Description

一种用于无线通信的通信节点中的方法和装置 技术领域
本申请涉及无线通信系统中的传输方法和装置，尤其涉及随机接入的传输方案和装置。
背景技术
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次全会上决定对新空口技术(NR，New Radio)(或5G)进行研究,在3GPP RAN#75次全会上通过了新空口技术(NR，New Radio)的WI(Work Item，工作项目)，开始对NR进行标准化工作。
为了能够适应多样的应用场景和满足不同的需求，在3GPP RAN#76次全会上还通过了NR下的非正交多址接入(NoMA，Non-orthogonal Multiple Access)的研究项目，该研究项目在R16版本开始，在SI结束后启动WI对相关技术进行标准化。作为承接NoMA研究项目，在3GPP RAN#82次全会上通过了NR下的两步随机接入(2-step RACH)的WI。
发明内容
对于R16及以后的版本的用户设备(UE，User Equipment)既可以采用两步随机接入又可以采用传统的4步随机接入过程。并且按照两步随机接入的WI的要求，用户设备可以在2步随机接入和4步随机接入之间转换或者从2步随机接入回退到4步随机接入。由于2步随机接入和4步随机接入所面向的应用场景有所不同，因此可能对2步随机接入和4不随机接入的性能要求也有所区别，比如不同的时延要求，不同的碰撞概率的要求，不同的容量的要求等。
本申请提供了一种针对2步随机接入和4步随机接入的不同要求的解决方案。需要说明的是，在不冲突的情况下，本申请的基站设备中的实施例和实施例中的特征可以应用到用户设备中，反之亦然。进一步的，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。
