Channel state information feedback resource assignment method and the channel state information feedback method

The present invention proposes a channel state information feedback resource allocation method, comprising: configuring a user equipment of the downlink transmission mode and a feedback mode; The downlink transmission mode configured feedback mode, to assign each user equipment for channel state information feedback required feedback resource to avoid a collision between different types of the same user equipment feedback modes occur in the same subframe; notification configured downlink transmission mode, the feedback mode and the feedback resource to the corresponding user equipment. Further, the present invention proposes a channel state information feedback method, comprising: the downlink transmission mode and the feedback mode configured by the base station, the feedback channel state information of the downlink channel to the base station; when different types between different feedback modes in the same subframe collision, the collision resolution rules according to address different types of collisions between different feedback modes occur in the same sub-frame.
