DATA COMMUNICATION IN A WIRELESS COMMUNICATION SYSTEM USING SPACE-TIME CODING |
摘要 |
A method of controlling data communication in a wireless communication system comprises measuring channel quality from data received from a base station having multiple antennas, wherein the base station and a mobile station are in a closed loop space-time coding (STC) communication. The method also comprises determining a first weight matrix based on a number of the multiple antennas of the base station, the weight matrix comprising weight elements. The method also comprises determining a second weight matrix from the first weight matrix in response to a predetermined condition, wherein the second weight matrix is associated with controlling data output using the multiple antennas of the base station for subsequent transmission. The method also comprises providing a number of STC outputs to the base station, wherein the number of STC outputs is associated with the second weight matrix.
