Abstract
A method for feeding back channel state information, UE and system. The method is applicable to a CoMP transmission system and includes: feeding back channel state information to a network side by way of concatenating more than one pieces of channel state indication information in a bit domain. In this way, a method for feeding back multiple pieces of CSI in the CoMP transmission may be provided. Furthermore, RI information and CQI/PMI information in the CSI may be respectively encoded and mapped, so as to ensure reliable transmission of the RI information and CQI/PMI information.
