Description

一种被用于无线通信的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，尤其是支持蜂窝网的无线通信系统中的无线信号的传输方法和装置。
背景技术
在5G系统中，为了支持更高要求的URLLC(Ultra Reliable and Low Latency Communication，超高可靠性与超低时延通信)业务，比如更高可靠性(比如：目标BLER为10^-6)、更低延迟(比如：0.5-1ms)等，在3GPP(3rd Generation Partner Project，第三代合作伙伴项目)RAN(Radio Access Network，无线接入网)#80次全会上通过了对NR(New Radio，新空口)URLLC进行增强的研究项目。为了支持URLLC业务更高可靠性和更低延迟的要求，3GPP已经同意在URLLC中引入不同优先级(Priority)的数据传输和UCI(Uplink Control Information，上行控制信息)反馈。
发明内容
在NR URLLC的讨论中，3GPP引入了优先级信息(包括高优先级(High priority)和低优先级(Low priority))以支持不同类型的控制信息和数据(Data)的传输。在3GPP的Release 15版本中，UCI(尤其是HARQ(Hybrid Automatic Repeat reQuest，混合自动重传请求)反馈信息)可以(Multiplex)和数据一起被复用(Multiplexing)在同一个信道(如，PUSCH(Physical Uplink Shared CHannel，物理上行共享信道))上以提升系统效率。然而，在引入优先级信息后如何合理地将不同优先级的控制信息和数据进行复用是一个需要解决的问题。
针对上述问题，本申请公开了一种解决方案。需要说明的是，在本申请的描述中，只是采用NR URLLC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 URLLC之外的其它场景，也可以取得类似NR URLLC场景中的技术效果。在不冲突的情况下，本申请的任一节点中的实施例和实施例中的特征可以应用到任一其他节点中。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。
