Description

用于传输数据的方法、终端设备和网络设备 技术领域
本申请实施例涉及通信领域，并且更具体地，涉及一种用于传输数据的方法、终端设备和网络设备。
背景技术
在载波聚合场景下，分组数据汇聚层协议(Packet Data Convergence Protocol，PDCP)可以支持数据复制功能，即将一个PDCP协议数据单元(Protocol Data Unit，PDU)复制成两份(可能多份)，以此来提高数据传输的可靠性。现有技术中直接使用PDCP复制数据传输功能的默认状态进行数据传输不够灵活。
发明内容
有鉴于此，本申请实施例提供了一种用于传输数据的方法、终端设备和网络设备，有利于提高数据传输的灵活性。
第一方面，提供了一种用于传输数据的方法，该方法包括：终端设备接收网络设备发送的第一指示信息，该第一指示信息用于指示至少一个无线承载RB中每个RB是否使能复制数据传输功能；该终端设备根据该第一指示信息，向该网络设备发送数据。
由网络设备指示终端设备哪些RB是否使能复制数据传输功能，有利于提高数据传输的灵活性。
可选地，本申请实施例的方案可以应用于上行数据传输的场景，也可应用于终端设备到终端设备(Device-to-Device，D2D)通信场景中。
无线承载(Radio Bearer，RB)是网络设备为用户设备分配的一系列协议实体及配置的总称，包括PDCP协议实体、无线链路控制(Radio Link Control，RLC)协议实体以及媒体接入控制(Media Access Control，MAC)协议实体和物理层PHY分配的一系列资源等。RB包括信令无线承载(Signalling Radio Bearer，SRB)和数据无线承载(Data Radio Bearer，DRB)，SRB是系统的信令消息实际传输的通道，DRB是用户数据实际传输的通道。
其中，使能复制数据传输功能，是指与某个RB对应的PDCP实体将一 个PDCP PDU复制成多份，分别在多个RLC实体上进行传输；而不使能复制数据传输功能也就是不使用复制数据传输功能，即与某个RB对应的PDCP实体传输的PDCP PDU不是复制数据，可以在一个RLC实体中传输一次，也可以将一个PDCP PDU分成多部分在多个RLC实体中传输。
可选地，这里的PDCP PDU可以是一些对数据传输有高可靠性要求的业务。也就是说，在这些业务的PDCP PDU需要传输时，需要确定是否需要对某一个RB使能复制数据传输功能。其它对数据传输没有高要求的PDCP PDU可以不需要确定是否使能某个RB的复制数据传输功能，直接不使能该RB的复制数据传输功能。

可选地，如果该RB之前的状态为停止使用复制数据传输功能，也就是 说该RB之前传输过复制数据，但前一次在该RB传输的是非复制数据，那么网络可能配置给该RB的是一个PDCP实体对应多个RLC实体，但前一次传输时终端设备只采用该多个RLC实体中的某一个RLC实体传输非复制数据或者部分RLC实体传输非复制数据，而如果网络设备指示该RB使能复制数据传输功能，那么终端设备就可以直接使用该多个RLC实体直接传输复制数据或者直接使用该多个RLC实体中的部分RLC实体传输复制数据。

可选地，该第二指示信息可以是某个RLC实体或某些RLC实体对应的逻辑信道的标识。或者也可以采用显性指示的方式指示某个RLC实体某些RLC实体可以用来传输非复制数据，哪些可以停止传输数据。
在一种可能的实现方式中，该终端设备通过与该第一RB对应的PDCP实体对应的逻辑信道，向该网络设备发送非复制数据，包括：在该PDCP实体对应多个逻辑信道的情况下，该终端设备接收该网络设备发送的第二指示信息，该第二指示信息用于指示该多个逻辑信道中不用于传输数据的第一逻辑信道；该终端设备通过该两个逻辑信道中的第二逻辑信道，向该网络设备发送该非复制数据。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
应理解，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)、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、新无线(New Radio，NR)或未来的5G系统等。
特别地，本申请实施例的技术方案可以应用于各种基于非正交多址接入技术的通信系统，例如稀疏码多址接入(Sparse Code Multiple Access，SCMA)系统、低密度签名(Low Density Signature，LDS)系统等，当然SCMA系统和LDS系统在通信领域也可以被称为其他名称；进一步地，本申请实施例的技术方案可以应用于采用非正交多址接入技术的多载波传输系统，例如采用非正交多址接入技术正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)、滤波器组多载波(Filter Bank Multi-Carrier，FBMC)、通用频分复用(Generalized Frequency Division Multiplexing，GFDM)、滤波正交频分复用(Filtered-OFDM，F-OFDM)系统等。
本申请实施例中的终端设备可以指用户设备(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。接入终端可以是蜂窝电话、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)、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、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile  Network，PLMN)中的终端设备等，本申请实施例并不限定。
本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional NodeB，eNB或eNodeB)，还可以是云无线接入网络(Cloud Radio Access Network，CRAN)场景下的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等，本申请实施例并不限定。
图1是本申请实施例一个应用场景的示意图。图1中的通信系统可以包括终端设备10和网络设备20。网络设备20用于为终端设备10提供通信服务并接入核心网，终端设备10通过搜索网络设备20发送的同步信号、广播信号等而接入网络，从而进行与网络的通信。图1中所示出的箭头可以表示通过终端设备10与网络设备20之间的蜂窝链路进行的上/下行传输。
在载波聚合场景下，PDCP可以支持数据复制功能，即利用PDCP的复制数据功能，从而使复制的数据对应到两个或者多个逻辑信道，并最终保证复制的多个相同PDCP PDU能够在不同物理层聚合载波上面传输，从而达到频率分集增益以提高数据传输可靠性。
为了便于理解，下面将结合图2简单介绍如何将复制数据调度在不同的物理载波上。如图2所示，PDCP层具有分裂承载复制功能，将PDCP SDU1的数据进程复制封装成PDCP PDU1和PDCP PDU2，PDCP PDU1和PDCP PDU2具有相同的内容，即承载的数据payload和包头header都相同。分别把PDCP PDU1和PDCP PDU2分别映射到不同的RLC实体，RLC实体把PDCP PDU1和PDCP PDU2放到不同的逻辑信道(逻辑信道1和逻辑信道2上)，对于MAC来讲，在获知哪些逻辑信道传输同一个PDCP PDU的复制数据之后，将这些复制数据通过不同的混合自动重传请求HARQ实体在不同的载波上传输，例如，将逻辑信道1中承载的复制数据通过HARQ实体1在物理载波1上传输，将逻辑信道2中承载的复制数据通过HARQ实体2在物理载波2上传输。
尽管PDCP层复制数据传输能够利用分集增益有效提高数据传输的可靠性，但如何灵活使用PDCP复制数据传输功能，是需要解决的问题。
本领域技术人员理解，上行PDCP数据复制功能是可以基于无线承载RB来进行配置的，也就是说不同的RB可以配置支持PDCP复制数据传输，也可以不配置PDCP复制数据传输。
RB是基站为UE分配的一系列协议实体及配置的总称，包括PDCP协议实体、RLC协议实体以及MAC和PHY分配的一系列资源等。RB包括SRB和DRB，SRB是系统的信令消息实际传输的通道，DRB是用户数据实际传输的通道。
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。
图3示出了本申请实施例的用于传输数据的方法100的示意性框图。如图3所示，该方法100包括：
S110，终端设备接收网络设备发送的第一指示信息，该第一指示信息用于指示至少一个无线承载RB中每个RB是否使能复制数据传输功能；
S120，该终端设备根据该第一指示信息，向该网络设备发送数据。
具体地，网络设备可以自行决定某个RB是否需要使能复制数据传输功能。例如，网络设备可以根据当前业务对数据传输是否有可靠性要求来确定。在对数据传输可靠性要求较高的情况下，可以决定采用复制数据传输。网络设备也可以决定用几个RB以及用哪些RB进行复制数据的传输。并且网络设备可以将选择的RB的标识告诉终端设备，或者网络设备可以告诉终端设备每个RB是否用来传输复制数据。终端设备在接收到网络设备发送的指示信息之后，进而可以根据该指示信息向网络设备发送数据。例如，若该指示信息指示某个RB用来传输复制数据，那么终端设备就可以用该RB向网络设备传输复制数据；若该指示信息指示某个RB用来传输非复制数据，那么终端设备就可以用该RB向网络设备传输非复制数据。
因此，本申请实施例的用于传输数据的方法，基于网络设备的指示发送数据，有利于提高数据传输的灵活性。
可选地，在本申请实施例中，该终端设备接收网络设备发送的第一指示信息，包括：该终端设备接收该网络设备通过媒体接入控制MAC控制元素 CE发送的该第一指示信息。
应理解，本申请实施例提出的第一指示信息可以承载于MAC信令中，第一指示信息也可以承载于其他层的信令中，例如PHY信令、RLC层信令等，本申请实施例不限于此。
可选地，在本申请实施例中，该第一指示信息携带该每个RB的标识，该每个RB的标识用于指示相应的RB使能该复制数据传输功能，或该每个RB的标识用于指示相应的RB停止使用该复制数据传输功能。
具体地，网络设备和终端设备可以提前约定好，网络设备向终端设备发送的RB的标识表示该RB可以使用复制数据传输功能或者网络设备向终端设备发送的RB的标识表示该RB可以不使用复制数据传输功能。那么网络设备在确定了哪些RB可以使用复制数据传输功能或者哪些RB可以不使用复制数据传输功能之后，网络设备可以向终端设备发送这些RB的标识，那么终端设备在接收到这些RB的标识之后，就根据约定好的规则知道哪些RB可以使用复制数据传输功能，哪些RB可以不使用复制数据传输功能，进而终端设备可以使用相应的RB发送复制数据或者非复制数据。
可选地，在本申请实施例中，该第一指示信息为比特图，该比特图中的每个比特位与该每个RB一一对应，该每个比特位的取值表示相应的RB是否使能复制数据传输功能。
具体地，网络设备也可以显示指示某个RB是否使能复制数据传输功能。例如，网络设备可以和终端设备之间提前约定好用1个bit来表示某个RB是否使能复制数据传输功能。如“1”表示该RB使能复制数据传输功能，也就是说终端设备可以使用该RB进行复制数据的传输，“0”表示该RB停止使用复制数据传输功能，也就是说终端设备可以使用该RB进行非复制数据的传输。那么网络设备可以向终端设备一个指示信息，该指示信息中有一个bit单独用来指示该RB是否使能复制数据传输功能，网络设备还可以在指示信息中复用一个bit，也就是说该指示信息中原本就有该bit，是用来指示其他信息，但是可以同时指示该RB是否使能复制数据传输功能。同样地，如果网络设备需要显示指示多个RB是否使能复制数据传输功能，网络设备可以使用一个比特图，该比特图的位数表示网络设备向终端设备指示的RB的数量，该比特图中的每一位都用于指示其代表的RB是否使能复制数据传输功能。举例来说，通常无线通信中DRB的数量最多有8个，可以使用一个8 位的比特图，可以提前将该8个DRB映射到该比特图中，也就是比特图中的每一位都代表了该8个DRB中的一个DRB，并且网络设备和终端设备提前都知道这种映射关系，那么当终端设备接收到该比特图之后，终端设备可以根据这种映射关系，查看每一个bit上代表的DRB是否使能复制数据传输功能。
应理解，上述两种指示方式仅仅是示意性说明，本申请实施例并不限于此，任何指示RB是否使能复制数据传输功能的方式都在本申请实施例的保护范围之内。
可选地，在本申请实施例中，该终端设备根据该第一指示信息，向该网络设备发送数据，包括：该终端设备根据该第一指示信息，确定该至少一个RB中的第一RB使能该复制数据传输功能；该终端设备通过与该第一RB对应的分组数据汇聚协议PDCP实体对应的多个逻辑信道，向该网络设备发送复制数据。
如果网络设备向终端设备指示某个RB使能复制数据传输功能，那么终端设备可以使用该RB向网络设备发送复制数据。具体地，终端设备需要通过与该RB对应的PDCP实体对应的多个RLC实体，向网络设备发送复制数据。其中，一个RLC实体可以对应一个逻辑信道。以图2为例，图2中的整个数据传输路径可以称为一个DRB，图中一个DRB可以包括一个PDCP实体、两个RLC实体，并且通过MAC实体映射到两个不同的物理载波上。如果网络设备指示图2所示的DRB使能复制数据传输功能，那么终端设备就可以直接在PDCP实体处将PDCP PDU复制成两份，分别放在两个RLC实体上进行传输，进而可以将该两个PDU放在不同的物理载波上进行传输，从而可以达到频率分集增益以提高数据传输的可靠性。
应理解，上述是以一个PDCP实体对应两个RLC实体进行复制数据传输为例进行描述，本申请实施例可以将多个RLC实体对应一个PDCP实体，当需要传输复制数据时，可以直接PDCP PDU复制成多份，放在与该PDCP对应的多个RLC上进行传输，本申请实施例并不限于此。
可选地，如果该RB之前的状态为停止使用复制数据传输功能，也就是说该RB之前传输过复制数据，但前一次在该RB传输的是非复制数据，那么网络可能配置给该RB的是一个PDCP实体对应多个RLC实体，但前一次传输时终端设备只采用该多个RLC实体中的某一个RLC实体传输非复制数 据或者部分RLC实体传输非复制数据，而如果网络设备指示该RB使能复制数据传输功能，那么终端设备就可以使用该多个RLC实体直接传输复制数据或者直接使用该多个RLC实体中的部分RLC实体传输复制数据。
可选地，如果RB配置的默认状态是停止使用数据复制传输功能。可以理解为，该RB之前传输的一直都是非复制数据，在这种情况下，网络可以给该RB配置的是一个PDCP对应一个RLC实体，那么当网络设备指示该RB使能复制数据传输功能，终端设备除了使用该PDCP对应的一个RLC实体之外，还需要使用另外至少一个RLC实体向网络设备发送复制数据。该使用的另外一个RLC实体可以是PDCP实体自行决定的，也可以是由网络设备指示的。
可选地，在本申请实施例中，在该终端设备通过与该第一RB对应的分组数据汇聚协议PDCP实体对应的两个逻辑信道，向该网络设备发送复制数据之前，该方法还包括：在该PDCP实体只对应一个逻辑信道的情况下，该终端设备接收第二指示信息，该第二指示信息用于指示用于传输该复制数据的另外至少一个逻辑信道。
具体地，该第二指示信息可以是某个RLC实体或某些RLC实体对应的逻辑信道的标识。换句话说，网络设备可以提前约定好只要终端设备收到某些逻辑信道的标识，则可以表示与该逻辑信道的RLC实体是可以与某个RB的PDCP关联起来的。或者网络设备也可以提前约定好只要终端设备收到某些逻辑信道的标识，则可以表示与该逻辑信道之外的逻辑信道对应的RLC实体是可以与某个RLC实体关联起来的。
同样地，也可以显性指示某个逻辑信道对应的RLC实体是可以跟某个RB对应的PDCP关联起来。假设终端设备可以约定“1”表示逻辑信道0，“0”表示逻辑信道1，那么当终端设备接收到与某个RB相关的该指示信息之后，终端设备就可以知道可以将某个逻辑信道对应的RLC实体与该RB对应的PDCP实体关联起来。
可选地，如果RB配置的默认状态是停止使用数据复制传输功能。可以理解为，该RB之前传输的一直都是非复制数据，在这种情况下，网络可以给该RB配置的是一个PDCP对应多个RLC实体。也就是说网络可以给该RB对应的PDCP实体对应多个RLC实体，但是网络在之前根本就没有使用该多个RLC实体传输复制数据，而是传输的非复制数据，例如，终端设备 可以使用该RB对应的PDCP对应的多个RLC实体中的一个RLC实体或者多个RLC实体传输非复制数据。那么当网络设备指示该RB使能复制数据传输功能，终端设备可以直接使用该多个RLC实体中的部分或全部RLC实体传输复制数据。
应理解，若终端设备使用该多个RLC实体中的部分RLC实体传输复制数据，终端设备自行决定使用那些RLC实体传输复制数据，也可以是由网络设备指示使用那些RLC实体传输复制数据。
还应理解，该指示哪些RLC实体传输复制数据跟前述一样，也可以是向终端设备发送与该RLC实体对应的逻辑信道的标识或者显性指示。
可选地，在本申请实施例中，该终端设备根据该第一指示信息，向该网络设备发送数据，包括：该终端设备根据该第一指示信息，确定该至少一个RB中的第一RB停止使用该复制数据传输功能；该终端设备通过与该第一RB对应的PDCP实体对应的逻辑信道，向该网络设备发送非复制数据。
具体地，如果网络设备向终端设备指示某个RB停止使用复制数据传输功能，也就是说前一次终端设备使用该RB传输的是复制数据，那么与该RB对应的PDCP实体本身就对应多个RLC实体，终端设备在接收到网络设备的指示之后，可以使用与该RB对应的PDCP实体对应的多个RLC实体中的一个或多个RLC实体传输非复制数据。
可选地，终端设备可以基于一定规则自行决定使用该多个RLC实体中的哪些RLC实体进行非复制数据的传输。网络设备也可以向终端设备下发指示，指示使用该多个RLC实体中的哪些RLC实体进行非复制数据的传输。网络设备还可以向终端设备下发指示，指示该多个RLC实体中的哪些RLC实体不能进行非复制数据的传输，那么终端设备就可以使用该多个RLC实体中的其他RLC实体进行非复制数据的传输。终端设备还可以将该多个RLC实体中不用于传输非复制数据的RLC实体释放。
可选地，网络设备可以在一个消息中携带上述第一指示信息和第二指示信息，即上述指示RB是否使能复制数据传输功能的信息和上述指示其他RLC实体对应的逻辑信道的信息。例如，可以使用一个表格，该表格的每一列代表一个RB，该表格的每一行代表第一指示信息或第二指示信息。具体如表1所示。
表1
0 1 0 0 0 1 1 0
0 0 0 0 0 0 1 0
如表1，网络设备可以与终端设备提前约定好该表格的含义，即该表格每一代表什么，每一列代表什么，每个值代表什么。例如，该表1中的第一行表示8个RB中每个RB是否使能复制数据传输功能。该表1中的第二行表示8个RB中每个要停止使用复制数据传输功能的RB停止的是哪个逻辑信道。该表1中的同一列表示同一个RB。在该表中，当第一行表示的RB是使能复制数据传输功能，那么可以忽略该列第二行的值。具体地，上述表1表示RBl、RB5以及RB6是使能复制数据传输功能的，而RB0、RB2、RB3、RB4以及RB7是停止使用复制数据传输功能的。并且RB0、RB2、RB3、RB4以及RB7停止的是逻辑信道0(假设第一行“0”代表停止使用复制数据传输功能，第一行“1”代表使能复制数据传输功能，第二行“0”代表逻辑信道0，第二行“1”代表逻辑信道1)。
应理解，上述是以“0”和“1”两个值为例进行描述的，该第二行的每一位的具体取值还可以是一个集合里的值，应该不限于“0”和“1”，例如，可以分别用“0”-“2”分别代表逻辑信道0至逻辑信道2。本申请实施例并不限于此。并且上述取值代表的含义也不受限制。
图4示出了本申请实施例的用于传输数据的方法200的示意性框图。如图4所示，该方法200包括：
S210，网络设备向终端设备发送第一指示信息，该第一指示信息用于指示至少一个无线承载RB中每个RB是否使能复制数据传输功能；
S220，该网络设备通过该至少一个RB接收该终端设备发送的数据。
因此，本申请实施例的用于传输数据的方法，有利于提高数据传输的灵活性。

可选地，在本申请实施例中，该方法还包括：在该PDCP实体只对应一个逻辑信道的情况下，该网络设备向该终端设备发送第二指示信息，该第二指示信息用于指示用于传输复制数据的另外至少一个逻辑信道。
可选地，在本申请实施例中，该第一指示信息用于指示该至少一个RB中的第一RB停止使用该复制数据传输功能，该网络设备通过该至少一个RB接收该终端设备发送的数据，包括：该网络设备通过与该第一RB对应的PDCP实体对应的逻辑信道，接收该终端设备发送的非复制数据。
可选地，在本申请实施例中，该方法还包括：在该PDCP实体对应多个逻辑信道的情况下，该网络设备向该终端设备发送第二指示信息，该第二指示信息用于指示该多个逻辑信道中用于传输数据的第一逻辑信道或该两多个逻辑信道中不用于传输数据的第二逻辑信道。
