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
在5G NR(New Radio，新无线)系统中,无论是基站还是终端设备，均将会配置多个天线面板(Panel)。NR Rel-16标准已经可以支持基站通过多个天线面板同时发送无线信号，但是终端设备即使配置了多个天线面板也只支持基于天线面板选择的传输，即同一时刻只允许在一个天线面板上进行无线发送。在5G NR系统的未来演进中，为了提高系统容量，在基站和终端设备上都支持多个天线面板上同时发送无线信号是一个重要的技术方向。
发明内容
发明人通过研究发现，如何支持多个信号的传输是需要解决的关键问题。
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，并取得类似在上下行链路中的技术效果。此外，不同场景(包括但不限于下行链路，上行链路和伴随链路)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。
