Description

一种用于无线通信的方法和装置 技术领域
本发明涉及无线通信系统中的方法和装置,尤其涉及无线通信系统中的多载波的传输方案和装置。
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。
在新空口技术中,多载波(包括载波聚合和双连接等)技术是重要的组成部分。为了能够适应多样的应用场景和满足不同的需求,3GPP从Rel-15版本一直在对多载波技术进行演进。
发明内容
在多载波通信过程,比如载波聚合(CA,Carrier Aggregation)中,系统支持跨载波调度(Cross Carrier Scheduling)。在现有标准支持的网络中,比如R17及以前版本的5G NR(New Radio,新空口),对于多个被调度载波,只支持在分别对应的载波或对应的PDCCH(Physical Downlink Control Channel,物理下行控制信道)上进行调度,而不支持通过同一个载波上的同一个PDCCH进行调度。在Rel-18的相关讨论中,关于多载波增强的课题开始被讨论,而在此课题下,一个PDCCH可以同时调度位于多个载波上的数据信道,以提高整体性能。
针对在NR的多载波系统中一个PDCCH同时调度多个载波的问题,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,只是以多载波中的PDCCH调度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其它场景(比如其它对控制信道容量有更高要求的场景,包括但不限于容量增强系统、采用更高频率的系统、覆盖增强系统、非授权频域通信、IoT(Internet of Things,物联网)、URLLC(Ultra Reliable Low Latency Communication,超鲁棒低时延通信)网络、车联网等),也可以取得类似的技术效果。此外,不同场景(包括但不限于多载波的场景)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,本申请的第一节点设备中的实施例和实施例中的特征可以应用到第二节点设备中,反之亦然。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。在需要的情况下,可以参考3GPP标准TS38.211,TS38.212,TS38.213,TS38.214,TS38.215,TS38.321,TS38.331,TS38.305,TS37.355以辅助对本申请的理解。
