The present invention relates to the field of communication technologies, and in particular, to a precoding method in cooperative communication and an apparatus. The method includes: obtaining a direction matrix corresponding to a destination Mobile Station (MS), where the number of rows of the direction matrix depends on the total number of antennas of MSs in a cooperative area and the number of antennas of the destination MS, and the number of columns of the direction matrix depends on the number of code streams sent to the destination MS; calculating a precoding matrix according to local Channel State Information (CSI) and the direction matrix; and performing precoding according to the precoding matrix, and performing cooperative communication. The method in this embodiment enables the eliminating of interference between users by specifying a direction matrix, and is applicable to multi-antenna MSs. A cooperative BS applicable to the foregoing method is also disclosed. |
