METHOD AND DEVICE FOR PROCESSING FEEDBACK IN RADIO COMMUNICATION SYSTEM

Abstract

PROBLEM TO BE SOLVED: To provide a method and device that process feedback mounted on a WTRU (Wireless Transmit Receive Unit) and comprise a step of predicting a channel matrix.

SOLUTION: An effective channel is calculated and a pre-coded matrix is selected. A feedback bit group is generated and transmitted. The feedback bit group is a non-differential or differential feedback or related to a combination of both or feedback is a binary code bit alone or a combination of a binary code bit and a non-differential feedback.
