APPARATUS AND METHOD FOR TRANSMITTING/RECEIVING FEEDBACK INFORMATION IN A MOBILE COMMUNICATION SYSTEM USING ARRAY ANTENNAS |
摘要 |
<p>Provided is a method for transmitting feedback information by a receiver in a mobile communication system that performs multiplexing transmission using array antennas. The method includes determining a weight set for maximizing a data rate among at least one weight set having, as its elements, multiple orthonormal weight vectors, based on a fading channel estimated from a pilot channel of received data; estimating channel state information corresponding to a weight vector of the determined weight set; and generating and transmitting feedback information including an index of the determined weight set, the selected weight vector information, and the channel state information corresponding to the weight vector.</p> |
