Abstract
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.
