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。多天线系统提供的自由度可以用来提高传输可靠性和/或吞吐量。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增益。在NRR(release)17中,基于多个波束/TRP/panel的上行传输被支持,用于提高上行传输的可靠性。在R17中,一个UE可以被配置多个基于码本(codebook)或非码本(non-codebook)的SRS(Sounding Reference Signal,探测参考信号)资源集合,不同SRS资源集合对应不同波束/TRP/panel,用于实现多波束/TRP/panel的上行传输。
发明内容
基于多个波束/TRP/panel的上行传输可以采用时分复用的方式(即占用相互正交的时域资源),如R17中的做法,也可以采用空分复用的方式(即占用交叠的时频资源)。相比于时分复用,空分复用的实现方式更有利于提高吞吐量,特别是对于信道质量较好的用户。申请人通过研究发现,不同复用方式对DMRS(DeModulation Reference Signals,解调参考信号)端口(port)到物理资源的映射有不同需求。如何设计DMRS端口到物理资源的映射来分别满足时分复用和空分复用的需求是需要解决的问题。在空分复用的方式下如何进行DMRS端口到物理资源的映射是另一个需要解决的问题。
针对上述问题,本申请公开了一种解决方案。需要说明的是,虽然上述描述采用蜂窝网,上行传输和多波束/TRP/panel作为例子,本申请也适用于其他场景比如副链路(Sidelink)传输,下行传输和单波束/TRP/panel,并取得类似在蜂窝网,上行传输和多波束/TRP/panel中的技术效果。此外,不同场景(包括但不限于蜂窝网,副链路,上行传输,下行传输,多波束/TRP/panel和单波束/TRP/panel)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。
