Abstract
A signaling transmission method and apparatus for a Multiple-Input Multiple-Output MIMO system are provided. The method includes the following steps. Channel-Related Information CRI about a combined channel is formed according to CRI between all receiving antenna ports in a receiving network and a sending antenna port in a sending network. The CRI about the combined channel is sent to the sending network. Herein, the CRI includes one or more of the following: channel information, Channel State Information CSI, and a CSI Reference Signal CSI-RS.
