摘要：
A method for transmitting feedback information in a codebook-based multiple-input multiple-output (MIMO) system is disclosed. To transmit the feedback information, a signal is received to discern channel characteristics of the received signal, and a codebook is updated using an extended matrix including a plurality of vector components and using previous feedback information. Feedback information is selected for transmission from the updated codebook in consideration of the channel characteristics of the received signal.
