    摘要: An apparatus and a system for transmitting channel state information acquires channel state information of a channel between a mobile terminal and two or more cooperative base stations. The apparatus quantizes the channel state information separately by using a preset single-cell codebook used for quantizing the channel between the mobile terminal and each one of the two or more cooperative base stations. The apparatus acquires united codeword indexes of the quantized channel state information in the single-cell codebook; and transmits the united codeword indexes of the quantized channel state information in the single-cell codebook.

    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.
