Abstract:
Embodiments of the present invention disclose an information transmission method and equipment based on CoMP transmission. In the method, a user equipment determines a main transmission point. The user equipment determines RANK information of the main transmission point as well as channel state information corresponding to the RANK information. The user equipment sends the RANK information of the main transmission point and the channel state information to a network side equipment. In the embodiments of the present invention, the UE reports channel state information of limited RANK of every transmission point, channel state information of unlimited RANK of the main transmission point, and relative phase information between the transmission points, etc., to the network side equipment, thereby helping the network side to better implement flexible selection and dynamic switchover of transmission schemes. Moreover, it does not notably increase feedback expenses for the UE.
