Abstract
Disclosed is a method for minimizing feedback overhead in a multi-input multi-output (MIMO) communication method using multiple transmission and reception antennas. In particular, a method for minimizing feedback overhead in a multi-input multi-output (MIMO) communication system by using spatial channel covariance, as explicit channel status information (CSI) feedback method is disclosed.
Claims10
A method for performing feedback in a multi-antenna system, the method comprising:
- measuring, by a reception end, a spatial channel of the multi-antenna system;
- calculating a spatial channel covariance by using the measured spatial channel;
- determining feedback information from the calculated spatial channel covariance;
- and
- transmitting the determined feedback information to a transmission end.
