METHOD FOR TRANSMITTING BEAM FORMING INFORMATION AND A METHOD FOR TRACKING POSITION OF A MOBILE STATION IN MULTI INPUT MULTI OUTPUT SYSTEM USING CODEBOOK-BASED BEAM FORMING SCHEME

摘要

A method for transmitting feedback information in a codebook-based multiple-input multiple-output (MIMO) system is disclosed. For example, a method for transmitting beamforming information in a MIMO system using a codebook-based beamforming scheme includes receiving a signal and estimating a reception channel, and transmitting beamforming information selected through the estimated channel information from a codebook which is updated using phase shift matrices having a phase value as a parameter and using previous beamforming information.
