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
多天线技术是3GPP(3rd Generation Partner Project,第三代合作伙伴项目)LTE(Long-term Evolution,长期演进)系统和NR(New Radio,新无线电)系统中的关键技术。通过在通信节点处,比如基站或UE(User Equipment,用户设备)处,配置多根天线来获得额外的空间自由度。多根天线通过波束赋型,形成波束指向一个特定方向来提高通信质量。当多根天线属于多个TRP(Transmitter Receiver Point,发送接收节点)/panel(天线面板)时,利用不同TRP/panel之间的空间差异,可以获得额外的分集/复用增益。在NR R(release)16中,基于多TRP的重复传输被用于提高下行物理层数据信道的传输可靠性。
发明内容
在NR R17及其后续版本中,基于多TRP/panel的传输方案将会被继续演进,其中一个重要的方面包括用于增强物理层控制信道。在3GPP RAN(Radio Access Network,无线接入网)1#103-e会议上,对同一个CORESET(COntrol REsource SET,控制资源集合)分配两个被激活的TCI(Transmission Configuration Indicator,传输配置标识)状态的方案以及两个被关联到不同CORESET的PDCCH(Physical Downlink Control Channel,物理下行控制信道)候选项(candidate)之间的合并解码方案都被通过。在NR R16中,对于在时域上交叠的PDCCH候选项,UE只需要监测其中和一个特定的CORESET具有相同的QCL(Quasi Co-Location,准共址)-typeD特性的PDCCH候选项。当一个PDCCH candidate和两个TCI状态有关时,对在时域上交叠的PDCCH候选项的监测有什么影响,是需要解决的问题。
针对上述问题,本申请公开了一种解决方案。需要说明的是,虽然上述描述采用多TRP/panel传输和控制信道的传输场景作为一个例子,本申请也适用于其他场景比如单TRP/panel传输其他物理层信道,载波聚合(Carrier Aggregation)或物联网(V2X),并取得类似在多TRP/panel传输和控制信道的传输场景中的技术效果。此外,不同场景(包括但不限于多TRP/panel传输,单TRP/panel传输,控制信道,其他物理层信道,载波聚合和物联网)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,本申请的第一节点中的实施例和实施例中的特征可以应用到第二节点中,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。
作为一个实施例,对本申请中的术语(Terminology)的解释是参考3GPP的规范协议TS36系列的定义。
