本公开各实施例可以应用于长期演进(Long Term Evolution，LTE)、LTE-Advanced(LTE-A)、LTE-Beyond(LTE-B)、SUPER 3G、IMT-Advanced、第四代移动通信系统(4th generation mobile communication system，4G)、)、第五代移动通信系统(5th generation mobile communication system，5G)、5G新空口(new radio，NR)、未来无线接入(Future Radio Access，FRA)、新无线接入技术(New-Radio Access Technology，RAT)、新无线(New Radio，NR)、新无线接入(New radio access，NX)、未来一代无线接入(Future generation radio access，FX)、Global System for Mobile communications(GSM(注册商标))、CDMA2000、超移动宽带(Ultra Mobile Broadband，UMB)、IEEE 802.11(Wi-Fi(注册商标))、IEEE 802.16(WiMAX(注册商标))、IEEE 802.20、超宽带(Ultra-WideBand，UWB)、蓝牙(Bluetooth(注册商标))、陆上公用移动通信网(Public Land Mobile Network，PLMN)网络、设备到设备(Device-to-Device，D2D)系统、机器到机器(Machine to Machine，M2M)系统、物联网(Internet of Things，IoT)系统、车联网(Vehicle-to-Everything，V2X)、利用其他通信方法的系统、基于它们而扩展的下一代系统等。此外，也可以将多个系统组合(例如，LTE或者LTE-A与5G的组合等)应用。
需要说明的是，随着人们对速率、延迟、高速移动性、能效的追求，以及未来生活中业务的多样性、复杂性，为此3GPP(3rd Generation Partnership Project,第三代合作伙伴计划)国际标准组织开始研发5G。5G的主要应用场景为：增强移动超宽带(Enhanced Mobile Broadband，eMBB)、低时延高可靠通信(Ultra-Reliable Low-Latency Communications，URLLC)、大规模机器类通信(Massive Machine Type Communication，mMTC)。eMBB仍然以用户获得多媒体内容、服务和数据为目标，其需求增长十分迅速。另一方面，由于eMBB可能部署在不同的场景中，便如室内，市区，农村等，其能力和需求的差别也比较大，所以不能一概而论，必须结合具体的部署场景详细分析。URLLC的典型应用包括：工业自动化，电力自动化，远程医疗操作(手术)，交通安全保障等。mMTC的典型特点包括：高连接密度，小数据量，时延不敏感业务，模块的低成本和长使用寿命等。
由于5G基站的能耗是LTE基站的四倍，所以网络节能是运营商降低运营5G系统成本的重要手段。在一些实施例中，为了处于RRC连接态(RRC_CONNECTED)终端节能，引入了WUS(wake up signal，唤醒信号)。在UE C-DRX(Connected Discontinuous Reception，连接态下的不连续接收)的on duration(持续时间)的前面的一个offset(偏移)定义一个发送WUS信号的duration，在该WUS duration期间发WUS信号，即DCI 2-6，通过PS-RNTI(Power Saving RNTI，节约能源RNTI)加扰，用于指示终端是否在接下来的UE C-DRX onduration期间醒过来监听PDCCH(Physical Downlink Control Channel，物理下行控制信道)。
在一些实施例中，为了处于RRC_IDLE/INACTIVE(RRC空闲态/非激活态)终端节能，引入了paging WUS(寻呼唤醒信号)。即在PO(paging occasion，寻呼时机)之前的某个时刻开始发送paging WUS，即PEI(paging early indication，寻呼早期指示)，用于指示终端是否在该PO监听寻呼调度信息。其中PEI为DCI 2-7，通过PEI-RNTI(寻呼早期指示无线网络临时标识符)加扰。
在一些实施例中，网络节能(NES)已经支持inter-band CA场景下的SSB-less SCell，SSB-less的SCell不发送SSB(Synchronization Signal Block，同步信号块)，终端通过reference cell(参考小区)的SSB来实现SCell(Secondary Cell，辅小区)上的时频同步，L1/L3(层1/层3)测量、SCell激活等功能，但是inter-band CA场景下的SSB-less有很多限制，例如PCell(Primary Cell，主小区)和SCell共站(co-located)并且只能工作在频段FR1。不支持频段FR2和非共站的场景。
在一些实施例中，R19 NES支持FR2和非共站场景，按需SSB(on demand SSB)可以作为对SSB传输的增强，用于SSB-less操作未涵盖的场景，以实现网元增益，并确保适当/增强的SCell功能，包括时间/频率同步，L1/L3测量和SCell激活。终端如果需要获取on-demand SSB SCell(按需请求SSB的SCell)的SSB，则可以通过UL WUS(wake up signal)唤醒信号来向on-demand SSB SCell请求SSB。也就是说，SCell的SSB是基于请求发送的，或者是按需请求发送的。另一种可能的实现方式是：网络设备基于实现在SCell上触发SSB发送，例如网络设备需要获取该SCell的RRM(Radio ResourceManagement，无线资源管理)测量报告，网络设备需要通过指示信息通知终端。
相关技术中，载波聚合场景下的小区可以包括支持网络节能(NES)模式的辅小区和非节能的辅小区(也称为正常小区，即按照SSB的传输周期发送SSB的辅小区)。支持网络节能(NES)模式的辅小区可以支持按需发送同步信号块on-demand SSB功能，例如支持on-demand SSB功能的辅小区可以基于网络设备实现触发发送SSB。然而，如何让终端能够及时了解辅小区上的SSB传输情况，是亟待解决的问题。
为此，本公开实施例提供一种通信方法及装置，可以通过网络设备向终端发送信息来通知终端，网络设备激活或去激活哪个或哪些辅小区上的SSB传输，便于终端能够及时了解该辅小区上的SSB传输情况，从而便于终端执行相应操作。
图2A是根据本公开实施例示出的通信方法的交互示意图。如图2A所示，本公开实施例涉及通信方法可应用于通信系统100，上述方法包括但不限于如下步骤。
步骤S2101，终端101接收网络设备102发送的第一信息，该第一信息用于指示至少一个辅小区(SCell)上的SSB(Synchronization Signal Block，同步信号块)传输激活或去激活。
在一些实施例中，至少一个辅小区上的SSB传输激活例如可以是指该至少一个辅小区上的SSB开始发送。至少一个辅小区上的SSB传输去激活例如可以是指该至少一个辅小区上的SSB停止发送。
在一些实施例中，上述第一信息可以是网络设备102触发至少一个辅小区上的SSB传输后发送给终端101的。示例性的，支持按需发送同步信号块on-demand SSB功能的小区可以基于网络设备102实现触发发送SSB，网络设备102触发该支持on-demand SSB功能的小区上的SSB发送后，向终端101发送第一信息，相应的，终端101接收网络设备102发送的该第一信息，该第一信息用于指示至少一个辅小区上的SSB传输激活。示例性的，支持按需发送同步信号块on-demand SSB功能的小区可以基于网络设备实现停止发送SSB，网络设备停止发送该支持on-demand SSB功能的小区上的SSB，并向终端101发送第一信息，该第一信息用于指示至少一个辅小区上的SSB传输去激活。在一些实施例中， 该至少一个辅小区可以包括至少一个第一辅小区和/或至少一个第二辅小区。在一些实施例中，该至少一个辅小区可以包括至少一个第一辅小区。其中，第一辅小区为支持按需发送同步信号块on-demand SSB功能的小区(也可以用on-demand SCell表示)，第二辅小区为正常小区。示例性的，该正常小区例如可以是指非节能的辅小区，也即是：该正常小区可以是指按照SSB的传输周期发送SSB的辅小区。或者，该支持on-demand SSB功能的小区也可以有其他名称，本公开对此不作具体限定。
在一些实施例中，该第一信息可以为MAC CE(Medium Access Control Control Element，媒体接入控制控制元素)，该MAC CE关联一个LCID(logical channel identify，逻辑信道标识)或eLCID(enhanced logical channel identify，增强逻辑信道标识)。示例性的，该第一信息的标识为LCID，该第一信息的标识是从LCID预留池中选取的一个LCID，并且其中，LCID预留池包括至少一个LCID。示例性的，该第一信息的标识为eLCID；该第一信息的标识是从eLCID预留池中选取的一个eLCID，并且其中，eLCID预留池包括至少一个eLCID。
在一些实施例中，该第一信息可以为MAC CE，该MAC CE中定义的第一位图包括至少一个第一指示位，该至少一个第一指示位中的每一个第一指示位对应于上述至少一个辅小区之中一个辅小区，每个第一指示位用于指示对应辅小区上的SSB传输激活或去激活，上述至少一个辅小区包括至少一个第一辅小区和/或至少一个第二辅小区，该第一辅小区为支持on-demand SSB功能的小区，该第二辅小区为正常小区。示例性的，该MAC CE的发送可以适用于以下任一场景：配置了SCell但还未激活该SCell；SCell激活期间；SCell激活后。
在一些实施例中，上述第一指示位对应的辅小区为第一辅小区。其中，该第一指示位为第一值，用于指示激活该第一指示位对应的第一辅小区上的SSB传输；该第一指示位为第二值，用于指示去激活该第一指示位对应的第一辅小区上的SSB传输。示例性的，对于至少一个辅小区中的第一辅小区，则第一辅小区关联的第一指示位为第一值，用于指示激活第一辅小区上的SSB传输；该第一辅小区关联的第一指示位为第二值，用于指示去激活第一辅小区上的SSB传输。示例性的，以第一值为1，第二值为0为例，上述第一辅小区关联的第一指示位为1，则表示激活该第一辅小区上的SSB传输；上述第一辅小区关联的第一指示位为0，则表示去激活该第一辅小区上的SSB传输。可以理解，上述第一辅小区关联的第一指示位的取值方式还可以采用其他数值，在此本公开对此不做具体限定，也不再赘述。
在一些实施例中，上述第一指示位对应的辅小区为第二辅小区，则终端101忽略该第一指示位；或者，该第一指示位为第二值。示例性的，对于至少一个辅小区中的第二辅小区，终端101忽略该第二辅小区关联的第一指示位，或者，该第二辅小区关联的第一指示位为第二值。示例性的，该第二值可以为0，或者也可以是其他值，在此本公开对此不做具体限定。
在一些实施例中，终端101未配置第一指示位对应的辅小区，则终端101忽略该第一指示位。示例性的，某第一指示位对应的辅小区关联的小区标识为A，但是终端未配置该小区标识为A的辅小区，终端101忽略该第一指示位。
在一些实施例中，上述MAC CE中的第一位图的位图大小可以为1字节，也可以是4字节，或者还可以其他位图大小，在此本公开对此不做具体限定。需要说明的是，本文中主要是以MAC CE中的位图大小为1字节为例对MAC CE的具体形式进行描述，也就是说，MAC CE中的位图大小还可以是其他字节大小，其具体形式的实现方式与位图大小为1字节的MAC CE的实现方式类似，可以参见以MAC CE中的位图大小为1字节为例对MAC CE的具体形式的描述。
在一些实施例中，上述MAC CE中还可以定义SSB传输信息，其中，该SSB传输信息的数量与激活SSB传输的辅小区的数量相同，每个激活SSB传输的辅小区关联一个SSB传输信息，且该SSB传输信息按照激活SSB传输的辅小区的索引大小排序，示例性的，该SSB传输信息按照激活SSB传输的辅小区的索引从小到大排序或者从大到小排序。

值得注意的是，载波聚合场景下，第一辅小区可以基于网络实现触发发送SSB，网络设备触发SCell上的SSB发送后，需要通过指示信息指示终端，然而，该指示信息的具体形式以及该指示信息的使用场景是否需要明确的问题。基于此，本公开提出了一种发送SSB的指示方法，下面将结合具体实施例来进行详细描述。
在一些实施例中，定义新的MAC CE，指示SCell上的SSB传输激活/去激活。
示例性的，该新的MAC CE可以是1byte bitmap(位图大小为1字节)也可以是4byte bitmap(位图大小为4字节)。该1byte bitmap的MAC CE关联一个LCID或者一个eLCID，该4byte bitmap关联一个LCID或者一个eLCID。
示例性的，该1byte bitmap包含一个R bit(预留bit)和7个指示位例如Ci(可以有其他命名)。按照Scellindex从小到大排列，该7个指示位的每一个指示位对应一个SCell，例如C1对应SCellindex 1的SCell，以此类推。如果一个MAC实体(表示一个终端)配置了SCellindex i的SCell，这个域就指示了SCellindex i的SCell的SSB传输激活/去激活状态。示例性的，激活表示该SCell上的SSB开始发送，去激活表示该SCell上的SSB停止发送。如果一个MAC实体没有配置SCellindex i的SCell或者SCellindex i对应的SCell不是on-demand SSB SCell，终端就忽略这个Ci。或者，SCellindex i对应的SCell不是on-demand SSB SCell，该指示位置为0。示例性的，Ci置为1表示激活SCellindex i的SCell的SSB，Ci置为0表示去激活SCellindex i的SCell的SSB。
示例性的，该Ci只对应on-demand SCell，按照on-demand SCell的index排列，示例性的，SCellindex为1、3、5的SCell为on-demandSCell，则C1指示激活/去激活Scellindex 1的SSB发送，C2指示激活/去激活Scellindex 3的SSB发送，以此类推。
示例性的，该4byte bitmap包含一个Rbit和31个指示位。其他具体细节参考上述1byte bitmap的 相关描述，此处不再赘述。
示例性的，该MAC CE除了bitmap以外可以包含0个或多个SSB传输信息，例如包括以下至少之一：SSB起始位置；SSB结束位置；SSB持续duration；SSB传输burst的数目；两个连续burst之间的间隔等。示例性的，起始位置/结束位置可以通过无线帧、无线子帧、时隙、时域符号等表示，示例性的，起始位置/结束位置可以是相对时间位置，例如距离该MAC CE的一个offset，指示SSB起始位置/结束位置。示例性的，SSB持续duration可以通过时、分、秒、毫秒、微秒、纳秒等进行计量或者通过无线帧、无线子帧、时隙、时域符号等进行计量。示例性的，每个激活了SSB发送的SCell关联一个SSB传输信息。去激活了SSB发送的SCell没有关联的SSB传输信息。该0个或多个SSB传输信息按照激活的SCell的index升序排列或者按照激活的on-deamnd SCell的index升序排列。可选的，该SSB传输信息也可以通过RRC信令(如本公开中的第一RRC信令)半静态配置。
示例性的，该新的MAC CE适用于场景1、场景2、场景3中之一。其中，场景1可以是指配置(或添加)了SCell但是还未激活该SCell；场景2是指SCell激活期间；场景3是指SCell激活后。
示例性的，作为一种可能的实现方式，重用现有的SCell激活/去激活MAC CE。示例性的，该MAC CE适用于场景2。例如终端接收到SCell激活/去激活MAC CE，该Ci指示bit除了指示SCellindex i的SCell的激活/去激活状态，还可以指示SCellindex i的SCell的SSB传输激活/去激活状态，例如Ci为1，指示SCellindex i的SCell激活且SSB传输激活。Ci为0，指示SCellindex i的SCell去激活且SSB去激活。可选的，该MAC CE还可以包含0个或多个SSB传输信息，例如包括以下至少之一：SSB起始位置；SSB结束位置；SSB持续duration；SSB传输burst的数目；两个连续burst之间的间隔等。该0个或多个SSB传输信息按照激活的SCell的index升序排列。或者也可以通过RRC信令(如本公开中的第一RRC信令)半静态配置SSB传输信息。
示例性的，确定SCellindexi关联的SCell不是on-demand SSB SCell，ci为1只表示激活该SCell，一种可能的方式是该SCell没有对应的SSB传输信息，也就是说只有激活的且on-deamnd SSB的SCell才有对应的SSB传输信息，(假设配置了SCellindex为1-5的SCell，其中SCellindex为1、3、5的SCell为on-demandSCell，若指示SCellindex为1、2、4和5的SCell激活，则只有SCellindex为1和5的SCell有对应的SSB传输信息，激活的SCellindex为2和4的SCell没有对应的SSB传输信息)；一种可能的方式是该SCell有对应的SSB传输信息，但该域置为0或者其他特殊取值。如果Ci为0，则该SCell没有对应的SSB传输信息。
示例性的，确定SCellindexi关联的SCell是on-demand SSB SCell如果on-demand SCell，ci为1表示激活SCell和激活SSB传输。该SCell有对应的SSB传输信息。如果Ci为0，表示去激活该SCell和去激活SSB传输，该SCell没有对应的SSB传输信息。
在一些实施例中，定义新的RNTI，指示SCell上的SSB传输激活/去激活。
示例性的，定义新的RNTI/DCI，该RNTI加扰的PDCCH用于指示激活/去激活SCell上的SSB传输。该方案适用于场景3。网络设备如果激活/去激活某个SCell的SSB，则在该SCell上发送该RNTI加扰的PDCCH。示例性的，激活和去激活可以关联不同的RNTI，示例性的激活和去激活关联相同的RNTI。具体的，激活和去激活关联相同的RNTI，需要有额外的指示信息(如本文中的第四指示信息)指示激活或者去激活。
示例性的，可以通过RRC信令(如本公开中的第一RRC信令)半静态配置SSB传输信息，例如 包括以下至少之一：SSB起始位置；SSB结束位置；SSB持续duration；SSB传输burst的数目；两个连续burst之间的间隔等。
示例性的，定义新的RNTI/DCI，该RNTI加扰的PDCCH(如本文中的第一RNTI加扰的PDCCH)用于指示激活/去激活SCell上的SSB传输。该方案适用于场景1，场景2，场景3。该RNTI加扰的PDCCH可以在PCell或者其他SCell上发送，示例性的，激活和去激活可以关联不同的RNTI，示例性的激活和去激活关联相同的RNTI。具体的，激活和去激活关联相同的RNTI，需要有额外的指示信息指示激活或者去激活。该RNTI加扰的PDCCHDCI/RNTI加扰的PDCCH中携带激活/去激活的SCell的标识指示信息(如本公开中的第一指示信息或第二指示信息)。例如一个bitmap，每个bit对应一个SCell。置为1指示该SCell激活SSB传输，置为0指示该SCell去激活SSB传输。
另外一种可能的实现方式，首先通过RRC配置将SCell分组，通过DCI将一整个组的SCell激活或者去激活SSB发送，这个组里的SCell都是on-demand SSB SCell。该DCI/RNTI加扰的PDCCH中携带激活/去激活的SCell组的指示信息(如本公开中的第五指示信息)。例如一个bitmap，每个bit对应一个SCell组，置为1指示激活该SCell组的SSB传输，置为0指示去激活该SCell组的SSB传输。
在一些实施例中，定义新的RRC信令(如本公开中的第二RRC信令)，指示SCell上的SSB传输激活/去激活。
示例性的，定义新的RRC信令，该RRC信令指示了激活/去激活SSB传输的SCell，例如指示激活/去激活SSB传输的SCell index，示例性的，还可以包含SSB传输信息，例如包括以下至少之一：SSB起始位置；SSB结束位置；SSB持续duration；SSB传输burst的数目；两个连续burst之间的间隔等。
