摘要： A cooperative communications method for a wireless network and a corresponding apparatus. In one embodiment, the method includes: obtaining a matrix corresponding to a destination Mobile Station (MS), where the number of rows of the 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 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 matrix; performing precoding according to the precoding matrix; and performing cooperative communication according to a result of the precoding. The method of this embodiment enables the reduction or elimination of interference between users by specifying a direction matrix, and is applicable to multi-antenna MSs. A cooperative base station (BS) applicable to the foregoing method is also disclosed.

摘要： A method, a system, a Base Station (BS) and a mobile terminal device for collaborative communication are disclosed, so as to multiplex open-loop and closed-loop users and improve a utilization rate of system frequency spectrum. The method includes receiving CSI sent by a user, in which the CSI is CSI of an LOS signal of the user that is obtained by eliminating CSI of a multi-path signal. The method then obtains CSI of a closed-loop user having a channel that is orthogonal to a channel of the user, and performs pre-coding calculations by using the CSI of the LOS signal of the user and the CSI of the closed-loop user. Communication data is then sent to the user by using the result of the pre-coding calculation.
