应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
为便于理解本申请实施例的技术方案，以下对本申请实施例相关的技术方案进行说明。
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，为此第三代合作伙伴计划(3 rd Generation Partnership Project，3GPP)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 Communications，mMTC)。
一方面，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，例如室内，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。
在NR早期部署时，完整的NR覆盖很难获取，所以典型的网络覆盖是广域的LTE覆盖和NR的孤岛覆盖模式。而且大量的LTE部署在6GHz以下，可用于5G的6GHz以下频谱很少。所以NR必须研究6GHz以上的频谱应用，而高频段覆盖有限、信号衰落快。同时为了保护移动运营商前期在LTE投资，提出了LTE和NR之间紧密合作(tight interworking)的工作模式。
为了能够尽快实现5G网络部署和商业应用，3GPP在2017年12底前首先完成第一个5G版本，即E-UTRA和NR双连接(E-UTRA-NR Dual Connectivity，EN-DC)。在EN-DC中，LTE基站(eNB)作为主节点(Master Node，MN)，NR基站(gNB或en-gNB)作为辅节点(Secondary Node，SN)。其中MN主要负责RRC控制功能以及通向核心网的控制面；SN可以配置辅助的信令，例如SRB3，主要提供数据传输功能。
在R15后期，将支持其他双连接(Dual Connectivity，DC)模式，即NR和E-UTRA双连接(NR-E-UTRA Dual Connectivity，NE-DC)，5GC-EN-DC，NR DC。对于EN-DC，接入网络连接的核心网是演进型分组核心网(Evolved Packet Core network，EPC)，而其他DC模式连接的核心网是5G核心网(5G Core Network，5GC)。
在多RAT双连接(Multi-RAT Dual Connectivity，MR-DC)中，参照图2，承载类型分为MN初始的MCG承载(MN terminated MCG Bearer)、MN初始的SCG承载(MN terminated SCG Bearer)、MN初始的分流承载(MN terminated split Bearer)、SN初始的MCG承载(SN terminated MCG Bearer)、SN初始的SCG承载(SN terminated SCG Bearer)、SN初始的分流承载(SN terminated split Bearer)。其中，“MN初始的(MN terminated)”的意思是承载对应的分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)资源(即PDCP实体)位于MN侧，“SN初始的(SN terminated)”的意思是承载使用的PDCP资源位于SN侧。“MCG承载”的意思是承载使用的RLC/MAC/PHY资源位于MN侧，“SCG承载”的意思是承载使用的RLC/MAC/PHY资源位于SN侧，“分流承载”的意思是承载使用的RLC/MAC/PHY资源位于MN和SN侧。
为了满足工业以太网更严苛的数据传输可靠性要求，允许终端设备在PDCP层的复制传输功能处于激活态下，使用多于两条RLC传输链路(简称为路径或者腿(leg))进行数据包冗余传输的需求。允许网络为终端设备配置最多4条RLC传输链路用于同时传输复制的数据包。可以在载波聚合(CA)和载波聚合+双连接(CA+DC)场景下支持最多4条RLC传输链路的复制传输。
图3为CA场景下支持4条RLC传输链路的复制传输的4种情况，其中，4条RLC传输链路中的不同RLC传输链路对应不同的RLC实体，例如RLC1、RLC2、RLC3和RLC4分别对应路径1(即CC1)、路径2(即CC2)、路径3(即CC3)和路径4(即CC4)。这里，路径也即RLC传输链路，路径与成员载波(Component Carrier，CC)对应，从而可以实现CA功能。
CA+DC场景下的复制传输情况与CA类似，区别在于，激活复制传输功能的PDCP实体可以位于MN侧或者SN侧，也可以支持最多4条RLC传输链路的复制传输，4条RLC传输链路中的不同RLC传输链路对应不同的RLC实体，4个RLC实体可以分布在MN和SN侧，或者也可以全部分布在MN侧，或者也可以全部分布在SN侧。分布情况不同，RLC传输链路对应的承载类型就不同，具体可以参照前述图2相关的描述。
在具体实施中，网络可以通过RRC信令为终端设备配置与数据无线承载(Data Radio Bearer，DRB)相关的RLC传输链路，这里，DRB也可以简称为承载，承载类型可以参照前述图2相关的描述。对于承载进行复制 传输时，一个承载可以关联多条RLC传输链路，即有多个RLC实体对应的承载标识为同一个。此外，通过RRC信令可以配置主leg和用于复制传输的辅leg。需要说明的是，多条RLC传输链路也可以简称为多条leg或者多条路径，RRC信令可以配置这多条leg中哪一个leg为主leg，而其他leg均为辅leg。
当网络在承载对应的PDCP-config IE中配置了PDCP-duplication IE，则可视为网络已为终端设备配置了传输复制功能。至于传输复制功能的状态是否为激活的，需要进一步通过moreThanTwoRLC-r16中的duplicationState IE来确定。
在通过RRC信令对传输复制功能配置完成后，根据网络对信道情况的侦测或者根据终端设备反馈的信道情况，网络可以动态地为终端设备变换当前激活的RLC传输链路(具体为变换RCL传输链路的ID和/或数目)。针对网络最多为终端设备配置4条RLC传输链路进行数据包复制传输的需求，通过一个RLC激活/去激活MAC CE，用于动态地变换当前激活的RLC传输链路。参照图4，RLC激活/去激活MAC CE的净荷格式由DRB ID和相关的RLC激活状态标识位组成，由于4条RLC传输链路中只有3条辅leg，主leg始终保持在激活状态，因而只需要对这3条辅leg进行激活去激活指示。其中，RLC激活/去激活MAC CE中的DRB ID用于标识网络下发此MAC CE对应的目标承载。后续的比特位设置为0/1用于指示终端设备去激活/激活对应的RLC传输链路。需要说明的是，索引为0到2的RLC传输链路对应逻辑信道标识按升序排列，并遵从先MN再SN的原则。通过RLC激活/去激活MAC CE，网络可以快速指示终端设备用哪几个已配置的RLC传输链路用于给定承载的复制传输。需要说明的是，是否要使用复制传输，即是否要启用辅leg，可以取决于承载的业务量是否大于一定门限(如ul-DataSplitThreshold)。
为了支持终端设备的节能以及快速建立SCG，标准上同意支持dormancy SCG的概念，dormancy SCG意味着SCG中的所有小区处于dormancy状态，处于dormancy状态的小区不监听物理下行控制信道(PDCCH)，不执行数据的发送和接收，但是执行RRM，CSI测量以及波束管理等。所以如何支持dormancy SCG是个需要明确的问题。为此，提出了本申请实施例的以下技术方案。
需要说明的是，本申请实施例中对于“MCG侧”的描述也可以称为“MN侧”，对于“SCG侧”的描述也可以称为“SN侧”。
需要说明的是，本申请实施例中的主路径也可以称为主leg或者主RLC传输链路，本申请实施例中的辅路径也可以称为辅leg或者辅RLC传输链路。其中，不同的路径对应不同的RLC实体。主路径始终处于激活状态，因而主路径对应的RLC资源(也即RLC实体)被占用。辅路径处于激活状态时，该辅路径对应的RLC资源(也即RLC实体)被占用；辅路径处于去 激活状态时，该辅路径对应的RLC资源(也即RLC实体)不被占用。
需要说明的是，本申请实施例中的“路径在MCG侧”也可以理解为“路径对应的RLC资源位于MCG侧”。本申请实施例中的“路径在SCG侧”也可以理解为“路径对应的RLC资源位于SCG侧”。
需要说明的是，对于一个承载来说，其可以关联的路径的个数不限于4个，也可以是其他数目。承载关联的多条路径中有一条路径为主路径，而其他路径均为辅路径。承载的类型，可以根据多条路径对应的RLC资源的分布来确定，具体可以参照图2相关的描述。
图5是本申请实施例提供的控制SCG状态的方法的流程示意图，如图5所示，所述控制SCG状态的方法包括以下步骤：
步骤501：MN确定满足第一条件的情况下，所述MN触发辅小区组SCG进入去激活状态，所述第一条件用于表征所述SCG侧的资源不被占用。
可选地，还包括：步骤502：所述MN确定满足第二条件的情况下，所述MN触发SCG进入激活状态，所述第二条件用于表征所述SCG侧的资源被占用。
需要说明的是，本申请实施例对步骤501和步骤502的执行顺序不做限制。本申请实施例可以单独执行步骤501，也可以单独执行步骤502。
本申请实施例的技术方案应用于DC架构，DC中的主节点即为MN，DC中的辅节点即为SN，即MN和SN为DC的两个节点。MN侧的小区组称为MCG，SN侧的小区组称为SCG。本申请实施例对DC的类型不做限制，例如可以是MR-DC、EN-DC、NE-DC、NR-DC等等。
本申请实施例中，一方面，定义了去激活SCG的条件，即第一条件，所述第一条件用于表征所述SCG侧的资源不被占用。另一方面，定义了激活SCG的条件，即第二条件，所述第二条件用于表征所述SCG侧的资源被占用。MN确定满足第一条件的情况下，触发辅SCG进入去激活状态(也即suspend状态)；MN确定满足第二条件的情况下，触发SCG进入激活状态。以下对第一条件和第二条件进行说明。
