4)在该上行载波配置了物理上行链路控制信道(physical uplink control channel，PUCCH)上的情况下，在该PUCCH上可以发送上行控制信息，即在该上行载波上可以进行PUCCH传输。
当上行载波的载波状态为去激活态时，上行载波是去激活的，终端设备在该上行载波上不支持上行通信。具体的，终端设备在处于去激活态的上行载波上的行为包括：
1)不在该上行载波上发送上行参考信号，比如SRS、DMRS、PTRS或者PRACH上承载的信号。
2)不在该上行载波上进行CSI的上报。
3)不在该上行载波上通过PUSCH进行数据传输，即不在该上行载波上进行PUSCH传输。
4)不在该上行载波上通过PUCCH进行信息传输，即在该上行载波上不进行PUCCH传输。需要说明的是，在载波状态为去激活态的情况下，即使在该上行载波上配置了PUCCH，也不在该上行载波上进行PUCCH传输。
当上行载波的载波状态为第二状态时，上行载波是激活的，且终端设备在该上行载波上不支持上行通信。示例的，当上行载波的载波状态为第二状态时，上行载波上没有激活的BWP，但与该上行载波属于同一小区的下行载波上有激活的BWP；或者，当上行载波的载波状态为第二状态时，上行载波上激活的BWP为预配置的BWP，所述预配置的BWP可以是通过协议定义的，也可以是网络设备通过RRC信令配置给终端设备的，对此不作限定。或者，当上行载波的载波状态为第二状态时，上行载波上有激活的BWP，但终端设备在上行载波上激活的BWP的端口数或通道数为0。或者，当上行载波的载波状态为第二状态时，上行载波上有激活的BWP，但该上行载波对应的载波状态标识用于指示上行载波状态为第二状态。所述端口包括上行天线端口，所述通道为上行发送通道。示例的，当上行载波的载波状态为第二状态时，终端设备在该上行载波上的行为包括：
1)不在该上行载波上发送上行参考信号，比如SRS、DMRS、PTRS或者PRACH上承载的信号。
2)不在该上行载波上进行CSI的上报。
3)不在该上行载波上通过PUSCH进行数据传输，即不在该上行载波上进行PUSCH传输。
4)不在该上行载波上通过PUCCH进行信息传输，即在该上行载波上不进行PUCCH传输。
可以理解的是，针对同一载波可以在不同载波状态间切换。以上行载波为例，示例的，如图1B所示，为针对同一上行载波的载波状态之间的切换示意图。例如，网络设备可以通过下行控制信息(downlink control information，DCI)指示终端设备将上行载波的载波状态从激活态切换到第二状态、或者从第二状态切换到激活态。具体的，DCI可以通过指 示上行载波的端口数或通道数，向终端设备指示为其配置的上行载波的载波状态是从激活态切换到第二状态、还是从第二状态切换到激活态。在一种实现方式中，DCI可以通过指示上行载波的端口数或通道数为0，向终端设备指示为其配置的上行载波的载波状态从激活态切换到第二状态。在另一种实现方式中，DCI可以通过指示上行载波的端口数或通道数为N，向终端设备指示为其配置的上行载波的载波状态从第二状态切换到激活态，所述N为大于0的整数。需要说明的是，在终端设备配置有多个服务小区的情况下，网络设备还可以通过DCI向终端设备指示为终端设备配置的多个服务小区的上行载波的载波状态。又例如，网络设备可以通过媒体接入控制控制单元(media access control control element，MAC CE)信令指示终端设备将为其配置的上行载波的载波状态从激活态切换到去激活态、或者从去激活态切换到激活态、或者从去激活态切换到第二状态、或者从第二状态切换到去激活态。
或者，在另一些实施例中，网络设备可以通过半静态方式指示终端设备进行载波状态的切换。示例的，网络设备可以针对一个上行载波通过高层信令配置一个或多个时间图样，时间图样内包括了与上行载波的载波状态对应的时间单元。比如，时间图样包括10个时间单元，前7个时间单元对应的上行载波的载波状态为激活态，后3个时间单元对应的上行载波的载波状态为第二状态。在这种情况下，终端设备针对上行载波，可以根据时间图样将上行载波的载波状态配置为激活态，并在前7个时间单元上可以通过上行载波进行上行通信，在后3个时间单元上将上行载波的载波状态从激活态切换到第二状态。或者，时间图样内包括与上行载波的载波状态为激活态时对应的时间单元，而时间图样内未与上行载波的载波状态对应的时间单元，可以由网络设备自适应确定为激活态或第二状态。例如，时间图样包括10个时间单元，前7个时间单元对应的上行载波的载波状态为激活态，后3个时间单元对应的上行载波的载波状态取决于网络设备的实现。
进一步的，在一些实施例中，在网络设备通过高层信令为终端设备配置了多个时间图样的情况下，网络设备还可以通过物理层信令或MAC CE信令激活其中一个时间图样，终端设备可以根据激活的时间图样，确定对应的上行载波的载波状态。
此外，网络设备也可以针对所有的激活上行载波或配置的上行载波统一配置一个或多个时间图样用于指示不同上行载波在时域上的载波状态。比如终端设备配有2个上行载波，分别为载波1和载波2，网络设备针对载波1和载波2统一配置的时间图样如图1A所示，包括10个时隙。其中，时隙0-3对应的载波1的载波状态为激活态、载波2的载波状态为第二状态；时隙4-6对应的载波1的载波状态为第二状态、载波2的载波状态为激活态；时隙7-9对应的载波1和载波2的载波状态均为激活态。在这种情况下，终端设备根据载波1和载波2对应的时间图样，在时隙0-3上将载波1的载波状态配置为激活态、将载波2的载波状态配置为第二状态，在时隙4-6上将载波1的载波状态配置为第二状态、将载波2的载波状态配置为激活态，在时隙7-9上将载波1的载波状态配置为激活态、继续保持载波2的载波状态为激活态的配置。
进一步的，在一些实施例中，网络设备可以针对上行载波配置具有周期性的时间图样。以某一上行载波的时间图样为例，终端设备针对该上行载波，可以根据周期性的时间图样，确定该上行载波的载波状态。例如，周期性时间图样的周期为10个时间单元，其中前7个时间单元对应的上行载波的载波状态为激活态，后3个时间单元对应的上行载波的载波状态为第二状态的情况下，终端设备可以每隔3个时间单元将上行载波的载波状态从第二 状态切到激活态，每隔7个时间单元将上行载波的载波状态从激活态切换到第二状态。比如，将上行载波的载波状态从第二状态切到激活态的周期可以和传输SRS的周期相同。
在终端设备的多个服务小区的上行载波的时间图样有冲突的情况下，比如在同一个时间单元，终端设备的N个服务小区中M个服务小区需要进入激活态，或M个服务小区需要发送上行信号，而终端设备最多只能满足L个服务小区同时发送上行信号，其中N大于或等于M，M大于或等于L，且N、M和L为正整数。终端设备可以根据M个服务小区的优先级来确定能够进行上行发送的服务小区。其中，服务小区的优先级可以预定义，比如M个服务小区中Pcell优先级高于SPcell优先级，SPCell的优先级高于Scell的优先级。对于多个Scell来说，网络设备和/或终端设备可以根据有传输需求的信道来确定辅小区的优先级。例如，辅小区的优先级按照从高到低的顺序依次为：PRACH、承载HARQ-ACK信息和/或SR的PUCCH/PUSCH、承载CSI的PUCCH/PUSCH、不承载HARQ-ACK信息/CSI的PUSCH、承载SRS的信道。另外，对于不同辅小区来说，如果信道相同，则根据信道上承载数据的周期，确定辅小区的优先级。例如，辅小区的优先级按照从高到低的顺序依次为：非周期、半永久、周期。此外，在一些实施例中，在某一服务小区包括上行载波和增补上行载波的情况下，上行载波的优先级高于增补上行载波的优先级。
或者，在又一些实施例中，网络设备可以根据上行的数据调度来隐式的指示一个上行载波的状态切换。比如在同一个时间单元，网络设备调度了终端设备在上行载波1上使用1端口(port)发送PUSCH，在上行载波2上使用1port发送PUSCH，那么上行载波1和上行载波2为激活态，其他激活的上行载波为第二状态。
8、服务小区状态。本申请实施例中服务小区状态指的是服务小区的小区状态，可以包括激活态、去激活态、休眠态和第一状态。其中，第一状态可以简称为第一态。需要说明的是，本申请实施例中第一状态也可以称之为X状态、或者其它状态等，是除激活态、去激活态、休眠态以外的一种小区状态，或者是一种添加了额外限制的激活态，本申请实施例对第一状态的名称不作限定。
当服务小区状态为激活态时，在服务小区配置有上行载波和下行载波的情况下，服务小区的上行载波支持上行通信，服务小区的下行载波支持下行通信。换句话说，在服务小区状态为激活态的情况下，终端设备能够在上行载波和下行载波上进行通信。示例的，在服务小区状态为激活态的情况下，终端设备能够在上行载波上进行通信，可以理解为上行载波是激活的；终端设备能够在下行载波上进行通信，可以理解为下行载波是激活的。又示例的，在服务小区状态为激活态的情况下，服务小区的上行载波的载波状态为激活态，且服务小区的下行载波的载波状态为激活态。
具体的，在服务小区状态为激活态的情况下，终端设备在服务小区上的行为可以包括：
1)在该服务小区上可以发送上行参考信号，比如SRS、DMRS、PTRS、或者PRACH上承载的信号。
2)在该服务小区上可以进行CSI上报，即针对该服务小区的CSI进行上报；
3)在该服务小区上可以监听物理下行链路控制信道(physical downlink control channel，PDCCH)，即可以监听该服务小区的PDCCH。
4)可以监听针对该服务小区的PDCCH，比如跨载波调度、休眠状态指示等。
5)在该服务小区的物理上行链路共享信道(physical uplink shared channel，PUSCH)上可以发送数据，即在该服务小区上可以进行PUSCH传输。
6)在该服务小区配置了物理上行链路控制信道(physical uplink control channel，PUCCH)上的情况下，在该PUCCH上可以发送上行控制信息，即在该服务小区上可以进行PUCCH传输。
7)在该服务小区的物理下行链路共享信道(physical downlink shared channel，PDSCH)上接收数据，即在该服务小区可以进行PDSCH的传输。
8)在该服务小区上可以接收下行参考信号，例如CSI-RS、DMRS、PTRS、TRS或同步信号块(synchronization signal block，SSB)等。
当服务小区状态为去激活态时，服务小区的上行载波不支持上行通信，服务小区的下行载波不支持下行通信。换句话说，在服务小区状态为去激活态的情况下，终端设备不能在上行载波和下行载波上进行通信。示例的，在服务小区状态为去激活态的情况下，终端设备不能在上行载波上进行通信，可以理解为所有上行载波是去激活的；终端设备不能在下行载波上进行通信，可以理解为下行载波是去激活的。又示例的，在服务小区状态为去激活态的情况下，服务小区的上行载波的载波状态为去激活态，服务小区的下行载波为去激活态。
具体的，在服务小区状态为去激活态的情况下，终端设备在服务小区上的行为可以包括：
1)不在该服务小区上可以上行参考信号，比如SRS、DMRS、PTRS、或者PRACH上承载的信号。
2)不在该服务小区上进行CSI上报，即针对该服务小区的CSI不进行上报；
3)不在该服务小区上可以监听PDCCH，即不监听该服务小区的PDCCH；
4)不监听针对该服务小区的PDCCH，比如跨载波调度、休眠状态指示等；
5)不在该服务小区的PUSCH上发送数据，即在该服务小区上不进行PUSCH传输；

8)不在该服务小区上接收下行参考信号，例如CSI-RS、DMRS、PTRS、TRS或同步信号块(synchronization signal block，SSB)等。
当服务小区状态为休眠态时，服务小区的上行载波不支持上行通信，服务小区的下行载波可以支持部分下行通信。终端设备在服务小区处于休眠态时在服务小区上的行为包括：
1)在该服务小区上可以进行CSI测量，即针对在该服务小区发送的CSI-RS进行测量；
2)不在该服务小区上发送上行参考信号，比如SRS、DMRS、PTRS或者PRACH上承载的信号；
3)不在该服务小区上进行CSI的上报；
4)不在该服务小区上通过PUSCH进行数据传输，即不在该服务小区上进行PUSC传输；
5)不在该服务小区上通过PUCCH进行上行控制信息传输，即在该服务小区上不进行PUCCH传输；
6)不在该服务小区上监听物理下行链路控制信道(physical downlink control channel，PDCCH)，即不可以监听该服务小区的PDCCH；
7)可以监听针对该服务小区的PDCCH，比如休眠指示。
当服务小区状态为第一状态时，服务小区的下行载波支持下行通信，服务小区的上行 载波不支持上行通信。换句话说，在服务小区状态为第一状态的情况下，终端设备可以在下行载波上进行通信，但不能在上行载波上进行通信。
示例的，在服务小区状态为第一状态的情况下，服务小区的下行载波是激活的，服务小区的上行载波是去激活的。例如，在服务小区状态为第一状态的情况下，服务小区的上行载波的载波状态为去激活态，服务小区的下行载波的载波状态为激活态。
又示例的，在服务小区状态为第一状态的情况下，服务小区的下行载波是激活的，服务小区的上行载波是激活的，但该上行载波的端口数和/或通道数为0。
又示例的，在服务小区状态为第一状态的情况下，服务小区的下行载波是激活的，服务小区的上行载波是激活的，但该上行载波上激活的BWP为预配置的BWP、或者下行载波上激活的BWP为预配置的BWP。
又示例的，在服务小区状态为第一状态的情况下，服务小区的下行载波是激活的，服务小区的上行载波是激活的，但是网络设备针对服务小区状态为第一状态的小区配置的小区状态标识不同于网络设备针对小区状态为激活态的小区配置的小区状态标识。例如，网络设备针对服务小区状态为第一状态的服务小区配置的小区状态标识为第一小区状态标识(比如1)，网络设备针对服务小区状态为激活态的服务小区配置的小区状态标识为第二小区状态标识(比如0)。
特别的，在终端设备的一个服务小区中包括或配置有多个上行载波的情况下，如果多个上行载波有至少一个上行载波可以进行上行通信，那么该终端设备的服务小区状态为激活态。
又示例的，在服务小区状态为第一状态的情况下，服务小区的下行载波的载波状态为激活态，服务小区的上行载波状态为第二状态，关于上行载波的载波状态为第二状态可以参见上述关于载波状态中第二状态的相关说明，在此不再赘述。
在一些实施例中，在服务小区状态为第一状态的情况下，终端设备在服务小区上的行为可以包括：
1)在该服务小区上进行CSI测量，即针对在该服务小区发送的CSI-RS进行测量；
2)在该服务小区上监听PDCCH，即可以监听该服务小区的PDCCH。

4)在该服务小区的PDSCH上接收数据，即在该服务小区上接收PDSCH。
5)在该服务小区上接收下行参考信号，比如CSI-RS、DMRS、PTRS、TRS、SSB等。
6)不在该服务小区上发送承载在PRACH、PUCCH、PUSCH上的信号、上行DMRS、SRS或者上行PTRS。
需要说明的是，选项1)、4)、5)、6)是可选的，选项2)、3)中一项或多项为必选项。
本申请实施例中针对同一服务小区可以在不同服务小区状态之间切换。例如，终端设备可以根据网络设备发送的服务小区状态切换指示进行服务小区状态切换，示例的，如图2所示。在一种实现方式中，终端设备根据第一指示，将服务小区状态从去激活态切换到第一状态。可以理解的是，激活态、去激活态和休眠态之间的切换可以参见现有技术中的相关描述，在此不再赘述。针对休眠态和第一状态之间的切换，比如终端设备将服务小区状态在休眠态与第一状态之间进行切换可以通过下列方式实现：将载波状态先从休眠态切换到激活态，然后再从激活态切换到第一状态；再比如终端设备将服务小区状态从第一状 态切换到休眠态，可以通过DCI来触发，实现方法与将服务小区状态从激活态到休眠态类似。本申请实施例中重点描述激活态和第一状态之间的切换，以及去激活态和第一状态之间的切换。
本申请实施例可以应用于LTE、NR等通信系统中。如图3所示，为本申请实施例的一种通信系统的网络架构示意图，包括终端设备和网络设备。其中，本申请实施例的网络设备和终端设备可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在空中的飞机、气球和人造卫星上等。本申请实施例对网络设备和终端设备的部署场景不做限定。
需要说明的是，本申请实施例中网络设备和终端设备之间以及终端设备和终端设备之间可以通过授权频谱(licensed spectrum)进行通信，也可以通过免授权频谱(unlicensed spectrum)进行通信，也可以同时通过授权频谱和免授权频谱进行通信，对此不做限定。网络设备和终端设备之间以及终端设备和终端设备之间可以通过6千兆赫兹(gigahertz，GHz)以下的频谱进行通信，也可以通过6GHz以上的频谱进行通信，还可以同时使用6GHz以下的频谱和6GHz以上的频谱进行通信。即本申请实施例既适用于低频场景(例如sub6G)，也适用于高频场景(6G以上)。本申请实施例还可以应用于终端设备配置有多个服务小区或载波的场景，例如CA场景、双连接(dual connection，DC)场景和SUL场景、CA和SUL组合场景等。
图3所示的通信系统的网络架构，仅为一个举例，并不对本申请实施例中的通信系统的网络架构构成限定。本申请实施例不限定通信系统中网络设备的个数、终端设备的个数。示例的，当本申请实施例的通信系统中包括多个网络设备时，网络设备与网络设备之间可以进行多点协同通信。例如，通信系统中包括多个宏基站、多个微基站，其中宏基站与宏基站、微基站与微基站、宏基站与微基站间可以进行多点协同通信。
下面结合附图，对本申请实施例的方法进行详细的介绍。
示例的，如图4所示，为本申请实施例的一种小区状态切换方法的流程图，具体包括以下步骤：
401、网络设备向终端设备发送第一指令。第一指令用于指示将终端设备的服务小区状态切换至第一状态或者切换出第一状态。其中，服务小区状态为第一状态时，服务小区的下行载波支持下行通信，服务小区的上行载波不支持上行通信，具体可以参见上述关于服务小区状态的相关描述，在此不再赘述。
在一些实施例中，网络设备可以向终端设备发送第一指令，比如可以周期性和/或通过事件触发来发送所述第一指令。示例的，网络设备可以针对终端设备配置N个服务小区，如果激活N个服务小区后，终端设备上行通信支持的最大端口数和/或通道数难以满足N个服务小区的上行载波的同时传输需求，可以将N个服务小区中的M个服务小区初始化为服务小区状态为激活态的服务小区，将剩余的N-M个服务小区初始化为服务小区状态为第一状态的服务小区。然后，根据N个服务小区的传输需求，将服务小区中M个服务小区的小区状态切换至第一状态，和/或者将服务小区中N-M个服务小区的小区状态切换出第一状态。需要说明的是，网络设备针对终端设备配置的服务小区的个数N、以及针对终端设备激活的服务小区的个数M不超过终端设备支持的最大能力，且N≥M＞0。
例如，网络设备可以根据N个服务小区的优先级顺序，初始化配置N个服务小区的小区状态，以及进行小区状态的切换。
示例的，第一指令可以携带在DCI或MAC CE信令中由网络设备发送给终端设备，可以是小区级的信令，也可以是终端设备特定的信令，或者终端组集的信令，对此不作限定。第一指令中指示进入第一状态或切出第一状态的对象可以是一个小区或载波，也可以是一个小区组或载波组。
402、终端设备接收来自网络设备的第一指令，根据第一指令切换服务小区状态。
以下结合第一状态对本申请实施例的小区状态切换方法进行具体介绍。
实施例一、当服务小区状态为第一状态时，服务小区的上行载波是去激活的，服务小区的下行载波是激活的。
在这种情况下，在一些实施例中，第一指令可以为载波的激活或去激活信令。例如，当终端设备的服务小区状态为激活态时，如果接收到来自网络设备发送的第一指令，第一指令用于指示去激活上行载波，则终端设备根据第一指令，去激活服务小区的上行载波。从而将服务小区状态从激活态切换到第一状态。在此种情况下，第一指令不用于指示下行载波的状态切换，即下行载波状态保持不变。再例如，当服务小区状态为第一状态时，终端设备如果接收到来自网络设备发送的第一指令，第一指令用于指示激活上行载波，则终端设备根据第一指令，激活服务小区的上行载波。从而将服务小区状态从第一状态切换到激活态。在此种情况下，第一指令不用于指示下行载波的状态，即下行载波状态保持不变。又例如，当服务小区状态为第一状态时，终端设备如果接收到来自网络设备发送的第一指令，第一指令用于指示去激活下行载波，则终端设备根据第一指令，去激活服务小区的下行载波。在此种情况下，第一指令不用于指示上行载波的状态切换，即上行载波状态保持不变。从而将服务小区状态从第一状态切换到去激活态。又例如，终端设备当服务小区状态为去激活态时，如果接收到来自网络设备发送的第一指令，第一指令用于指示激活下行载波，则终端设备根据第一指令，激活服务小区的下行载波，从而将服务小区状态从去激活态切换第一状态。在此种情况下，第一指令不用于指示上行载波的状态切换，即上行载波状态保持不变。在一种情况中，例如，第一指令用于激活服务小区中的一个上行载波；再例如，第一指令用于激活服务小区中的一个下行载波。在另一种情况中，如果服务小区包含多个上行载波或者下行载波，例如，第一指令用于激活服务小区中的所有上行载波；再例如，第一指令用于激活服务小区中的所有下行载波。通过该种方式，可以灵活实现上下行载波的独立激活、去激活，分别匹配上下行不同的终端能力和信道、剩余资源情况。
上述以载波激活、去激活举例，对于服务小区激活、去激活类似。第一指令可以为服务小区的激活或去激活信令。例如，当终端设备接收到来自网络设备发送的第一指令，第一指令用于指示去激活上行服务小区1，则终端设备根据第一指令，去激活上行服务小区1。在此种情况下，第一指令不用于指示下行服务小区的状态切换，即下行服务小区状态保持不变。再例如，终端设备如果接收到来自网络设备发送的第一指令，第一指令用于指示激活上行服务小区1，则终端设备根据第一指令，激活上行服务小区1。在此种情况下，第一指令不用于指示下行服务小区的状态切换，即下行服务小区状态保持不变。又例如，当终端设备接收到来自网络设备发送的第一指令，第一指令用于指示去激活下行服务小区1，则终端设备根据第一指令，去激活下行服务小区1。在此种情况下，第一指令不用于指示上行服务小区的状态切换，即上行服务小区状态保持不变。再例如，终端设备如果接收到来自网络设备发送的第一指令，第一指令用于指示激活下行服务小区1，则终端设备根据第一指令，激活下行服务小区1。在此种情况下，第一指令不用于指示上行服务小区的 状态切换，即上行服务小区状态保持不变。在一种情况中，例如，第一指令用于激活上行服务小区中的一个上行载波；再例如，第一指令用于激活上行服务小区中的一个下行载波。在另一种情况中，如果上行服务小区包含多个上行载波或者下行服务小区包含多个下行载波，例如，第一指令用于激活上行服务小区中的所有上行载波；再例如，第一指令用于激活下行服务小区中的所有下行载波。通过该种方式，可以灵活实现上下行服务小区的独立激活、去激活，分别匹配上下行不同的终端能力和信道、剩余资源情况。
需要说明的是，在终端设备配置有N个服务小区的情况下，网络设备针对终端设备配置的多个服务小区的载波的激活或去激活信令可以通过RRC信令或DCI或MAC CE信令指示给终端设备。所述RRC信令或DCI或MAC CE信令可以在任意一个激活的下行载波上发送给终端设备，激活的下行载波可以是PCel、SCell或PSCell的下行载波，此处不做限定。
在另一些实施例中，第一指令还可以为小区级信令。在这种情况下，第一指令中的至少一个比特用于指示终端设备的当前的服务小区状态、且第一指令中的至少一个比特用于指示终端设备需要切换到的服务小区状态。例如，当终端设备的当前的服务小区状态为激活态时，如果接收到来自网络设备发送的第一指令，其中第一指令为小区状态从激活态切换到第一状态的使能信令，则终端设备根据第一指令，将服务小区状态从激活态切换到第一状态。再例如，终端设备当前的服务小区状态为第一状态时，如果接收到来自网络设备发送的第一指令，其中第一指令为小区状态激活信令，则终端设备根据第一指令，将服务小区状态从第一状态切换到激活态。又例如，终端设备当前的服务小区状态为去激活态时，如果接收到来自网络设备发送的第一指令，其中第一指令为小区状态从去激活态切换到第一状态的使能信令，则终端设备根据第一指令，将服务小区状态从去激活态切换到第一状态。又例如，终端设备当前的服务小区状态为第一状态时，如果接收到来自网络设备发送的第一指令，其中第一指令为小区状态去激活信令，则终端设备根据第一指令，将服务小区状态从第一状态切换到去激活态。
实施例二、当服务小区状态为第一状态时，服务小区的下行载波是激活的，服务小区的上行载波是激活的、但上行载波的端口数和/或通道数为0。以下以端口数为例，关于通道数可以参见端口数的相关介绍。
在这种情况下，例如，当终端设备的服务小区状态为激活态时，如果接收到来自网络设备发送的第一指令，第一指令用于指示服务小区的上行载波的端口数配置为0，则终端设备根据第一指令，将服务小区状态从激活态切换到第一状态。比如，第一指令用于指示服务小区的上行载波的端口数配置为0可以通过下列方式实现：在小区激活信令中携带服务小区的上行载波的端口数为0的指示。
再例如，当终端设备的服务小区状态为第一状态时，如果接收到来自网络设备发送的第一指令，第一指令用于指示服务小区的上行载波的端口数配置为P，0＜P≤M，且P为正整数，M为终端设备上行通信支持的最大端口数，则终端设备根据第一指令，将服务小区状态从第一状态切换到激活态。比如，第一指令用于指示服务小区的上行载波的端口数配置为P可以通过下列方式实现：在小区激活信令中携带服务小区的上行载波的端口数、或者在小区激活信令中携带服务小区的上行载波的端口数不为0的指示。可以理解的是，网络设备可以半静态或动态向终端设备发送携带服务小区的上行载波的端口数为P、或者在小区激活信令中携带服务小区的上行载波的端口数不为0的指示的小区激活信令。
又例如，当终端设备的服务小区状态为去激活态时，如果接收到来自网络设备发送的第一指令，第一指令用于指示将服务小区的上行载波的端口数配置为0，则终端设备根据第一指令，将服务小区状态从去激活态切换到第一状态。比如，第一指令用于指示服务小区的上行载波的端口数配置为0可以通过下列方式实现：在小区激活信令中携带服务小区的上行载波的端口数、或者在小区激活信令中携带服务小区的上行载波的端口数为0的指示。示例的，本申请实施例中的小区激活信令可以为RRC信令、MAC CE信令或DCI等，对此不作限定。
又例如，当终端设备的服务小区状态为第一状态时，如果接收到来自网络设备发送的第一指令，第一指令用于指示去激活服务小区，则终端设备根据第一指令，将服务小区状态从第一状态切换到去激活态。
实施例三、当服务小区状态为第一状态时，服务小区的下行载波是激活的，服务小区的上行载波是激活的、但上行载波上激活的BWP是预配置BWP；或者，当服务小区状态为第一状态时，服务小区的下行载波是激活的，服务小区的上行载波是激活的、但下行载波上激活的BWP是预配置的BWP。例如，在上行载波上激活的BWP为预配置的BWP的情况下，预配置的BWP的端口数和/或通道数为0。再例如，在下行载波上激活的BWP为预配置的BWP的情况下，上行载波的端口数和/或通道数为0。示例的，网络设备可以通过RRC信令向终端设备指示预配置的BWP。例如，RRC信令中包括预配置BWP的BWP ID。或者，服务小区的上行载波上的预配置BWP可以是通过协议预定义的。
以上行载波上激活的BWP为预配置的BWP为例。在这种情况下，例如，当终端设备的服务小区状态为激活态时，如果接收到来自网络设备发送的第一指令，第一指令用于指示激活服务小区的上行载波上预配置的BWP，则终端设备根据第一指令，将服务小区状态从激活态切换到第一状态。再例如，当终端设备的服务小区状态为第一状态时，如果接收到来自网络设备发送的第一指令，第一指令用于指示激活服务小区的上行载波上端口数为Q的BWP，0＜Q≤M，M为终端设备上行通信支持的最大端口数，则终端设备根据第一指令，将预配置的BWP切换为上行载波上端口数为Q的BWP(即上行载波上端口数不为0的BWP)，从而将服务小区状态从第一状态切换到激活态。需要说明的是，本申请实施例中关于BWP切换可以复用现有技术中的BWP切换机制，通过BWP ID进行切换，在此不再赘述。
示例的，网络设备可以动态或半静态向终端设备发送第一指令，进行BWP的切换，从而实现服务小区状态中激活态和第一状态之间的切换。
比如，在终端设备配置有多个服务小区的场景下，可以将多个服务小区的第一指令携带在一个信令中发送给终端设备，也可以每个服务小区的第一指令单独发送给终端设备。以终端设备配置的服务小区有小区1、小区2和小区3为例，小区1和小区3的服务小区状态为激活态、小区2的服务小区状态为第一状态，0用于指示激活服务小区的上行载波上预配置的BWP，1用于指示激活服务小区的上行载波上非预配置的BWP，如果终端设备接收到的信令为011，则终端设备将小区1的小区状态从激活态切换为第一状态，将小区2的小区状态从第一状态切换到激活态，小区3的小区状态保持激活态不变。
需要说明的是，针对实施例三中，服务小区状态中去激活态和第一状态之间的切换可以参见实施例二中的关于去激活态和第一状态之间切换的相关介绍，在此不再赘述。
实施例四、当服务小区状态为第一状态时，服务小区的下行载波是激活的，服务小区 的上行载波是激活的、但小区状态标识为第一小区状态标识，其中，第一小区状态标识用于标识第一状态。
在这种情况下，例如，终端设备当服务小区状态为激活态时，如果接收到来自网络设备发送的第一指令，第一指令用于指示服务小区的小区状态标识配置为第一小区状态标识，则终端设备根据第一指令，将服务小区状态从激活态切换到第一状态。再例如，终端设备当服务小区状态为去激活态时，如果接收到来自网络设备发送的第一指令，第一指令用于指示服务小区的小区状态标识配置为第一小区状态标识，则终端设备根据第一指令，将服务小区状态从去激活态切换到第一状态。再例如，终端设备当服务小区状态为第一状态时，如果接收到来自网络设备发送的第一指令，第一指令用于指示服务小区的小区状态标识配置为第二小区状态标识，则终端设备根据第一指令，将服务小区状态从第一状态切换到激活态。第二小区状态标识用于标识激活态。再例如，终端设备当服务小区状态为第一状态时，如果接收到来自网络设备发送的第一指令，第一指令用于指示服务小区的小区状态标识配置为第三小区状态标识，则终端设备根据第一指令，将服务小区状态从第一状态切换到去激活态。第三小区状态标识用于标识去激活态。在一种实现方式中，第一小区状态标识为11，第二小区状态标识为10，第三小区状态标识为01。
示例的，网络设备可以动态或半静态向终端设备发送第一指令，进行小区状态标识的配置。需要说明的是，在终端设备配置有多个服务小区的场景下，可以将多个服务小区的第一指令携带在一个信令中发送给终端设备，也可以每个服务小区的第一指令单独发送给终端设备。
实施例五、当服务小区状态为第一状态时，服务小区的下行载波的载波状态为激活态，服务小区的上行载波的载波状态为第二状态，第一指令的具体实现与上行载波的载波状态为第二状态时的具体实现有关，示例的，实施例五中关于服务小区状态的切换可以参见上述实施例一至实施例四中服务小区状态的切换的介绍，在此不再赘述。
需要说明的是，本申请实施例中上述关于服务小区状态为第一状态时终端设备的行为可以相互结合使用，也可以单独使用，对此不作限定。例如，将实施例三和实施例四相互结合，则第一指令可以用于指示载波上激活的BWP和小区状态标识。
还需要说明的是，上述五种关于服务小区状态为第一状态的介绍中，均涉及了下行载波，在服务小区不包括下行载波或服务小区未配置有下行载波的情况下，上述关于服务小区状态为第一状态的介绍中可以不包括涉及激活的下行载波的介绍。
在另一些实施例中，终端设备获取终端能力信息，终端设备向网络设备上报能力信息，该能力信息包括终端设备支持的频段、以及终端设备支持的频段上所支持的最大通道数和/或最大端口数和/或最大天线数，以便于网络设备针对为终端设备配置的服务小区的上行载波配置相应的通道数和/或端口数和/或天线数。进一步的，终端设备向网络设备上报的能力信息还可以包括终端设备上行通信支持的最大端口数和/或通道数和/或最大天线数。进一步的，终端设备向网络设备上报的能力信息还可以包括终端设备下行通信支持的最大端口数和/或通道数和/或最大天线数。
可选的，终端设备上报的能力包括以下至少一种：
1、可同时配置的band/CC组合、或者可同时配置的band/CC个数M、或者可同时配置的band/CC总带宽或带宽组合、或者可同时配置的服务小区组合；
2、可同时激活的band/CC组合、或者可同时激活的band/CC个数K、或者可同时激 活的band/CC总带宽或带宽组合、或者可同时激活的服务小区组合；
3、可同时或可并行传输的band/CC组合、或者可同时或可并行传输的band/CC个数m、或者可同时或可并行传输的band/CC总带宽或带宽组合、或者可同时或并行传输的服务小区组合；
4、可快速切换的band/CC组合、或者可快速切换的band/CC集合个数L、或者可快速切换的服务小区组合。
针对上述上报的能力，终端设备可以独立上报，能力之间是解耦的，即不同的能力是可以相同或不同的。针对一种能力，其对应的上行和下行也是解耦的，即可以只上报上行或下行中的一个，也可以都上报，上行和下行的能力也是可以相同或不同的。示例的，以上行载波能力为例，M≥K≥L≥m，即终端设备可配置的上行载波个数大于或者等于可以同时激活的上行载波个数，可以同时激活的上行载波个数大于或者等于可快速切换的上行载波个数，可快速切换的上行载波个数大于或者等于可同时传输的上行载波个数。基站可以通过RRC、MAC CE、DCI等信令指示用户进行快速载波切换；用户在可快速切换或可同时传输的上行band/CC/服务小区组合中的band/CC/服务小区上发送上行数据信道、上行控制信息、上行随机接入信道或上行参考信号，即PUSCH，PUCCH，PRACH，SRS，DMRS等。示例的，以上行能力为例，终端设备上报的可同时激活的上行band组合是可同时配置的上行band组合的子集/全集，和/或，终端设备上报的可同时传输的上行band组合是可同时激活的上行band组合的子集/全集。示例的，以上行能力为例，终端设备上报的可同时激活的上行band/CC总带宽小于等于可同时配置的上行band/CC总带宽，和/或，终端设备上报的可同时传输的上行band/CC总带宽小于等于可同时激活的上行band/CC总带宽。同理，对于下行载波能力，M≥K≥L≥m，即终端设备可配置的下行载波个数大于或者等于可以同时激活的下行载波个数，可以同时激活的下行载波个数大于或者等于可快速切换的下行载波个数，可快速切换的下行载波个数大于或者等于可同时传输的下行载波个数。基站可以通过RRC、MAC CE、DCI等信令指示用户进行快速载波切换；用户在可快速切换或可同时传输的下行band/CC/服务小区组合中的band/CC/服务小区上接收下行数据信道、下行控制信息、下行同步信道或者下行参考信号，即PDSCH，PDCCH，SSB，CSI-RS，DMRS等。示例的，以下行能力为例，终端设备上报的可同时激活的下行band组合是可同时配置的下行band组合的子集/全集，和/或，终端设备上报的可同时接收的下行band组合是可同时激活的下行band组合的子集/全集。示例的，以下行能力为例，终端设备上报的可同时激活的下行band/CC总带宽小于等于可同时配置的下行band/CC总带宽，和/或，终端设备上报的可同时接收的下行band/CC总带宽小于等于可同时激活的下行band/CC总带宽。在可配置的M个band/CC内，上行载波和下行载波可以打破band灵活配对，比如一个服务小区包括了载波频率为1.8G的上行和载波频率为700MHz的下行。在可切换的L个band/CC组合内，网络设备可以根据不同上行载波的信道测量结果和资源负载情况灵活选择上行或下行载波。在一些可能的示例中，终端能力上报终端的总接收和/或发送通道数和/或可切换的通道数，例如，上报哪些通道和/或多少通道数可以在哪些band/CC组合里互相切换。
示例的，以上行为例，终端设备只上报上述能力中的两种，即上报第一上行band/CC组合和第二上行band/CC组合，第一上行band/CC组合为可同时配置的band/CC组合，第二上行band/CC组合为可同时激活的band/CC组合，也为可同时传输的band/CC组合，可 选地，第二组合是第一组合的子集，或者第一组合里的band/CC个数大于第二组合里的band/CC个数，即上述M>K＝m。如此，基站基于上报的能力，可以给终端设备配置小于等于M个上行载波/上行band，然后通过RRC信令或MAC CE信令或DCI信令对上行载波在配置的载波里动态的选择1个或几个载波快速激活去激活，保证同一时刻激活的载波数小于等于K，可以实现终端设备快速地在M个不同上行载波之间快速切换，从而更加高效的根据当前的信道状况和业务特性利用M个上行载波的资源，避免了通过RRC载波重配置信令进行上行载波切换造成的时延。若UE还上报了总通道数，和/或，哪些通道和/或多少通道数可以在哪些band/CC组合里互相切换，则上述切换需要考虑该能力。
示例的，以上行为例，终端设备只上报上述能力中的两种，即上报第一上行band/CC组合和第二上行band/CC组合，第一上行band/CC组合为可同时配置的band/CC组合，也为可同时激活的band/CC组合，第二上行band/CC组合为可同时传输的band/CC组合，可选地，第二组合是第一组合的子集，或者第一组合里的band/CC个数大于第二组合里的band/CC个数，即上述M＝K>m。如此，基站基于上报的能力，可以给终端设备配置并激活小于等于M个上行载波/上行band，然后通过DCI信令在配置的或激活的载波里动态的选择1个或几个载波切换，保证同一时刻传输载波数小于等于m，可以实现终端设备更加快速地在M个不同上行载波之间快速切换，从而更加高效的根据当前的信道状况和业务特性利用M个上行载波的资源，避免了通过RRC载波重配置信令进行上行载波切换造成的时延，或者通过MAC CE信令激活/去激活上行载波造成的时延。若UE还上报了总通道数，和/或，哪些通道和/或多少通道数可以在哪些band/CC组合里互相切换，则上述切换需要考虑该能力。
示例的，以上行为例，终端设备上报上述能力中的三种，即上报第一上行band/CC组合，第二上行band/CC组合和第三band/CC组合，第一上行band/CC组合为可同时配置的band/CC组合，第二上行band/CC组合为可同时激活的band/CC组合，第三上行band/CC组合为可同时传输的band/CC组合，可选地，第三组合是第二组合的子集，第二组合是第一组合的子集，或者第一组合里的band/CC个数大于第二组合里的band/CC个数，第二组合里的band/CC个数大于第三组合里的band/CC个数，即上述M>K>m。如此，基站基于上报的能力，可以给终端设备配置小于等于M个上行载波/上行band，然后激活小于等于M个上行载波/上行band，然后通过DCI信令对上行载波切换，保证同一时刻调度的传输载波数小于等于m，可以实现终端设备更加快速地在M个不同上行载波之间快速切换，从而更加高效的根据当前的信道状况和业务特性利用M个上行载波的资源，避免了通过RRC载波重配置信令进行上行载波切换造成的时延，或者通过MAC CE信令激活/去激活上行载波造成的时延。若UE还上报了总通道数，和/或，哪些通道和/或多少通道数可以在哪些band/CC组合里互相切换，则上述切换需要考虑该能力。
band/CC个数M或者band/CC总带宽或带宽组合类似，不再赘述。
下行类似，不再赘述。
以CC组合为例，如图16A所示，终端设备上报的可同时配置的CC组合为CC1、CC2、CC3和CC4；终端上报的可同时激活的CC组合为CC1、CC2、CC3和CC4，即可同时激活的CC的个数为4个，则终端可切换的CC组合为CC1、CC2、CC3和CC4；终端上报的可同时传输的CC组合为CC3和CC4，即可同时传输的CC的数目最大为2个。例如，终端设备用于传输的CC从CC2切换到CC3和CC4，即将CC2使用的通道切换到CC3和 CC4。例如，CC2使用的通道为两个，分别为通道1和通道2，可以将通道1切换到CC3，将通道2切换到CC4。基站可以通过DCI信令通知用户将CC2使用的通道切换到CC3和CC4。将CC2使用的通道切换到CC3和CC4所需要的时延大概为1～4个符号。
再例如，如图16B所示，终端设备上报的可同时配置的CC组合为CC1、CC2、CC3和CC4；终端上报的可同时激活的CC组合一为CC1和CC2，可同时激活的CC组合二为CC3和CC4，其中，CC1和CC2可以同时激活，CC3和CC4可以同时激活，即可同时激活的CC个数为2个。终端上报的可同时传输的CC组合为CC3和CC4，其中，CC3和CC4可同时传输，即可同时传输的CC个数最大为2个。例如，当可同时激活的CC组合一CC1和CC2处于激活状态时，终端设备可以将CC1使用的通道切换到CC2。例如，终端设备将可同时激活的CC组合一CC1和CC2去激活，终端设备将可同时激活的CC组合二CC3和CC4激活。例如，当可同时激活的CC组合二CC3和CC4处于激活状态时，由于CC3和CC4也为可同时传输的CC组合，终端设备可以同时在CC3和CC4上传输。
以上两个例子是以CC组合为例，band组合或者服务小区组合或者CC/band带宽组合类似，不再赘述。其中图16A和图16B例子中的CC组合可以是上行CC组合，也可以是下行CC组合，本申请不做限制。
在本申请另一些实施例中，终端设备是根据时间图样进行服务小区状态的切换的。而时间图样可是以网络设备指示给终端设备的，或者是通过协议预定义的。网络设备可以向终端设备发送时间图样配置信令或时间图样激活信令，从而实现服务小区状态的切换。关于时间图样可以参见载波状态中关于时间图样的相关介绍，在此不再赘述。示例的，时间图样配置信令或者时间图样激活信令可以为DCI、RRC信令或者MAC CE信令等，对此不作限定。
或者，在一些实施例中，网络设备可以根据上行的数据调度来隐式的指示一个服务小区状态的切换。比如在同一个时间单元，网络设备调度了终端设备在服务小区1上的上行载波上使用1端口(port)发送PUSCH，在服务小区2的上行载波上使用1port发送PUSCH，那么服务小区1和服务小区2的服务小区状态均为激活态，而终端设备其他激活的服务小区的服务小区状态为第一状态。
另外，终端设备在上行载波上是通过端口/通道/发送天线实现上行通信的。而针对上行载波使用或配置的端口/通道/发送天线是由网络设备指示给终端设备的。然而，在网络设备为终端设备配置多个上行载波的情况下，网络设备通常分别给每个上行载波配置一个或多个端口/通道/发送天线，且针对不同上行载波配置的端口/通道/发送天线是不同的，即使在某一个上行载波未进行上行通信的情况下，针对该上行载波配置的端口/通道也不能被其他上行载波使用，从而容易资源浪费，影响通信效率。有鉴于此，本申请实施例提供了一种通信方法，以终端设备在上行载波上通过端口实现上行通信为例，如图5所示，可以应用于CA、DC或者SUL场景或者CA和SUL组合的场景，具体包括以下步骤，终端设备在上行载波上通过通道/发送天线实现上行通信的方式是类似的，可以参照。
501、终端设备在第一载波上通过N个端口进行上行通信，N为正整数。
502、网络设备向终端设备发送第二指令，其中，第二指令用于指示在第二载波上使用Q个端口进行上行通信，Q个端口包括上述步骤501中第一载波使用的N个端口中的K 个端口，其中，Q为正整数，0＜K≤N，N-K+Q不超过所述终端设备的上行通信支持的最大端口数。
503、终端设备根据第二指令，在第二载波上通过Q个端口进行上行通信。
在本申请实施例中，由于网络设备可以将配置给第一载波的端口配置给第二载波使用，从而提高了端口的利用率，有助于提高终端设备的通信效率。
其中，第一载波和第二载波可以为终端设备同一服务小区的两个上行载波，也可以为终端设备的不同服务小区的两个上行载波，对此不作限定。其中第一载波和第二载波并没有限定本申请实施例中只包括两个载波的情况，终端设备可以在大于两个载波上分配和切换端口数。另外，本申请实施例中，第一载波和第二载波可以属于同一频段，也可以属于不同的频段。
在一种实现方式中，终端设备在第一载波上通过N个端口进行上行通信时，也可以在第二载波上通过M个端口进行上行通信，其中M+N不超过终端设备的上行通信支持的最大端口数。而且，第一载波使用的N个端口和第二载波使用的M个端口是不同的。也就是说，终端设备在同一时间单元可以在第一载波和第二载波上使用不同的端口进行上行通信。在这种情况下，如果终端设备接收到第二指令，则第二载波上使用的Q个端口可以包括之前使用的M个端口和第一载波使用的N个端口中的K个端口。
在另一种实现方式中，终端设备在第一载波上通过N个端口进行上行通信时，在第二载波上不进行上行通信，在这种情况下，如果终端设备接收到第二指令，则第二载波上使用的Q个端口至少包括第一载波使用的N个端口中的K个端口。
可以理解的是，在K的取值等于N的情况下，终端设备接收到第二指令，则终端设备后续不在第一载波上进行上行通信。在K的取值小于N的情况下，终端设备接收到第二指令后，可以继续在第一载波上通过N-K个上行载波进行上行通信。可选的，相同的端口也可以对应不同的上行载波，即终端设备在至少两个上行载波上可以使用相同的端口进行上行传输。例如，在频段上连续的两个上行载波可以对应相同的端口。
示例的，网络设备可以将第二指令携带在DCI中发送给终端设备，也可以将第二指令携带在RRC信令或者MAC CE信令中发送给终端设备，还可以将第二指令携带在其它信息中发送给终端设备，对此不作限定。
在一些实施例中，网络设备可以动态或半静态向终端设备发送更新上行载波使用的端口数。示例的，网络设备可以通过事件触发向终端设备发送第二指令。例如，网络设备在检测到第一载波上需要传输的数据量小于大于或等于某一阈值时，向一些终端设备发送第二指令，指示终端设备在其他上行载波上进行传输，从而达到网络负载均衡的目的。第二指令还可以用于指示终端设备在第一载波上不进行上行通信。即第一载波使用的端口数为0。再例如，网络设备在检测到第二载波上需要传输的数据量大于第一载波上需要传输的数据量时，向终端设备发送第二指令。在另一些实施例中，网络设备还可以周期性更新上行载波使用的端口数，使得终端设备可以周期性切换到上行载波上进行上行通信。比如终端设备周期的切换到某个上行载波发送SRS。
例如，以终端设备上行通信支持的最大端口数为2为例，如图6A所示，终端设备在时隙1和时隙2、中心频率为2.1GHz的上行载波上使用1个端口(port，可以简称为P)进行上行通信，在时隙1和时隙2、中心频率为1.8GHz的上行载波上使用另1个端口进行上行通信，在时隙4、中心频率为2.1GHz的上行载波上不进行上行通信，如果终端设备在 时隙4需要在中心频率为1.8GHz的上行载波上进行上行通信，则在时隙4，中心频率为1.8GHz的上行载波可以使用两个端口进行上行通信，从而有助于提高通信效率。
例如，以终端设备上行通信支持的最大端口数为4为例，如图6B所示，终端设备在时隙1和时隙2、中心频率为2.1GHz的上行载波上使用3个端口进行上行通信，在时隙1和时隙2、中心频率为1.8GHz的上行载波上使用另外1个端口进行上行通信，在时隙4、中心频率为2.1GHz的上行载波上使用1个端口进行上行通信，如果终端设备在时隙4需要在中心频率为2.1GHz的上行载波上使用1个端口进行上行通信，则在时隙4，中心频率为1.8GHz的上行载波可以使用2个或3个端口进行上行通信，从而有助于提高通信效率。具体的，在时隙4，中心频率为1.8GHz的上行载波可以进行上行通信使用的端口数可以是网络设备指示的，也可以是终端设备根据自身的数据传输需求设置的。比如，在时隙4如果中心频率为2.1GHz的上行载波的端口数为1的情况下，在时隙4，除了在中心频率为1.8GHz的上行载波进行上行通信以外，还需要在中心频率为3.5GHz的上行载波上进行上行通信，则终端设备可以在时隙4，在中心频率为1.8GHz的上行载波可以使用2个端口进行上行通信，在中心频率为3.5GHz的上行载波上使用1个端口进行上行通信。
又例如，以终端设备上行通信支持的最大端口数为2为例，如图6C所示，终端设备在时隙1和时隙2、中心频率为2.1GHz的上行载波上使用1个端口进行上行通信，在时隙1和时隙2、中心频率为1.8GHz的上行载波上使用另1个端口进行上行通信，在时隙4、中心频率为2.1GHz和1.8GHz的上行载波上不进行上行通信，如果终端设备在时隙4需要在中心频率为3.5GHz的上行载波上进行上行通信，则在时隙4，中心频率为3.5GHz的上行载波可以使用2个端口进行上行通信，在这种情况下，在时隙4，中心频率为2.1GHz和1.8GHz的上行载波使用的端口数为0，从而有助于提高通信效率。
例如，以终端设备上行通信支持的最大端口数为3为例，如图6D所示，终端设备在时隙1和时隙2、中心频率为2.1GHz的上行载波上使用2个端口进行上行通信，在时隙1和时隙2、中心频率为1.8GHz的上行载波上使用另外1个端口进行上行通信，在时隙4、中心频率为2.1GHz的上行载波上使用1个端口进行上行通信，如果终端设备在时隙4不需要在中心频率为1.8GHz的上行载波上进行上行通信，在时隙4中心频率为3.5GHz的上行载波需要进行上行通信的情况下，在时隙4中心频率为3.5GHz的上行载波可以使用2个端口进行上行通信，从而有助于提高通信效率。或者，终端设备如果在时隙4、中心频率为2.1GHz的上行载波上使用1个端口进行上行通信，在时隙4、中心频率为1.8GHz的上行载波上使用1个端口进行上行通信，则在时隙4中心频率为3.5GHz的上行载波需要进行上行通信的情况下，在时隙4中心频率为3.5GHz的上行载波可以使用1个端口进行上行通信。
在另一些实施例中，终端设备在接收到第二指令后经过第一时长，再在第二载波上通过N个端口中的K个端口进行上行通信，第一时长为第二载波上端口个数发生切换时需要的切换时延。从而有助于提高上行通信的可靠性。示例的，第一时长的起始时刻可以是由网络设备指示给终端设备，也可以是由终端设备根据某一策略确定的、或者第一时长的起始时刻为通过协议定义的。例如，第一时长的起始时刻为终端设备接收到第二指令的时刻，或为终端设备接收并解析了第二指令内容的时刻。第一时长可以是通过协议预定义的，也可以是由网络设备指示给终端设备的，或者是终端设备上报的。示例的，第一时长可以以时间单元为单位来定义，也可以为绝对时间，对此不作限定。例如，第一时长为一个参考 参数集(numerology)的固定符号的个数，参考numerology可以是预定义或与配置的，也可以与某一上行载波(如主小区的上行载波、第一载波或第二载波)上激活的BWP的numerology相同，针对不同numerology，第一时长对应的符号个数可以不同。可选的，第一时长与源band组合、目标band组合、源上行载波的频段、目标上行载波的频段、源端口数、目标端口数、源发送天线数、目标发送天线数、源发送通道数、目标发送通道数、源载波数、目标载波数中的至少1个相关。其中band组合和载波频段是第一时长与发生切换的载波对应的band组合/频段有关。源端口数是指针对第二载波的端口数切换到Q个之前终端设备在第二载波上的端口数，源发送天线数是指针对第二载波的端口数切换到Q个之前终端设备在第二载波上的发送天线数，源发送通道数是指针对第二载波的端口数切换到Q个之前终端设备在第二载波上的通道数，目标端口数是指针对第二载波的端口数切换到Q个后终端设备在第二载波上的端口数，目标发送天线数是指针对第二载波的端口数切换到Q个后终端设备在第二载波上的发送天线数，目标通道数是指针对第二载波的端口数切换到Q个后终端设备在第二载波上的通道数，源载波数是指终端设备在第二载波的端口数切换前同时发送的上行载波数，目标载波数是终端设备在第二载波的端口数切换后同时发送的上行载波数。
示例的，本申请实施例的对于属于同一频段的载波间的端口/发送通道切换时延、属于不同频段的载波间的端口/发送通道切换时延、和/或不同端口个数的端口/发送通道切换时延可以是统一的，从而有助于简化实现。或者，针对以上不同情况配置不同的端口/发送通道切换时延。在这种情况下，可以根据载波和/或载波所属的频段、或者端口数的切换情况确定端口切换时延。进一步的，在一些实施例中，针对以上不同情况的端口/发送通道切换，终端设备获取终端切换时延的能力信息，终端设备可以分别上报切换时延能力。具体的，针对不同的载波/载波频段上的端口/发送通道切换情况、或者不同的端口/发送通道数的情况，终端设备可以分别上报切换时延。例如，从0个端口切换到1个端口、从载波1切换到载波2、且载波1和载波2属于不同频段的端口切换时延为时延1。再例如，从1个端口切换到2个端口、从载波2切换到载波3、且载波2和载波3属于同一频段的端口切换时延为时延2。终端设备分别上报时延1和时延2。
例如，针对同一载波从1个端口切换到2个端口和从0个端口切换到2个端口需要的切换时延不同。再例如，针对不同载波之间的端口切换时延也可能不同。比如，从载波1切换到载波2、与从载波2切换到载波3所需的切换时长不同。再例如，针对不同载波上的端口切换时延也可能不同。比如，终端设备在载波4上从0个端口切换到2个端口的时延为t1，终端设备在载波5上从0个端口切换到2个端口的时延为t2。终端设备分别上报时延t1和时延t2。
示例的，“band/载波1的两个通道切换到band/载波1的一个通道和band/载波2的一个通道的时延t1”、“band/载波1的两个通道切换到band/载波1的零个通道和band/载波2的两个通道的时延t2”、“band/载波1的两个通道切换到band/载波1的零个通道、band/载波2的一个通道和band/载波3的一个通道的时延t3”中至少有2个不一样。
在另一些实施例中，终端设备向网络设备上报能力信息，该能力信息包括终端设备支持的频段、以及终端设备支持的频段所支持的最大端口数，以便于网络设备针对为终端设备配置的服务小区的上行载波配置相应的端口数。进一步的，终端设备向网络设备上报的 能力信息还可以包括终端设备上行通信支持的最大端口数。
以第一载波为例。需要说明的是，本申请实施例中，终端设备在第一载波上使用的端口数与终端设备在第一载波上配置的通道数相关。需要说明的是，终端设备在第一载波上使用的端口数是由网络设备配置的。其中，在第一载波上配置的端口数小于或等于在第一载波上配置或终端设备上报的通道数。例如，在第一载波上配置的通道数为1，则在第一载波上配置的端口数可以为1，也可以为0。再例如，在第一载波上配置的通道数为2，则在第一载波上配置的端口数可以为2、1或0。又例如，在第一载波上配置的通道数为0，则在第一载波上配置的端口数可以为0。
本申请实施例中，终端设备在一个载波上的上行发送通道是指终端设备在所述上行载波上用于发送的射频通道，对应一个功率放大器；终端设备在一个载波上的上行发送天线是指终端设备在所述载波上用于发送的物理天线；终端设备在一个载波上的上行发送端口是指终端设备在所述载波上发送信号对应的逻辑端口号，每个端口号上有自己独立的DMRS信号，供网络设备解调出各个端口上的信号。终端设备在一个下行载波上的下行接收通道是指终端设备在所述下行载波上用于接收的射频通道；终端设备在一个载波上的下行接收天线是指终端设备在所述载波上用于接收的物理天线；终端设备在一个载波上的下行接收端口是指终端设备在所述载波上接收信号对应的逻辑端口号。
网络设备在一个上行载波上的上行接收通道是指网络设备在所述上行载波上用于接收的射频通道；终端设备在一个上行载波上的上行接收天线是指终端设备在所述载波上用于接收的物理天线；终端设备在一个上行载波上的上行接收端口是指终端设备在所述载波上接收信号对应的逻辑端口号。网络设备在一个下行载波上的下行发送通道是指网络设备在所述载波上用于发送的射频通道；网络设备在一个下行载波上的下行发送天线是指网络设备在所述载波上用于发送的物理天线；终端设备在一个下行载波上的下行发送端口是指终端设备在所述载波上发送信号对应的逻辑端口号。
通道，端口和天线的关系为：终端设备在一个上行载波上最大上行发送天线数大于等于最大上行发送通道数，大于等于最大发送端口数，终端设备在一个下行载波上最大接收天线数大于等于最大下行接收通道数，大于等于最大接收端口数；网络设备在一个上行载波上最大上行接收天线数大于等于最大上行接收通道数，大于等于最大接收端口数，网络设备在一个下行载波上最大发送天线数大于等于最大下行发送通道数，大于等于最大发送端口数；网络设备可以配置通道数，端口数和天线数三者中至少一个给终端设备，从而实现网络设备和终端设备之间的通信。
以终端设备配置有第一载波和第二载波、终端设备上行通信支持的最大上行通道数为2为例，载波的通道数和端口数之间的关系可以如表1所示。

因此，基于表1，上述步骤501～步骤503中的端口也可以替换为通道、或发送天线，具体实现可以参见端口的相关介绍，在此不在赘述。示例的，对于通道切换时延，例如载波从1个通道切换到2个通道的切换时延可以为30KHz的1个符号，载波从0个通道切换到2个通道的切换时延可以为30KHz的2个符号，也可以为绝对时间，例如70us。
此外，在本申请的另一些实施例中，网络设备还可以针对为终端设备配置的上行载波配置一个或多个时间图样。时间图样规定了上行载波在哪些时间单元使用哪些端口/通道/发送天线。在这种情况下，网络设备无需发送第二指令，针对上行载波使用的端口/通道/发送天线进行切换。
示例的，每个上行载波可以对应一个时间图样，或者针对终端设备配置的所有上行载波对应一个时间图样。以一个上行载波对应一个时间图样、终端设备上行通信支持的最大端口数为2为例，例如，网络设备针对终端设备配置的上行载波包括第一载波和第二载波，第一载波的时间图样为时间图样1，包括10个时间单元，终端设备针对第一载波在前3个时间单元可以使用2个端口(例如端口1和端口2)进行上行通信，在第4～7个时间单元可以使用1个端口(例如端口1)进行上行通信，在后3个时间单元不使用端口进行上行通信。第二载波的时间图样为时间图样2，也包括10个时间单元，终端设备针对第二载波在前3个时间单元不使用端口进行上行通信，在第4～7个时间单元可以使用1个端口(例如端口2)进行上行通信，在后3个时间单元可以使用2个端口(例如端口1和端口2)进行上行通信。
示例的，终端设备在接收到网络设备针对上行载波配置的新的时间图样之前，可以周期性使用之前配置的时间图样，进行上行通信。或者，网络设备可以周期性针对上行载波为终端设备配置时间图样。
需要说明的是，本申请实施例如果从单载波角度考虑的话，以第一载波为例，终端设备在第一时间单元和第一载波上通过N个端口进行上行通信，终端设备在第二时间单元和第一载波上通过M个端口进行上行通信，其中N和M为大于或等于0的正整数，且N和M不相等。示例的，终端设备针对第一载波可以根据网络设备的切换指令，在第二时间单元从N个端口切换到M个端口。或者，终端设备根据第一载波的时间图样，在第二时间单元从N个端口切换到M个端口。
终端设备在下行载波上是通过端口/通道/接收天线实现下行通信的。而针对下行载波使用或配置的端口/通道/接收天线是由网络设备指示给终端设备的。然而，在网络设备为终端设备配置多个下行载波的情况下，网络设备通常分别给每个下行载波配置一个或多个端口/通道/接收天线，且针对不同下行载波配置的端口/通道/接收天线是不同的，即使在某一个下行载波未用于进行下行通信的情况下，针对该下行载波配置的端口/通道/接收天线也不能被其他下行载波使用，从而容易资源浪费，影响通信效率。有鉴于此，本申请实施例提供了另一种通信方法，可以应用于CA、或DC场景，以端口为例，如图7所示，具体包括以下步骤。
701、终端设备在第一载波上通过N个端口进行下行通信，N为正整数；
702、网络设备向终端设备发送第三指令，第三指令用于指示在第二载波上使用Q个端口进行下行通信，第二载波使用的Q个端口包括上述第一载波使用的N个端口中的K个端口，K、Q为正整数，且0＜K≤N，N-K+Q不超过终端设备的下行通信支持的最大端 口数。
703、终端设备在接收到第三指令，根据第三指令，在第二载波上通过Q个端口进行下行通信。
关于第一载波、第二载波可以参见图5所示的通信方法中的相关介绍，在此不再赘述。
图7中的端口也可以替换为接收天线、通道，即终端设备在一个下行载波上的下行接收能力可以借用其他载波的下行接收能力。示例的，网络设备可以动态调度终端设备在不同载波上进行端口的切换。例如，第三指令可以携带在DCI中发送给终端设备。或者，第三指令可以为CSI-RS，通过不同端口配置的CSI-RS配置和发送来隐式的指示终端设备接收能力的切换。其中，不同的端口数对应的CSI-RS不同。其中，不同的端口数对应的CSI-RS可以是网络设备指示给终端设备的，也可以是通过协议预定义的，对此不作限定。或者，第三指令还可以为不同的调度参数，例如MCS、RI或PMI等，其中，不同的端口数对应的调度参数不同。
进一步的，在一些实施例中，终端设备在接收到第三指令的第二时长后，在第二载波上通过K个端口进行下行通信，第二时长为第二载波与第一载波之间的端口切换时延。关于第二时长、和第二时长的起始时刻可以参见图5所示的通信方法中的相关介绍，在此不在赘述。
可选的，第二时长与源band组合、目标band组合、源下行载波的频段、目标下行载波的频段、源端口数、目标端口数、源接收天线数、目标接收天线数、源接收通道数、目标接收通道数、源载波数、目标载波数中的至少1个相关。其中band组合和载波频段与第二时长与发生切换的载波对应的band组合/频段有关。源端口数是指针对第二载波的端口数切换到Q个之前终端设备在第二载波上的端口数，源接收天线数是指针对第二载波的端口数切换到Q个之前终端设备在第二载波上的接收天线数，源接收通道数是指针对第二载波的端口数切换到Q个之前终端设备在第二载波上的通道数，目标端口数是指针对第二载波的端口数切换到Q个后终端设备在第二载波上的端口数，目标接收天线数是指针对第二载波的端口数切换到Q个后终端设备在第二载波上的接收天线数，目标通道数是指针对第二载波的端口数切换到Q个后终端设备在第二载波上的通道数，源载波数是指终端设备在第二载波的端口数切换前同时接收的上行载波数，目标载波数是终端设备在第二载波的端口数切换后同时接收的上行载波数。
示例的，本申请实施例的对于属于同一频段的载波间的端口/接收通道切换时延、属于不同频段的载波间的端口/接收通道切换时延、和/或不同端口个数的端口/接收通道切换时延可以相同的，从而有助于简化实现。或者，针对以上不同情况配置不同的端口/接收通道切换时延。在这种情况下，可以根据载波和/或载波所属的频段、或者端口数的切换情况确定端口切换时延。进一步的，在一些实施例中，针对以上不同情况的端口/接收通道切换，终端设备分别获取对应的终端切换时延的能力信息，终端设备可以分别上报切换时延能力。具体的，针对不同的载波/载波频段上的端口/接收通道切换情况、或者不同的端口/接收通道数的情况，终端设备可以分别上报切换时延。例如，从0个端口切换到1个端口、从载波1切换到载波2、且载波1和载波2属于不同频段的端口切换时延为时延1。再例如，从1个端口切换到2个端口、从载波2切换到载波3、且载波2和载波3属于同一频段的端口切换时延为时延2。终端设备分别上报时延1和时延2。
例如，针对同一载波从1个端口切换到2个端口和从0个端口切换到2个端口需要的 切换时延不同。再例如，针对不同载波之间的端口切换时延也可能不同。比如，从载波1切换到载波2、与从载波2切换到载波3所需的切换时长不同。再例如，针对不同载波上的端口切换时延也可能不同。比如，终端设备在载波4上从0个端口切换到2个端口的时延为t1，终端设备在载波5上从0个端口切换到2个端口的时延为t2。终端设备分别上报时延t1和时延t2。
示例的，“band/载波1的两个通道切换到band/载波1的一个通道和band/载波2的一个通道的时延t1”、“band/载波1的两个通道切换到band/载波1的零个通道和band/载波2的两个通道的时延t2”、“band/载波1的两个通道切换到band/载波1的零个通道、band/载波2的一个通道和band/载波3的一个通道的时延t3”中至少有2个不一样。
在本申请的另一些实施例中，终端设备还可以向网络设备上报第一指示信息，第一指示信息用于指示终端设备是否支持载波间端口切换能力或是否支持在一个载波上端口个数发生切换，包括终端设备上行发送和下行接收，即终端设备是否支持不同载波上配置的端口的切换，以便于网络设备向终端设备发送端口切换指令(例如第三指令)。
本申请实施例中，由于终端设备能够在支持载波间端口切换能力的情况下，实现端口在不同载波间的切换，从而有助于增强终端设备的下行体验。例如，终端设备在第一载波上支持的最大端口数为4，在第二载波上支持的最大端口数为2，如果终端设备下行通信支持的最大端口数为4，在第一载波上配置有2个端口，在第二载波上配置有2个端口的情况下，如果第二载波上没有下行通信需求，则第一载波可以借用第二载波上配置的2个端口，从而使得第一载波可以通过4个端口进行通信，从而提高了通信效率。
以终端设备在第一载波上支持的最大端口数为4为例，在终端设备在第一载波和第二载波上支持的最大端口数均为4的情况下，如图8所示，在时隙1上在第一载波上配置有2个端口，在第二载波上配置有2个端口，即终端设备在时隙1，在第一载波和第二载波上分别使用2个端口进行下行通信；在时隙2上在第一载波上配置有4个端口，在第二载波上配置有0个端口，即终端设备在时隙2，在第一载波使用4个端口进行下行通信，不在第二载波进行下行通信；在时隙3上在第一载波上配置有0个端口，在第二载波上配置有4个端口，即终端设备在时隙3，在第二载波使用4个端口进行下行通信，不在第一载波进行下行通信。
需要说明的是，对于终端设备来说，还可以通过接收天线数、通道数衡量终端设备的下行接收能力。因此，步骤701～步骤703中的端口还可以替换为接收天线或通道。
需要说明的是，在本申请的另一些实施例中，网络设备还可以针对为终端设备配置的下行载波配置一个或多个时间图样。时间图样规定了下行载波在哪些时间单元使用哪些端口/通道/接收天线。在这种情况下，网络设备无需发送第三指令，针对下行载波使用的端口/通道/接收天线进行切换。示例的，每个下行载波可以对应一个时间图样，或者针对终端设备配置的所有下行载波对应一个时间图样。以一个下行载波对应一个时间图样、终端设备下行通信支持的最大端口数为3为例，例如，网络设备针对终端设备配置的下行载波包括第一载波和第二载波，第一载波的时间图样为时间图样1，包括10个时间单元，终端设备针对第一载波在前3个时间单元可以使用3个端口(例如端口1、端口2和端口3)进行上行通信，在第4～7个时间单元可以使用1个端口(例如端口1)进行上行通信，在后3个时间单元不使用端口进行上行通信。第二载波的时间图样为时间图样2，也包括10 个时间单元，终端设备针对第二载波在前3个时间单元不使用端口进行下行通信，在第4～7个时间单元可以使用2个端口(例如端口2和端口3)进行下行通信，在后3个时间单元可以使用3个端口(例如端口1、端口2和端口3)进行下行通信。
示例的，终端设备在接收到网络设备针对下行载波配置的新的时间图样之前，可以周期性使用之前配置的时间图样，进行下行通信。或者，网络设备可以周期性针对下行载波为终端设备配置时间图样。
需要说明的是，本申请实施例如果从单载波角度考虑的话，以第一载波为例，终端设备在第一时间单元和第一载波上通过N个端口进行下行通信，终端设备在第二时间单元和第一载波上通过M个端口进行下行通信，其中N和M为大于或等于0的正整数，且N和M不相等。示例的，终端设备针对第一载波可以根据网络设备的切换指令，在第二时间单元从N个端口切换到M个端口。或者，终端设备根据第一载波的时间图样，在第二时间单元从N个端口切换到M个端口。
此外，本申请实施例中网络设备针对下行载波可以具有固定的下行发送能力。具体的，网络设备针对下行载波的下行发送能力可以通过发送天线数或者用于下行通信的端口数(又可以称之为发送天线端口数)衡量。例如，以第一载波和第二载波为例，网络设备针对第一载波的发送天线数为64，针对第二载波的发送天线数也为64，则网络设备通常在第一载波上使用64个发送天线进行下行通信，在第二载波上使用64个发送天线进行下行通信，现有技术中，当网络设备在第二载波上不进行下行通信时，一般在第二载波上进行下行通信的天线个数也不会超过64。因而容易导致资源浪费。
有鉴于此，本申请实施例还提供了一种通信方法，如图9所示，可以应用于CA或DC场景，具体包括以下步骤。
901、网络设备在第一时间单元和第一载波上通过N个发送天线进行下行通信，以及在第一时间单元和第二载波上通过M个发送天线进行下行通信，M、N为正整数。
902、网络设备在第二时间单元和第二载波上通过P个发送天线进行下行通信，P为正整数，且M＜P≤M+N，该P个发送天线包括第二载波使用的M个发送天线和第一载波使用的N个发送天线中的至少一个发送天线，网络设备在第二时间单元上不在第一载波上进行下行通信。
需要说明的是，图9所示的通信方法中，第一载波和第二载波可以为不同终端设备的下行载波，也可以为同一终端设备的不同服务小区的下行载波，第一载波和第二载波可以为同一终端设备一个服务小区内的下行载波，也可以为同一终端设备不同服务小区内的下行载波，对此不作限定。
例如，以下行载波1和下行载波2为例。网络设备针对下行载波1的发送天线(transmit antenna，简称T)数为64，针对下行载波2的发送天线数也为64，如图10所示，网络设备在时间单元1和下行载波1上使用64个发送天线进行下行通信，在时间单元1和下行载波2上使用64个发送天线进行下行通信。在时间单元2和下行载波2上使用128个发送天线进行下行通信，在时间单元2不在下行载波1上进行通信。在时间单元3和下行载波1上使用128个发送天线进行下行通信，在时间单元3不在下行载波2上进行下行通信。从而有助于提高下行通信效率。
可以理解的是，上述步骤901～步骤902中的发送天线可以替换为发送天线端口、或者 通道。
与下行载波类似，本申请实施例中网络设备针对上行载波具有固定的上行接收能力。具体的，网络设备针对上行载波的上行接收能力可以通过接收天线数或者用于上行通信的端口数(又可以称之为接收天线端口数)衡量。例如，以第一载波和第二载波为例。网络设备针对第一载波的接收天线数为64，针对第二载波的接收天线数也为64，则网络设备通常在第一载波上使用64个发接收天线进行上行通信，在第二载波上使用64个发接收天线进行上行通信，现有技术中，网络设备当在第二载波上不进行上行通信时，一般在第二载波上进行上行通信的天线个数也不会超过64。因而容易导致资源浪费。
有鉴于此，本申请实施例还提供了一种通信方法，如图11所示，可以应用于CA或DU场景，具体包括以下步骤。
1101、网络设备在第一时间单元和第一载波上通过N个接收天线进行上行通信，以及在第一时间单元和第二载波上通过M个接收天线进行上行通信，M、N为正整数。
1102、网络设备在第二时间单元和第二载波上通过P个接收天线进行上行通信，P为正整数，且M＜P≤M+N，该P个接收天线包括第二载波使用的M个接收天线和第一载波使用的N个接收天线中的至少一个接收天线，网络设备在第二时间单元上不在第一载波上进行上行通信。
需要说明的是，图11所示的通信方法中，第一载波和第二载波可以为不同终端设备的上行载波，也可以为同一终端设备的不同服务小区的上行载波，第一载波和第二载波可以为同一终端设备一个服务小区内的上行载波，也可以为同一终端设备不同服务小区内的上行载波，对此不作限定。
例如，以上行载波1和上行载波2为例。网络设备针对上行载波1的接收天线(receiving antenna，简称R)数为64，针对上行载波2的接收天线数也为64，如图12所示，网络设备在时间单元1和上行载波1上使用64个接收天线进行上行通信，在时间单元1和上行载波2上使用64个接收天线进行上行通信。在时间单元2和上行载波2上使用128个接收天线进行上行通信，在时间单元2不在上行载波1上进行通信。在时间单元3和上行载波1上使用128个接收天线进行上行通信，在时间单元3不在上行载波2上进行上行通信。从而有助于提高上行通信效率。
可以理解的是，上述步骤1101～步骤1102中的接收天线可以替换为接收天线端口、或者通道。
另外，本申请实施例中，针对一些上行通信占主导的业务场景，例如城市监控、智能工厂等，网络设备可以针对终端设备配置的上行载波/band/服务小区的个数为M，针对终端设备配置的下行载波/band/服务小区的个数为N，其中M大于N，且M、N为正整数，与针对传统的终端设备配置的下行载波/band/服务小区的个数大于上行载波/band/服务小区的个数相比，更适用于上述业务场景。或者，网络设备针对终端设备配置的同一服务小区包括的上行载波的中心频率和下行载波的中心频率不作限制。在一种情况中，一个服务小区中可以只包含下行载波，不包含上行载波。在另一种情况中，一个服务小区中可以只包含上行载波，不包含下行载波。在另一种情况中，一个服务小区可以包含上行载波，同时包含下行载波，但是上行载波和下行载波属于不同的频段。上述服务小区可以是主小区或者辅小区。另外，在一些可能的示例中，上行主服务小区的上行载波和下行服务小区的 下行载波可以属于不同的频段/频点，例如下行Pcell配置为载波1/band1/服务小区1,上行Pcell配置为载波2/band2/服务小区2。此外，在一些可能的示例中，在小区间切换或者移动性过程中，网络发送Pcell切换指令用于指示下行和上行Pcell可以一起切换，也可以解耦切换，即用于指示下行Pcell切换或上行Pcell切换。比如时刻1，下行Pcell为载波1/band1/服务小区1且上行Pcell配置为载波1/band1/服务小区1，小区间切换或者移动性过程中，网络发送Pcell切换指令用于指示下行Pcell切换为载波2/band2/服务小区2(上行PCell不切换仍然为载波1/band1/服务小区1)，或者发送Pcell切换指令用于指示下行Pcell不切换仍然为载波1/band1/服务小区1但上行Pcell切换为载波2/band2/服务小区2。如此则可以实现下行和上行解耦，Pcell解耦，独立负载均衡，实现上下行一致性体验。另外，在一些可能的示例中，Pcell包含下行主载波和上行主载波，在小区间切换或者移动性过程中，网络层发送Pcell切换指令用于指示Pcell的下行载波/频点/频段和上行载波/频点/频段可以一起切换，也可以解耦切换，即用于指示Pcell的下行载波/频点/频段切换或Pcell的上行载波/频点/频段切换。比如时刻1，网络发送Pcell切换指令用于指示Pcell的下行载波/频点/频段1切换为下行载波/频点/频段2，并且Pcell不切换其上行载波/频点/频段1；或者发送Pcell切换指令用于指示Pcell的上行载波/频点/频段1切换为上行载波/频点/频段2，并且Pcell不切换下行载波/频点/频段1。如此则可以实现下行和上行频点/频段解耦，独立负载均衡，实现上下行一致性体验。再例如，以FDD通信系统中终端设备的一个服务小区为例，该服务小区可以包括一个中心频率为900MHz的上行载波和一个中心频率为3.5GHz的下行载波。从而使得小区配置更为灵活。因此，按照本实施例中的方法，为其配置3.5G下行载波与900MHz的上行载波，这种方法比现有技术配置3.5G上下行载波能获得更好的上行覆盖，比现有技术配置900MHz上下行载波能获得更好的下行容量。
以band为例。如图15所示网络设备为终端设备配置的上行载波分别为UL1、UL2、UL3和UL4，网络设备为终端设备配置的下行载波分别为DL1、DL2、DL3和DL4，其中，UL1和DL1位于频带A内，UL2和DL2位于频带B内，UL3和DL3位于频带C内，UL4和DL4位于频带D内。在这种情况下，网络设备如果指示终端设备激活DL1、UL2、DL3和UL3，则UL1、DL2、UL4和DL4是未激活的。示例的，DL1可以为终端设备的Pcell的下行载波，UL2为终端设备的Pcell的上行载波。
应理解，本申请上述各实施例可以单独使用，也可以相互结合使用，以实现不同的技术效果。
