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，尤其涉及无线通信中的控制信道的传输方案和装置。
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，多天线(比如多输入多输出(MIMO，Multiple Input Multiple Output),多发送接收节点(TRP，Transmission Reception Point)和多面板(Pannel))技术是重要的组成部分。为了能够适应更加多样的应用场景和满足更高的需求，在3GPP RAN#86次全会上通过了NR下的MIMO的进一步增强的WI用来支持更加鲁棒和频谱效率更高以及更多应用场景的多天线通信。
发明内容
在多天线系统中，比如多发送接收节点(TRP，Transmission Reception Point)通信中，同一个信道或者信号可以通过多个发送接收节点传输来增强传输的鲁棒性。在版本16(Rel-16)中支持了数据信道的多发送接收节点传输，3GPP计划在版本17(Rel-17)中引入控制信道的多发送接收节点传输。
针对在多天线系统中的控制信道的传输问题，本申请公开了一种解决方案。需要说明的是，在本申请的的描述中，只是多天线系统，特别是多发送接收节点传输系统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(比如对控制信道的鲁棒性或者覆盖有更高要求的场景，或者在多发送接收节点传输之外需要PDCCH相关联的场景，包括但不限于覆盖增强系统、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(包括但不限于多天线系统的场景)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。
