Abstract
The present invention relates to the field of communications. Disclosed are a CoMP transmission feedback method, device and system, the method comprising: determining an inter-mode reference relationship between at least two configured modes according to configuration information transmitted by a base station (s); at each feedback instance. determining the parameter in the current mode via the parameter in a reference mode and according to the reference relationship between modes (s); and feeding back the channel state information containing the parameter in the current mode according to the configuration of the current mode (s). The present invention realizes the sharing of pre-coding matrix indicator/rank indicator (PMI/RI) information among a plurality of channel quality indicators (CQIs) having different interference assumptions, and realizes the sharing of RI information among different transmission points, thus achieving a dependency relationship among a plurality of feedback modes.
