Claim:
1. A method for feeding back channel state information, comprising: 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 or of priorities between a plurality of CSIs or a plurality of colliding CSIs, wherein, the base station notifies the terminal by at least one of the following ways: a terminal dedicated high layer signaling, a physical downlink control signaling and a preset rule, wherein, the step of a base station notifying a terminal of transmission resources used for transmitting colliding CSIs comprises: the base station configuring PUSCH resources used for transmitting colliding CSIs through the terminal dedicated high layer signaling, and indicating the terminal to: on subframes with CSI collision, if no aperiodic triggered feedback and no PUSCH transmission exist, feed back all or part of the colliding CSIs through the PUSCH resources; and if the aperiodic triggered feedback and the PUSCH transmission exist, transmit aperiodic triggered CSIs or all or part of the colliding CSIs or CSIs with a highest priority according to aperiodic triggering and PUSCH transmission resources, or, wherein, the step of a base station notifying a terminal of transmission resources used for transmitting colliding CSIs comprises: the base station configuring a plurality of sets of PUSCH resources used for transmitting colliding CSIs through the terminal dedicated high layer signaling, and indicating the terminal to: on subframes with CSI collision, if no aperiodic triggered feedback and no PUSCH transmission exist, feed back all or part of the colliding CSIs through one set of the plurality of sets of PUSCH resources; and when the aperiodic triggered feedback or the PUSCH transmission exist, transmit aperiodic triggered CSIs or all or part of the colliding CSIs or CSIs with the highest priority according to aperiodic triggering and PUSCH transmission resources.
