METHOD OF TRANSMIT BEAMFORMING FOR MULTICASTING IN A WIRELESS COMMUNICATION SYSTEM |
摘要 |
<p>The present invention provides a method of determining a plurality of beamfbrming weights for application to multicast transmission to a plurality of users by a corresponding plurality of antennas associated with a base station. One embodiment of the method includes determining a covariance matrix associated with the plurality of users. The covariance matrix is determined based on a channel matrix and a noise-plus-interference vector associated with each user. The method also includes determining the plurality of beamforming weights based on a gradient of the covariance matrix associated with a selected one of the plurality of users and storing the plurality of beamforming weights.</p> |
