MOBILE TERMINAL APPARATUS, BASE STATION APPARATUS, COMMUNICATION SYSTEM, AND COMMUNICATION METHOD

摘要

This invention mainly relates to a feedback control and a precoding control in a communication system that transmits a plurality of transmission path status measurement reference signals, and allows adaptive controls to be efficiently performed. A mobile terminal measures, based on a first transmission path status measurement reference signal and a second transmission path status measurement reference signal that is different from the first transmission path status measurement reference signal, a first transmission path status and a second transmission path status, and generates, based on the first transmission path status and the second transmission path status, a plurality of pieces of precoding information as feedback information that is to be fed back to a base station.
