Abstract: The wireless communication comprises: transmitting downlink control information (DCI) from a transmission point to an UE for the enabled TB and the disabled TB, wherein the DCI comprises a 8-value indicator to indicate CoMP states for the enabled TB in conjunction with the new data indicator (NDI) of the disabled TB; if the NDI of the enabled TB is untoggled or the value of the 8-value indicator for the enabled TB is equal to 0, 1, 2, or 3, the UE using the NDI of the disabled TB to select a CoMP state from a first CoMP state and a second CoMP state; and if the NDI of the enabled TB is toggled and the value of the 8-value indicator is 4, 5, 6, or 7, the UE obtaining the information of whether the enabled TB is initial transmission or retransmission based on the NDI of the disabled TB.

Abstract: The present disclosure provides a method of generating codebook in a wireless communication system with multiple antenna arrays, as well as a wireless communication system, base station and terminal using the codebook for communication. The method comprises steps of: providing a basic codebook which contains multiple pre-coding matrices; and assigning phase offsets to certain pre-coding matrices in the basic codebook to form a codebook with phase offset. The feedback overhead from a client to a base station side is reduced and a good precision of feedback for multi-antenna array is kept by applying the method of generating codebook and using the generated codebook in the wireless communication system, base station and terminal.
