The present invention provides a feedback method and a terminal apparatus of the channel state information. The method includes the UE based on the instruction information confirming the channel status information, including type 1 PMI and / or type 2 PMI and which first type PMI is an index of the precoding codebook of the first of the first precoding matrix the instructions and each of the first precoding matrix is a speed and / or are used in the mapping of the channel information of the long channel type 2, PMI indicating the index of the precoding codebook of the second of the second precoding matrix, and each of the second the precoding matrix sub-band and / or is used in the mapping of the channel information of the short-term channel, UE feeds back a first type PMI periodically on the PUCCH and feedback of the second type PMI to periodically or non-periodically on the PUSCH, or UE It includes the step of feeding back a PMI type 1 and type 2 PMI in the PUCCH. According to the present invention can improve the accuracy of channel state feedback information to the UE and the base station may dynamically select a single-user MIMO or multi-user MIMO transmission.
