Description

一种重复传输的配置及重复传输方法及装置
本申请要求在2017年6月15日提交中国专利局、申请号为201710453584.1、申请名称为“一种重复传输的配置及重复传输方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，特别涉及一种重复传输的配置及重复传输方法及装置。
背景技术
5G NR(next generation Radio，下一代无线)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(3rd Generation Partnership Project，第三代移动通信标准化组织)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，分组数据聚合协议)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。
图1为CA(Carrier aggregation，载波聚合)下重复传输模型示意图，图2为DC(Dual connectivity，双连接)下重复传输模型示意图，CA和DC下的重复传输的模型如图1、2所示，即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)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。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(Media Access Control，媒体接入控制)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。对于DC模型，duplication RB(重复RB；RB：Radio Bearer，无线承载)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。
重复传输是为了保障数据可靠传输，但所有数据都采用重复传输，则会带来无线资源的极大浪费，因此，需要引入有效的重复传输控制机制，即保障特定业务的可靠性的同时通过资源利用率。同时，还需要考虑节约控制信令开销。
重复传输机制主要由于URLLC引入，同时也适用于其他业务。需要对重复传输机制进行合理应用，但现有技术的不足在于，目前尚无很好的解决方案。

具体实施方式
为了支持低时延高可靠业务传输需求，5G NR引入了重复传输机制。重复传输机制可以应用于任何一种业务，但不同业务有不同的时延可靠性需求，本申请实施例中将给出一种有效应用重复传输的方案，保证重复传输只针对必要的业务，和只在必要的时候进行，在增强特定业务传输可靠性，降低传输时延的同时，保证空口资源的合理、有效利用，同时降低控制重复传输的信令开销。下面结合附图对本申请的具体实施方式进行说明。
图3为重复传输的配置方法实施流程示意图，如图所示，可以包括：
步骤301、确定终端的每个无线承载；
步骤302、针对每个无线承载进行重复传输配置。
具体的，网络侧针对终端的每个无线承载进行重复传输(duplication)配置，配置内容包括重复传输初始状态、是否允许激活或去激活等。
其中，重复传输配置采用RRC信令，激活或去激活采用MAC层信令(即MAC CE)。也即，实施中，可以采用RRC信令针对每个无线承载进行重复传输配置。可以采用MAC层信令对无线承载的重复传输配置进行激活或去激活。
这样，通过重复传输配置，终端重复传输的业务可能有三类：
初始状态为激活，可以通过底层信令(MAC CE，MAC控制单元)进行激活或去激活；
初始状态为去激活，可以通过底层信令(MAC CE，MAC控制单元)进行激活或去激活；
初始状态为激活，且一旦配置，保持激活重复传输，不允许底层激活或去激活重复传输。
下面再进行进一步说明如下：
实施中，针对每个无线承载进行以下内容之一或者其组合的重复传输配置：
RB ID，以及该承载对应的PDCP实体配置；
该无线承载用于重复传输的对应的两个LCID，以及这两个逻辑信道分别对应的RLC实体的配置；
对于上行传输，配置两条逻辑信道的初始状态为是否在配置后立即处于激活状态；
对于上行传输，配置是否允许激活或去激活重复传输。
具体实施中，用于重复传输配置的RRC信令中，重复传输配置是针对每个无线承载进行，信令内容可以包括：
1、RB ID(标识)，该承载对应的PDCP实体配置；
2、该承载对应的两个LCID(Logical Channel ID，逻辑信道标识)，这两个逻辑信道分别对应的RLC实体的配置；
3、对于下行传输，基站只需要配置无线承载和对应的两条逻辑信道，是否激活或去激活重复传输是基站侧实现行为，不需另外的信令和操作；
4、对于上行传输，RRC信令中还可以包括：两条逻辑信道的初始状态，即对应逻辑信道是否在配置后立即处于激活状态，可以分为：
有一条逻辑信道初始配置为非激活状态，或，
两条逻辑信道都初始配置为激活状态。
5、对于上行传输，RRC信令中还可以包括：是否允许激活或去激活重复配置，该选项可以针对两条逻辑信道分别配置，也可以针对该无线承载配置，该选项为可选项。
如果无线承载的某条逻辑信道配置后处于非激活状态，则“是否允许激活或去激活重复配置”选项可以不出现，该无线承载允许使用MAC层信令进行激活或去激活重复配置，即允许用MAC层信令激活该配置后初始状态为非激活的逻辑信道，也可以用MAC层信令随后进行去激活重复传输；
如果无线承载的两条逻辑信道在配置后的初始状态都为激活状态，则“是否允许激活或去激活重复配置”选项用于指示某条逻辑信道是否允许去激活，如果该选项不出现，可以理解为该无线承载的两条逻辑信道都不允许去激活，即重复传输机制配置后持续生效。
实施中，可以采用MAC层信令对无线承载的重复传输进行激活或去激活。
具体实施中，进行激活或去激活的MAC层信令为一个不带MAC层负荷的独立的MAC子头。
具体实施中，使用MAC子头中的域表示该MAC CE用于重复传输激活或去激活。
具体实施中，用MAC子头中的LCID域表示该MAC CE用于激活或去激活重复传输，另一个域表示具体是激活还是去激活，其中，用1个LCID值表示该MAC CE为激活或去激活重复传输的MAC CE，用CE Type域的不同取值指示该MAC CE为激活重复传输MAC CE或去激活重复传输MAC CE；
或，用MAC子头中的LCID域表示该MAC CE用于激活或去激活重复传输，其中，用2个LCID值分别表示激活重复传输MAC CE和去激活重复传输MAC CE。
具体的，激活或去激活命令MAC命令的格式为一个独立的MAC子头，不带MAC层负荷(payload)。使用MAC子头中的域表示该MAC CE(Control Element，控制单元)用于重复传输激活或去激活。该重复传输激活或去激活 命令只针对上行传输，是基站发送给终端的。实施中采用的MAC命令(即MAC CE)只包括一个MAC子头，极大地节约了MAC层信令开销。
具体有以下两种方式：
