技术领域
本公开涉及通信技术领域，特别是指一种重复传输的激活/去激活方法、基站、终端及装置。
背景技术
5G NR(New Radio新空口)系统主要支持三类业务：eMBB(enhanced Mobile Broadband，增强型宽带通信)；mMTC(massive Machine Type Communications，大量机器类型通信)；URLLC(Ultra-Reliable and Low Latency Communications，高可靠低时延通信)。
对于URLLC，由于其对时延和可靠性都有比较高的要求，目前3GPP给出的一种解决方案是引入重复传输机制，即通过多个路径传输相同的PDCP(Packet Data Convergence Protocol，分组数据汇聚协议)层PDU(Protocol Data Unit，协议数据单元)，通过多路传输增益提升传输可靠性，并降低传输时延。PDCP重复传输引入后不仅适用于URLLC业务，也适用于其他业务。
CA(Carrier aggregation，载波聚合)和DC(Dual connectivity，双连接)下的重复传输的模型分别如图1和图2所示。PDCP层的一个无线承载(对应一个PDCP实体)，在RLC(Radio Link Control，无线链路控制协议)层通过多个逻辑信道(每个逻辑信道对应一个RLC实体)分别进行传输。如图1所示，对于CA模型，重复传输的无线承载对应的多个逻辑信道在MAC层由一个MAC实体进行处理，将来自不同RLC逻辑信道的数据分别映射到一个载波上不同的无线资源或者不同载波上进行传输。如图2所示，对于DC模型，重复承载(duplication RB)对应的多个逻辑信道分别映射到不同的MAC实体，自然可以将来自多个不同RLC逻辑信道的数据分别映射到不同无线资 源或者载波上进行传输。
目前重复传输机制是通过网络侧配置，即网络侧配置哪些承载(RB)可以进行重复传输，并对具体的RB(对应一个RB身份)进行对应的各层配置(如PDCP实体、RLC实体等)。然后网络侧用MAC层信令MAC CE(激活/去激活重复传输MAC CE)进行重复传输激活/去激活。网络部署中DC和CA配置一般的同时存在的，对于一个终端的承载，可能存在如图3所示的几种重复传输承载配置。DRB1和DRB4分别是MCG(主小区群，Master Cell Group)和SCG(辅小区群，Secondary Cell Group)下的CA重复传输，DRB2和DRB3分别是MCG和SCG下的DC重复传输。MCG和SCG分属不同的基站(5G基站)，即基站1和基站2，基站1和基站2都可以发送MAC CE对重复传输的承载进行激活和去激活。
综上，不同的网络节点都可以对终端发送激活/去激活重复传输MAC CE进行重复传输承载的激活和去激活，不同网络节点在发送激活/去激活重复传输MAC CE的时候不需要协同，其发送的内容可能是矛盾的，目前没有方法解决不同网络节点发送不同的激活/去激活重复传输MAC CE时，终端如何正确操作的问题。

本公开的上述实施例中，基站侧只对本基站下允许进行重复传输的承载的重复传输进行激活/去激活指示，例如第一基站下允许进行重复传输的承载包括：DRB1和DRB2，则第一基站的激活/去激活重复传输MAC CE的预设字段有2个比特位(设为第1个bit位和第2个bit位)与DRB1和DRB2分别存在对应关系；其中，第1个bit位用于对DRB1进行激活/去激活指示，第2个bit位用于对DRB2进行激活/去激活指示。需要说明的是，第一基站的激活/去激活重复传输MAC CE的预设字段的其他bit位的作用在此不作限定，但是该第一基站的激活/去激活重复传输MAC CE的预设字段的其他bit位不被用于对其他基站下允许进行重复传输的承载进行激活/去激活的有效指示。该DRB具体指数据承载。
进一步需要说明的是，允许进行重复传输的承载RB可以为数据承载DRB，也可以为信令承载SRB，在此不作具体限定。本公开的下述实施例中为了描述的清楚，允许进行重复传输的承载RB均假设为数据承载DRB。
由于基站侧只对本基站下允许进行重复传输的承载的重复传输进行激活/去激活指示，则终端侧接收到激活/去激活重复传输MAC CE后，根据发送该激活/去激活重复传输MAC CE的基站确定预设字段的有效bit位，从而仅激活/去激活发送激活/去激活重复传输MAC CE的基站指示的承载；即本基站发送的激活/去激活重复传输MAC CE不能激活/去激活其他基站下的承载， 从而避免了基站侧和终端侧对于激活/去激活重复传输MAC CE的误解，有效实现了重复传输。
进一步的，本公开的上述实施例中，步骤41包括：
所述第一基站对第一基站的激活/去激活重复传输MAC CE的预设字段的比特位和所述第一基站下允许进行重复传输的承载之间的对应关系进行配置；
所述第一基站将配置的对应关系发送给所述终端。
具体的，基站对本基站下允许进行重复传输的承载和本基站的激活/去激活重复传输MAC CE的预设字段的比特位之间的对应关系进行配置。例如第一基站下允许进行重复传输的承载包括：DRB1和DRB2，则第一基站的激活/去激活重复传输MAC CE的预设字段有2个比特位(设为第1个bit位和第2个bit位)与DRB1和DRB2分别存在对应关系；其中，第1个bit位用于对DRB1进行激活/去激活指示，第2个bit位用于对DRB2进行激活/去激活指示。
进一步的，本公开的上述实施例中，所述方法还包括：
所述第一基站对与终端连接的其他基站的激活/去激活重复传输MAC CE的预设字段的比特位和所述其他基站下允许进行重复传输的承载之间的对应关系进行配置；
所述第一基站将该配置的对应关系发送给终端；和/或，所述第一基站将该配置的对应关系发送给对应基站。
具体的，基站不仅可以对本基站下允许进行重复传输的承载和本基站的激活/去激活重复传输MAC CE的预设字段的比特位之间的对应关系进行配置，还可以对其他基站下允许进行重复传输的承载和其他基站的激活/去激活重复传输MAC侧的预设字段的比特位之间的对应关系进行配置。
例如其他基站(设为第二基站)下允许进行重复传输的承载包括：DRB3和DRB4，则第一基站为第二基站的激活/去激活重复传输MAC CE的预设字段的2个比特位(设为第1个bit位和第2个bit位)与DRB3和DRB4对应关系进行配置；其中，第一基站配置预设字段的第1个bit位用于对DRB3进行激活/去激活指示，第2个bit位用于对DRB4进行激活/去激活指示。
需要说明的是，第二基站的激活/去激活重复传输MAC CE的预设字段的比特位和所述第二基站下允许进行重复传输的承载之间的对应关系也可以由第二基站自身进行配置，在此不作具体限定。而第一基站的激活/去激活重复传输MAC CE的预设字段的比特位和所述第一基站下允许进行重复传输的承载之间的对应关系也可以由其他基站进行，在此也不作具体限定。
本公开的上述实施例提供3种实现基站传输激活/去激活重复传输MAC CE的方式；具体的，
方式1：第一基站的激活/去激活重复传输MAC CE的预设字段和与所述终端连接的其他基站的激活/去激活重复传输MAC CE的预设字段具有相同结构；
所述具有相同结构的激活/去激活重复传输MAC CE的预设字段的比特位与所述终端下允许进行重复传输的全部承载存在对应关系。
由于第一基站和其他基站均为与终端连接的连接，即与终端连接的所有基站发送给该终端的激活/去激活重复传输MAC CE的预设字段的结构相同，则该激活/去激活重复传输MAC CE的预设字段的比特位与所述终端下允许进行重复传输的全部承载存在对应关系。终端下允许进行重复传输的全部承载包含第一基站下允许进行重复传输的承载。
例如终端A分别与基站B、基站C和基站D连接，则终端A下允许进行重复传输的全部承载包括：终端A与基站B之间允许进行重复传输的承载、终端A与基站C之间允许进行重复传输的承载以及终端A与基站D之间允许进行重复传输的承载。
综上，方式1中，不同基站(网络侧节点)采用相同的激活/去激活重复传输MAC CE配置，即该MAC CE中bitmap的bit位与承载RB的对应关系在不同基站中是一样的(虽然部分RB只在特定基站下传输)。
如图5所示，基站1下配置了DRB1和DRB2的重复传输，基站2下配置了DRB2和DRB3的重复传输。激活/去激活重复传输MAC CE的格式在基站1和基站2下是一致的，即采用相同的bitmap指示方式，采用前3个bit分别指示DRB1、DRB2和DRB3。当基站1发送激活/去激活重复传输MAC CE时，终端只生效DRB1和DRB2对应bit位的指示，激活或去激活对应DRB 的重复传输；当基站2发送激活/去激活重复传输MAC CE时，终端只生效DRB2和DRB3对应bit位的指示，激活或去激活对应DRB的重复传输。图中仅展示激活/去激活重复传输MAC CE中的bitmap的有效位。
进一步的，图5中相同结构的激活/去激活重复传输MAC CE的预设字段的比特位与所述终端下允许进行重复传输的全部承载存在对应关系可以由基站1配置，或者由基站2配置，或者由基站1和基站2共同配置。
由一个基站对激活/去激活重复传输MAC CE中bitmap的bit位与RB的对应关系进行配置。例如，图中可以由基站1将该MAC CE中bitmap的前3个bit位配置为对应DRB1、DRB2、DRB3。
或者，由多个基站对激活/去激活重复传输MAC CE的bitmap的bit位与RB的对应关系进行配置。例如，图中可以由基站1将该MAC CE中bitmap的前2个bit位配置为对应DRB1、DRB2，由基站2将该MAC CE中bitmap的第3个bit位配置为对应DRB3。
方式2：第一基站的激活/去激活重复传输MAC CE的预设字段和与所述终端连接的其他基站的激活/去激活重复传输MAC CE的预设字段具有相互独立的结构；
所述第一基站的激活/去激活重复传输MAC CE的预设字段的比特位与所述第一基站下允许进行重复传输的承载存在对应关系；
所述其他基站的激活/去激活重复传输MAC CE的预设字段的比特位与所述其他基站下允许进行重复传输的承载存在对应关系。
具体的，不同基站采用各自独立的激活/去激活重复传输MAC CE配置，即该MAC CE中bitmap的bit位与RB的对应关系根据各个基站配置的RB各不相同。本基站下无效的DRB不会在激活/去激活重复传输MAC CE中指示。如图6所示，基站1下配置了DRB1和DRB2的重复传输，基站2下配置了DRB2和DRB3的重复传输。激活/去激活重复传输MAC CE的格式在基站1和基站2下是不一致的。当基站1发送激活/去激活重复传输MAC CE时，该MAC CE前两个bit分别指示DRB1和DRB2，终端激活或去激活对应DRB的重复传输；当基站2发送激活/去激活重复传输MAC CE时，该MAC CE前两个bit分别指示DRB2和DRB3，终端激活或去激活对应DRB的重复传 输；图中仅展示激活/去激活重复传输MAC CE中的bitmap的有效位。
进一步的，图6中相互独立的不同基站的激活/去激活重复传输MAC CE的预设字段的结构可以由基站1配置，或者由基站2配置，或者由基站1和基站2共同配置。
由一个基站对激活/去激活重复传输MAC CE中bitmap各个bit位与RB的对应关系进行配置，本实施例中，针对不同的小区群CG(主小区群MCG或辅小区群SCG)，各自进行不同的对应关系配置。例如，图6可以由基站1配置基站1下激活/去激活重复传输MAC CE中bitmap前2个bit位对应DRB1和DRB2；且由基站1配置基站2下激活/去激活重复传输MAC CE中bitmap前2个bit位对应DRB2和DRB3。
或者，由多个基站对激活/去激活重复传输MAC CE中bitmap各个bit位与RB的对应关系进行配置，本实施例中，由基站1对基站1下激活/去激活重复传输MAC CE进行配置，该MAC CE中bitmap前2个bit位对应DRB1和DRB2；而由基站2对基站2下激活/去激活重复传输MAC CE进行配置，该MAC CE中bitmap前2个bit位对应DRB2和DRB3。
方式3：第一基站的激活/去激活重复传输MAC CE的预设字段和与所述终端连接的其他基站的激活/去激活重复传输MAC CE的预设字段具有相互独立的结构；
所述第一基站的激活/去激活重复传输MAC CE的预设字段的比特位与只在第一基站下允许进行重复传输的承载存在对应关系；以及，
所述第一基站的激活/去激活重复传输MAC CE的预设字段的比特位与在第一基站下允许进行重复传输的特定承载存在对应关系；其中，所述特定承载是以双连接方式或多连接方式进行重复传输，且所述特定承载的主基站为所述第一基站。具体的，该特定承载的PDCP层所位于的基站则为该特定承载的主基站。
具体的，不同基站采用各自独立的激活/去激活重复传输MAC CE配置，即该MAC CE中bitmap各个bit位与RB的对应关系根据各个基站配置的RB各不相同，同时对于双连接DC或多连接MC的RB(即可以通过两个或多个基站传输的允许进行重复传输的RB)，只有一个主基站可以进行激活或去激 活重复传输的指示。
本基站下无效的RB不会在激活/去激活重复传输MAC CE中指示。如图7所示，基站1下配置了DRB1和DRB2的重复传输，基站2下配置了DRB2和DRB3的重复传输，但只能由主基站(即基站1)激活/去激活DRB2的重复传输。激活/去激活重复传输MAC CE的格式在基站1和基站2下是不一致的。当基站1发送激活/去激活重复传输MAC CE时，该MAC CE前两个bit分别指示DRB1和DRB2，终端激活或去激活对应DRB的重复传输；当基站2发送激活/去激活重复传输MAC CE时，该MAC CE第一个bit指示DRB3，终端激活或去激活对应DRB的重复传输。图中仅展示激活/去激活重复传输MAC CE中的bitmap的有效位。
进一步的，图7中相互独立的不同基站的激活/去激活重复传输MAC CE的预设字段的结构可以由基站1配置，或者由基站2配置，或者由基站1和基站2共同配置。
由一个基站对激活/去激活重复传输MAC CE中bitmap各个bit位与RB的对应关系进行配置，本实施例中，针对不同的小区群CG(主小区群MCG或辅小区群SCG)，各自进行不同的对应关系配置。例如，图7可以由基站1配置基站1下激活/去激活重复传输MAC CE中bitmap前2个bit位对应DRB1和DRB2；由基站1配置基站2下激活/去激活重复传输MAC CE中bitmap第1个bit位对应DRB3。在本实施例中，DRB2是双连接RB，只能由一个基站(本实施例中为基站1)进行重复传输激活或去激活，基站2无法对其进行重复传输激活/去激活。
或者，由多个基站对激活/去激活重复传输MAC CE中bitmap各个bit位与RB的对应关系进行配置，本实施例中，由基站1对基站1下激活/去激活重复传输MAC CE进行配置，该MAC CE中bitmap前2个bit位对应DRB1和DRB2；由基站2对基站2下激活/去激活重复传输MAC CE进行配置，该MAC CE中bitmap第1个bit位对应DRB3。在本实施例中，DRB2是双连接RB，只能由一个基站(本实施例中为基站1)进行重复传输激活或去激活，基站2无法对其进行重复传输激活/去激活。
综上，本公开的上述实施例提供的重复传输的激活/去激活方法中，由基 站预先配置允许进行重复传输的承载与激活/去激活重复传输MAC CE的预设字段的比特位的对应关系并将配置的对应关系发送给终端，且基站侧只对本基站下允许进行重复传输的承载的重复传输进行激活/去激活指示，使得终端在与多个基站连接时，可以正确接收和实现对不同类型承载的重复传输激活/去激活，从而有效实现重复传输，避免网络侧和终端侧的误解导致操作错误的问题。
如图8所示，本公开实施例还提供一种重复传输的激活/去激活方法，应用于终端，所述终端与多个基站连接，所述方法包括：
步骤81，确定第一基站下允许进行重复传输的承载与所述第一基站的激活/去激活重复传输介质访问控制层控制消息MAC CE的预设字段的比特位的对应关系；所述预设字段用于对允许重复传输的承载进行激活/去激活重复传输指示。
本步骤中，预设字段具体为激活/去激活重复传输MAC CE中的bitmap字段；bitmap字段一般为8bit，一般最多可用于指示8个承载的激活/去激活；需要说明的是，bitmap字段可设置为可扩展字段，则基站可根据其具体需求扩展bitmap字段的大小，从而扩展能够指示的承载的数量。
步骤82，若接收到第一基站发送的激活/去激活重复传输MAC CE，根据所述对应关系，解析所述第一基站的激活/去激活重复传输MAC CE的预设字段中与第一基站下允许进行重复传输的承载对应的比特位；
步骤83，根据所述比特位的指示，确定激活/去激活对应承载的重复传输。
本公开的上述实施例中，终端预先接收由基站侧配置的允许进行重复传输的承载与激活/去激活重复传输MAC CE的预设字段的比特位的对应关系，从而在接收到激活/去激活重复传输MAC CE时，根据发送该激活/去激活重复传输MAC CE的基站，以及该基站下激活/去激活重复传输MAC CE的比特位和承载的对应关系激活/去激活对应承载的重复传输。
由于终端能够预先根据基站配置的对应关系确定某一基站发送的激活/去激活重复传输MAC CE的预设字段的有效bit位，从而仅解析其有效bit位对与其对应的承载的进行激活/去激活，且由于基站侧仅在有效bit位上对本基站下允许进行重复传输的承载的重复传输进行激活/去激活指示，从而避免 了基站侧和终端侧对于激活/去激活重复传输MAC CE的误解，有效实现了重复传输。
进一步的，本公开的上述实施例中步骤81包括：
接收第一基站配置的第一基站的激活/去激活重复传输MAC CE的预设字段的比特位和所述第一基站下允许进行重复传输的承载之间的对应关系。
具体的，基站对本基站下允许进行重复传输的承载和本基站的激活/去激活重复传输MAC CE的预设字段的比特位之间的对应关系进行配置。例如第一基站下允许进行重复传输的承载包括：DRB1和DRB2，则第一基站的激活/去激活重复传输MAC CE的预设字段有2个比特位(设为第1个bit位和第2个bit位)与DRB1和DRB2分别存在对应关系；其中，第1个bit位用于对DRB1进行激活/去激活指示，第2个bit位用于对DRB2进行激活/去激活指示。
进一步的，本公开的上述实施例中，所述方法还包括：
接收第一基站配置的与终端连接的其他基站的激活/去激活重复传输MAC CE的预设字段的比特位和所述其他基站下允许进行重复传输的承载之间的对应关系。
具体的，基站不仅可以对本基站下允许进行重复传输的承载和本基站的激活/去激活重复传输MAC CE的预设字段的比特位之间的对应关系进行配置，还可以对其他基站下允许进行重复传输的承载和其他基站的激活/去激活重复传输MAC侧的预设字段的比特位之间的对应关系进行配置。
例如其他基站(设为第二基站)下允许进行重复传输的承载包括：DRB3和DRB4，则第一基站为第二基站的激活/去激活重复传输MAC CE的预设字段的2个比特位(设为第1个bit位和第2个bit位)与DRB3和DRB4对应关系进行配置；其中，第一基站配置预设字段的第1个bit位用于对DRB3进行激活/去激活指示，第2个bit位用于对DRB4进行激活/去激活指示。
需要说明的是，第二基站的激活/去激活重复传输MAC CE的预设字段的比特位和所述第二基站下允许进行重复传输的承载之间的对应关系也可以由第二基站自身进行配置，在此不作具体限定。而第一基站的激活/去激活重复传输MAC CE的预设字段的比特位和所述第一基站下允许进行重复传输的承 载之间的对应关系也可以由其他基站进行，在此也不作具体限定。
进一步的，本公开的上述实施例中所述方法还包括：
若接收到其他基站发送的激活/去激活重复传输MAC CE，根据所述对应关系，解析所述其他基站的激活/去激活重复传输MAC CE的预设字段中与所述其他基站下允许进行重复传输的承载对应的比特位；
根据所述比特位的指示，确定激活/去激活对应承载的重复传输。
具体的，终端接收到哪个基站发送的激活/去激活重复传输MAC CE，则根据基站预先配置的该基站的激活/去激活重复传输MAC CE的预设字段的比特位和该基站下允许进行重复传输的承载之间的对应关系来确定该基站发送的激活/去激活重复传输MAC CE的有效bit位，从而解析有效bit位，最终实现对相应承载的重复传输的激活/去激活。
本公开的上述实施例提供3种实现基站传输激活/去激活重复传输MAC CE的方式；具体的，
方式1：第一基站的激活/去激活重复传输MAC CE的预设字段和与所述终端连接的其他基站的激活/去激活重复传输MAC CE的预设字段具有相同结构；
所述具有相同结构的激活/去激活重复传输MAC CE的预设字段的比特位与所述终端下允许进行重复传输的全部承载存在对应关系。
由于第一基站和其他基站均为与终端连接的连接，即与终端连接的所有基站发送给该终端的激活/去激活重复传输MAC CE的预设字段的结构相同，则该激活/去激活重复传输MAC CE的预设字段的比特位与所述终端下允许进行重复传输的全部承载存在对应关系。终端下允许进行重复传输的全部承载包含第一基站下允许进行重复传输的承载。
例如终端A分别与基站B、基站C和基站D连接，则终端A下允许进行重复传输的全部承载包括：终端A与基站B之间允许进行重复传输的承载、终端A与基站C之间允许进行重复传输的承载以及终端A与基站D之间允许进行重复传输的承载。
方式1中激活/去激活重复传输MAC CE的预设字段的配置在基站侧的方法部分已经进行详细描述，在此不作重复说明。承接上例，终端侧的步骤包 括：
接收并生效基站侧发送的激活/去激活重复传输MAC CE中bitmap各个bit位与RB的对应关系的配置。例如，图5中可以由基站1将该MAC CE中bitmap的前3个bit位配置为对应DRB1、DRB2、DRB3。再例如图5中可以由基站1将该MAC CE中bitmap的前2个bit位配置为对应DRB1、DRB2，由基站2将该MAC CE中bitmap的第3个bit位配置为对应DRB3。
接收基站侧发送的激活/去激活重复传输MAC CE，根据对应bit位的指示激活或去激活对应RB的重复传输。如果基站1发送激活/去激活重复传输MAC CE，终端只根据DRB1和DRB2对应bit位(第1、2bit)的指示，对DRB1和DRB2进行重复传输激活或去激活，忽略该MAC CE中bitmap的第3个bit位；如果基站2发送激活/去激活重复传输MAC CE，终端只根据DRB2和DRB3对应bit位(第2、3bit)的指示，对DRB2和DRB3进行重复传输激活或去激活，忽略该MAC CE中bitmap的第1个bit位。
方式2：第一基站的激活/去激活重复传输MAC CE的预设字段和与所述终端连接的其他基站的激活/去激活重复传输MAC CE的预设字段具有相互独立的结构；
所述第一基站的激活/去激活重复传输MAC CE的预设字段的比特位与所述第一基站下允许进行重复传输存在对应关系；
所述其他基站的激活/去激活重复传输MAC CE的预设字段的比特位与所述其他基站下允许进行重复传输的承载存在对应关系。
具体的，不同基站采用各自独立的激活/去激活重复传输MAC CE配置，即该MAC CE中bitmap的bit位与RB的对应关系根据各个基站配置的RB各不相同。本基站下无效的DRB不会在激活/去激活重复传输MAC CE中指示。方式2中激活/去激活重复传输MAC CE的预设字段的配置在基站侧的方法部分已经进行详细描述，在此不作重复说明。承接上例，终端侧的步骤包括：
接收并生效基站侧发送的激活/去激活重复传输MAC CE中bitmap各个bit位与RB的对应关系的配置。例如，图6中由基站1分别配置基站1和基站2下的激活/去激活重复传输MAC CE中bitmap与RB的对应关系，基站1 下激活/去激活重复传输MAC CE中bitmap前2个bit位对应DRB1和DRB2；基站2下激活/去激活重复传输MAC CE中bitmap前2个bit位对应DRB2和DRB3。再例如，例如，图6中由基站1对基站1下激活/去激活重复传输MAC CE进行配置，该MAC CE中bitmap前2个bit位对应DRB1和DRB2；由基站2对基站2下激活/去激活重复传输MAC CE进行配置，该MAC CE中bitmap前2个bit位对应DRB2和DRB3。
接收基站侧发送的激活/去激活重复传输MAC CE，根据对应bit位的指示激活或去激活对应RB的重复传输。如果基站1发送激活/去激活重复传输MAC CE，终端只根据DRB1和DRB2对应bit位(第1、2bit)的指示，对DRB1和DRB2进行重复传输激活或去激活；如果基站2发送激活/去激活重复传输MAC CE，终端只根据DRB2和DRB3对应bit位(第1、2bit)的指示，对DRB2和DRB3进行重复传输激活或去激活。
方式3：第一基站的激活/去激活重复传输MAC CE的预设字段和与所述终端连接的其他基站的激活/去激活重复传输MAC CE的预设字段具有相互独立的结构；
所述第一基站的激活/去激活重复传输MAC CE的预设字段的比特位与只在第一基站下允许进行重复传输的承载存在对应关系；以及，
所述第一基站的激活/去激活重复传输MAC CE的预设字段的比特位与在第一基站下允许进行重复传输的特定承载存在对应关系；其中，所述特定承载是以双连接方式或多连接方式进行重复传输，且所述特定承载的主基站为所述第一基站。具体的，该特定承载的PDCP层所位于的基站则为该特定承载的主基站。
具体的，不同基站采用各自独立的激活/去激活重复传输MAC CE配置，即该MAC CE中bitmap各个bit位与RB的对应关系根据各个基站配置的RB各不相同，同时对于双连接DC或多连接MC的RB(即可以通过两个或多个基站传输的允许进行重复传输的RB)，只有一个主基站可以进行激活或去激活重复传输的指示。
方式3中激活/去激活重复传输MAC CE的预设字段的配置在基站侧的方法部分已经进行详细描述，在此不作重复说明。承接上例，终端侧的步骤包 括：
步骤1：接收并生效基站侧发送的激活/去激活重复传输MAC CE中bitmap各个bit位与RB的对应关系的配置。例如，图7中由基站1分别配置基站1和基站2下的激活/去激活重复传输MAC CE中bitmap与RB的对应关系，基站1下激活/去激活重复传输MAC CE中bitmap前2个bit位对应DRB1和DRB2；基站2下激活/去激活重复传输MAC CE中bitmap第1个bit位对应DRB3。再例如，例如，图7中由基站1对基站1下激活/去激活重复传输MAC CE进行配置，该MAC CE中bitmap前2个bit位对应DRB1和DRB2；由基站2对基站2下激活/去激活重复传输MAC CE进行配置，该MAC CE中bitmap第1个bit位对应DRB3。
步骤2：接收基站侧发送的激活/去激活重复传输MAC CE，根据对应bit位的指示激活或去激活对应RB的重复传输。如果基站1发送激活/去激活重复传输MAC CE，终端只根据DRB1和DRB2对应bit位(第1、2bit)的指示，对DRB1和DRB2进行重复传输激活或去激活；如果基站2发送激活/去激活重复传输MAC CE，终端只根据DRB3对应bit位(第1bit)的指示，对DRB3进行重复传输激活或去激活。
综上，本公开的上述实施例中由基站预先配置允许进行重复传输的承载与激活/去激活重复传输MAC CE的预设字段的比特位的对应关系并将配置的对应关系发送给终端，终端根据发送激活/去激活重复传输MAC CE的基站以及预先配置的对应关系激活/去激活对应承载的重复传输；使得终端在与多个基站连接时，可以正确接收和实现对不同类型承载的重复传输激活/去激活，从而有效实现重复传输，避免网络侧和终端侧的误解导致操作错误的问题。
