摘要： A feedback method for a multi-antenna system is disclosed. The feedback method for use in the multi-antenna system can reduce an amount of transmission (Tx) feedback information associated with a precoding matrix (i.e., a codebook). For example, a single codebook may include precoding matrixes associated with several ranks. A basic matrix constructing the precoding matrix is extended to a frequency axis, such that it can be used as a Cyclic Delay Diversity (CDD) structure.

摘要： A method and apparatus for performing virtual multiple antenna transmission using feedback information in a closed-loop multiple antenna system is provided. Virtual multiple antenna control information is fed back from a receiving end that has determined the virtual multiple antenna control information taking into consideration a communication condition of a transmitting end. Virtual multiple antenna transmission is performed in uplink using the feedback information. The transmitting end may also primarily determine at least part of the virtual antenna control information and transmit the determined information to the receiving end. This method allows adaptive virtual multiple antenna transmission suitable for a channel condition in closed-loop uplink, thereby improving the communication performance.
