    Abstract: A method for feeding back channel state information is provided, which includes: a base station notifying a terminal of transmission resources used for transmitting a plurality of Channel State Information (CSIs) or a plurality of colliding CSIs and/or of priorities between a plurality of CSIs or a plurality of colliding CSIs. In the present document, the base station indicates the terminal on how to handle a feedback of the colliding CSIs when collision between the CSIs occurs during processes of feeding back a plurality of CSIs via a high layer signaling or a preset rule, which enables the base station and the terminal to reach a uniform feedback mechanism, and guarantees a minimum possibility of discarding CSIs, thereby solving the problem of the impact on the CoMP performance due to discarding excessive CSIs.
