Description

一种通信方法及装置 技术领域
本申请涉及无线通信技术领域，特别涉及一种通信方法及装置。
背景技术
为了降低终端设备的功耗，可以采用不连续接收(discontinuous reception，DRX)机制避免终端设备长期处于唤醒状态。当配置DRX时，在一个DRX内，终端设备的状态可以分为DRX激活(active)态和DRX非激活(non-active)态。终端设备处于DRX active态的时间称为激活时间(active time)。在DRX激活时间内，终端设备会持续监听物理下行控制信道(physical downlink control channel，PDCCH)。在DRX激活时间外，终端设备可以进入睡眠状态，不去监听PDCCH，从而节省UE功耗。
为进一步节省终端设备的功耗，在DRX机制下引入了休眠(dormant)下行带宽部分(bandwidth part，BWP)机制。网络设备可以通过在下行控制信息(downlink control information，DCI)中的辅小区休眠指示(SCell dormancy indication)域指示辅小区(secondary cell，SCell)是休眠(dormancy)还是非休眠(non-dormancy)。如果终端设备根据辅小区休眠指示域确定一个SCell的激活下行BWP是休眠下行BWP，则会将这个SCell的下行激活BWP切换到休眠下行BWP。
目前协议规定，辅小区休眠指示域只能在主小区(primary cell，PCell)上发送。考虑到PCell的负载有可能较高，后续协议可能会引入通过在特殊辅小区(special SCell，sScell)上发送的DCI进行PCell的数据调度。

具体实施方式
下面将结合附图对本申请实施例作进一步地详细描述。
本申请实施例的技术方案可以应用于各种通信***，例如：长期演进(long term evolution，LTE)***、NR***以及下一代通信***等，在此不做限制。
本申请实施例中，终端设备，可以为具有无线收发功能的设备或可设置于任一设备中的芯片，也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站等。本申请实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端等。
网络设备，可以是NR***中的下一代基站(next Generation node B，gNB)，可以是LTE***中的演进型基站(evolutional node B，eNB)等。
如图1所示，为适用于本申请的一种网络架构示意图。图1中，终端设备通过双链接(dual connectivity，DC)方式和多个小区建立链接，这些小区分为两组：主小区组(master cell group，MCG)和辅小区组(secondary cell group，SCG)。如果没有进行双链接，那么和终端设备通信的一组小区就是MCG。
MCG中包括一个主小区(primary cell，PCell)和至少一个辅小区(secondary cell，SCell)；SCG中包括一个主辅小区(primary secondary cell，PSCell)和至少一个SCell。MCG下的PCell和MCG下的SCell通过载波聚合(carrier aggregation，CA)技术联合在一起。SCG下的PSCell和SCG下的SCell也是通过载波聚合技术联合在一起。
为了描述方便，本申请实施例中，如果没有明确说明，PCell可以指MCG中的PCell，也可以指SCG中的PSCell。
本申请实施例中，处于无线资源控制(radio resource control，RRC)空闲(idle)态或RRC非激活(inactive)态的终端设备可以按照非连续接收(discontinuous reception，DRX)方式接收数据。如图2所示，在一个DRX周期内，终端设备的状态可以分为DRX激活(active)态和DRX非激活(non-active)态。终端设备处于DRX active态的时间称为激活时间(active time)。在DRX激活时间内，终端设备会持续监听PDCCH。在DRX激活时间外，终端设备可以进入睡眠状态，不去监听PDCCH，从而节省功耗。
第三代伙伴计划(the 3rd generation partnership project，3GPP)版本16(release-16，Rel-16)引入了CA时DRX机制下的休眠(dormant)下行BWP机制。一个SCell可以配置最多一个休眠下行BWP，如果一个终端设备的一个SCell的激活下行BWP是休眠下行BWP，终端设备停止在这个SCell上监测物理下行控制信道(physical downlink control channel，PDCCH)，也停止监测调度这个SCell的PDCCH，但可以继续进行信道状态信息(channel state information，CSI)测量，自动增益控制和波束管理。如果一个SCell的下行激活BWP是休眠下行BWP，那么这个SCell的上行发送也会停止。
需要注意的是，PCell和配置了物理上行控制信道(physical uplink control channel，PUCCH)的SCell不可以配置休眠下行BWP。
网络侧可以对SCell进行分组，在DRX周期中的active time内可以将配置了休眠下行BWP的SCell分为最多5组；在DRX周期中的active time外，也可以将配置了休眠下行BWP的SCell分为最多5组。以下为了描述方便，将DRX周期中的active time简称为激活时间或者active time。
SCell的dormancy和非休眠(non-dormancy)之间的切换通过下行控制信息(downlink control information，DCI)指示，有以下3种指示方式：
方式一：active time内，通过DCI格式(format)0_1或者1_1中的辅小区休眠指示(SCell dormancy indication)域指示SCell是dormancy还是non-dormancy，DCI还可以同时调度数据。辅小区休眠指示域包括至少一个比特，每一个比特对应其中一个active time内的休眠小区组(group)。当一个比特的取值为0，该比特对应的休眠小区组里的每一个SCell上的激活BWP都切换到dormant BWP；当一个比特的取值为1，如果该比特对应的休眠小区组里的每一个SCell上，终端设备正处于non-dormant BWP，那么终端设备继续工作在该non-dormant BWP上，如果终端设备正处于dormant BWP，那么终端设备切换到第一非休眠(first non-dormant)BWP。
方式二：active time内，通过DCI format 1_1中的特定域指示SCell是dormancy还是 non-dormancy，DCI不可以同时调度数据。此种指示方法中，每一个比特对应一个SCell，用来指示每一个SCell是dormancy还是non-dormancy。
方式三：active time外，通过DCI format 2_6中的辅小区休眠指示域指示SCell是dormancy还是non-dormancy。指示方式和方式一基本类似，区别在于DCI format 2_6为组公共DCI，可以向多个终端设备发送。
需要注意的是，辅小区休眠指示域只能在主载波上发送，且用DCI format 0_1或DCI format 1_1指示辅小区休眠时，只在DCI不包含载波指示域(carrier indicator field，CIF)，或者载波指示域为0时，辅小区休眠指示域才有效。这里，PCell上发送的DCI中不包含载波指示域，代表PCell的DCI只调度PCell自己；PCell上发送的DCI中包含载波指示域时，代表PCell的DCI可以调度自己或SCell，当载波指示域为0时，这个DCI用来调度PCell自己。
需要说明的是，终端设备可以在搜索空间中监听PDCCH，PDCCH上承载下行控制信道(downlink controlinformation，DCI)。一个搜索空间集中包含至少一个PDCCH候选。一个PDCCH候选是一组时频资源，上面可能发送一个终端设备的PDCCH，也有可能不发送。终端设备可以对一个PDCCH候选进行检测，以确定是否存在自己的PDCCH。搜索空间集的类型有两种：公共搜索空间(common search space，CSS)和终端设备特定搜索空间(UE-specific search space，USS)。
DCI有不同的格式(format)，不同的DCI format的作用不同，承载的内容不同，例如DCI format 0_0和DCI format 0_1承载上行调度，DCI format 1_0、DCI format 1_1和DCI format 1_2承载下行调度。
CSS类型的搜索空间集里传输的DCI format包含DCI format 2_0、DCI format 2_1、DCI format 2_2、DCI format 2_3、DCI format 2_4、DCI format 2_5、DCI format 2_6、DCI format 0_0和DCI format 1_0等。
USS类型的搜索空间能传输的DCI format包含DCI format 0_0、DCI format 0_1、DCI format 1_0、DCI format 1_1和DCI format 1_2等。
目前的跨载波调度中，辅小区是不能调度主小区的，考虑到主小区的负载有可能较高，后续协议可能会引入用辅小区调度主小区。本申请实施例中将可以通过DCI来调度PCell的SCell称为特殊辅小区(special SCell，sScell)。本申请实施例提供一种方法，可以实现在Scell通过DCI调度PCell的情况下，既能够保证灵活的通过DCI发送辅小区休眠指示域，又能够尽量减小DCI的开销。
本申请描述的网络架构以及业务场景是为了更加清楚的说明本申请的技术方案，并不构成对于本申请提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请提供的技术方案对于类似的技术问题，同样适用。
本申请中，以网络设备与终端设备之间交互为例进行说明，网络设备执行的操作也可以由网络设备内部的芯片或模块执行，终端设备执行的操作也可以由终端设备内部的芯片或模块执行。
如前所述，本申请实施例可以应用于辅小区调度主小区的场景中，在该场景中，如图3所示，终端设备与网络设备可能存在以下的信息交互和处理过程。
步骤301：网络设备向终端设备发送辅小区信息。
辅小区信息用于指示能够调度PCell的Scell，具体过程并不限定，在此不再赘述。
步骤302：网络设备配置辅小区休眠指示域对应的SCell组，并将配置的SCell组指示给终端设备。
其中步骤301和步骤302的顺序并不限定，可以先后执行，也可以同时执行。
步骤303：网络设备在PCell或sScell上发送的DCI。
该DCI的格式可以为DCI format 0_1或者1_1或者2_6，该DCI中可以包括辅小区休眠指示域，也可以不包括辅小区休眠指示域，具体将在后面详细描述。
步骤304：终端设备获取包括辅小区休眠指示域的DCI。
需要说明的是，步骤301可以采用现有技术实现，本申请实施例将涉及到步骤302至步骤304，具体内容将在后面详细描述。
实施例一：
当通过辅小区调度主小区中的数据传输时，网络设备可以通过辅小区以及主小区发送包括辅小区休眠指示域的DCI，为例降低DCI的开销，并保证调度的灵活性，本申请实施例中，可以预先约定在发送辅小区休眠指示域的小区，下面将详细描述。
如图4所示，为本申请实施例提供的一种通信方法流程示意图，该方法包括：
S401：网络端设向终端设备发送第一配置信息；
所述第一配置信息指示至少一个休眠小区组，所述至少一个休眠小区组中的小区为一个小区组中的辅小区，所述至少一个休眠小区组中的小区被配置了休眠下行BWP；该小区组可以为主小区组，也可以为辅小区组；该小区组中包括主小区和至少一个辅小区。
所述至少一个休眠小区组可以是网络设备针对active time内配置的，也可以是网络设备针对active time外配置的。
S402：网络端设向终端设备发送第二配置信息。
其中，第二配置信息用于指示在第一小区中监测第一下行控制信息的资源，第一下行控制信息用于调度所述小区组中的主小区的数据传输；第一小区是所述小区组中的一个辅小区。
第一下行控制信息的格式为DCI format 0_1或者DCI format 1_1，或者第一下行控制信息可以是指能够携带辅小区休眠指示域的DCI。为了描述方便，本申请实施例中，可以将DCI format 0_1简称为0_1，将DCI format 1_1简称为1_1，将DCI format 2_6简称为2_6。
S403：终端设备接收来自网络设备的第一配置信息，并接收来自网络设备的第二配置信息。
S404：网络设备在第一小区中第二配置信息指示的资源上向终端设备发送第一下行控制信息。
其中，辅小区休眠指示域用于指示至少一个休眠小区组为休眠状态或非休眠状态。
S405：终端设备在所述第一小区中所述第二配置信息指示的资源上监测来自网络设备的所述第一下行控制信息。
其中，第一下行控制信息包括辅小区休眠指示域或者不包括辅小区休眠指示域；所述辅小区休眠指示域用于指示所述至少一个休眠小区组为休眠状态或非休眠状态。
终端设备可以根据所述第一下行控制信息包括辅小区休眠指示域或者不包括辅小区休眠指示域，监测所述第一下行控制信息。具体的，第一下行控制信息包括辅小区休眠指示域时，第一下行控制信息的长度为第一长度，终端设备可以根据第一长度监测所述第一下行控制信息；第一下行控制信息不包括辅小区休眠指示域时，第一下行控制信息的长度 为第二长度，终端设备可以根据第二长度监测所述第一下行控制信息。
举例来说，辅小区休眠指示域包括至少一个比特，每一个比特对应其中一个休眠小区组。当辅小区休眠指示域中的一个比特的取值为0，指示该比特对应的休眠小区组里的每一个辅小区为休眠状态；如果该比特对应的休眠小区组里的任一个辅小区中，终端设备工作在该辅小区的非休眠BWP中，则终端设备切换到该辅小区的休眠BWP中；
当辅小区休眠指示域中的一个比特的取值为1，指示该比特对应的休眠小区组里的每一个辅小区为非休眠状态；如果该比特对应的休眠小区组里的任一个辅小区中，终端设备工作在该辅小区的非休眠BWP中，那么终端设备继续工作在该非休眠BWP上，如果终端设备工作在该辅小区的休眠BWP中，那么终端设备切换到该辅小区的第一非休眠(first non-dormant)BWP。
本申请实施例中，第一下行控制信息具体是否包括辅小区休眠指示域，可能存在多种情况，下面分别进行描述。以下描述的情况一至情况三中，第一下行控制信息的格式为0_1，1_1中的一项或多项。
情况一：如果在主小区上配置了用于监测第二下行控制信息的资源，第二下行控制信息的格式为0_1和1_1中的一项或多项时，存在以下几种实现方式：
实现方式一：第一下行控制信息包括辅小区休眠指示域，第二下行控制信息包括辅小区休眠指示域；
实现方式二：第一下行控制信息包括辅小区休眠指示域，第二下行控制信息不包括辅小区休眠指示域；
实现方式三：第一下行控制信息不包括辅小区休眠指示域，第二下行控制信息包括辅小区休眠指示域。
情况二：如果在主小区上没有配置用于监测第二下行控制信息的资源，第二下行控制信息的格式为0_1和1_1中的一项或多项时，第一下行控制信息包括辅小区休眠指示域。
情况三：网络设备通过第三配置信息指示第一下行控制信息和第二下行控制信息中的至少一个包括辅小区休眠指示域。
终端设备可以根据所述第三配置信息确定第一下行控制信息和所述第二下行控制信息中的至少一个包括所述辅小区休眠指示域，第二下行控制信息的格式为0_1和1_1中的一项或多项。
综上所述，当网络设备可以通过主小区和第一小区来调度主小区中的数据传输时，可能存在以下实现方式：
第一种实现方式，包括以下几种情况：
情况1：在主小区上发送的第二DCI中包含辅小区休眠指示域，在第一小区上发送的第一DCI不包含辅小区休眠指示域；
其中，第一DCI的格式为0_1，1_1中的一项或多项；第二DCI的格式为0_1，1_1中的一项或多项。
情况2：在第一小区上发送的第一DCI中包含辅小区休眠指示域，在主小区上发送的第二DCI不包含辅小区休眠指示域；
情况3：网络设备通过高层信令指示在主小区，或第一小区，或主小区和第一小区，上发送的DCI中包含辅小区休眠指示域。
第二种实现方式：当只有在第一小区上发送的0_1或1_1第一DCI能调度主小区中的 数据传输时，在第一小区上发送的第一DCI中包含辅小区休眠指示域。其中，只有在第一小区上发送的第一DCI能调度主小区中的数据传输，是指在主小区上没有配置USS，或者在主小区上不监测0_1和1_1的DCI，而在第一小区上配置了USS，或者在第一小区上监测0_1和1_1中的一项或多项的DCI。
需要注意的是，目前的标准中，只有0_1或者1_1这两类能调度终端特定(UE-specific)数据传输的DCI可以包含辅小区休眠指示域，如果后续协议增加了其他格式的能调度终端特定(UE-specific)数据传输的DCI，则0_1或者1_1可以拓展到这些DCI上。
举例来说，根据上面的方案，可能存在如下操作：
如果仅小区1上有USS，切换到小区1和小区2上都有USS，且协议规定或高层指示当小区1和小区2上都有USS时，只有小区2上发送的DCI format 0_1&1_1中包含辅小区休眠指示域时。
当小区2上的USS生效时，小区1上的DCI format 0_1&1_1的DCI size减小，即从包含辅小区休眠指示域切换到不包含辅小区休眠指示域。
如果小区1和小区2上都有USS，切换到仅小区1上有USS，且协议规定或高层指示当小区1和小区2上都有USS时，只有小区2上发送的DCI format 0_1&1_1中包含辅小区休眠指示域时。
当小区2上的USS失效时，小区1上的DCI format 0_1&1_1的DCI size增大，即从不包含辅小区休眠指示域切换到包含辅小区休眠指示域。
通过实施例一提供的方法，可以在保证灵活的辅小区休眠指示域发送时，尽量减小DCI的开销。
实施例二：
本申请实施例中，提供一种辅小区分组的方法，可以应用于通过辅小区调度主小区中的数据传输的场景中。如图5所示，为本申请实施例提供的一种通信方法流程示意图，该方法包括：
S501：网络设备向终端设备发送配置信息。
S502：网络设备向终端设备发送第一下行控制信息。
S503：终端设备接收来自网络设备的配置信息，并在第一小区中接收来自网络设备的第一下行控制信息。
其中，所述配置信息指示第一休眠小区组，所述第一休眠小区组中的小区为一个小区组中的辅小区，所述第一休眠小区组中的所述小区被配置了休眠下行BWP；所述小区组为主小区组或辅小区组；所述第一休眠小区组包括第一小区，所述第一小区为所述小区组中调度主小区的辅小区，具体的，可以通过第一小区发送下行控制信息来调度所述小区组中的主小区的数据传输。
需要说明的是，配置信息可能配置了多个休眠小区组，本申请实施例并不限定。举例来说，图5的流程中，网络设备对一个小区组中的辅小区进行分组时，针对active time内可以将配置了休眠下行BWP的辅小区分为最多5组；针对active time外，也可以将配置了休眠下行BWP的辅小区分为最多5组，第一小区可以包含在其中一个组内。网络设备可以将最终的分组情况指示给终端设备。
图5的流程中，终端设备还可能在第一小区中接收来自网络设备的第一下行控制信息。第一下行控制信息可以包括第一辅小区休眠指示域，所述第一辅小区休眠指示域用于指示 第一休眠小区组为休眠状态或者非休眠状态。第一辅小区休眠指示域具体如何指示第一休眠小区组为休眠状态或者非休眠状态，本申请并不限定，例如可以参考前面的描述，在此不再赘述。
结合图5的流程，终端设备接收来自网络设备的配置信息之后，可能存在以下实现方式。
实现方式一：
如果终端设备在第一小区中接收来自网络设备的第一下行控制信息，第一下行控制信息包括第一辅小区休眠指示域时，则将所述第一休眠小区组中除了第一小区之外的辅小区，设置为所述第一辅小区休眠指示域指示的休眠状态或者非休眠状态。
其中，如果所述第一辅小区休眠指示域指示所述第一休眠小区组为休眠状态，保持所述第一小区为非休眠状态，并将所述第一休眠小区组中除了第一小区之外的辅小区，设置为休眠状态。
可选地，第一休眠小区组为针对激活时间内配置的，第一下行控制信息的格式为0_1，1_1中的一项或多项；第一休眠小区组为针对激活时间外配置的，第一下行控制信息的格式为2_6。
可选地，实现方式一中，还可以满足以下条件：
所述第一休眠小区组为针对激活时间内配置的，在所述主小区上没有配置用于监测格式为0_1和/或1_1的第二下行控制信息的资源；这里是指所述主小区上没有配置用于监测格式为0_1和1_1两种格式中的任一种的第二下行控制信息的资源。或者，所述第一休眠小区组为针对激活时间外配置的，在所述主小区上没有配置用于监测格式为2_6的第二下行控制信息的资源。
通过上面的描述可知，当终端设备从第一小区接收到DCI format 2_6/0_1/1_1的DCI时，认为第一小区实际上不包含在第一休眠小区组内。如果所述第一辅小区休眠指示域指示所述第一休眠小区组为休眠状态，保持所述第一小区为非休眠状态。也就是无论是否在第一小区收到的休眠指示信息，第一小区始终保持非休眠状态。
当终端设备从主小区接收DCI format 2_6/0_1/1_1的DCI时，认为第一小区实际包含在第一休眠小区组内。也就在主小区收到的休眠指示信息后，可能会将第一小区从休眠状态切换为非休眠状态，或者将第一小区从非休眠状态切换为休眠状态。
实现方式二：
终端设备在主小区中接收来自网络设备的包括第二辅小区休眠指示域的第二下行控制信息，将所述第一休眠小区组中的辅小区，设置为所述第二辅小区休眠指示域指示的休眠状态或者非休眠状态。
其中，如果所述第二辅小区休眠指示域指示所述第一休眠小区组为休眠状态，则将所述第一休眠小区组中的辅小区设置为休眠状态；如果所述第二辅小区休眠指示域指示所述第一休眠小区组为非休眠状态，则将所述第一休眠小区组中的辅小区设置为非休眠状态。
其中，如果所述第一休眠小区组为针对激活时间内配置的，第二下行控制信息的格式为0_1，1_1中的一项或多项；第一休眠小区组为针对激活时间外配置的，第二下行控制信息的格式为2_6。
实现方式一和二，可以保证通过主小区把第一小区置成休眠状态，第一小区不能把第一小区自己置成休眠状态。
实现方式三：
终端设备在第一小区中接收来自网络设备的第一下行控制信息；所述第一下行控制信息包括第一辅小区休眠指示域。
一种情况，所述第一休眠小区组是为针对激活时间内配置的，在所述主小区上没有配置用于监测格式为0_1和/或1_1的第二下行控制信息的资源时，即主小区上既没有配置用于监测格式为0_1的第二下行控制信息的资源，也没有配置用于监测格式为1_1的第二下行控制信息的资源，或者，所述第一休眠小区组是为针对激活时间外配置的，在所述主小区上没有配置用于监测格式为2_6的第二下行控制信息的资源时，将所述第一休眠小区组中除了所述第一小区之外的辅小区，设置为所述第一辅小区休眠指示域指示的休眠状态或者非休眠状态；且如果所述第一辅小区休眠指示域指示所述第一休眠小区组为休眠状态，保持所述第一小区为非休眠状态；
另一种情况，所述第一休眠小区组是为针对激活时间内配置的，在所述主小区上配置了用于监测格式为0_1和/或1_1的第二下行控制信息的资源时，即主小区上配置用于监测格式为0_1的第二下行控制信息的资源和用于监测格式为1_1的第二下行控制信息的资源中的至少一种；或者所述第一休眠小区组是为针对激活时间外配置的，在所述主小区上配置了用于监测格式为2_6的第二下行控制信息的资源时，将所述第一休眠小区组中的辅小区，设置为所述第一辅小区休眠指示域指示的休眠状态或者非休眠状态。

终端设备可以将所述至少一个辅小区，设置为所述第二辅小区休眠指示信息指示的休眠状态或者非休眠状态。
可选地，在实现方式一或实现方式二中，终端设备工作在激活时间内，且在所述主小区上没有配置用于监测格式为0_1和/或1_1的第二下行控制信息的资源，这里可以是指所述主小区上没有配置用于监测格式为0_1和1_1两种格式中的任一种的第二下行控制信息的资源；或者，终端设备工作在激活时间外，且在所述主小区上没有配置用于监测格式为2_6的第二下行控制信息的资源。
实现方式三：
终端设备在第一小区中接收来自网络设备的第一下行控制信息；所述第一下行控制信息包括第一辅小区休眠指示信息；
一种情况中，如果终端设备工作在激活时间内，且在所述主小区上没有配置用于监测格式为0_1和1_1的第二下行控制信息的资源，即主小区上既没有配置用于监测格式为0_1的第二下行控制信息的资源，也没有配置用于监测格式为1_1的第二下行控制信息的资源；或者，终端设备工作在激活时间外，且在所述主小区上没有配置用于监测格式为2_6的第二下行控制信息的资源，终端设备可以将第一辅小区休眠指示信息指示的至少一个辅小区中，除了所述第一小区之外的辅小区，设置为所述第一辅小区休眠指示信息指示的休眠状态或者非休眠状态。
可选地，所述第一辅小区休眠指示信息可以不指示所述第一小区的休眠状态或者非休眠状态；或者，如果所述第一辅小区休眠指示信息指示所述第一小区为休眠状态，保持所述第一小区为非休眠状态。
另一种情况中，如果终端设备工作在激活时间内，且在所述主小区上配置了用于监测格式为0_1和/或1_1的第二下行控制信息的资源时，即主小区上配置用于监测格式为0_1的第二下行控制信息的资源和用于监测格式为1_1的第二下行控制信息的资源中的至少一种；或者，终端设备工作在激活时间外，且在所述主小区上配置了用于监测格式为2_6的第二下行控制信息的资源时；所述第一辅小区休眠指示信息指示所述第一小区的休眠状态 或者非休眠状态，终端设备可以将所述第一小区，设置为所述第一辅小区休眠指示域指示的休眠状态或者非休眠状态。
实施例五：
现有技术中，辅小区休眠指示域只能在主载波上发送，且用DCI format 0_1或DCI format 1_1指示辅载波休眠时，只在DCI不包含载波指示域，或者载波指示域为0时，辅小区休眠指示域才有效。本申请实施例中，辅小区休眠指示域是否有效，也存在多种情况，下面分别进行描述。
步骤一：网络设备在第一小区中向终端设备发送第一下行控制信息；
第一下行控制信息的格式可以为0_1，1_1以及2_6中的一项或多项。第一下行控制信息可以包括辅小区休眠指示信息，辅小区休眠指示信息用于指示辅小区为休眠状态或者非休眠状态。
一种可能的实现方式中，辅小区休眠指示信息可以包括至少一个比特，每一个比特对应一个休眠小区组，每个比特可以指示一个休眠小区组为休眠状态或非休眠状态。例如当辅小区休眠指示信息中的一个比特的取值为0，指示该比特对应的休眠小区组里的每一个辅小区为休眠状态；如果该比特对应的休眠小区组里的任一个辅小区中，终端设备工作在该辅小区的非休眠BWP中，则终端设备切换到该辅小区的休眠BWP中。当辅小区休眠指示信息中的一个比特的取值为1，指示该比特对应的休眠小区组里的每一个辅小区为非休眠状态；如果该比特对应的休眠小区组里的任一个辅小区中，终端设备工作在该辅小区的非休眠BWP中，那么终端设备继续工作在该非休眠BWP上，如果终端设备工作在该辅小区的休眠BWP中，那么终端设备切换到该辅小区的第一非休眠(first non-dormant)BWP。
在该实现方式中，辅小区休眠指示信息可以位于第一下行控制信息的辅小区休眠指示域中携带。
需说明的是，网络设备可以配置至少一个休眠小区组，所述至少一个休眠小区组中的小区为一个小区组中的辅小区，所述至少一个休眠小区组中的小区被配置了休眠下行BWP；该小区组可以为主小区组，也可以为辅小区组；该小区组中包括主小区和至少一个辅小区。
所述至少一个休眠小区组可以是网络设备针对active time内配置的，也可以是网络设备针对active time外配置的。第一小区可以位于其中一个休眠小区组，也可以不位于任一个休眠小区组，具体根据实际情况确定。
另一种实现方式中，辅小区休眠指示信息可以包括至少一个比特，每一个比特对应一个辅小区，每个比特可以指示一个辅小区为休眠状态或非休眠状态。例如当辅小区休眠指示信息中的一个比特的取值为0，指示该比特对应的辅小区为休眠状态；当辅小区休眠指示信息中的一个比特的取值为1，指示该比特对应的辅小区为非休眠状态。
在该实现方式中，辅小区休眠指示信息可以位于第一下行控制信息的特定域中携带，该特定域可以根据实际情况确定，例如该特定域可以为第一下行控制信息中的原来用于传输传输块1的调制编码方式的比特、原来用于传输传输块1的新数据指示的比特、冗余比特等。
本申请实施例中，第一下行控制信息还可以包括载波指示域(carrier indicator field，CIF)，载波指示域用于指示第一下行控制信息调度的小区(载波)，具体的，载波指示域可以用于指示其调度的物理下行共享信道(physical downlink shared channel，PDSCH)所属的小 区。例如，当载波指示域为0时，第一下行控制信息用来调度第一小区中的PDSCH；当载波指示域为1时，第一下行控制信息用来调度主小区中的PDSCH。
步骤二：终端设备在第一小区中接收来自网络设备的第一下行控制信息。
其中，所述第一小区为所述小区组中调度主小区的辅小区，具体的，可以通过第一小区发送下行控制信息来调度所述小区组中的主小区的数据传输。所述小区组为主小区组或辅小区组。
本申请实施例中，可以根据第一下行控制信息中的载波指示域所指示的载波，确定第一下行控制信息中的小区休眠指示信息是否有效，下面分不同情况进行描述。
情况1：第一下行控制信息包括辅小区休眠指示信息；当所述第一下行控制信息中的载波指示域指示所述第一小区或者所述主小区时，确定所述辅小区休眠指示信息有效。
本申请实施例中，辅小区休眠指示信息有效，可以是指终端设备将辅小区休眠指示信息指示的辅小区，设置为辅小区休眠指示信息指示的休眠状态或者非休眠状态。辅小区休眠指示信息无效，可以是指终端设备将忽略该辅小区休眠指示信息，视为未接收到辅小区休眠指示信息。
综上可知，情况1中，在第一小区中可以用第一下行控制信息调度主小区时，在载波指示域指示第一小区自己或者指示主小区时，第一下行控制信息中的辅小区休眠指示域有效。例如，第一下行控制信息中的辅小区休眠指示信息指示辅小区休眠时，终端设备将该辅小区设置为休眠状态。
情况2：第一下行控制信息包括辅小区休眠指示信息，如果只有第一小区中能够调度主小区，当所述第一下行控制信息中的载波指示域指示所述第一小区或者所述主小区时，确定所述辅小区休眠指示信息有效。
其中，只有第一小区中能够调度主小区，可以是指主小区上没有配置USS，而第一小区上配置了USS；或者，可以是指在所述主小区上没有配置用于监测格式为0_1和/或1_1的下行控制信息的资源，而第一小区上配置了用于监测格式为0_1和/或1_1的下行控制信息的资源；或者，可以是指在所述主小区上不监测格式为0_1和/或1_1的下行控制信息，而在第一小区上监测格式为0_1和/或1_1的下行控制信息；或者，可以是指在所述主小区上不监测包含所述辅小区休眠指示信息的下行控制信息，而在第一小区上监测包含所述辅小区休眠指示信息的下行控制信息。
情况3：如果第一下行控制信息包括辅小区休眠指示信息，第一小区不位于任何一个休眠小区组内，所述休眠小区组是网络设备在激活时间内配置的；当所述第一下行控制信息中的载波指示域指示所述第一小区或者所述主小区时，确定所述辅小区休眠指示信息有效。
如果第一下行控制信息包括辅小区休眠指示信息，所述第一小区位于一个休眠小区组内，当所述第一下行控制信息中的载波指示域指示所述主小区时，确定所述辅小区休眠指示信息有效；当所述第一下行控制信息中的载波指示域指示所述第一小区时，确定所述辅小区休眠指示信息无效。
情况4：第一下行控制信息包括辅小区休眠指示信息，如果终端设备还可以在主小区监测或接收格式为0_1和/或1_1的第二下行控制信息，当所述第一下行控制信息中的载波指示域指示所述主小区时，确定所述辅小区休眠指示信息有效；当所述第一下行控制信息中的载波指示域指示所述第一小区时，确定所述辅小区休眠指示信息无效。
情况5：第一下行控制信息包括辅小区休眠指示信息，如果终端设备还可以在主小区监测或接收格式为0_1和/或1_1的第二下行控制信息，当所述第一下行控制信息中的载波指示域指示第一小区或主小区时，确定所述辅小区休眠指示信息有效。
情况6：第一下行控制信息包括辅小区休眠指示信息，如果第一下行控制信息不能用于调度数据传输，且第一下行控制信息的格式为1_1，当所述第一下行控制信息中的载波指示域指示第一小区或主小区时，确定所述辅小区休眠指示信息有效。
可选地，情况1至情况5中，辅小区休眠指示信息可以包括至少一个比特，每一个比特可以指示一个休眠小区组为休眠状态或非休眠状态。情况6中，辅小区休眠指示信息可以包括至少一个比特，每一个比特可以指示一个辅小区为休眠状态或非休眠状态。
