可选地，若所述第一下行信号为DMRS，所述DMRS可以为数据信道的DMRS，即所述DMRS可以用于数据信道的相关解调，或者也可以为控制信道的DMRS，即所述DMRS可以用于控制信道的相关解调。
在本申请实施例中，所述第一下行信号的第一端口集合之间是准同址的，所述第一端口集合包括用于传输所述第一下行信号的部分或全部端口。例如，若所述第一下行信号为DMRS，用于传输所述DMRS的天线端口包括端口5，端口6，端口7和端口8，那么所述DMRS的第一端口集合可以包括端口5，端口6，端口7和端口8中的部分或全部。或者若所述第一下行信号为CSI-RS，用于传输CSI-RS的天线端口包括端口0～端口3，那么CSI-RS的第一端口集合包括端口0～端口3中的部分或全部。
在具体实现时，可以设置第一端口集合对应相同的QCL ID，第一端口集合和其他端口分别对应不同的QCL ID。例如，所述第一下行信号为 DMRS，用于传输所述DMRS的天线端口包括端口5，端口6，端口7和端口8，第一端口集合包括端口5和端口6，即端口5和端口6准同址，端口7和端口8准同址，那么可以设置端口5和端口6对于相同的QCL ID，端口7和端口8对于另一个QCL ID，从而终端设备可以根据QCL ID确定哪些端口是准同址的。
可选的，若所述第一下行信号的第一端口集合和第二下行信号的第二端口集合准同址，所述第一下行信号的第一端口集合和所述第二下行信号的第二端口集合可以对应相同的QCL ID，那么所述终端设备可以根据QCL ID即可确定哪些端口是准同址的，QCL ID可以由多个下行信号共同使用，因此，可以通过QCL ID指示与所述第一下行信号准同址的多个下行信号，因此，相较于网络设备通过高层信令或下行控制信息(Down Control Information，DCI)给终端设备配置与第一下行信号准同址的下行信号的索引(Index)信息，降低了信令开销，增加了QCL指示方式的灵活性。
在本申请实施例中，作为示例而非限定，所述QCL ID可以为Cell ID，波束ID，或同步信号块的时间索引，或者RS ID，即所述QCL ID可以为同步信号或同步信号块携带的Cell ID，或者所述QCL ID也可以为发送或接收下行信号采用的波束的波束ID，所述QCL ID为用于生成RS序列的RS ID，当然，所述QCL ID也可以为其他标识信息，本申请实施例对于QCL ID的具体标识方式不作限定。

因此，在本申请实施例中，所述第二下行信号可以为CSI-RS，或同步信号块，或同步信号，或同步信道，或相位跟踪参考信号(Phase Tracking Reference Signal，PT-RS)，或其他下行信号，本申请实施例对此不作限定。
