The present invention relates to communication apparatus, base station and CoMP communication method. The communication apparatus comprising: a channel estimating unit for acquiring a channel estimation value of a channel between the communication apparatus and a cell base station of a cell in which the communication apparatus is located, i.e., the channel estimation value between the communication apparatus and the cell base station; a transmitting unit for transmitting the channel estimation value or information based on the channel estimation value to the cell base station; a receiving unit for receiving coordinated multipoint (CoMP) message from the cell base station, the CoMP message indicates the CoMP transmission mode, the codebook or precoding matrix used by the cell base station, and the codebook or precoding matrix used by a coordinated base station that coordinates with the cell base station; a channel matrix forming unit for acquiring a channel matrix according to the CoMP message; and a decoding unit for decoding received signals according to the channel matrix and the CoMP message. |
