具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。
需要说明的是，本公开中，任一个实施例提供的方法可以单独执行，实施例中任一实现方式也可以单独执行，或是结合其他实施例，或其他实施例中的可能的实现方法一起被执行，还可以结合相关技术中的任一种技术方案一起被执行。
本公开实施例提供的通信方法，可以应用于无线通信***中。在无线通信***中，移动台通过诸如基站等无线接入网网络设备接入到无线接入网中，无线接入网网络设备与核心网网络设备完成数据的回传和前向传递，以进行各种通信服务。
可以理解的是，无线通信***，是一种提供无线通信功能的网络。无线通信***可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络或***。本公开中网络可包括无线接入网(Radio Access Network，RAN)以及核心网(Core Network，CN)。网络中包括有网络设备，该网络设备可以是无线接入网节点、核 心网功能等。其中，无线接入网节点也可以称为基站。网络可以通过网络设备为终端提供网络服务，不同的运营商可以为终端提供不同的网络服务，也可以理解为不同的运营商对应有不同的运营商网络。
其中，目前的无线通信***支持多无线接入双链接技术(Multi-Radio Dual Connectivity，MR-DC)中小区组(Cell group，CG)的选择性激活(selective activation of cell groups)。
MR-DC是一种泛化的相同演进的通用移动通信***(Universal Mobile Telecommunications System，UMTS)陆面无线接入(Intra Evolved Universal Terrestrial Radio Access，Intra-E-UTRA)双连接。其中，终端可以利用两个不同的调度提供的无线电资源，这些调度位于两个不同的5G无线接入网(NG-RAN)节点上，通过非理想回程连接，一个提供NR访问，另一个提供E-UTRA或NR访问。一个作为主节点(Master Node，MN)，一个作为辅节点(Secondary Node，SN)。MN和SN通过网络接口连接，其中至少有MN连接到核心网络。
其中，4G的分组演进核心网(Evolved Packet Core，EPC)支持MR-DC。其中，E-UTRAN通过(E-UTRA-NR DC，EN-DC)支持MR-DC，其中，EN-DC架构如图1所示。参阅图1所示，终端连接到一个充当MN的eNB和一个充当SN的en-gNB。eNB通过S1接口连接到EPC，通过X2接口连接到en-gNB。en-gNB也可以通过S1-U接口连接到EPC，也可以通过X2-U接口连接到其他en-gNBs。
其中，5G核心网(5GC)支持MR-DC。其中，一种方式中，NG-RAN支持(NG-RAN E-UTRA-NR Dual Connectivity，NGEN-DC)双连接，其中终端连接到一个ng-eNB作为MN，一个gNB作为SN。ng-eNB连接到5GC，gNB通过Xn接口连接到ng-eNB。另一种方式中，NG-RAN支持NR-E-UTRA DC(NR-E-UTRA Dual Connectivity，NE-DC)。其中，终端连接到一个充当MN的gNB和一个充当SN的ng-eNB。gNB连接到5GC，ng-eNB通过Xn接口连接到gNB。又一种方式中，NG-RAN支持(NR-NR DC，NR-DC)。图2示出了一种NR-DC的网络架构图。其中，终端连接到一个充当MN的gNB和另一个充当SN的gNB。主gNB通过NG接口连接到5GC，两个gNB之间通过Xn接口连接，辅gNB也可以通过NG-U接口连接到5GC。此外，NR-DC也可用于UE接入单个gNB，同时作为MN和SN，同时配置MCG和SCG。
在双连接下，终端可以接入两个小区组，分别为主小区组(Master Cell group，MCG)和辅小区组(Secondary Cell group，SCG)。在MCG下，可能会有很多个小区。其中，多个小区中有一个用于发起初始接入的小区，这个小区称为PCell。其中，PCell是MCG里面最“主要”的小区。图3示出了一种双连接下的MCG和SCG的结构示意图。其中， MCG下的PCell和MCG下的SCell通过载波聚合(CA)联合在一起。MCG中的主小区为：PCell，辅小区为：SCell。SCG中的主辅小区为：PSCell，辅小区为：SCell。因为很多信令在PCell和PSCell上发送，为了描述方便，协议中将PCell和PSCell统称为sPCell。sPCell的英文全称为special Cell。
在相关技术中，提出条件切换(CHO)、条件PSCell改变(CPC)以及条件PSCell添加(CPA)。其中，针对CHO/CPC/CPA，终端在对目标PCell/PSCell完成随机接入时必须释放CHO/CPC/CPA配置。因此，如果网络不重新配置和重新初始化CHO/CPC/CPA，终端就没有机会后续继续执行CHO/CPC/CPA。故，会增加切换或者SCG改变的时延并增加信号开销。
因此，提出了MR-DC中小区组的选择性激活(selective activation of cell groups)，其可以使小区组(Cell group，CG)改变后，后续的配置仍然能够执行，无需网络重新配置或者重新初始化相应的小区组选择性激活配置信息，进而可以减少信令开销和小区组改变的中断时长。
其中，小区组选择性激活配置信息可以包括以下至少之一：配置ID，激活条件(可能的)，待激活小区组/小区的配置。
其中，小区组的选择性激活可以使小区组改变后，后续的配置仍然能够执行，无需网络重新配置或者重新初始化相应的小区组选择性激活的配置。故，在小区组的选择性激活中，网络设备可以为终端提供“待激活的小区组”。后续可以对“待激活的小区组”进行激活或去激活，而不用再重新提供小区组的配置。
在小区组的选择性激活中，网络设备可以向终端设备提供预配置的候选的目标小区组或目标小区。后续终端设备可以根据网络设备下发的配置(例如激活消息)或是相应的激活事件将预配置的候选小区组或小区激活或去激活，而不需要重新提供小区组的配置。或者也可以理解为是，在小区组选择性激活中，激活新的小区或小区组，或者应用新的小区配置或小区组配置后或者接入新的小区或小区组后，终端设备不会删除相应的小区组选择性激活的配置信息。
小区组的选择性激活(selective activation of cell groups)，也可以称为小区组激活。小区组激活可以使小区组或小区改变后，相应的配置信息仍然能够执行，无需网络重新配置或者重新初始化相应的小区组激活的配置信息。故，小区组激活可以减少信令开销和小区组改变的中断时长。小区组激活的配置信息可以包括：配置ID以及目标小区的配置或目标小区组的配置。可选的，小区组激活的配置信息还可以包括触发条件(也可以称为执行条件、激活条件)。
在一实施例中，小区组激活是一种移动性管理过程，包括任意一种通过配置小区组激活配置，终端设备根据网络发送的信令，或协议规定的准则，或终端设备自主等方式激活或去激活相应的小区或小区组，或者应用相应的小区配置或小区组配置后或者接入小区或小区组的移动性管理过程。
在一实施例中，小区组激活是一种移动性管理过程，包括任意一种在执行移动性过程后，不删除或释放相应的部分或全部配置信息的移动性管理过程。其中不删除或释放相应的部分或全部配置信息也可以叫做保留相应的部分或全部配置信息。
本公开中，小区组为主小区组(MCG)及辅小区组(SCG)中的一种或多种。其中MCG包括主小区(Primary Cell，PCell)，辅小区(Secondary Cell，SCell)中的一种或多种。其中，SCG包括主辅小区(Primary Secondary Cell，PSCell)，辅小区(SCell)中的一种或多种。
在本公开中，小区组选择性激活可以包括小区选择性激活或小区激活，例如，PCell激活，PSCell激活，SCell激活中的一种或多种。
相关协议中，引入了SCG激活和去激活，但此种方式适用于单个SCG的状态的改变，并不涉及多个SCG的状态的改变。然而，目前已支持引入多个待激活的小区组，从多个待激活的小区组中可以选择性激活小区组。然而，如此可能会涉及到小区组的改变，目前的协议并未规定如何从多个待激活小区组中进行选择性激活小区组的终端的具体行为。即，对于终端进行选择性激活小区的通信行为并未明确。
有鉴于此，本公开提供一种通信方法，在该通信方法中，基于用于小区组选择性激活的配置信息，进行小区组激活处理，从而对终端进行选择性激活小区的通信行为进行明确，以支持小区组选择性激活。
其中，本公开中以下各实施例中涉及的小区组可以是包括一个或多个小区。小区组激活处理可以理解为是小区组/小区激活处理。故，本公开实施例中以下涉及的小区组可以理解为是小区，也可以理解为是小区组。
可以理解的是，本公开以下各实施例中涉及的小区组可以是主小区组(MCG)也可以是辅小区组(SCG)，小区可以为主小区(PCell)，主辅小区(PSCell)以及辅小区(SCell)之一。
在本公开中，小区组可以指代主小区，主辅小区，辅小区中的任意一种或多种。
进一步可以理解的是，本公开中涉及的小区组激活处理包括小区组激活处理，也可以包括小区组去激活处理，还可以包括小区组激活处理和小区组去激活处理。
在本公开中，小区组激活处理也可以包括小区激活处理。
本公开中涉及的小区激活处理包括小区激活处理，也可以包括小区去激活处理，还可以包括小区激活处理和小区去激活处理。

其中，本公开实施例中用于小区组选择性激活的配置信息可以包括：配置ID以及目标小区的配置或目标小区组的配置。可选的，小区组激活的配置信息还可以包括触发条件(也可以称为执行条件、激活条件)。
其中，本公开实施例中服务小区组是当前激活的小区组。当选择的小区组被成功激活后则为服务小区组。当前服务小区组在被激活前可以是“待激活小区组”。服务小区组被去激活后可以是待激活的小区组。
本公开实施例提供的一种通信方法中，终端执行选择的小区组的激活，和/或，服务小区组的去激活，包括以下情况中的一种或多种：

情况二：响应于存在服务小区组，更改当前服务小区组为选择的小区组。

需要说明的是，本公开实施例中终端不存在服务小区组，一方面可以是不存在服务辅小区组或未激活任一辅小区组，此种情况下，终端可以基于主小区组与网络设备进行交互并进行相应信息的获取，例如通过主小区组进行接收用于小区组选择性激活的配置信息。另一方面，本公开实施例中终端不存在服务小区组也可以是不存在服务主小区组或未激活任一主小区组，此种情况下，用于小区组选择性激活的配置信息可以是在存在服务小区组的情况下提前进行获取的。
其中，本公开实施例中以终端激活某个小区组/小区为例进行说明。
本公开实施例提供的一种通信方法中，终端采用如下方式的一种或多种方式进行通 信：
A：响应于触发终端激活某个小区组/小区(此需要进行激活的小区组/小区被称为被选择的小区组/小区)，若此时存在激活的小区组/小区，则可以执行以下A\B\C中的一种或多种：

本公开实施例提供的通信方法中，另一方面在小区组选择性激活中，仅存在一个“待激活小区组/小区”为激活状态，即终端只能同时激活一个或多个小区组/小区。
