SCell, and correspondingly, the terminal can receive the SSB on the first SCell according to the activated first SSB configuration, i.e., the terminal 101 can receive the SSB sent by the network device on the first SCell using the activated first SSB configuration.

[0155] The method related to the embodiments of the present disclosure can include at least one of steps S3101-S3103. For example, step S3101 can be implemented as an independent embodiment, step S3101+step S3102 can be implemented as an independent embodiment, step S3101+step S3103 can be implemented as an independent embodiment, step S3102 can be implemented as an independent embodiment, step S3103 can be implemented as an independent embodiment, but not limited thereto.
[0156] In some embodiments, steps S3102 and S3103 are optional, and one or more of these steps can be omitted or replaced in different embodiments.
[0157] In some embodiments, step S3103 is optional, and one or more of these steps can be omitted or replaced in different embodiments.
[0158] In some embodiments, step S3102 is optional, and one or more of these steps can be omitted or replaced in different embodiments.
[0159] In some embodiments, other optional implementations described before or after the corresponding description of FIG. 3A can be referred to.
[0160] FIG. 3B is an interaction diagram of a communication method, according to embodiments of the present disclosure. As shown in FIG. 3B, embodiments of the present disclosure relate to a communication method applicable to the communication system 100, and the method includes but is not limited to the following steps.
[0161] At step S3201, the first information is transmitted.
[0162] In some embodiments, the related description of the first information can be referred to the optional implementation of step S3101 of FIG. 3A and other associated parts of the embodiments related to FIG. 3A, which will not be repeated here.
[0163] In some embodiments, the first information in step S3201 is different from the first information in FIG. 3A as follows: the first information can include an SSB configuration, the SSB configuration can be at least one SSB configuration of one or more SSB configurations associated with the first SCell, and the SSB configuration can include a first SSB configuration. In some embodiments, the network device can indicate the activation state of the SSB configuration by whether the first parameter is configured in the SSB configuration, and the activation state includes deactivation or activation.
[0164] In some embodiments, the first information can include a first SSB configuration, the first SSB configuration can be an SSB configuration of one or more SSB configurations associated with the first SCell, for example, the first SSB configuration can be one SSB configuration of the one or more SSB configurations associated with the first SCell, and the first SCell can be a cell supporting on-demand request SSB. In some embodiments, the network device can indicate the activation state of the first SSB configuration by whether the first parameter is configured in the first SSB configuration.
[0165] In some embodiments, the first information described above can include but is not limited to RRC signaling, for example, the first information can be RRC signaling, which can include but is not limited to a first SSB configuration, the first SSB configuration can be one of one or more SSB configurations associated with the first SCell, and a first parameter can also be defined in the first SSB configuration, the first parameter associated with the first SSB configuration can indicate the activation state (such as activation or deactivation) of SSB transmission of the first SCell, and can also indicate that the activation state of the first SSB configuration is activated. For example, the first parameter associated with the first SSB configuration can indicate the activation state (such as activation or deactivation) of SSB transmission of the first SCell, and can also indicate that the activation state of the first SSB configuration is deactivated. For example, the network device can indicate whether the first SSB configuration is activated by whether the first parameter is configured in the first SSB configuration. That is, the difference between the embodiment in FIG. 3B and the embodiment in FIG. 3A is that the first parameter can or can not be included in the first SSB configuration sent by the network device in FIG. 3B, that is, the network device indicates the activation state of the first SSB configuration by whether the first parameter is configured in the first SSB configuration, so that the terminal receiving the first SSB configuration can determine the activation state of the first SSB configuration as activated or deactivated by whether the first parameter is configured in the first SSB configuration.
[0166] In some embodiments, the network device 102 can activate or deactivate the first SSB configuration by a first parameter associated with the first SSB configuration. In some embodiments, the network device 102 can indicate the activation state of the first SSB configuration by whether the first parameter is configured in the first SSB configuration. For example, the first parameter can be named as SSBstatus (SSB status), or other names. In a possible implementation, the first parameter can take a third value, for example, the third value can be “activated” or “enabled” or other values, which are not limited specifically. If the network device 102 configures the first parameter in the first SSB configuration, it indicates that the activation state of the first SSB configuration is activated, that is, the first parameter corresponding to the first SSB configuration indicates activation. If the network device 102 does not configure the first parameter in the first SSB configuration, it indicates that the activation state of the first SSB configuration is deactivated, that is, the first parameter corresponding to the first SSB configuration indicates deactivation. In another possible implementation, the first parameter can take a fourth value, for example, the fourth value can be “deactivated” or “disabled” or other values, which are not limited specifically. If the network device 102 configures the first parameter in the first SSB configuration, it indicates that the activation state of the first SSB configuration is deactivated, that is, the first parameter corresponding to the first SSB configuration indicates deactivation. If the network device 102 does not configure the first parameter in the first SSB configuration, it indicates that the activation state of the first SSB configuration is activated, that is, the first parameter corresponding to the first SSB configuration indicates activation.
[0167] In some embodiments, the network device 102 can activate or deactivate the SSB transmission of the first SCell by a first parameter associated with the SSB configuration, for example, if the first parameter corresponding to at least one SSB configuration of the one or more SSB configurations associated with the first SCell indicates activation, it can indicate that the first SCell activates the SSB transmission and transmits SSBs using the SSB configuration associated with the first parameter, that is, if the first parameter corresponding to at least one SSB configuration of the one or more SSB configurations associated with the first SCell indicates activation, it can indicate that the activation state of the SSB transmission of the first SCell is activated and the activation state of the SSB configuration associated with the first parameter is activated. For another example, if the first parameter corresponding to each SSB configuration of the one or more SSB configurations associated with the first SCell indicates deactivation, it indicates that the first SCell deactivates the SSB transmission, that is, it can indicate that the activation state of the SSB transmission of the first SCell is deactivated.
[0168] For example, assuming that the network device 102 configures the first parameter in the SSB configuration, it means to activate the SSB configuration, and the network device 102 configures the first parameter (such as the value of activated) in the SSB configuration 0, and does not configure the first parameter in the SSB configuration 1, the SSB configuration 2, and the SSB configuration 3, which means that the SSB transmission of the first SCell is activated, and the SSB configuration 0 is activated, and the SSB configuration 1, the SSB configuration 2, and the SSB configuration 3 are deactivated.
[0169] For example, assuming that the network device 102 configures the first parameter in the SSB configuration, it means to activate the SSB configuration, and the network device 102 configures the first parameter (such as the value of activated) in the SSB configuration 0, and does not configure the first parameter in the SSB configuration 1, the SSB configuration 2, and the SSB configuration 3, which means that the SSB transmission of the first SCell is activated, and the SSB configuration 0 is activated, and the SSB configuration 1, the SSB configuration 2, and the SSB configuration 3 are deactivated.
[0170] Optionally, in some embodiments, as shown in FIG. 3B, the method can further include step S3202. In step S3202, according to whether the first parameter is included in the first SSB configuration, the activation state of the first SSB configuration associated with the first parameter is determined as activated or deactivated.
[0171] In some embodiments, the terminal 101 receives the first information sent by the network device 102, which can include the first SSB configuration described above, and the terminal 101 can determine the activation state of the first SSB configuration according to whether the first parameter is included in the first SSB configuration. For example, if the value of the first parameter can be “activated”, the configuration of the first parameter in the first SSB configuration indicates that the activation state of the first SSB configuration is activated, and the non-configuration of the first parameter in the first SSB configuration indicates that the first SSB configuration is deactivated. For example, the terminal 101 receives the first information sent by the network device 102, and determines that the first parameter is configured in the first SSB configuration in the first information, and then the terminal 101 can determine that the activation state of the first SSB configuration is activated. If the terminal 101 determines that the first parameter is not configured in the first SSB configuration in the received first information, the terminal 101 can determine that the activation state of the first SSB configuration is deactivated. For another example, if the value of the first parameter can be “deactivated”, the configuration of the first parameter in the first SSB configuration indicates that the first SSB configuration is deactivated, and the non-configuration of the first parameter in the first SSB configuration indicates that the first SSB configuration is activated. For example, the terminal 101 receives the first information sent by the network device 102, and determines that the first parameter is configured in the first SSB configuration in the first information, and then the terminal 101 can determine that the activation state of the first SSB configuration is deactivated. If the terminal 101 determines that the first parameter is not configured in the first SSB configuration in the received first information, the terminal 101 can determine that the activation state of the first SSB configuration is activated.
[0172] Optionally, in some embodiments, the terminal 101 can determine the activation state of the SSB transmission of the first SCell according to the first parameter associated with the SSB configuration. For example, if the first parameter corresponding to at least one of the one or more SSB configurations associated with the first SCell indicates activation, the terminal 101 can determine that the activation state of the SSB transmission of the first SCell is activated and the activation state of the SSB configuration associated with the first parameter is activated. For example, if the first parameter corresponding to each of the one or more SSB configurations associated with the first SCell indicates deactivation, the terminal 101 can determine that the activation state of the SSB transmission of the first SCell is deactivated.
[0173] It is worth noting that in some embodiments, the network device 102 activates the SSB transmission of the first SCell by the first SSB configuration associated with the first parameter, and activates at least one first SSB configuration in the plurality of SSB configurations associated with the first SCell, and the network device 102 can send the SSB using the activated first SSB configuration, for example, the network device 102 can send the SSB using the activated first SSB configuration on the first SCell, and correspondingly, the terminal can receive the SSB on the first SCell according to the activated first SSB configuration, that is, the terminal 101 can receive the SSB sent by the network device using the activated first SSB configuration on the first SCell.
[0174] The method related to the embodiments of the present disclosure can include at least one of steps S3201-S3202. For example, step S3201 can be implemented as an independent embodiment, steps S3201+S3202 can be implemented as an independent embodiment, and step S3202 can be implemented as an independent embodiment, but is not limited thereto.
[0175] In some embodiments, step S3202 is optional, and one or more of the steps can be omitted or replaced in different embodiments.
[0176] In some embodiments, step S3201 is optional, and one or more of the steps can be omitted or replaced in different embodiments.
[0177] In some embodiments, other optional implementations described before or after the corresponding description of FIG. 3B can be referred to.
[0178] FIG. 3C is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 3C, the embodiments of the present disclosure relate to a communication method applicable to a communication system 100, and the above method includes but is not limited to the following steps.
[0179] Step S3301, sending first information.
[0180] In some embodiments, the related description of the first information can be referred to the optional implementation of step S3101 of FIG. 3A and other associated parts in the embodiments related to FIG. 3A, which will not be repeated here.
[0181] In some embodiments, the first information in step S3301 is different from the first information in FIG. 3A and FIG. 3B in that: the first information can comprise a cell configuration of the SCell. Illustratively, the cell configuration can be a ServingCellConfigCommon, a ServingCellConfig, or a SCellConfig. In the cell configuration, a second parameter associated with the SCell can be defined, which can indicate an activated SSB configuration, which can be an SSB configuration of one or more SSB configurations associated with the SCell.
[0182] In some embodiments, the first information can comprise a cell configuration of the first SCell. Illustratively, the cell configuration can be a ServingCellConfigCommon, a ServingCellConfig, or a SCellConfig. In the cell configuration, a second parameter associated with the first SCell can be defined, which can indicate an activated SSB configuration, which can be an SSB configuration of one or more SSB configurations associated with the first SCell, the first SCell being a cell supporting on-demand SSB. In some embodiments, the second parameter can be used to determine the activated SSB configuration of the first SCell; wherein if the activated SSB configuration of the first SCell comprises the first SSB configuration, the activation state of the first SSB configuration is activated; or if the activated SSB configuration of the first SCell does not comprise the first SSB configuration, the activation state of the first SSB configuration is deactivated.
[0183] In some embodiments, the first information described above can include but is not limited to RRC signaling, for example, the first information can be RRC signaling, which can include but is not limited to a second parameter, which can indicate an activated SSB configuration, for example, can indicate an identity of the activated SSB configuration, which can be an SSB configuration among one or more SSB configurations associated with the first SCell, such as the first SSB configuration can be an SSB configuration associated with the first SCell, or the first SSB configuration can be the activated SSB configuration (i.e., the first SCell activates the first SSB configuration), and the first SCell is a cell that requests an SSB on demand. For example, the second parameter can be configured in a cell granularity (i.e., the second parameter can be configured in a cell unit), for example, the second parameter can be configured in a cell configuration, for example, the cell configuration can be ServingCellConfigCommon, or ServingCellConfig, or SCellConfig, i.e., the second parameter can be configured in ServingCellConfigCommon, the second parameter can be configured in ServingCellConfig, and the second parameter can be configured in SCellConfig.
[0184] In some embodiments, in the case that the first SCell is associated with multiple SSB configurations, each SSB configuration is associated with (or corresponds to) a configuration identity (or identity), the multiple SSB configurations include the first SSB configuration described above, for example, the identity can be index, or Identifier, or ConfigurationID, which can be carried in the SSB configuration when the network device configures the SSB configuration. For example, the initial state of the SSB configuration can be deactivated, for example, the default state of the SSB configuration when the network device configures the SSB configuration to the terminal can be deactivated (i.e., the default state of the SSB configuration when the SSB configuration is configured can be deactivated), and the network device 102 can indicate the activated SSB configuration through the second parameter, for example, the identity of the activated SSB configuration.
[0185] In some embodiments, the value range of the second parameter can be determined by the number of SSB configurations associated with the first SCell, for example, the more the number of SSB configurations associated with the first SCell, the more the value range of the second parameter. For example, if the number of SSB configurations associated with the first SCell is 4, that is, 4 SSB configurations are supported, the value range of the second parameter can be (0…3), for example, if the value of the second parameter is 0, it can indicate that the SSB configuration associated with index 0 is activated, if the value of the second parameter is 1, it can indicate that the SSB configuration associated with index 1 is activated, if the value of the second parameter is 2, it can indicate that the SSB configuration associated with index 2 is activated, and if the value of the second parameter is 3, it can indicate that the SSB configuration associated with index 3 is activated. For another example, if the number of SSB configurations associated with the first SCell is 8, that is, 8 SSB configurations are supported, the value range of the second parameter can be (0…7), for example, if the value of the second parameter is 0, it can indicate that the SSB configuration associated with index 0 is activated, and so on. It can be understood that the above examples of the value range of the second parameter are only one possible implementation for the convenience of those skilled in the art, that is, the value range of the second parameter can also be implemented in other ways, and the present disclosure does not limit this, and will not be repeated here.
[0186] It is worth noting that in some embodiments, in the case of associating one or more SSB configurations with the first SCell, each SSB configuration is associated with (or corresponds to) a configuration identifier (or identifier), and the default state of the SSB configuration when the network device configures the SSB configuration to the terminal can be deactivated (that is, the default state of the SSB configuration when it is configured can be deactivated), then the network device can indicate the activated SSB configuration through the second parameter, for example, the identifier of the activated SSB configuration can be indicated through the second parameter, and correspondingly, the terminal 101 can determine the activation state of the SSB configuration associated with the identifier indicated by the second parameter to be activated.
[0187] In some embodiments, the network device indicates, by the second parameter, that the number of activated SSB configurations can be one, for example, in the case that the first SCell is associated with multiple SSB configurations, each SSB configuration is associated with (or corresponds to) one configuration identifier (or index), and each value of the second parameter indicates that the SSB configuration associated with the corresponding index is activated. For example, if the number of SSB configurations associated with the first SCell is four, i.e., four SSB configurations are supported, the value range of the second parameter can be (0…3), for example, if the value of the second parameter is 0, it indicates that the SSB configuration associated with index 0 is activated, if the value of the second parameter is 1, it indicates that the SSB configuration associated with index 1 is activated, if the value of the second parameter is 2, it indicates that the SSB configuration associated with index 2 is activated, and if the value of the second parameter is 3, it indicates that the SSB configuration associated with index 3 is activated.
[0188] In some embodiments, the network device indicates, by the second parameter, that the number of activated SSB configurations can be multiple, for example, in the case that the first SCell is associated with multiple SSB configurations, the multiple SSB configurations are divided into one or more groups, each group corresponds to one group identifier, and the network device carries the group identifier of the group to which the SSB configuration belongs in the SSB configuration when configuring the SSB configuration. For example, the initial state of the SSB configuration can be deactivated. The activated SSB configuration can be indicated by the second parameter, for example, the second parameter indicates the group identifier of the activated SSB configuration group, and each value of the second parameter indicates that the SSB configuration associated with the corresponding group identifier is activated. For example, if the number of SSB configurations associated with the first SCell is four, i.e., four SSB configurations are supported, and the four SSB configurations are divided into two groups, each group includes two SSB configurations, for example, one group includes SSB configuration 0 and SSB configuration 1, and the other group includes SSB configuration 2 and SSB configuration 3, the value range of the second parameter can be (0…1), for example, if the value of the second parameter is 0, it indicates the activation of SSB configuration 0 and SSB configuration 1 associated with group identifier 0 (i.e., activating SSB configuration 0 and SSB configuration 1); if the value of the second parameter is 1, it indicates the activation of SSB configuration 2 and SSB configuration 3 associated with group identifier 1 (i.e., activating SSB configuration 2 and SSB configuration 3).
[0189] Optionally, in some embodiments, as shown in FIG. 3C, the method can further include step S3302.
[0190] Step S3302: determining, according to the second parameter, the SSB configuration activated by the first SCell.
[0191] In some embodiments, it can be determined that the first SCell corresponds to one or more activated SSB configurations among the one or more SSB configurations associated with the second parameter, the first SSB configuration can be the activated SSB configuration, or the first SSB configuration can also not be the activated SSB configuration. For example, if the first SCell activated SSB configuration includes the first SSB configuration, the activation state of the first SSB configuration is activated; or if the first SCell activated SSB configuration does not include the first SSB configuration, the activation state of the first SSB configuration is deactivated.
[0192] In some embodiments, the second parameter is associated with the first SCell, the first SCell is associated with one or more SSB configurations, the second parameter can indicate an activated SSB configuration, for example, can indicate an identity of the activated SSB configuration; the activated SSB configuration indicated by the second parameter can be an SSB configuration among the one or more SSB configurations associated with the first SCell; the activated SSB configuration indicated by the second parameter can include the first SSB configuration, or can also not include the first SSB configuration. If the activated SSB configuration indicated by the second parameter includes the first SSB configuration, the activation state of the first SSB configuration is activated; or if the activated SSB configuration indicated by the second parameter does not include the first SSB configuration, the activation state of the first SSB configuration is deactivated.
[0193] In some embodiments, the second parameter is associated with the first SCell, the second parameter indicates an activated first SSB configuration, the first SSB configuration is an SSB configuration among the one or more SSB configurations associated with the first SCell; it can be determined according to the second parameter that the activation state of the first SSB configuration is activated. For example, according to the identity indicated by the second parameter, it can be determined that the activation state of the first SSB configuration associated with the identity is activated. The first SCell can be a cell supporting on-demand request SSB.
[0194] In some embodiments, the terminal 101 receives the first information sent by the network device 102, which can include the second parameter described above, and the terminal 101 can determine, according to the identity indicated by the second parameter, that the activation state of the first SSB configuration associated with the identity is activated, and the first SSB configuration associated with the identity can be one of the one or more SSB configurations corresponding to the first SCell associated with the second parameter. For example, in the case where the first SCell is associated with one or more SSB configurations, the first SCell is associated with a second parameter, and each of the one or more SSB configurations associated with the first SCell is associated with (or corresponds to) a configuration identity (or identity), such as an index or an identifier or a configuration ID, which can be carried in the SSB configuration when the network device configures the SSB configuration. For example, the initial state of the SSB configuration can be deactivated, for example, the default state of the SSB configuration when the network device configures the SSB configuration to the terminal can be deactivated (i.e., the default state of the SSB configuration when the SSB configuration is configured can be deactivated), and the network device 102 can indicate the activated SSB configuration among the one or more SSB configurations associated with the first SCell through the second parameter associated with the first SCell, for example, by indicating the identity of the activated SSB configuration. The terminal 101 receives the second parameter sent by the network device 102 and determines to activate the SSB configuration corresponding to the identity indicated by the second parameter.
[0195] For example, in the case where the number of SSB configurations associated with the first SCell is four, the first SCell is associated with a second parameter, and the value range of the second parameter can be (0…3), if the terminal 101 receives the second parameter with a value of 0, the terminal 101 can determine that the SSB configuration associated with index 0 is activated; if the terminal 101 receives the second parameter with a value of 1, the terminal 101 can determine that the SSB configuration associated with index 1 is activated; if the terminal 101 receives the second parameter with a value of 2, the terminal 101 can determine that the SSB configuration associated with index 2 is activated; and if the terminal 101 receives the second parameter with a value of 3, the terminal 101 can determine that the SSB configuration associated with index 3 is activated.
[0196] In some embodiments, the network device indicates, by the second parameter, that the number of activated SSB configurations can be multiple, for example, in the case that the first SCell is associated with multiple SSB configurations, the first SCell is associated with one second parameter, the multiple SSB configurations are divided into one or more groups, each group corresponds to one group identifier, and when the network device configures an SSB configuration, the group identifier of the group to which the SSB configuration belongs is carried in the SSB configuration. For example, the initial state of the SSB configuration can be deactivated. The activated SSB configuration can be indicated by the second parameter, for example, the second parameter indicates the group identifier of the activated SSB configuration group, and each value of the second parameter indicates that the SSB configuration associated with the corresponding group identifier is activated. For example, the number of SSB configurations associated with the first SCell is 4, the 4 SSB configurations are divided into 2 groups, each group includes 2 SSB configurations, for example, one group includes SSB configuration 0 and SSB configuration 1, and the other group includes SSB configuration 2 and SSB configuration 3, the first SCell is associated with one second parameter, and the value range of the second parameter can be (0…1). For example, if the value of the second parameter received by the terminal 101 is 0, the terminal 101 can determine that the SSB configurations 0 and 1 associated with the group identifier 0 are activated (i.e., activate SSB configuration 0 and SSB configuration 1); if the value of the second parameter received by the terminal 101 is 1, the terminal 101 can determine that the SSB configurations 2 and 3 associated with the group identifier 1 are activated (i.e., activate SSB configuration 2 and SSB configuration 3).
[0197] Optionally, in some embodiments, as shown in FIG. 3C, the method can further include step S3303.
[0198] Step S3303, determining the activation state of the SSB transmission of the first SCell according to whether the second parameter is included in the cell configuration associated with the first SCell.
[0199] In some embodiments, the first information can include a cell configuration, the cell configuration defines the second parameter, and the network device can indicate the activation state of the SSB transmission of the cell associated with the second parameter by whether the second parameter is configured in the cell configuration; wherein the second parameter can indicate the activated SSB configuration.
[0200] In some embodiments, the first information can comprise a cell configuration of the first SCell, the cell configuration defining a second parameter, the second parameter being associated with the first SCell, and the network device can activate or deactivate SSB transmission of the first SCell by the second parameter. For example, the network device can indicate the activation state of SSB transmission of the first SCell by whether the second parameter is configured in the cell configuration of the first SCell. For example, the second parameter can be configured in the cell configuration associated with the first SCell, which can be ServingCellConfigCommon, ServingCellConfig, or SCellConfig. For example, if the second parameter is configured, it indicates that the first SCell activates SSB transmission and transmits SSBs using the SSB configuration indicated by the second parameter (i.e., indicates that the SSB transmission of the first SCell is activated and the SSB configuration indicated by the second parameter is activated). If the second parameter is not configured, it indicates that none of the SSB configurations associated with the first SCell is activated, i.e., the SSB transmission of the first SCell is deactivated, or the SSB transmission of the first SCell can also be deactivated. Accordingly, the terminal 101 receives the first information sent by the network device 102, the first information comprising RRC signaling, which can comprise a cell configuration associated with the first SCell, and the terminal 101 can determine the activation state of the SSB transmission of the first SCell according to whether the second parameter is included in the cell configuration associated with the first SCell. For example, if the second parameter is included in the cell configuration associated with the first SCell, the terminal 101 can determine that the first SCell activates SSB transmission, i.e., the activation state of the SSB transmission of the first SCell is activated. If the second parameter is not included in the cell configuration associated with the first SCell, the terminal 101 can determine that the first SCell deactivates SSB transmission, i.e., the activation state of the SSB transmission of the first SCell is deactivated.
[0201] It should be noted that in some embodiments, the second parameter can be configured in a BWP (Bandwidth Part) granularity, that is, the second parameter can be configured in a BWP unit, that is, different BWP configurations can be associated with different second parameters. For example, if BWP switching occurs, the terminal 101 can use the second parameter associated with the switched BWP, or the terminal 101 can use the second parameter associated with the default BWP. For example, the network device 102 sends the first information to the terminal 101, the first information can be RRC signaling, the RRC signaling can include the second parameter, the second parameter is associated with the first BWP configuration, the first BWP configuration is the BWP configuration associated with the first SCell (that is, the first BWP configuration is the partial bandwidth configured for the first SCell), and the second parameter can indicate the activated first SSB configuration, for example, can indicate the identifier of the activated first SSB configuration. The terminal 101 receives the first information sent by the network device 102, the second parameter in the first information is associated with the first BWP configuration, and the terminal 101 can determine that the identifier indicated by the second parameter associated with the first BWP configuration indicates that the first SSB configuration associated with the identifier is activated, and the first SSB configuration associated with the identifier is one or more SSB configurations associated with the first SCell.
[0202] For example, the terminal 101 determines to switch from the first BWP configuration to the second BWP configuration, and the second BWP configuration is one of the multiple BWP configurations associated with the first SCell, and the terminal 101 can determine that the identifier indicated by the second parameter associated with the second BWP configuration indicates that the first SSB configuration associated with the identifier is activated, and the first SSB configuration associated with the identifier is at least one of the multiple SSB configurations associated with the first SCell. Alternatively, the terminal 101 can determine that the identifier indicated by the second parameter associated with the default BWP configuration indicates that the first SSB configuration associated with the identifier is activated, and the first SSB configuration associated with the identifier is one or more SSB configurations associated with the first SCell, the default BWP configuration can be one of the multiple BWP configurations associated with the first SCell, and the default BWP configuration can be agreed by the protocol, or can be configured or preconfigured by the network device.
[0203] It should be noted that in some embodiments, the above steps S3302 and S3303 can be a parallel scheme, for example, steps S3301+step S3302 can be implemented as an independent embodiment, and steps S3301+step S3303 can be implemented as an independent embodiment.
[0204] It is worth noting that in some embodiments, the network device 102 indicates the activated first SSB configuration through the second parameter, and then the network device can send the SSB using the activated first SSB configuration. For example, the network device 102 can send the SSB using the activated first SSB configuration on the first SCell, and accordingly, the terminal can receive the SSB on the first SCell according to the activated first SSB configuration, i.e., the terminal 101 can receive the SSB sent by the network device using the activated first SSB configuration on the first SCell.
[0205] The method related to the embodiments of the present disclosure can include at least one of steps S3301-S3303. For example, step S3301 can be implemented as an independent embodiment, steps S3301+S3302 can be implemented as an independent embodiment, steps S3301+S3303 can be implemented as an independent embodiment, step S3302 can be implemented as an independent embodiment, step S3303 can be implemented as an independent embodiment, but not limited thereto.

[0210] FIG. 3D is an interaction schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 3D, the embodiments of the present disclosure relate to a communication method applicable to a communication system 100, and the above method includes but is not limited to the following steps.
[0211] Step S3401, sending first information.
[0212] In some embodiments, the related description of the first information can be referred to the optional implementation of step S3101 of FIG. 3A and other associated parts in the embodiments related to FIG. 3A, which will not be described here.
[0213] In some embodiments, the first information in step S3401 is different from the first information in FIG. 3A, FIG. 3B, and FIG. 3C in that: the first information can include a MAC CE, for example, the first information can be a MAC CE. The MAC CE can indicate an SCell of which SSB transmission is activated or deactivated, and can also indicate the activation state of the SSB configuration associated with the SCell. For example, the MAC CE can be associated with one LCID (logical channel identify) or eLCID (enhanced logical channel identify). For example, the first information is identified as an LCID, the identification of the first information can be one LCID selected from an LCID reserved pool, and the LCID reserved pool includes at least one LCID. For example, the first information is identified as an eLCID; the identification of the first information can be one eLCID selected from an eLCID reserved pool, and the eLCID reserved pool includes at least one eLCID.
[0214] In some embodiments, the first information can include a first bitmap, and the first bitmap can include at least one first indication bit, each first indication bit corresponding to one secondary cell, and each first indication bit can be used to indicate SSB transmission activation or deactivation on the corresponding secondary cell. The at least one first indication bit indicates the secondary cell, which includes a first cell and a second cell, the first cell can be a cell requesting SSB on demand, and the first cell includes the first SCell described above, and the second cell is a normal cell. For example, the first indication bit described above can be set to a fifth value, which can be used to indicate SSB transmission activation on the corresponding secondary cell (i.e., to indicate activating SSB transmission on the secondary cell corresponding to the first indication bit); the first indication bit described above can be set to a sixth value, which can be used to indicate SSB transmission deactivation on the corresponding secondary cell (i.e., to indicate deactivating SSB transmission on the secondary cell corresponding to the first indication bit). For example, the fifth value can be 1, and the sixth value can be 0; or the fifth value can be 0, and the sixth value can be 1; or the fifth value and the sixth value use other value modes, which are not limited in the present disclosure and will not be described herein. For example, the terminal can ignore the first indication bit corresponding to the normal cell or the first indication bit corresponding to the normal cell can be a special value.
[0215] For example, taking the bitmap size of the first bitmap of the first bitmap as an example, the at least one first indication bit is associated with at least one secondary cell including SCellindex 1, 2, 3, 4, 5, 6, 7 SCell, wherein SCellindex 1, 3, 5 SCell is a cell that requests SSB on demand, SCellindex 1 SCell is the first SCell, i.e. a cell supporting on-demand SSB function (i.e. SCellindex 1, 3, 5 SCell is an on-demand SCell), SCellindex 2, 4, 6, 7 SCell is a normal cell (i.e. the second cell), SCellindex 1, 2, 3, 4, 5, 6, 7 SCell is the SCell configured for terminal 101, then the first bitmap can include 1 reserved bit (R bit) and 7 first indication bits (for example, denoted as Ci, or other names can be named). According to the secondary cell index (SCellindex) from small to large, each of the 7 first indication bits corresponds to one of the SCellindex 1, 2, 3, 4, 5, 6, 7 SCell, for example, C1 corresponds to the SCellindex 1 secondary cell, C2 corresponds to the SCellindex 2 secondary cell, and so on. Each first indication bit is used to indicate the activation or deactivation of SSB transmission on the corresponding secondary cell. Wherein, for i respectively 1, 3, 5, the first indication bit Ci associated with SCellindex i SCell is the fifth value (such as 1), indicating activating SSB transmission of SCellindex i SCell; the first indication bit Ci associated with SCellindex i SCell is the sixth value (such as 0), indicating deactivating SSB transmission of SCellindex i SCell. In some embodiments, the size of the first bitmap can be related to the number of secondary cells (including the first cell and the second cell), and the number of secondary cells is the number of first indication bits. That is, terminal 101 can determine the size of the first bitmap based on the number of secondary cells. Wherein, the number of secondary cells can be determined based on the cell configuration configured by the network device.
[0216] In some embodiments, the first information can define the first bitmap and further define first indication information. In other words, the first information can include the first bitmap and further include 0 or at least one first indication information. The number of the first indication information is the same as the number of the activated SSB transmission secondary cells. Each activated SSB transmission secondary cell is associated with one first indication information. The first indication information is ordered according to the index of the activated SSB transmission secondary cells (e.g., ordered from small to large or from large to small). The first indication information indicates the activated SSB configuration. For example, the first indication information indicates the identity of the activated SSB configuration. The SSB configuration indicated by the first indication information can be one or more SSB configurations associated with the activated SSB transmission secondary cell. Optionally, if the value of the first indication bit corresponding to the first SCell in the first bitmap is the fifth value (e.g., 1), it means that the activation state of the SSB transmission of the first SCell is activated. The activated SSB configuration associated with the first SCell can be indicated by the first indication information. If the activated SSB configuration includes the first SSB configuration, it means that the activation state of the first SSB configuration is activated. If the activated SSB configuration does not include the first SSB configuration, it means that the activation state of the first SSB configuration is deactivated.
[0217] For example, as shown in FIG. 4A, taking the size of the first bitmap as 1 byte as an example, the first bitmap includes 1 reserved bit (i.e., R) and 7 first indication bits (e.g., denoted as Ci, i can be 1, 2, 3, 4, 5, 6, 7). Each first indication bit corresponds to one SCell. For example, for the on-demand SSB requesting cell, Ci set to 1 means activating the SSB of the SCell with index i, and Ci set to 0 means deactivating the SSB of the SCell with index i. For the normal cell (the cell that normally transmits SSB), the terminal can ignore the Ci corresponding to the normal cell or the Ci corresponding to the normal cell can be a special value. The MAC CE can include 0 or more first indication information in addition to the bitmap. For example, each activated SSB transmission SCell is associated with one first indication information. The SCell that is deactivated SSB transmission is not associated with the first indication information. The 0 or more SSB first indication information is arranged in ascending order of the index of the activated SCell. The first indication information indicates the identity of the activated SSB configuration (e.g., denoted as SSB ID i For example, SSB ID i indicates that the activated SSB transmission SCell uses / activates the SSB IDi The number of the first indication information is the number of the SSB configurations associated with the SCell whose SSB transmission is activated, i.e., N in FIG. 4A.
[0218] For example, if the number of the SCells whose SSB transmission is activated is 0, e.g., none of the SCells with SCellindex 1, 2, 3, 4, 5, 6, 7 has its SSB transmission activated, the number of the first indication information is 0. For example, if the SCells with SCellindex 1 and SCellindex 3 have their SSB transmission activated, the number of the first indication information in the MAC CE is 2, and the SCell with SCellindex 1 and the SCell with SCellindex 3 are associated with the first indication information respectively, and the two first indication information are sorted according to the SCellindex, e.g., the two first indication information are sorted in ascending order or descending order according to the SCellindex, and each of the two first indication information can be used to indicate the identity of one or more SSB configurations associated with the corresponding SCell, and the identity of the SSB configuration used / activated by the SCell whose SSB transmission is activated. Each SSB configuration corresponds to a configuration identity (or identity), e.g., index / ID / ConfigurationID. For example, as shown in FIG. 4A, if the SCells with SCellindex 1 and SCellindex 3 have their SSB transmission activated, and the SCell with SCellindex 1 is the first SCell (i.e., the SCell whose SSB is requested on demand), and the SCell with SCellindex 1 is associated with SSB configuration 0 and SSB configuration 1, the number of the first indication information in the MAC CE is 1, and the first indication information is associated with the SCell with SCellindex 1, and the first indication information can be used to indicate the identity of the first SSB configuration of the two SSB configurations associated with the SCell with SCellindex 1, i.e., the MAC CE includes one first indication information, and the first indication information indicates SSB ID1, which represents the identity of the SSB configuration of the two SSB configurations associated with the SCell with SCellindex 1. For example, if the identity of the SSB configuration 0 associated with the SCell with SCellindex 1 is 0, and the identity of the SSB configuration 1 associated with the SCell with SCellindex 1 is 1, if the first indication information is 0, it means that the SSB configuration 0 with the identity of 0 is activated; if the first indication information is 1, it means that the SSB configuration 1 with the identity of 1 is activated.
[0219] Optionally, in some embodiments, after the terminal 101 receives the first information sent by the network device 102, the terminal 101 can determine the activation state of the SSB transmission of the first SCell according to the first bitmap of the first information; if the activation state of the SSB transmission of the first SCell is activated, the terminal 101 can further determine the activated SSB configuration used by the first SCell with activated SSB transmission according to the first indication information (i.e., the first indication information associated with the first SCell) of the first information, for example, the activated SSB configuration includes the first SSB configuration, and the activation state of the first SSB configuration is activated; or the activated SSB configuration does not include the first SSB configuration, and the activation state of the first SSB configuration is deactivated. Optionally, in some embodiments, the network device 102 activates the SSB transmission of the first SCell and activates the first SSB configuration in the one or more SSB configurations associated with the first SCell by using the MAC CE, and then the network device 102 can send the SSB by using the activated first SSB configuration, for example, the network device 102 can send the SSB by using the activated first SSB configuration on the first SCell, and correspondingly, the terminal can receive the SSB according to the activated first SSB configuration on the first SCell, i.e., the terminal 101 can receive the SSB sent by the network device on the first SCell by using the activated first SSB configuration.
[0220] In some embodiments, the first information described above can include a second bitmap, and the second bitmap includes at least one second indication bit, each second indication bit corresponds to a secondary cell, and each second indication bit is used to indicate the activation or deactivation of the SSB transmission on the corresponding secondary cell. The secondary cell indicated in the at least one second indication bit is the first cell, the first cell is the cell that requests the SSB on demand, and the first cell includes the first SCell. For example, the value of the second indication bit described above is the fifth value, which can be used to indicate the activation of the SSB transmission on the secondary cell corresponding to the second indication bit (i.e., to indicate the activation of the SSB transmission on the secondary cell corresponding to the second indication bit); the value of the second indication bit described above is the sixth value, which can be used to indicate the deactivation of the SSB transmission on the secondary cell corresponding to the second indication bit (i.e., to indicate the deactivation of the SSB transmission on the secondary cell corresponding to the second indication bit). For example, the fifth value can be 1, and the sixth value can be 0; or the fifth value can be 0, and the sixth value can be 1; or the fifth value and the sixth value use other value modes, which are not limited in the present disclosure and will not be described herein.
[0221] For example, assuming that SCells with SCellindex of 1, 2, 3, 4, 5, 6, 7 are SCells configured for the terminal 101, SCells with SCellindex of 1, 3, 5 are on-demand SSB cells, SCell with SCellindex of 1 is the first SCell, i.e., the cell supporting the on-demand SSB function (i.e., SCells with SCellindex of 1, 3, 5 are on-demand SCells), SCells with SCellindex of 2, 4, 6, 7 are normal cells (i.e., the second cells), and the size of the second bitmap in the MAC CE is 1 byte, for example, the at least one secondary cell associated with the at least one second indication bit includes SCells with SCellindex of 1, 3, 5, and the second bitmap can include 3 second indication bits (e.g., denoted as Ci, which can also be named by other names) that can have reserved bits. In order to achieve byte alignment, each second indication bit excluding the reserved bits corresponds to one secondary cell (on-demand SSB cell). In ascending order of secondary cell index (SCellindex), each second indication bit of the 3 second indication bits corresponds to one secondary cell among the SCells with SCellindex of 1, 3, 5, for example, C1 corresponds to the secondary cell with SCellindex of 1, C2 corresponds to the secondary cell with SCellindex of 3, and C3 corresponds to the secondary cell with SCellindex of 5. Each second indication bit is used to indicate the activation or deactivation of SSB transmission on the corresponding secondary cell. For i being 1, 3, 5 respectively, the second indication bit Ci associated with the SCell with SCellindex of i is the fifth value (e.g., 1), indicating the activation of SSB transmission of the SCell with SCellindex of i; the second indication bit Ci associated with the SCell with SCellindex of i is the sixth value (e.g., 0), indicating the deactivation of SSB transmission of the SCell with SCellindex of i. In some embodiments, the size of the second bitmap can be related to the number of secondary cells (including only the first cells, i.e., only the on-demand SSB cells), which is the number of first indication bits. That is, the terminal 101 can determine the size of the second bitmap based on the number of secondary cells. The number of secondary cells can be determined based on the cell configuration configured by the network device. The size of the second bitmap can be smaller than the number of secondary cells.
[0222] In some embodiments, the first information can further comprise one or more first indication information in addition to the second bitmap. The number of the first indication information is the same as the number of the activated SSB transmission secondary cells, each of the activated SSB transmission secondary cells is associated with one of the first indication information, and the first indication information is ordered according to the index of the activated SSB transmission secondary cells (e.g., ordered from small to large or from large to small). The first indication information indicates the identity of the activated SSB configuration, and the SSB configuration indicated by the first indication information can be one of the one or more SSB configurations associated with the activated SSB transmission secondary cell. For example, if the number of the activated SSB transmission secondary cells is 0, e.g., none of the SSB transmission of the SCell with SCellindex 1, 3, 5 (e.g., the SCell with SCellindex 1, 3, 5 is an on-demand SCell) is activated, the number of the first indication information is 0. For example, if the activated SSB transmission secondary cells are the SCell with SCellindex 1 and the SCell with SCellindex 3, the number of the first indication information in the first information is 2, the SCell with SCellindex 1 and the SCell with SCellindex 3 are respectively associated with one of the first indication information, and the two first indication information is ordered according to the SCellindex, e.g., ordered from small to large or from large to small. Each of the two first indication information can be used to indicate the identity of the SSB configuration of the one or more SSB configurations associated with the corresponding secondary cell, and the identity of the activated SSB configuration used by the activated SSB transmission secondary cell. Each SSB configuration corresponds to one configuration identity (or identity), e.g., index / ID / ConfigurationID. For example, if the activated SSB transmission secondary cell is the SCell with SCellindex 1, the SCell with SCellindex 1 is the first SCell (e.g., the on-demand SCell), and the SCell with SCellindex 1 is associated with SSB configuration 0 and SSB configuration 1, the number of the first indication information in the first information is 1, the first SCell is associated with the first indication information, and the first indication information can be used to indicate the identity of the first SSB configuration of the two SSB configurations associated with the first SCell.For example, the first SCell is associated with SSB configuration 0 with an identity of 0 and SSB configuration 1 with an identity of 1. If the first indication information is 0, it indicates that the SSB configuration 0 with the identity of 0 is activated. If the first indication information is 1, it indicates that the SSB configuration 1 with the identity of 1 is activated.
[0223] Optionally, in some embodiments, after the terminal 101 receives the first information sent by the network device 102, the terminal 101 can determine the activation state of the SSB transmission of the first SCell according to the second bitmap of the first information. If the activation state of the SSB transmission of the first SCell is activated, the terminal 101 can further determine the identity of the activated SSB configuration used by the first SCell with activated SSB transmission according to the first indication information (i.e., the first indication information associated with the first SCell) of the first information. For example, if the activated SSB configuration includes the first SSB configuration, the activation state of the first SSB configuration is activated. Or, if the activated SSB configuration does not include the first SSB configuration, the activation state of the first SSB configuration is deactivated. Optionally, in some embodiments, the network device 102 activates the SSB transmission of the first SCell and activates the first SSB configuration among one or more SSB configurations associated with the first SCell by using the MAC CE. Then, the network device 102 can send SSBs by using the activated first SSB configuration. For example, the network device 102 can send SSBs by using the activated first SSB configuration on the first SCell. Correspondingly, the terminal can receive SSBs on the first SCell according to the activated first SSB configuration, i.e., the terminal 101 can receive SSBs sent by the network device on the first SCell by using the activated first SSB configuration.
[0224] In some embodiments, the first information can include second indication information and a third bitmap, where the second indication information can indicate a first cell that activates SSB transmission, such as an identity of the first cell that activates SSB transmission (which can be represented by a Serving Cell ID), the first cell can be a cell that supports on-demand request of SSB, the first cell can include one or more SCells, and the first cell can include the first SCell; each indication bit in the third bitmap corresponds to an SSB configuration, and the indication bit in the third bitmap can be used to indicate activation or deactivation of the corresponding SSB configuration, and the SSB configuration indicated by the indication bit in the third bitmap can be one or more SSB configurations associated with the first cell. In some embodiments, the second indication information in the first information can indicate one or more cells that activate SSB transmission, and the first SCell can be one of the cells that activate SSB transmission, and the cell can be a cell that supports on-demand request of SSB. For example, the number of the second indication information in the first information can be the same as the number of the cells that activate SSB transmission.
[0225] In some embodiments, the first information can include second indication information and a third bitmap, where the second indication information can indicate an identity of the first SCell that activates SSB transmission (e.g., can be indicated by a Serving Cell ID); each indication bit in the third bitmap corresponds to one SSB configuration, and the indication bit in the third bitmap can be used to indicate activation or deactivation of the corresponding SSB configuration, and the SSB configuration indicated by the indication bit in the third bitmap can be one or more SSB configurations associated with the first SCell. For example, the identity of the first SCell that activates SSB transmission can be indicated by the second indication information, and the SSB configuration activated by the first SCell can be indicated by the third bitmap. Each SSB configuration can correspond to one configuration identity (or identity), e.g., index / ID / Configuration ID. According to the identity size of the SSB configuration (e.g., from large to small or from small to large), e.g., according to the identity of the SSB configuration from small to large, each indication bit in the third bitmap corresponds to one SSB configuration (there can be reserved bits, and each indication bit excluding the reserved bits corresponds to one SSB configuration for byte alignment), and for example, the fifth value (e.g., 1) of the indication bit in the third bitmap indicates activation of the SSB configuration corresponding to the indication bit, and the sixth value (e.g., 0) of the indication bit in the third bitmap indicates deactivation of the SSB configuration corresponding to the indication bit. For example, as shown in FIG. 4B, one or more second indication information can be included in the first information, each second indication information can indicate the identity of one cell that activates SSB transmission (indicated by Serving Cell ID), and the cell can be a cell that supports on-demand SSB request. One or more third bitmap can also be included in the first information, each third bitmap corresponds to one second indication information, and each indication bit in the third bitmap corresponds to one SSB configuration associated with the corresponding cell. i For example, as shown in FIG. 4B, one or more second indication information can be included in the first information, each second indication information can indicate the identity of one cell that activates SSB transmission (indicated by Serving Cell ID), and the cell can be a cell that supports on-demand SSB request. One or more third bitmap can also be included in the first information, each third bitmap corresponds to one second indication information, and each indication bit in the third bitmap corresponds to one SSB configuration associated with the corresponding cell. i For example, as shown in FIG. 4B, one or more second indication information can be included in the first information, each second indication information can indicate the identity of one cell that activates SSB transmission (indicated by Serving Cell ID), and the cell can be a cell that supports on-demand SSB request. One or more third bitmap can also be included in the first information, each third bitmap corresponds to one second indication information, and each indication bit in the third bitmap corresponds to one SSB configuration associated with the corresponding cell. i For example, as shown in FIG. 4B, one or more second indication information can be included in the first information, each second indication information can indicate the identity of one cell that activates SSB transmission (indicated by Serving Cell ID), and the cell can be a cell that supports on-demand SSB request. One or more third bitmap can also be included in the first information, each third bitmap corresponds to one second indication information, and each indication bit in the third bitmap corresponds to one SSB configuration associated with the corresponding cell. i For example, as shown in FIG. 4B, one or more second indication information can be included in the first information, each second indication information can indicate the identity of one cell that activates SSB transmission (indicated by Serving Cell ID), and the cell can be a cell that supports on-demand SSB request. One or more third bitmap can also be included in the first information, each third bitmap corresponds to one second indication information, and each indication bit in the third bitmap corresponds to one SSB configuration associated with the corresponding cell. i For example, as shown in FIG. 4B, one or more second indication information can be included in the first information, each second indication information can indicate the identity of one cell that activates SSB transmission (indicated by Serving Cell ID), and the cell can be a cell that supports on-demand SSB request. One or more third bitmap can also be included in the first information, each third bitmap corresponds to one second indication information, and each indication bit in the third bitmap corresponds to one SSB configuration associated with the corresponding cell. iCorresponding SSB configuration. In some embodiments, if more than 2 SSB configurations are supported, the third bitmap can be extended with the condition of byte alignment i Indication bit.
[0226] Optionally, in some embodiments, after receiving the first information sent by the network device 102, the terminal 101 can determine, according to the second indication information of the first information, that the activation state of the SSB transmission of the first cell is activated, and the first cell includes the first SCell; the terminal 101 can also determine, according to the third bitmap of the first information, the activated SSB configuration used by the first cell with activated SSB transmission, for example, can determine, according to the third bitmap associated with the second indication information in the first information, the activated SSB configuration used by the first SCell with activated SSB transmission. For example, if the activated SSB configuration includes the first SSB configuration, it can be considered that the activation state of the first SSB configuration is activated; if the activated SSB configuration does not include the first SSB configuration, it can be considered that the activation state of the first SSB configuration is deactivated. Optionally, the terminal can receive the SSB on the first SCell according to the activated first SSB configuration. For example, if the network device 102 activates the SSB transmission of the first SCell and activates the first SSB configuration associated with the first SCell through the MAC CE, the network device 102 can send the SSB using the activated first SSB configuration, for example, the network device 102 can send the SSB using the activated first SSB configuration on the first SCell, and correspondingly, the terminal 101 can receive the SSB sent by the network device using the activated first SSB configuration on the first SCell.
[0227] In some embodiments, the first information can include second indication information and third indication information, where the second indication information can indicate a first cell that activates SSB transmission, such as an identity of the first cell that activates SSB transmission (which can be represented by a Serving Cell ID), the first cell being a cell that supports on-demand requested SSB, the first cell can include one or more SCells, the first cell can include a first SCell; the third indication information can indicate an activated SSB configuration, such as an identity of the activated SSB configuration (which can be represented by an SSB config ID), the SSB configuration indicated by the third indication information can be an SSB configuration among one or more SSB configurations associated with the first cell. In some embodiments, the second indication information in the first information can indicate one or more cells that activate SSB transmission, the first SCell can be one of the cells that activate SSB transmission, the cell can be a cell that supports on-demand requested SSB. For example, the number of the second indication information in the first information can be the same as the number of the cells that activate SSB transmission. For example, the number of the third indication information can be the same as the number of the second indication information, one third indication information being associated with one second indication information.
[0228] In some embodiments, the first information can include second indication information and third indication information, where the second indication information can indicate an identity of a first SCell that activates SSB transmission (which can be represented by a Serving Cell ID); the third indication information can indicate an identity of an activated first SSB configuration (which can be represented by an SSB config ID), the first SSB configuration indicated by the third indication information can be an SSB configuration among one or more SSB configurations associated with the first SCell, the first SCell can be a cell that supports on-demand requested SSB. It is noted that in some embodiments, the bit length of the third indication information is related to the number of the SSB configurations associated with the first SCell.
[0229] For example, as shown in FIG. 4C, one or more second indication information can be included in the first information, each of the second indication information can indicate an identity (denoted as Serving Cell ID) of a cell which activates SSB transmission, the cell can be a cell which supports on-demand requesting SSB, and one or more third indication information can be included in the first information, each of the third indication information can correspond to one second indication information, and each of the third indication information indicates SSB configuration associated with the corresponding cell, for example, the third indication information indicates an identity (for example, denoted as SSB config ID) of activated SSB configuration. Taking the number of SSB configurations associated with the SCell as 4 (i.e., supporting 4 SSB configurations) as an example, the bit length of the third indication information can be 2 bits (i.e., 2 bits), for example, the value of the third indication information can be (00, 01, 10, 11), 00, 01, 10, 11 respectively corresponds to the identity of one SSB configuration (for example, 00 corresponds to the identity of SSB configuration 0, 01 corresponds to the identity of SSB configuration 1, 10 corresponds to the identity of SSB configuration 2, and 11 corresponds to the identity of SSB configuration 3), for example, the value of the third indication information is 00, which indicates that SSB configuration 0 is activated, the value of the third indication information is 01, which indicates that the first SSB configuration 1 is activated, and so on. Taking the number of SSB configurations associated with the first SCell as 8 (i.e., supporting 8 SSB configurations) as another example, the bit length of the third indication information can be 3 bits (i.e., 3 bits). It can be understood that the above-mentioned examples of the bit length of the third indication information are only examples given for the convenience of understanding by those skilled in the art, that is, the bit length of the third indication information can also be other values, which are not limited herein, and will not be described again.
[0230] Optionally, in some embodiments, after the terminal 101 receives the first information sent by the network device 102, the terminal 101 can determine, according to the second indication information of the first information, that the activation state of the SSB transmission of the first cell is activated, and the first cell includes the first SCell; and the terminal 101 can also determine, according to the third indication information of the first information, the activated SSB configuration used by the first cell with activated SSB transmission, for example, the activated SSB configuration used by the first SCell with activated SSB transmission can be determined according to the third indication information associated with the second indication information in the first information. For example, if the activated SSB configuration includes the first SSB configuration, it can be considered that the activation state of the first SSB configuration is activated; if the activated SSB configuration does not include the first SSB configuration, it can be considered that the activation state of the first SSB configuration is deactivated. Optionally, in some embodiments, after the network device 102 activates the SSB transmission of the first SCell and activates the first SSB configuration through the MAC CE, the network device 102 can use the activated first SSB configuration to send SSB, for example, the network device 102 can use the activated first SSB configuration to send SSB on the first SCell, and correspondingly, the terminal can receive SSB on the first SCell according to the activated first SSB configuration, that is, the terminal 101 can receive SSB sent by the network device on the first SCell using the activated first SSB configuration.
[0231] In some embodiments, other optional implementations described before or after the description of FIG. 3D can be referred to.
[0232] FIG. 3E is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 3E, the embodiment of the present disclosure relates to a communication method applicable to the communication system 100, and the above method includes but is not limited to the following steps.
[0233] Step S3501, sending first information.
[0234] In some embodiments, the related description of the first information can be referred to the optional implementation of step S3101 of FIG. 3A and other related parts in the embodiments related to FIG. 3A, which will not be described here.
[0235] In some embodiments, the first information in step S3501 is different from the first information in FIG. 3A, FIG. 3B, FIG. 3C, and FIG. 3D in that: the first information can include a PDCCH (Physical Downlink Control Channel) or DCI (Downlink Control Information) scrambled by a RNTI (Radio Network Temporary Identifier), for example, the first information can be a PDCCH or DCI scrambled by a RNTI. The PDCCH or DCI scrambled by the RNTI can be used to activate SSB transmission of the first SCell, and the first SCell can be a cell supporting on-demand SSB.
[0236] For example, the RNTI can be a newly defined RNTI, for example, the RNTI can be a group-based RNTI, for example, a group-common RNTI, that is, the RNTI can be a scrambling code that can be scrambled by a UE-group; for another example, the RNTI can be a specific UE-based RNTI, that is, the RNTI can be a scrambling code that can be scrambled by a specific UE.
[0237] In some embodiments, the first information can be a PDCCH or DCI scrambled by a RNTI, and the PDCCH or DCI scrambled by the RNTI can be sent on a first SCell, and the first SCell can be a cell supporting on-demand SSB. For example, the network device 102 sends a PDCCH or DCI scrambled by a RNTI on a first SCell, and correspondingly, the terminal 101 can receive the PDCCH or DCI scrambled by the RNTI sent by the network device 102 on the first SCell, and the PDCCH or DCI scrambled by the RNTI can be used to activate SSB transmission of the first SCell.
[0238] In some embodiments, in the case that the PDCCH or DCI scrambled by the RNTI is sent on the first SCell, the PDCCH or DCI scrambled by the RNTI can include a fourth bitmap, each indication bit in the fourth bitmap corresponds to one SSB configuration, and the indication bit in the fourth bitmap can be used to indicate activation or deactivation of the corresponding SSB configuration. The SSB configuration indicated by the indication bit in the fourth bitmap can be one or more SSB configurations associated with the first SCell, and the first SCell can be a cell supporting on-demand SSB. For example, the fifth value (such as 1) of the indication bit in the fourth bitmap indicates that the activation state of the SSB configuration corresponding to the indication bit is activated, and the sixth value (such as 0) of the indication bit in the fourth bitmap indicates that the activation state of the SSB configuration corresponding to the indication bit is deactivated.
[0239] In some embodiments, in the case that the RNTI scrambled PDCCH or DCI is transmitted on the first SCell, the RNTI scrambled PDCCH or DCI can comprise fourth indication information, which can indicate the activated first SSB configuration. For example, the fourth indication information can indicate an identity of the activated first SSB configuration. The first SSB configuration indicated by the fourth indication information is an SSB configuration among one or more SSB configurations associated with the first SCell. The first SCell can be a cell that requests SSB on demand. That is, in the case that the RNTI scrambled PDCCH or DCI is transmitted on the first SCell, the fourth indication information can be designed in the RNTI scrambled PDCCH or DCI, by which the identity of the activated first SSB configuration is directly indicated.
[0240] In some embodiments, the first information can be a RNTI scrambled PDCCH or DCI, which can be transmitted on a third cell. The third cell can be a primary cell or another secondary cell (such as any one SCell) associated with the first SCell. The first SCell can be a cell that requests SSB on demand. For example, the network device 102 transmits the RNTI scrambled PDCCH or DCI on the third cell. Accordingly, the terminal 101 can receive the RNTI scrambled PDCCH or DCI transmitted by the network device 102 on the third cell. The RNTI scrambled PDCCH or DCI can be used to activate SSB transmission of the first SCell. The third cell is a primary cell or another secondary cell associated with the first SCell. The first SCell is a cell that requests SSB on demand.
[0241] In some embodiments, in the case that the RNTI scrambled PDCCH or DCI is transmitted on the third cell, the RNTI scrambled PDCCH or DCI can comprise fifth indication information and a fourth bitmap. The fifth indication information can indicate a first cell that activates SSB transmission. The first cell can be a cell that supports SSB on demand. The first cell can comprise one or more SCells. The first cell can comprise the first SCell. Each indication bit in the fourth bitmap corresponds to an SSB configuration. The indication bit in the fourth bitmap can be used to indicate activation or deactivation of the corresponding SSB configuration. The SSB configuration indicated by the indication bit in the fourth bitmap is one or more SSB configurations associated with the first cell.
[0242] In some embodiments, in the case that the RNTI scrambled PDCCH or DCI can be transmitted on the third cell, the RNTI scrambled PDCCH or DCI can include fifth indication information and a fourth bitmap, wherein the fifth indication information can indicate the first SCell that activates the SSB transmission, and the first SCell can be a cell supporting on-demand request of SSB; each indication bit in the fourth bitmap corresponds to an SSB configuration, and the indication bit in the fourth bitmap can be used to indicate the activation or deactivation of the corresponding SSB configuration. The SSB configuration indicated by the indication bit in the fourth bitmap is one or more SSB configurations associated with the first SCell, and the SSB configuration indicated by the indication bit in the fourth bitmap includes the first SSB configuration. For example, in the case that the RNTI scrambled PDCCH or DCI can be transmitted on the third cell, an indication bit (i.e., the fifth indication information) needs to be designed in the RNTI scrambled PDCCH or DCI, and the first SCell that activates the SSB transmission is indicated by the fifth indication information. The fourth bitmap can also be included in the RNTI scrambled PDCCH or DCI, and the activation state of the corresponding SSB configuration is indicated by the indication bit in the fourth bitmap. For example, the fifth value (such as 1) of the indication bit in the fourth bitmap indicates that the activation state of the SSB configuration corresponding to the indication bit is activated, and the sixth value (such as 0) of the indication bit in the fourth bitmap indicates that the activation state of the SSB configuration corresponding to the indication bit is deactivated.
[0243] In some embodiments, in the case that the RNTI scrambled PDCCH or DCI can be transmitted on the third cell, the RNTI scrambled PDCCH or DCI can include fifth indication information and fourth indication information, wherein the fifth indication information can indicate the first cell that activates the SSB transmission, and the first cell can be a cell supporting on-demand request of SSB, the first cell can include one or more SCells, and the first cell includes the first SCell; and the fourth indication information can indicate the activated SSB configuration, and the SSB configuration indicated by the fourth indication information is an SSB configuration in one or more SSB configurations associated with the first cell.
[0244] In some embodiments, in the case that the RNTI scrambled PDCCH or DCI is transmitted on the third cell, the RNTI scrambled PDCCH or DCI can include fifth indication information and fourth indication information, where the fifth indication information can indicate the first SCell that activates SSB transmission; the fourth indication information can indicate the activated first SSB configuration, and the first SSB configuration indicated by the fourth indication information is an SSB configuration in one or more SSB configurations associated with the first SCell, and the first SCell can be a cell that requests SSB on demand. For example, in the case that the RNTI scrambled PDCCH or DCI is transmitted on the third cell, an indication bit (i.e., the fifth indication information) needs to be designed in the RNTI scrambled PDCCH or DCI, and the fifth indication information is used to indicate the identity of the SCell (such as a cell that supports SSB on demand) that activates SSB transmission. In addition, the fourth indication information can also be designed in the RNTI scrambled PDCCH or DCI, and the fourth indication information is used to directly indicate the identity of the activated SSB configuration.
[0245] Optionally, in some embodiments, as shown in FIG. 3E, the method further includes step S3502. In step S3502, the SSB transmission activation of the first SCell and the activated first SSB configuration are determined according to the RNTI scrambled PDCCH or DCI. For example, the terminal 101 receives the first information transmitted by the network device 102, and the first information can be the RNTI scrambled PDCCH or DCI. The terminal 101 can determine the SSB transmission activation of the first SCell and the activated first SSB configuration according to the RNTI scrambled PDCCH or DCI. The optional implementation of the RNTI scrambled PDCCH or DCI can refer to the description of the RNTI scrambled PDCCH or DCI in step S3501 above, and will not be described here.
[0246] Optionally, in some embodiments, the network device 102 activates the SSB transmission of the first SCell and activates the first SSB configuration through the RNTI scrambled PDCCH or DCI. Then, the network device 102 can use the activated first SSB configuration to transmit SSB. For example, the network device 102 can use the activated first SSB configuration to transmit SSB on the first SCell. Correspondingly, the terminal can receive SSB on the first SCell according to the activated first SSB configuration, i.e., the terminal 101 can receive SSB transmitted by the network device on the first SCell using the activated first SSB configuration.
[0247] In some embodiments, the other optional implementation modes described before or after the description of FIG. 3E can be referred to.

[0315] The embodiments of the present disclosure also propose a communication method, and the method related to the embodiments of the present disclosure can be applied to the communication system 100. The above-described method comprises but is not limited to the following step S6101.
[0316] At step S6101, the network device 102 sends the first information, and correspondingly, the terminal 101 receives the first information sent by the network device 102.
[0317] The optional implementation of step S6101 can refer to the optional implementation of step S3101 in FIG.3A, step S3201 in FIG.3B, step S3301 in FIG.3C, step S3401 in FIG.3D, step S3501 in FIG.3E, and other associated parts in the embodiments related to FIG.3A, FIG.3B, FIG.3C, FIG.3D, and FIG.3E, which are not described herein again.
[0318] In some embodiments, the above method can include the method described in the above terminal-side, network device-side, and other embodiments, which are not described herein again.
[0319] The following is an exemplary introduction to the above method.
[0320] Option 1: Define the first parameter, and the base station indicates to activate or deactivate the SSB configuration associated with the first parameter through the first parameter.
[0321] Embodiment: The first parameter is configured in the granularity of SSB configuration (first SSB configuration). The first SSB configuration can include the related parameters of SSB sending, such as period, frequency / band, SSB start and end position, etc. Exemplarily, the SCell can be associated with one or more first SSB configurations. Exemplarily, the first parameter is defined in the first SSB configuration, which indicates whether to activate / use this first SSB configuration. Exemplarily, the first parameter can be named SSBstatus, or other names. Exemplarily, the first parameter can take 1 bit as a value. Exemplarily, the value is “activated”. The configuration of the first parameter indicates to activate / use the first SSB configuration. The non-configuration of the first parameter indicates not to activate / use the first SSB configuration.
[0322] Another possible implementation is that the first parameter can be named SSBstatus, or other names. Exemplarily, the first parameter can take 1 bit as a value. Exemplarily, the value is “deactivated”. The configuration of the first parameter indicates not to activate / use the first SSB configuration. The non-configuration of the first parameter indicates to activate / use the first SSB configuration.
[0323] Another possible implementation is that the first parameter can take a value of 2 bits, for example, a first value, such as activated, indicates that the first SSB configuration is activated / used, and a second value, such as deactivated, indicates that the first SSB configuration is not activated / used. For example, the first value can be 1, and the second value can be 0, or there can be other value modes, which are not specifically limited in the disclosure.
[0324] Embodiment: The network device activates / deactivates the SSB transmission of the SCell through the first parameter. For example, if the first parameter associated with a first SSB configuration indicates that the first SSB configuration is activated, it means that the SCell activates the SSB transmission, and the SSB is transmitted using the first SSB configuration. If the first parameter associated with each first SSB configuration indicates that the first SSB configuration is deactivated, it means that the SCell deactivates the SSB transmission.
[0325] Option 2: Define a second parameter, and the base station indicates the activated SSB configuration through the second parameter.
[0326] Embodiment: The second parameter is configured in a cell granularity. For example, it is configured in ServingCellConfigCommon / ServingCellConfig / SCellConfig. For example, the cell is the cell based on which the SSB is requested to be transmitted. For example, each first SSB configuration is associated with a configuration identifier, such as index / ID / ConfigurationID, and the index is carried in the first SSB configuration when the network device configures the first SSB configuration. The initial state of the first SSB configuration is deactivated, for example, the default state of the first SSB configuration is deactivated. The second parameter indicates the activated first SSB configuration, for example, the index of the activated first SSB configuration. For example, if 4 configurations are supported, the second parameter can take a value of (0…3). A value of 0 indicates that the first SSB configuration associated with index 1 is activated, and so on. This is only an example, and other implementation modes are possible, which are not specifically limited.
[0327] Embodiment: The network device activates / deactivates the SSB transmission of the SCell through the second parameter. If the second parameter is configured, it means that the SCell activates the SSB transmission, and the SSB is transmitted using the first SSB configuration indicated by the second parameter. If the second parameter is not configured, it means that no first SSB configuration is activated, that is, the SCell deactivates the SSB transmission.
[0328] Embodiment: The second parameter is configured in a BWP granularity. For example, if BWP switching occurs, the UE uses the second parameter associated with the switched BWP or the second parameter associated with the default BWP.
[0329] Option 3: Define a new MAC CE which indicates the SCells whose SSB transmission is activated / deactivated and the activated SSB configuration.
[0330] Embodiment: The new MAC CE can contain 1 byte bitmap or 4 byte bitmap. The 1 byte bitmap MAC CE is associated with one LCID or one eLCID. The 4 byte bitmap MAC CE is associated with one LCID or one eLCID.
[0331] Embodiment: The 1 byte bitmap contains one R bit (reserved bit) and 7 bit positions, for example Ci (other naming is possible). The 7 bit positions are arranged in ascending order of SCell index. Each bit position corresponds to one SCell. For example, Ci is set to 1 to indicate that the SCell with SCell index i activates the SSB transmission, and Ci is set to 0 to indicate that the SCell with SCell index i deactivates the SSB transmission. The MAC CE can contain 0 or more first indication information in addition to the bitmap. For example, each SCell whose SSB transmission is activated is associated with one first indication information. Each SCell whose SSB transmission is deactivated is not associated with any first indication information. The 0 or more first indication information is arranged in ascending order of the index of the activated SCell. The first indication information indicates the index of the activated first SSB configuration. For example, the SSB ID indicates that the SCell whose SSB transmission is activated uses / activates the first SSB configuration associated with the SSB ID. For example, each first SSB configuration is associated with a configuration identifier, for example, index / ID / Configuration ID.
[0332] Embodiment 1: The Ci only corresponds to on-demand SCells, and is arranged according to the indexes of the on-demand SCells. For example, SCells with SCell indexes of 1, 3 and 5 are on-demand SCells, and Ci indicates SSB transmission of SCell index 1, C2 indicates SSB transmission of SCell index 3, and so on. The MAC CE can contain 0 or more first indication information in addition to the bitmap. For example, each SCell that activates SSB transmission is associated with a first indication information. An SCell that deactivates SSB transmission is not associated with a first indication information. The 0 or more first indication information of SSB is arranged in ascending order of the indexes of the activated on-demand SCells. The first indication information indicates the index of the activated first SSB configuration. For example, the SSB ID indicates that the SCell that activates SSB transmission uses / activates the first SSB configuration associated with the SSB ID. For example, each first SSB configuration is associated with a configuration identifier, such as an index / ID / Configuration ID.
[0333] Embodiment 1: The Ci only corresponds to on-demand SCells, and is arranged according to the indexes of the on-demand SCells. For example, SCells with SCell indexes of 1, 3 and 5 are on-demand SCells, and Ci indicates SSB transmission of SCell index 1, C2 indicates SSB transmission of SCell index 3, and so on. The MAC CE can contain 0 or more first indication information in addition to the bitmap. For example, each SCell that activates SSB transmission is associated with a first indication information. An SCell that deactivates SSB transmission is not associated with a first indication information. The 0 or more first indication information of SSB is arranged in ascending order of the indexes of the activated on-demand SCells. The first indication information indicates the index of the activated first SSB configuration. For example, the SSB ID indicates that the SCell that activates SSB transmission uses / activates the first SSB configuration associated with the SSB ID. For example, each first SSB configuration is associated with a configuration identifier, such as an index / ID / Configuration ID.
[0334] Embodiment 1: The Ci only corresponds to on-demand SCells, and is arranged according to the indexes of the on-demand SCells. For example, SCells with SCell indexes of 1, 3 and 5 are on-demand SCells, and Ci indicates SSB transmission of SCell index 1, C2 indicates SSB transmission of SCell index 3, and so on. The MAC CE can contain 0 or more first indication information in addition to the bitmap. For example, each SCell that activates SSB transmission is associated with a first indication information. An SCell that deactivates SSB transmission is not associated with a first indication information. The 0 or more first indication information of SSB is arranged in ascending order of the indexes of the activated on-demand SCells. The first indication information indicates the index of the activated first SSB configuration. For example, the SSB ID indicates that the SCell that activates SSB transmission uses / activates the first SSB configuration associated with the SSB ID. For example, each first SSB configuration is associated with a configuration identifier, such as an index / ID / Configuration ID.
[0335] Option 4: Define a new RNTI, the PDCCH / DCI scrambled by the new RNTI indicates the SCell(s) to activate / deactivate SSB transmission and the activated SSB configuration.
[0336] Embodiment: Define a new RNTI, the PDCCH / DCI scrambled by the new RNTI is transmitted on the SCell(s) to activate SSB transmission. A bitmap is defined in the DCI, each bit of the bitmap corresponds to one first SSB configuration, for example, set to 1 means to activate / use the first SSB configuration corresponding to the indication bit, set to 0 means to deactivate / not to use the first SSB configuration corresponding to the indication bit. Another implementation is to directly indicate the identity / index of the activated / used first SSB configuration through the DCI.
[0337] Embodiment: Define a new RNTI, the PDCCH / DCI scrambled by the new RNTI can be transmitted on the PCell or any SCell. On the basis of the above embodiment, additional indication bits are needed in the DCI to indicate the identity of the SCell(s) to activate SSB transmission.
