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令的设计方案和装置。
背景技术
在5G NR(New Radio，新无线)中，大规模(Massive)MIMO(Multi-Input Multi-Output)是一个重点技术。大规模MIMO中，多个天线通过波束赋型(Beamforming)，形成较窄的波束指向一个特定方向来提高通信质量。在5G NR中，定义了用于PDCCH(Physical Downlink Control Channel，物理下行控制信道)监测的CORESET(Control Resource Set，控制资源集合)以及搜索空间集合(Search Space Set),每个搜索空间集合都会关联到一个CORESET，CORESE中的PDCCH备选在被接收时会采用一个TCI(Transmission Configuration Indication，传输配置指示)所对应的空间接收参数。
在NR R17的讨论，针对Multi-TRP(发送接收节点)的场景，为了增加PDCCH的可靠性,终端可以将两个关联到一起搜索空间集合中的两个PDCCH备选(Candidate)进行联合检测以提高性能，而两个PDCCH备选可以通过两个TRP分别采用不同的波束发送。与此同时，在3GPP RAN(Radio Access Network，无线接入网)1#103e次会议中，采用物理层信令同时更新控制信道和数据信道的波束的技术已被采纳。
发明内容
发明人通过研究发现，目前NR系统中并不支持M-TRP和联合(Unified)的TCI一起使用，即当Unified的TCI被更新到PDCCH或者PDSCH(Physical Downlink Shared Channel，物理下行共享信道)的接收时，并没有考虑M-TRP下通过两个CORESET池中的PDCCH备选联合发送PDCCH的场景。
针对上述问题，本申请公开了一种解决方案。需要说明的是，虽然上述描述采用大规模MIMO和基于波束的通信场景作为例子，本申请也适用于其他场景比如LTE多天线系统，并取得类似在大尺度MIMO和基于波束的通信场景中的技术效果。此外，不同场景(包括但不限于大规模MIMO，基于波束的通信和LTE多天线系统)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，本申请的任一节点中的实施例和实施例中的特征可以应用到其他任一节点中，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。
进一步的，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TS(Technical Specification)36系列、TS38系列、TS37系列中的定义。
