Method and system for quantized feedback rate adaptation in a communication system
Abstract:
The present invention relates to a method for adapting the feedback rate of a quantized representation of the propagation channel in a capacity-limited feedback channel. The method comprises obtaining a reference signal from an access point; deriving a rank indication, a codebook subset selection indication and a precoding matrix index based on the obtained reference signal; sending a first feedback message conveying the rank indication and the codebook subset selection indication, and sending a second feedback message conveying the precoding matrix index, to the access point; and receiving, from the access point, data precoded by a matrix derived based on the rank indication, the codebook subset selection indication and the precoding matrix index.
