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
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(NR,New Radio)的WI(Work Item,工作项目),开始对NR进行标准化工作。
在多发送接收节点(TRP,Transmission Reception Point)/多面板通信中,同一个信道或者信号可以通过多个波束的重复传输来增强传输可靠性。在NR Rel-16中支持了数据信道采用多个TCI(Transmission Configuration Indicator,传输配置指示)状态(state)进行重复传输,在NR Rel-17中还支持了控制信道采用多个TCI状态进行重复传输。
在NR Rel-15和Rel-16中,控制信道和数据信道采用各自的波束更新机制。然而在很多情况下,控制信道和数据信道可以采用相同的波束,上下行信道之间在很多应用场景下也存在信道互易性,可以采用相同的波束。因此,在NRRel-17标准支持了控制信道和数据信道采用相同的波束并且被同时更新波束。
发明内容
发明人通过研究发现,对于控制信道来说,控制信道备选的设计是一个关键问题。
针对上述问题,本申请公开了一种解决方案。需要说明的是,虽然上述描述采用上下行链路作为例子,本申请也适用于其他场景比如伴随链路(Sidelink),并取得类似在上下行链路中的技术效果。此外,不同场景(包括但不限于上行链路,下行链路和伴随链路)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。
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。
作为一个实施例,对本申请中的术语的解释是参考3GPP的规范协议TS38系列的定义。
作为一个实施例,对本申请中的术语的解释是参考3GPP的规范协议TS37系列的定义。
