具体实施方式
为了更清楚地说明本公开实施例的技术方案，下面将对本公开实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
首先，对本公开实施例中所涉及的一些概念进行解释说明。
1、包数据汇聚协议(Packet Data Convergence Protocol，PDCP)数据复制(即PDCP duplication)发送介绍
新空口(New Radio，NR)中，为提高数据传输的可靠性，引入了PDCP duplication功能。网络侧配置终端比如用户设备(User Equipment，UE)的无线承载(Radio Bearer，RB)对应的PDCP层是否要将PDCP实体的数据复制后，将复制的数据分别通过两条(或多条)不同的传输路径(如两个不同的无线链路控制(Radio Link Control，RLC)实体)进行发送，不同RLC实体对应不同的逻辑信道。
PDCP数据复制功能可以通过媒体接入控制层控制信令(Medium Access Control Control Element，MAC CE)指示是否启动(即激活)还是停止(即 去激活)。网络侧在配置RB的PDCP复制数据功能时，可以配置该功能是否在配置后立即开启，即不需要MAC CE信令再额外激活。
其中，多条传输路径(可简称为路径)中，1条路径为主路径(primary leg)，该主路径一直处于激活状态(即，一直可以用于数据发送，而不能通过MAC CE指定激活或去激活)。UE的PDCP Control PDU(Protocol Data Unit，协议数据单元)不进行复制，且只能通过主路径进行发送。UE的PDCP data PDU在复制激活时进行复制，且复制的数据包只能通过不同的路径发送。
2、PDCP数据复制功能的承载类型
在5G系统中由于采用了双连接(Dual Connectivity，DC)架构(包括两个小区组，即主小区组(Master Cell Group，MCG)和辅小区组(Secondary Cell Group，SCG))，MCG对应于网络侧的主节点(Master Node，MN)，SCG对应于网络侧的辅节点(secondary node，SN)，因此PDCP数据复制功能的承载类型包括图1和图2所示的两种：
A11，分离承载(Split bearer)：该承载对应的PDCP实体在1个小区组，对应的2个(或多个)RLC和2个(或多个)MAC在不同的小区组。
A12，复制承载(Duplicate bearer)：该承载对应的1个PDCP实体、2个(或多个)RLC实体和1个MAC实体在1个小区组。
其中，当Split bearer采用PDCP数据复制功能时，若PDCP数据复制功能去激活，则该Split bearer可回退到DC split bearer工作模式。DC split bearer工作模式下，UE获取网络侧配置的缓存数据门限值(DataSplitThreshold)；如果PDCP数据量和/或“RLC层缓存的用于初始传输的数据量”大于或等于该门限值，则UE判定PDCP层的数据通过主RLC实体(即主传输路径，也可称为主路径)和辅RLC实体(即辅传输路径，也可称为辅路径)发送；如果PDCP数据量和/或“RLC层缓存的用于初始传输的数据量”小于该门限值，则UE判定PDCP层的数据通过主RLC实体发送。
3、多路径PDCP数据复制(Multiple Leg PDCP Duplication)
如图3和图4所示，PDCP数据复制功能可以配置超过两条(如，3个)路径(如，1个PDCP实体对应3个以上的RLC实体)，而网络侧可选择去激活其中1条或多条路径(如，可以去激活1条路径，但仍有2条路径可以工 作。去激活的路径不用于数据的接收或发送)，而该PDCP数据复制功能仍然可以继续通过激活的路径使用。对于去激活的路径，终端不能通过对应逻辑信道发送数据；对于激活的路径，终端可以通过对应逻辑信道发送数据。而配置的多条路径可以仅属于1个MAC实体，也可以属于两个MAC实体。
本公开的一些实施例中，如果网络设备为终端的某无线承载配置了多条传输路径，则基于无线承载配置的多条传输路径是属于1个MAC实体还是属于多个MAC实体，可分为以下两个场景：
场景一，无线承载配置的多条传输路径属于1个MAC实体；
场景二，无线承载配置的多条传输路径属于多个MAC实体。
本公开的一些实施例中，根据网络设备配置(即网络侧配置)或协议约定，可确定PDCP数据复制功能去激活下的工作模式包括：DC工作模式和非DC工作模式。可理解的，上述场景一适用于非DC工作模式，而上述场景二既可适用于非DC工作模式，也可适用于DC工作模式。
下面结合实施例和附图对本公开进行详细说明。
请参见图1，图1是本公开的一些实施例提供的一种数据发送方法的流程图，该方法应用于终端，如图1所示，该方法包括如下步骤：
步骤501：在无线承载的PDCP数据复制功能由激活状态变为去激活状态时，确定无线承载可用的至少一条传输路径。
本实施例中，该无线承载可选为确定的某个无线承载。该无线承载可选为信令无线承载(Signaling Radio Bearer，SRB)，或者数据无线承载(Data Radio Bearer，DRB)。该无线承载可配置多条即超过2条传输路径(比如4条传输路径，包括各条传输路径分别对应的逻辑信道1、2、3和4)。网络设备(即网络侧)可为该无线承载配置PDCP数据复制功能。
可理解的，该无线承载的多条传输路径可以属于1个MAC实体(对应上述场景一)；也可以属于多个MAC实体(对应上述场景二)，比如4条传输路径时，传输路径1和2属于MCG MAC实体，传输路径3和4属于SCG MAC实体。
步骤502：利用所述至少一条传输路径，发送PDCP数据。
本实施例中，上述发送PDCP数据可以理解为终端的PDCP实体将数据 通过所述至少一条传输路径发送。
比如，上述场景一下，DRB1的PDCP数据复制功能由激活状态变为去激活状态，可用传输路径1(对应逻辑信道标识1)；则：UE的PDCP实体将数据通过传输路径1发送，UE的PDCP实体将PDCP的数据量信息通过传输路径1统计和上报给网络设备。
或者，上述场景一下，DRB1的PDCP数据复制功能由激活状态变为去激活状态，可用传输路径1(对应逻辑信道标识1)和传输路径2(对应逻辑信道标识2)；则：UE的PDCP实体将数据通过传输路径1和传输路径2发送，UE的PDCP实体将要通过传输路径1发送的PDCP数据的数据量信息通过传输路径1统计和上报给网络设备，UE的PDCP实体将要通过传输路径2发送的PDCP数据的数据量信息通过传输路径2统计和上报给网络设备。
又比如，上述场景二下，DRB2的PDCP数据复制功能由激活状态变为去激活状态，可用传输路径1(对应MCG逻辑信道标识1)；则：UE的PDCP实体将数据通过传输路径1发送，UE的PDCP实体将PDCP的数据量信息通过传输路径1统计和上报给网络设备。
或者，上述场景二下，DRB2的PDCP数据复制功能由激活状态变为去激活状态，可用传输路径1(对应MCG逻辑信道标识1)和传输路径3(对应SCG逻辑信道标识3)；则：UE的PDCP实体将数据通过传输路径1和传输路径3发送，UE的PDCP实体将要通过传输路径1发送的PDCP数据的数据量信息通过传输路径1统计和上报给网络设备，UE的PDCP实体将要通过传输路径3发送的PDCP数据的数据量信息通过传输路径3统计和上报给网络设备。
本公开的一些实施例的数据发送方法，可以在终端的某无线承载配置了PDCP数据复制功能，且该PDCP数据复制功能由激活状态变为去激活状态时，确定该无线承载可用的至少一条传输路径，并利用此至少一条传输路径发送PDCP数据，从而明确当某无线承载的PDCP数据复制功能去激活时，如何对该无线承载的数据进行发送，保证网络设备侧和终端侧对相应无线承载的数据收发方式理解一致，实现更可靠的数据传输。
本公开的一些实施例中，可选的，步骤501可包括：
根据以下至少一项，确定无线承载可用的至少一条传输路径；
第一配置信息；
从网络设备接收到的去激活信令；
其中，所述第一配置信息为所述无线承载的PDCP数据复制功能去激活后的配置信息，所述去激活信令用于指示所述无线承载的PDCP数据复制功能由激活状态变为去激活状态。
可理解的，所述第一配置信息可由协议约定或者网络设备配置。无线承载的PDCP数据复制功能在后续激活(即由去激活状态变为激活状态)时，可由网络设备通过MAC CE(Control Element，控制单元)进行激活，即由网络设备通过MAC CE向终端发送激活信令；或者，无线承载的PDCP数据复制功能在后续去激活(即由激活状态变为去激活状态)时，可由网络设备通过MAC CE进行去激活，即由网络设备通过MAC CE向终端发送激活信令。
这样，借助第一配置信息和/或去激活信令确定可用传输路径，可以让网络设备侧和终端侧对相应无线承载的数据收发方式理解一致，从而实现更可靠的数据传输。
可选的，所述第一配置信息可包括以下至少一项：
1)可用的至少一条传输路径的标识信息；即相应无线承载的PDCP数据复制功能去激活后可用的1条或多条传输路径的标识信息；此配置1)可适用于上述场景一和上述场景二。
比如，上述场景一下，可配置PDCP数据复制功能去激活时，UE用于PDCP数据发送的可用传输路径为：传输路径1(对应逻辑信道标识1)；或者，传输路径1(对应逻辑信道标识1)和传输路径2(对应逻辑信道标识2)。
又比如，上述场景二下，可配置PDCP数据复制功能去激活时，UE用于PDCP数据发送的可用传输路径为：传输路径1(对应MCG逻辑信道标识1)；或者，传输路径1(对应MCG逻辑信道标识1)和传输路径3(对应SCG逻辑信道标识3)。
2)无线承载在PDCP数据复制功能去激活后采用DC工作模式；即网络设备配置或者协议约定该无线承载的PDCP数据复制功能去激活后采用DC 工作模式；此配置2)适用于上述场景二。
基于此配置2)，终端可确定相应无线承载的PDCP数据复制功能去激活后采用DC工作模式。
进一步的，在所述第一配置信息包括无线承载在PDCP数据复制功能去激活后采用DC工作模式的前提下，所述第一配置信息还可包括：所述DC工作模式的配置信息。
其中，所述DC工作模式的配置信息包括以下任意一项：
1)用于DC工作模式的两条传输路径的标识信息。
比如，协议约定某RB的PDCP数据复制功能去激活时，UE采用DC工作模式，且该DC工作模式下，用于PDCP数据发送的传输路径为：传输路径1(对应MCG逻辑信道标识1)和传输路径3(对应SCG逻辑信道标识3)。其中，传输路径1可配置为主传输路径，传输路径3可配置为辅传输路径；或者，传输路径1可配置为辅传输路径，传输路径3可配置为主传输路径。
2)用于DC工作模式的主传输路径的标识信息；
比如，网络设备通过RRC消息配置DC工作模式的主传输路径为：传输路径1(对应MCG逻辑信道标识1)。某RB的PDCP数据复制功能在通过MAC CE去激活时，该MAC CE指示1个激活传输路径(对应SCG逻辑信道3)；则：UE可将该RB的主传输路径设置为传输路径1，辅传输路径设置为传输路径3。
3)用于DC工作模式的辅传输路径的标识信息。
比如，网络设备通过RRC消息配置DC工作模式的辅传输路径为：传输路径1(对应MCG逻辑信道标识1)。某RB的PDCP数据复制功能在通过MAC CE去激活时，该MAC CE指示1个激活传输路径(对应SCG逻辑信道3)；则：UE可将该RB的辅传输路径设置为传输路径1，主传输路径设置为传输路径3。
本公开的一些实施例中，可选的，用于去激活PDCP数据复制功能的去激活信令可指示以下任意一项：
1)无线承载的所有传输路径为去激活状态；即相应配置PDCP数据复制功能的无线承载的所有传输路径都为去激活状态；此指示项1)可适用于上 述场景一和上述场景二。
比如，DRB1配置了传输路径1、2、3和4(分别对应逻辑信道1、2、3和4)，则该去激活信令指示传输路径1、2、3和4都为去激活状态。
2)无线承载的第一传输路径为激活状态，其他传输路径为去激活状态；所述其他传输路径为所述无线承载的所有传输路径中除所述第一传输路径之外的传输路径；此指示项2)可适用于上述场景一和上述场景二。
其中，该第一传输路径具体为一条传输路径，即相应配置PDCP数据复制功能的无线承载仅一条传输路径为激活状态。
比如，DRB1配置了传输路径1、2、3和4(分别对应逻辑信道1、2、3和4)，则该去激活信令仅指示传输路径1为激活状态，其他传输路径(即传输路径2、3和4)为去激活状态。
3)两条传输路径，该两条传输路径是无线承载在PDCP数据复制功能去激活后的DC工作模式的传输路径；此指示项3)适用于上述场景二。
比如，DRB1配置了传输路径1、2、3和4(分别对应逻辑信道1、2、3和4)，则该去激活信令指示该DRB1的PDCP数据复制功能去激活后的DC工作模式的两条传输路径为：传输路径1(对应MCG逻辑信道标识1)和传输3(对应SCG逻辑信道标识3)。
可选的，终端根据第一配置信息和/或去激活信令，确定无线承载的可用的至少一条传输路径的过程可包括以下任意一项：
1)当所述去激活信令指示所述无线承载的所有传输路径为去激活状态时，终端根据所述第一配置信息包括的可用的至少一条传输路径的标识信息，确定所述至少一条传输路径。

或者，
将所述两条传输路径中的SCG的传输路径确定为主传输路径，和将所述两条传输路径中的MCG的传输路径确定为辅传输路径。
需说明的是，上述确定主传输路径和辅传输路径的方式可以由协议约定；也可以由网络设备配置，比如相应配置信息包括在上述的第一配置信息中，通过RRC消息配置；也可以由网络设备指示，比如借助上述去激活信令通过MAC CE指示。
可选的，步骤501之前，所述方法还包括：

其中，所述第二配置信息包括：所述无线承载的PDCP数据复制功能的初始状态；所述初始状态为激活状态和去激活状态中任意一者。所述第二配置信息可由协议约定或者网络设备配置。所述第二配置信息在由网络设备配置时，可由网络设备通过RRC消息发送给终端。
比如，对于初始状态为激活状态，UE接收到相应RRC消息(其包括的配置信息指示PDCP数据复制功能的初始状态为激活状态)后，立即激活相应RB的PDCP数据复制功能。
又比如，对于初始状态为去激活状态，UE接收到相应RRC消息(其包括的配置信息指示PDCP数据复制功能的初始状态为去激活状态)后，不激活相应RB的PDCP数据复制功能。
进一步的，所述第二配置信息还包括：所述初始状态为激活状态的配置信息(由协议约定或者网络设备配置)，或者，所述初始状态为去激活状态的配置信息(由协议约定或者网络设备配置)。
其中，所述初始状态为激活状态的配置信息包括：激活的多条传输路径的标识信息。

又比如，上述场景二下，可配置PDCP数据复制功能的初始状态为去激活状态时，UE用于PDCP数据发送的传输路径为：传输路径1(对应MCG逻辑信道标识1)；或者，传输路径1(对应MCG逻辑信道标识1)和传输路径3(对应MCG逻辑信道标识3)。
进一步的，在获取第二配置信息之后，所述方法还可包括：
根据所述第二配置信息，确定用于PDCP数据发送的传输路径。
这样，基于此确定的传输路径，终端可进行相应数据的发送。
比如，上述场景一下，DRB1初始状态为PDCP数据复制功能激活，配置了激活的传输路径1(对应逻辑信道标识1)和激活的传输路径2(对应逻辑信道标识2)；则：UE的PDCP实体将数据和复制数据分别通过传输路径1和传输路径2发送，UE的PDCP实体将PDCP的数据量信息分别通过传输路径1和传输路径2统计和上报给网络设备。
