Description

一种副链路中继无线通信的方法和装置 技术领域
本申请涉及无线通信系统中的方法和装置，尤其涉及副链路无线通信中支持中继传输的方法和装置。
背景技术
中继(Relay)作为一种多跳传输技术，可以提升小区边缘吞吐量，提高小区覆盖。以LTE(Long Term Evolution,长期演进)系统中的副链路(Sidelink)SL传输为例，用户设备(User Equipment，UE)到中继节点(relay node，RN)的传输采用副链路空口技术，RN到基站(eNodeB，eNB)的传输采用LTE空口技术传输。RN用于UE和eNB之间的数据转发，称为IP(Internet Protocol，互联网协议)层转发或者层3中继(Layer 3Relay/L3Relay)。
未来无线通信系统的应用场景越来越多元化，不同的应用场景对系统提出了不同的性能要求。为了满足多种应用场景的不同的性能需求，在3GPP(3rd Generation Partner Project，第三代合作伙伴项目)RAN(Radio Access Network，无线接入网)#72次全会上决定对NR(New Radio，新空口)技术(或Fifth Generation，5G)进行研究,在3GPP RAN#75次全会上通过了NR的WI(Work Item，工作项目)，开始对NR进行标准化工作。针对迅猛发展的V2X(Vehicle-to-Everything，车联网)业务，3GPP也开始启动了在NR框架下的标准制定和研究工作，在3GPP RAN#86次全会上决定对NR SL(Sidelink，副链路)Relay启动SI(Study Item，研究项目)标准化工作。
发明内容
发明人通过研究发现，NR V2X支持丰富的应用场景，每种业务具有不同的QoS(Quality of Service，业务质量)需求，不同的QoS需求通过不同的QoS参数组(Parameters)定义，QoS参数组中的参数包括但不限于PQI(PC5 5G QoS Identifier,PC5 5G质量标识),PC5Flow bit rate(PC5流比特率)，PC5Link Aggregated Bit Rate(PC5链路综合比特率)，Range(传输距离)中的一个或多个。其中PQI参数在Tx UE侧被映射成QoS特性，其中一个QoS特性为数据包延时预算(Packet Delay Budget)，即一个业务流的数据包的传输延时不能大于数据包延时预算。在中继传输中，由于引入中继节点，使得原来Tx UE到Rx UE的一跳传输分成Tx UE到中继节点，中继节点到Rx UE两跳完成，如何将目标数据包延时预算在这两跳传输中合理分配以满足业务流的传输延时需求需要研究。
针对上述问题，本申请公开了一种解决方案。在本申请的描述中，只是采用NR V2X场景作为一个典型应用场景或者例子；本申请也同样适用于面临相似问题的NR V2X之外的其它场景(比如中继网络，D2D(Device-to-Device，设备到设备)网络，蜂窝网络，支持半双工用户设备的场景)，也可以取得类似NR V2X场景中的技术效果。此外，不同场景(包括但不限于NR V2X场景，下行通信场景等)采用统一解决方案还有助于降低硬件复杂度和成本。在不冲突的情况下，本申请的第一节点中的实施例和实施例中的特征可以应用到任一其它节点中，反之亦然。在不冲突的情况下，本申请的实施例和实施例中的特征可以任意相互组合。特别的，对本申请中的术语(Terminology)、名词、函数、变量的解释(如果未加特别说明)可以参考3GPP的规范协议TS36系列、TS38系列、TS37系列中的定义。
