Description

一种传输数据的方法、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，PDCP协议层发端可以支持数据复制功能，即将一个分组数据汇聚层协议(Packet Data Convergence Protocol,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，接收端在接收到这些复制数据时，不作处理，直接推送到高层，这样就使得高层出现了多个重复数据，从而导致终端设备不能有效处理复制数据。

 本发明的最佳实施方式
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，简称为“GSM”）系统、码分多址（Code Division Multiple Access，简称为“CDMA”）系统、宽带码分多址（Wideband Code Division Multiple Access，简称为“WCDMA”）系统、通用分组无线业务（General Packet Radio Service，简称为“GPRS”）、长期演进（Long Term Evolution，简称为“LTE”）系统、LTE频分双工（Frequency Division Duplex，简称为“FDD”）系统、LTE时分双工（Time Division Duplex，简称为“TDD”）、通用移动通信系统（Universal Mobile Telecommunication System，简称为“UMTS”）、全球互联微波接入（Worldwide Interoperability for Microwave Access，简称为“WiMAX”）通信系统或未来的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，简称为“SCMA”）系统、低密度签名（Low Density Signature，简称为“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，简称为“OFDM”）、滤波器组多载波（Filter Bank Multi-Carrier，简称为“FBMC”）、通用频分复用（Generalized Frequency Division Multiplexing，简称为“GFDM”）、滤波正交频分复用（Filtered-OFDM，简称为“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。

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分别映射到不同的无线链路控制(Radio Link Control，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)，对于媒体接入控制(Media Access Control，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。
在载波聚合场景下，利用PDCP的复制数据功能，从而使复制的数据（也就是PDCP PDU）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。
在MAC层获知哪些逻辑信道传输同一个PDCP PDU的复制数据之后，如何向终端设备指示，从而使得终端设备可以通过该指示确定哪些是属于同一个PDCP PDU的复制数据，进一步地终端设备可以对确定的这些复制数据进行可能的合并接受处理或者对反馈信息传输进行优化。
图3示出了本申请实施例的传输数据的方法100的示意性框图。如图3所示，该方法100的执行主体可以是终端设备，例如可以是用户设备，该方法100包括：
S110，接收网络设备发送的多个混合自动重传请求HARQ进程中的数据；
S120，根据该多个HARQ进程，确定该多个HARQ进程的每个进程中的数据为同一个分组数据汇聚层协议PDCP协议数据单元PDU的复制数据；
S130，对该复制数据进行合并处理或统一反馈。
具体地，网络设备在确定对PDCP PDU1的复制数据进行传输时，首先可以确定哪些HARQ进程用来传输这些复制数据，并通过这些进程进行传输，网络设备可以给终端设备一些指示来判断网络设备同时发过来的多个HARQ进程中的哪些HARQ进程中传输的数据是复制数据，例如可以预先配置哪些HARQ进程用于传输复制数据，哪些HARQ进程用于传输非复制数据，那么终端设备在接收到多个HARQ进程中的数据之后，可以根据这些HARQ进程的标识信息以及网络设备预配置的信息，即可确定哪些HARQ进程中传输的数据是复制数据，哪些HARQ进程中的数据是非复制数据。进一步地，终端设备还可以判断哪些HARQ进程中的复制数据是属于同一个PDCP PDU的复制数据。进一步地，终端设备在知道了哪些HARQ进程中的数据是承载了同一个PDCP PDU的复制数据之后，就可以对同一个PDCP PDU的复制数据进行处理，例如可以只对一个复制数据进行反馈，其余相同的数据不进行反馈，从而可以节省反馈开销。
因此，本申请实施例提供了一种传输数据的方法，通过配置一些HARQ进程传输复制数据，并告知终端哪些HARQ进程里的数据是复制数据，从而终端设备可以对确定的这些复制数据进行可能的合并接收或优化反馈。
应理解，终端设备可能同时会接收到属于多个PDCP PDU的复制数据。其中，每一份复制数据利用一个HARQ进程传输。网络设备可以将很多个HARQ进程按HARQ实体划分成多个组，例如，MAC层有两个HARQ实体，HARQ实体a和HARQ实体b，其中，HARQ实体a管理3个HARQ进程，分别为HARQ 1a、HARQ 2a、HARQ 3a，HARQ实体b管理5个HARQ进程，分别为HARQ 1b、HARQ 2b、HARQ 3b、HARQ 4b以及HARQ 5b。网络设备可以配置HARQ实体a管理的2个HARQ进程用于传输一个PDCP PDU的复制数据，配置HARQ实体b管理的4个HARQ进程用于传输另一个PDCP PDU的复制数据。若网络设备确定有两个PDCP PDU的复制数据需要传输，并且PDCP PDU1的复制数据为两份，PDCP PDU的复制数据为三份，那么网络设备可以采用HARQ实体a管理的其中两个HARQ进程，HARQ 1a、HARQ 2a来传输PDCP PDU1的复制数据，网络设备可以采用HARQ实体b管理的其中4个HARQ进程，HARQ 1b、HARQ 2b、HARQ 3b、HARQ 4b来传输PDCP PDU2的复制数据。终端设备在接收到HARQ 1a、HARQ 2a、HARQ 1b、HARQ 2b、HARQ 3b和HARQ 4b这六个HARQ进程中的数据之后，可以通过预配置的每个HARQ实体管理的HARQ进程的类型，即用于传输复制数据的类型和用于传输非复制数据的类型，就可以判断出HARQ 1a和HARQ 2a中的数据为同一个PDCP PDU的复制数据，HARQ 1b、HARQ 2b、HARQ 3b和HARQ 4b中的数据为另一个PDCP PDU的复制数据。
网络设备也可以不按HARQ实体对HARQ进程进行分组，也就是说网络设备可以直接配置多个HARQ进程属于组1，另外多个HARQ进程属于组2。以上述为例，网络设备可以将HARQ实体a管理的HARQ 1a和HARQ实体b管理的HARQ 1b配置为组1，HARQ实体a管理的其他HARQ进程和HARQ实体b管理的其他进程配置为组2，终端设备可以根据接收到的HARQ进程的标识信息，进而可以判断哪些HARQ进程是一组，哪些HARQ进程属于另外一组，再进一步地按照网络设备的指示或者预配置，确定出同一组中的哪些HARQ进程中传输的数据为复制数据。
可选地，在本申请实施例中，该多个HARQ进程与多个物理载波一一对应，该接收网络设备发送的多个混合自动重传请求HARQ进程中的数据，包括：从该多个物理载波上接收该网络设备发送的该多个HARQ进程中的数据。
网络设备可以配置多个HARQ进程与物理载波的对应关系，具体地，可以配置HARQ实体与物理载波之间的对应关系，例如，网络设备可以配置一个HARQ实体对应一个物理载波。也就是说，若上述HARQ实体a对应物理载波1，上述HARQ实体b对应物理载波2，那么HARQ实体a管理的HARQ 1a和HARQ 2a中的数据在物理载波1上传输，HARQ实体b管理的HARQ 1b、HARQ 2b、HARQ 3b、HARQ 4b以及HARQ 5b中的数据在物理载波2上传输。同样地，若HARQ 1a和HARQ 1b用于传输PDCP PDU1的复制数据，那么终端设备可以分别在物理载波1上和物理载波2上接收HARQ 1a和HARQ 1b中的数据，并且可以判断出来HARQ 1a和HARQ 1b中的数据为复制数据，网络设备通过不同载波向终端设备发送同一个PDCP PDU的复制数据，从而达到频率分集增益以提高数据传输可靠性。
应理解，不同的HARQ实体可以管理不同数量或不同数量的HARQ进程，并且不同HARQ实体管理的HARQ进程在所在组内的标识可以相同也可以不同，例如，HARQ实体a管理的两个HARQ进程在组内可以标识为HARQ 1和HARQ 2，HARQ实体b管理的五个HARQ进程在组内可以标识为HARQ 1、HARQ 2、HARQ 3、HARQ 4以及HARQ 5，本申请实施例并不限于此。
还应理解，网络设备可以配置同一个HARQ实体内的多个HARQ进程可以分成两类，一种是用于传输复制数据的HARQ进程，一种是用于传输非复制数据的HARQ进程。例如，网络设备可以配置HARQ实体a中的HARQ 1a为用于传输复制数据的HARQ进程，HARQ 2a为用来传输非复制数据的HARQ进程。网络设备还可以把对每个HARQ实体中管理的HARQ进程的类型的配置发送给终端设备，从而终端设备在接收到多个HARQ进程传输的数据之后，通过查找上述配置，根据各个HARQ进程的类型，即可判断出来哪些个HARQ进程中的数据是属于同一个PDCP PDU中的复制数据。
可选地，在本申请实施例中，该方法还包括：在该多个物理载波中的第一物理载波上接收该网络设备发送的指示信息，该指示信息用于指示与该指示信息对应的该多个HARQ进程中的每个HARQ进程中的数据为复制数据；该根据该多个HARQ进程，确定该多个HARQ进程的每个进程中的数据为同一个分组数据汇聚层协议PDCP协议数据单元PDU的复制数据，包括：根据该多个HARQ进程和该指示信息，确定该多个HARQ进程中的每个HARQ进程中的数据为同一个PDCP PDU的复制数据。
可选地，在本申请实施例中，该方法还包括：在该多个物理载波上分别接收该网络设备发送的指示信息，该指示信息用于指示与该指示信息对应的HARQ进程中的数据为复制数据；该根据该多个HARQ进程，确定该多个HARQ进程的每个进程中的数据为同一个分组数据汇聚层协议PDCP协议数据单元PDU的复制数据，包括：根据该多个HARQ进程和该指示信息，确定该多个HARQ进程中的每个HARQ进程中的数据为同一个PDCP PDU的复制数据。
具体地，网络设备动态向终端设备指示哪些HARQ进程属于同一个PDCP PDU的复制数据。例如，可以通过下行控制信息(Downlink Control Information,DCI)动态指示多个HARQ进程中的数据是属于同一个PDCP PDU的复制数据。可以配置一个HARQ进程对应一个载波，也就是说，终端设备在多个载波上接收到对应的HARQ进程中的数据之前，在每个载波上分别接收DCI，该DCI中可以增加一个信息指示域，例如复制数据指示(data duplication indication,DDI),取值为on/off，如果为on，标识该DCI对应的HARQ进程中传输的数据为复制数据，如果为off，则标识该DCI对应的HARQ进程中传输的数据为非复制数据。这里也可以通过一个载波向终端设备发送的DCI中包括网络设备在多个载波上发送的所有HARQ进程中的数据是否是复制数据。例如，网络设备向终端设备向发送了5个HARQ进程中的数据，其中两个HARQ进程对应一个HARQ实体，另外三个HARQ进程对应另一个HARQ实体，两个HARQ进程对应的HARQ实体对应物理载波1，三个HARQ进程对应的HARQ实体对应物理载波2，网络设备可以在物理载波1上发送一个DCI，该DCI指示与该物理载波1对应的两个HARQ进程中的数据是否为复制数据，网络设备可以在物理载波2上发送一个DCI，该DCI指示与该物理载波2对应的三个HARQ进程中的数据是否为复制数据。进而终端设备首先可以判断出来哪些HARQ进程传输的是同一个PDCP PDU，并直接根据相应的指示信息传输同一个PDCP PDU中的HARQ进程的数据是否为复制数据。
应理解，在DCI动态指示的情况下，可以不限制HARQ进程是否属于不同的HARQ实体或者同一个HARQ实体。
可选地，在本申请实施例中，该多个HARQ进程对应至少一个HARQ实体，该至少一个HARQ实体中的每个HARQ实体管理至少一个用于传输复制数据的HARQ进程，该根据该多个HARQ进程，确定该多个HARQ进程的每个进程中的数据为同一个分组数据汇聚层协议PDCP协议数据单元PDU的复制数据，包括：根据该多个HARQ进程和通过高层信令预配置的第一配置信息，确定该多个HARQ中每个HARQ进程中的数据为同一个PDCP PDU的复制数据，该第一配置信息用于指示该多个HARQ进程为用于传输复制数据的HARQ进程。
若终端设备没有在DCI中获取该指示信息，终端设备可以根据上述网络设备对每个HARQ进程的类型的配置来确定哪些HARQ进程中的数据是属于同一个PDCP PDU中的复制数据。例如，终端设备接收到上述7个HARQ进程，分别为HARQ实体a管理的HARQ 1a和HARQ 2a以及HARQ实体b管理的HARQ 1b、HARQ 2b、HARQ 3b、HARQ 4b和HARQ 5b，终端设备通过查表发现HARQ 1a、HARQ 1b、HARQ 2b和HARQ 5b为复制数据类型，并且HARQ1a和HARQ 1b为同一组，那么终端设备可以判断出来HARQ1a和HARQ 1b中的数据为同一个PDCP PDU的复制数据。
可选地，在本申请实施例中，该多个物理载波对应同一个HARQ实体，该根据该多个HARQ进程，确定该多个HARQ进程的每个进程中的数据为同一个分组数据汇聚层协议PDCP协议数据单元PDU的复制数据，包括：根据该多个HARQ进程和通过高层信令预配置的第二配置信息，确定该多个HARQ进程中每个HARQ进程中的数据为同一个PDCP PDU的复制数据，该第二配置信息用于指示该多个HARQ进程属于与该多个物理载波对应的HARQ实体。
与现有的一个HARQ实体对应一个物理载波不同，网络设备还可以配置一个HARQ实体对应多个物理载波，网络设备可以将这种HARQ实体中的某个HARQ实体管理的所有HARQ进程都配置为用于传输某一个PDCP PDU的复制数据的HARQ进程。例如，网络设备可以配置HARQ实体a对应物理载波1和物理载波2，并且可以配置该HARQ实体a管理HARQ 1a、HARQ 2a和HARQ 3a，并且网络设备可以配置HARQ实体a中的所有HARQ进程都用来传输同一个PDCP PDU中的复制数据，当终端设备接收到网络设备发送的HARQ 2a和HARQ 3a，通过查表，可以确定该HARQ 2a和HARQ 3a属于对应2个物理载波的HARQ实体，进一步地终端设备可以确定当前该两个HARQ进程中的数据属于复制数据。
应理解，对应多个物理载波的HARQ实体所管理的多个HARQ进程在多个载波上同时传输。例如，对应多个物理载波的HARQ实体管理两个HARQ进程，HARQ进程1和HARQ进程2，MAC调度器可以同时调度HARQ进程1和HARQ进程2在两个物理载波上同时传输。
可选地，在本申请实施例中，该高层信令为无线资源控制RRC信令。
下面将结合图4和图5详细描述本申请的两个实施例。
实施例一，如图4所示，物理载波1对应HARQ实体 a，物理载波2对应HARQ实体 b。其中HARQ实体 a中的HARQ进程分为两个类型，一个为传输复制数据的类别，即DDC：data duplication category;一个为传输非复制数据的类别，即NDDC: non data duplication category。逻辑信道1和逻辑信道2为分别承载复制数据的逻辑信道，该复制数据到达MAC层，MAC分别把复制数据调度到HARQ实体a的1a和HARQ实体b的1b。终端根据类别，即可知道在载波1和2上，对应HARQ进程1a和HARQ进程1b的数据为复制数据。
实施例二，如图5所示，物理载波1和物理载波2均对应共享HARQ 实体。其中共享HARQ实体中的HARQ进程均为传输复制数据的HARQ进程，标识为{1,2,3,4}。逻辑信道1和逻辑信道2为分别承载复制数据的逻辑信道，该复制数据到达MAC层，MAC分别把复制数据调度到共享HARQ实体的HARQ进程1和HARQ进程2上。终端根据共享HARQ实体配置，即可知道在载波1和2上，对应HARQ进程1和HARQ进程2的数据为复制数据。
