具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
在本申请中使用的术语“部件”、“模块”、“系统”等用于表示计算机相关的实体、硬件、固件、硬件和软件的组合、软件、或执行中的软件。例如，部件可以是但不限于，在处理器上运行的进程、处理器、对象、可执行文件、执行线程、程序和/或计算机。通过图示，在计算设备上运行的应用和计算设备都可以是部件。一个或多个部件可驻留在进程和/或执行线程中，部件可位于一个计算机上和/或分布在2个或更多个计算机之间。此外，这些部件可从在上面存储有各种数据结构的各种计算机可读介质执行。部件可例如根据具有一个或多个数据分组(例如来自与本地系统、分布式系统和/或网络间的另一部件交互的二个部件的数据，例如通过信号与其它系统交互的互联网)的信号通过本地和/或远程进程来通信。
应理解，本申请实施例中的方式、情况、类别以及实施例的划分仅是为了描述的方便，不应构成特别的限定，各种方式、类别、情况以及实施例中的特征在不矛盾的情况下可以相结合。
还应理解，在本申请的各实施例中，“第一”、“第二”、“第三”等仅是为了指代不同的对象，并不表示对指代的对象有其它限定。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、未来的第五代(5th Generation，5G)系统或新无线(New Radio，NR)等。
本申请的通信方法的执行主体(即，第一设备)可以是终端设备也可以是网络设备。
其中，终端设备也可以称为用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备可以是WLAN中的站点(STAION，ST)，可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路 (Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、车联网终端、电脑、膝上型计算机、手持式通信设备、手持式计算设备、卫星无线设备、无线调制解调器卡、电视机顶盒(set top box，STB)、用户驻地设备(customer premise equipment，CPE)和/或用于在无线系统上进行通信的其它设备以及下一代通信系统，例如，5G网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的终端设备等。
作为示例而非限定，在本申请实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
此外，在本申请实施例中，终端设备还可以是物联网(Internet of Things，IoT)系统中的终端设备，IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。
网络设备可以包括接入网设备或核心网设备。
其中，接入网设备可以是接入网设备等用于与移动设备通信的设备，接入网设备可以是WLAN中的接入点(Access Point，AP)，GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB，NB)，或者是新型无线系统(New Radio，NR)系统中的gNB，还可以是LTE中的演进型基站(Evolutional NodeB，eNB或eNodeB)，或者中继站或接入点，或者路边单元(Roadside Unit，RSU)，或者车载设备、可穿戴设备以及未来5G网络中的接入网设备或者未来演进的PLMN网络中的接入网设备等。
另外，在本申请实施例中，接入网设备为小区提供服务，终端设备通过该小区使用的传输资源(例如，时频资源，频率资源，或者，频谱资源)与接入网设备进行通信，该小区可以是接入网设备(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(Small cell)对应的基站，这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
此外，LTE系统或5G系统中的载波上可以同时有多个小区同频工作，在某些特殊场景下，也可以认为上述载波与小区的概念等同。例如在载波聚合(Carrier Aggregation，CA)场景下，当为UE配置辅载波时，会同时携带辅载波的载波索引和工作在该辅载波的辅小区的小区标识(Cell Indentify，Cell ID)，在这种情况下，可以认为载波与小区的概念等同，比如UE接入一个载波和接入一个小区是等同的。
此外，本申请实施例中的载波(carrier)与载波聚合(carrier aggregation)中的载波概念相同，还可以理解为频段(band)、子频段(sub-band)、BWP(Bandwidth part，部分带宽)、信道 (channel)、子信道(sub-channel)，或者一段频谱资源等，在频域上表现为一组子载波集合。不同的载波或频段可能有不同的中心频点；也可能有相同的中心频点，例如带宽不同但中心频点相同的频段。
核心网设备可以与多个接入网设备连接，用于控制接入网设备，并且，可以将从网络侧(例如，互联网)接收到的数据分发至接入网设备。
其中，以上列举的终端设备、接入网设备和核心网设备的功能和具体实现方式仅为示例性说明，本申请并未限定于此。
在本申请实施例中，终端设备或网络设备包括硬件层、运行在硬件层之上的操作系统层，以及运行在操作系统层上的应用层。该硬件层包括中央处理器(Central Processing Unit，CPU)、内存管理单元(Memory Management Unit，MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(Process)实现业务处理的计算机操作系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且，本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法进行通信即可，例如，本申请实施例提供的方法的执行主体可以是终端设备或网络设备，或者，是终端设备或网络设备中能够调用程序并执行程序的功能模块。
图1是适用于本申请的数据单元处理的方法的通信系统的示意图。如图1所示，该通信系统100包括网络设备102，网络设备102可包括多个天线例如，天线104、106、108、110、112和114。另外，网络设备102可附加地包括发射机链和接收机链，本领域普通技术人员可以理解，它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、编码器、解复用器或天线等)。
网络设备102可以与多个终端设备(例如终端设备116和终端设备122)通信。然而，可以理解，网络设备102可以与类似于终端设备116或122的任意数目的终端设备通信。终端设备116和122可以是，例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、PDA和/或用于在无线通信系统100上通信的任意其它适合设备。
如图1所示，终端设备116与天线112和114通信，其中天线112和114通过前向链路118向终端设备116发送信息，并通过反向链路120从终端设备116接收信息。此外，终端设备122与天线104和106通信，其中天线104和106通过前向链路124向终端设备122发送信息，并通过反向链路126从终端设备122接收信息。
例如，在FDD系统中，例如，前向链路118可利用与反向链路120所使用的不同频带，前向链路124可利用与反向链路126所使用的不同频带。
再例如，在TDD系统和全双工(full duplex)系统中，前向链路118和反向链路120可使用共同频带，前向链路124和反向链路126可使用共同频带。
被设计用于通信的每个天线(或者由多个天线组成的天线组)和/或区域称为网络设备102的扇区。例如，可将天线组设计为与网络设备102覆盖区域的扇区中的终端设备通信。在网络设备102通过前向链路118和124分别与终端设备116和122进行通信的过程中，网络设备102的发射天线可利用波束成形来改善前向链路118和124的信噪比。此外， 与网络设备通过单个天线向它所有的终端设备发送信号的方式相比，在网络设备102利用波束成形向相关覆盖区域中随机分散的终端设备116和122发送信号时，相邻小区中的移动设备会受到较少的干扰。
在给定时间，网络设备102、终端设备116或终端设备122可以是无线通信发送装置和/或无线通信接收装置。当发送数据时，无线通信发送装置可对数据进行编码以用于传输。具体地，无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中，传输块可被分段以产生多个码块。
此外，该通信系统100可以是PLMN网络或者设备与设备(device-to-device，D2D)网络或者机器与机器(machine to machine,M2M)网络或者其他网络，图1只是举例的简化示意图，网络中还可以包括其他网络设备，图1中未予以画出。
重复传输是5G NR中引入的新特性，通过在PDCP层生成两个相同的数据单元，向连接的两个RLC层传输。基于双连接的重复传输与当前的分裂承载的配置的协议栈架构相同，因此需要指示区分二者的配置。并且申请人发现，目前还不能向终端设备指出重复传输的初始状态，该初始状态可以理解为，终端设备接收到配置信息后，配置重复传输是否工作的状态。目前在5G的新空口中，没有指出如何指示配置了重复传输的承载的初始状态。
下面将结合具体的例子详细描述本申请实施例。应注意，这只是为了帮助本领域技术人员更好地理解本申请实施例，而非限制本申请实施例的范围。
图2是根据本申请实施例的通信方法的交互流程图。图2中的第一设备可以是图1中的任意一个终端设备，第二设备可以为基站。210，第二设备向第一设备发送第一消息，该第一消息用于指示该第一设备的承载的承载配置和该承载配置的初始状态，其中，该承载配置包括第一承载配置和/或第二承载配置。
应理解，在第二设备向第一设备发送第一消息之前，第二设备配置第一设备的承载的承载配置和该承载配置的初始状态。应理解，该初始状态为接收到该承载配置后配置的状态。
需要说明的是，第一设备的承载可以为数据无线承载，也可以为信令无线承载。承载配置中可以包括第一承载配置和第二承载配置，也可以包括第一承载配置、第二承载配置和第三承载配置。承载配置至少包括第一承载配置和第二承载配置。
其中，第一承载配置可以为配置重复传输duplication功能的承载，duplication为5G NR引入的新特性。duplication为了保障数据传输过程中的高可靠低时延的要求提出，即在PDCP层复制将要发送的数据单元，复制成两个数据单元分别在两条路径上发送。在未来技术中，duplicaition可以将一个数据单元复制成多个数据单元，在多条路径上发送。
第二承载配置可以为配置分裂split承载，split承载即为两条路径上传输不同的数据单元。在未来技术中，split承载也可以在两条或两条以上的路径传输不同的数据单元。
初始状态包括激活态和去激活态。以配置了两条路径的重复传输的承载为例进行说明，配置了重复传输的承载的激活态是指两条路径开始传输相同的数据单元；配置了重复传输的承载的去激活态是指两条路径中的仅有初始路径在工作。以配置了多条路径的重复传输的承载为例进行说明，初始状态的激活态和去激活态为每条路径的状态。
应理解，对于两条路径而言，重复承载即配置了重复传输的承载为PDCP层连接两个RLC层，并且配置了PDCP层可以将一个协议数据单元(Protocol Data Unit，PDU)复制成两个相同的PDU，具有向两个RLC层传输功能的承载。分裂承载即split承载为PDCP层连接两个RLC，并且PDCP层向两个RLC传输不同的PDU。向哪个RLC层传输，可以根据配置门限进行选择。
需要说明的是，初始路径(Primary Path)为第一设备配置该第一承载或者该第二承载的路径。例如，该第一消息包括指示该初始路径的指示标识。在本申请的实施例的一种可能的实现方式中，该初始路径始终处于激活状态或工作状态。在本申请的实施例的另一种可能的实现方式中，该初始路径的初始状态可以通过该第一消息指示该初始路径的初始状态。
应理解，在本申请的实施例中，第一承载配置可以为激活态或去激活态；第二承载配置也可以为激活态或去激活态。
220，该第一设备该第一消息确定该承载配置和该承载配置的初始状态。
第一设备根据第二设备发送的第一消息，其中，第一消息用于指示该第一设备的承载的承载配置和该承载配置的初始状态，确定第一设备的该承载配置和该承载配置的初始状态。
在本申请实施例的技术方案中，第一设备通过接收第二设备发送的第一消息，根据第一消息确定第一设备的承载的承载配置的同时确定其承载配置的初始状态，提高了通信的效率，节约了信令开销。
下面，对该第一消息的具体内容进行详细描述。第一消息的内容包括但不限于以下方式：
方式一
在本申请的实施例中，第一消息中包括第一指示信息时，指示第一设备的承载为第一承载配置；
第一消息中不包括第一指示信息时，指示第一设备的承载为第二承载配置。
例如，第一承载可以为配置了重复传输的承载，第二承载可以为split承载。第一消息中包括以下的第一指示信息时，用于指示配置了重复传输的承载。
pdcp-Duplication(若第一消息中出现该字段，则第一设备的承载为配置了重复传输的承载；若第一消息中未出现该字段，则第一设备的承载为split承载)，此处为举例说明，并未对此进行特别限定。
在本申请的实施例中，当第一消息中出现第一指示信息时，说明第一设备为第一承载配置，即第一设备配置了重复传输的承载。此时，第一指示信息的值用于指示第一设备的承载为第一承载配置时的初始状态。
例如，通过上述pdcp-Duplication的值用于指示配置了重复传输的承载的激活态与去激活态。
在本申请的实施例中，当第一设备的承载包括两个路径时，该第一指示信息的值用于指示该第一承载配置的初始状态，该初始状态包括激活态或去激活态。
当第一设备的承载包括两个路径时，可以用1比特指示第一承载的初始状态，即用1比特指示第一设备的配置了重复传输的承载的激活态与去激活态。
当第一设备的承载包括两个路径时，可以用取值范围为0到1指示第一承载的激活态或者去激活态。
例如，可以用“1”来指示两个路径均为激活态，可以用“0”来指示两个路径均为去激活态。配置了重复传输的承载的激活态指两个路径上传输相同的PDU，配置了重复传输的承载的去激活态指只有初始路径处于工作状态。
应理解，在本申请的实施例中，初始路径为第一设备的承载包括多个路径时，若在所有路径均处于配置了重复传输的承载的去激活态时，一直处于工作状态的路径。在第一消息中，包括指示信息用于指示多个路径时的初始路径的标识。
当第一设备的承载包括两个路径时，可以用2比特指示第一承载的初始状态，即用2比特指示第一设备的配置了重复传输的承载的激活态与去激活态。
例如，可以用“11”指示两条路径均为激活态；可以用“10”指示第一条路径为激活态，第二条路径为去激活态；可以用“01”指示第一条路径为去激活态，第二条路径为激活态；可以用“00”指示两条路径均为去激活态。需要说明的是，针对不同的路径，其具有不同的逻辑信道标识(Logical Channel Identify，LCID)，根据LCID区分不同的路径。
在本申请的实施例中，当第一设备的承载包括N个路径时，第一承载配置的初始状态可以包括该N个路径中除初始路径外的N-1个路径的初始状态，其中，该N-1个路径的初始状态包括均为激活态或均为去激活态，该第一指示信息的值可以包括1个比特，该1比特用于指示该N-1个路径的初始状态，N为大于1的正整数。
例如，当第一设备的承载包括4个路径时，可以用1比特指示第一设备承载包括的4个路径中除了初始路径外的3个路径的第一承载配置的初始状态，即用1比特指示第一设备的配置了重复传输的承载的激活态与去激活态。
例如，可以用“1”来指示3个路径均为激活态，可以用“0”来指示3个路径均为去激活态。配置了重复传输的承载的激活态指3个路径上传输相同的PDU，配置了重复传输的承载的去激活态指只有初始路径处于工作状态。
在本申请的一个实施例中，当第一设备的承载包括N个路径时，该第一承载配置的初始状态可以包括该N个路径中除初始路径外的N-1个路径的初始状态，其中，N-1个路径的初始状态包括激活态或去激活态，该第一指示信息的值可以包括N-1个比特或者该第一指示信息的值的取值范围为0到2 (N-1)-1，该N-1个比特用于指示该N-1个路径的初始状态，N为大于1的正整数。
应理解，初始路径一直处于工作状态，因此当第一设备的承载包括N个路径时只需要确定除过初始路径外的N-1个路径的初始状态，N-1个路径的初始状态包括激活态和去激活态，若N-1个路径中的任意一个初始路径为激活态，则意味该路径与初始路径传输相同的PDU。
例如，当第一设备的承载包括4个路径时，可以用3比特来指示第一承载除初始路径外的3个路径的初始状态，即用3比特指示第一设备除初始路径外的3个路径的初始状态的配置了重复传输的承载的激活态与去激活态，不指示初始路径的初始状态。
该第一指示信息的值为3个比特，该3个比特分别依次指示除了初始路径外第一路径、第二路径、第三路径的初始状态。
例如，可以用“111”指示3个路径均为激活态；可以用“110”指示第一路径和第二 路径为激活态，第三路径为去激活态；可以用“101”指示第一路径和第三路径为激活态，第二路径为去激活态；可以用“100”指示第一路径为激活态，第二路径和第三路径为去激活态；可以用“011”指示第一路径的去激活态，第二路径和第三路径的激活态；可以用“010”指示第一路径和第三路径的去激活态，第二路径的激活态；可以用“001”指示第一路径和第二路径的去激活态，第三路径的激活态；可以用“000”指示3个路径均为去激活态。应理解，此处也可以“0”表示激活，“1”表示去激活，本申请不作限定。
指示的第一路径、第二路径、第三路径即3个比特与配置的路径的对应顺序可以为：
按照该3个路径的逻辑信道标识LCID从大到小的顺序排列；或
按照该3个路径的LCID从小到大的顺序排列；或
按照该3个路径的LCID配置的顺序排列；或

需要说明的是，此处第一指示信息的值用于指示第一设备的承载配置的初始状态，例如，指示第一设备的承载配置为第一承载配置时，第一承载配置可以为配置duplication，第一承载配置的初始状态包括激活态和去激活态。上述为举例说明，并未对此进行特别限 定。
上述为关于第一消息中包括第一指示信息，第一指示信息的值用于指示第一设备承载配置的初始状态的详细描述。应理解，上述为举例说明，不对本申请实施例作任何限定。
方式二
在本申请的实施例中，第一消息可以包括第二指示信息，该第二指示信息用于指示该第一设备的该承载配置，即第二指示信息用于指示该第一设备的承载的该承载配置，其中该承载配置包括第一承载配置和/或第二承载配置。
第一消息中还包括第三指示信息，该第三指示信息用于指示该第一设备的承载的该初始状态，其中，该初始状态至少包括激活态和去激活态。
例如，第一消息中包括以下的第二指示信息，指示该第一设备的该承载配置。第一承载可以为配置了重复传输的承载，第二承载可以为split承载。
Split bearer(第一消息包括第二指示信息，若第二指示信息中出现该字段，当该字段被设置时则指示第一设备的承载为配置了重复传输的承载；若第二指示信息中出现该字段，当该字段未被设置时则指示第一设备的承载为split承载)，此处为举例说明，并未对此进行特别限定。
第一消息中还包括第三指示信息，第三指示信息用于指示该第一设备的承载的该初始状态
例如，第一消息中可以包括以下的第三指示信息。
pdcp-Duplication当出现该字段时，根据该字段的值用于指示该第一设备的承载的初始状态，其中，该初始状态至少包括激活态和去激活态。
例如，该字段的值为“1”时，指示第一设备的承载的初始状态为激活态；该字段的值为“0”时，指示第一设备的承载的初始状态为去激活态。应理解，此处为举例说明，并未对此进行特别限定。
当第一设备的承载包括两个路径时，第三指示信息的值可以用2比特指示第一承载的初始状态，即用2比特指示第一设备的配置了重复传输的承载的激活态与去激活态。
例如，可以用“11”指示两条路径均为激活态；可以用“10”指示第一条路径为激活态，第二条路径为去激活态；可以用“01”指示第一条路径为去激活态，第二条路径为激活态；可以用“00”指示两条路径均为去激活态。需要说明的是，针对不同的路径，其具有不同的逻辑信道标识(Logical Channel Identify，LCID)，根据LCID区分不同的路径。
在本申请的实施例中，当第一设备的承载包括N个路径时，第一承载配置的初始状态可以包括该N个路径中除初始路径外的N-1个路径的初始状态，其中，该N-1个路径的初始状态包括均为激活态或均为去激活态，该第三指示信息的值可以包括1个比特或取值范围为0到1，该1比特用于指示该N-1个路径的初始状态，N为大于1的正整数。
例如，当第一设备的承载包括3个路径时，可以用1比特指示第一承载的初始状态，即用1比特指示第一设备的配置了重复传输的承载的激活态与去激活态。
例如，可以用“1”来指示3个路径均为激活态，可以用“0”来指示3个路径均为去激活态。配置了重复传输的承载的激活态指3个路径上传输相同的PDU，配置了重复传输的承载的去激活态指只有初始路径处于工作状态。
在本申请的一个实施例中，当第一设备的承载包括N个路径时，该第一承载配置的初 始状态可以包括该N个路径中除初始路径外的N-1个路径的初始状态，其中，N-1个路径的初始状态包括激活态或去激活态，该第三指示信息的值可以包括N-1个比特或者该第三指示信息的值的取值范围为0到2 (N-1)-1，该N-1个比特用于指示该N-1个路径的初始状态，N为大于1的正整数。
应理解，初始路径一直处于工作状态，因此当第一设备的承载包括N个路径时只需要确定除过初始路径外的N-1个路径的初始状态，N-1个路径的初始状态包括激活态和去激活态，若N-1个路径中的任意一个初始路径为激活态，则意味该路径与初始路径传输相同的PDU。
例如，当第一设备的承载包括4个路径时，可以用3比特来指示第一承载除初始路径外的3个路径的初始状态，即用3比特指示第一设备除初始路径外的3个路径的初始状态的配置了重复传输的承载的激活态与去激活态，不指示初始路径的初始状态。
该第三指示信息的值为3个比特，该3个比特分别依次指示除了初始路径外第一路径、第二路径、第三路径的初始状态。
例如，可以用“111”指示3个路径均为激活态；可以用“110”指示第一路径和第二路径为激活态，第三路径为去激活态；可以用“101”指示第一路径和第三路径为激活态，第二路径为去激活态；可以用“100”指示第一路径为激活态，第二路径和第三路径为去激活态；可以用“011”指示第一路径的去激活态，第二路径和第三路径的激活态；可以用“010”指示第一路径和第三路径的去激活态，第二路径的激活态；可以用“001”指示第一路径和第二路径的去激活态，第三路径的激活态；可以用“000”指示3个路径均为去激活态。应理解，此处也可以“0”表示激活，“1”表示去激活，本申请不作限定。

按照该3个路径的逻辑信道标识LCID从大到小的顺序排列；或
