TERMINAL APPARATUS, BASE STATION APPARATUS AND COMMUNICATION SYSTEM

摘要

A terminal apparatus includes: a channel estimating unit that receives signals of pilot channels which are allocated to respective base station antennas and are orthogonal to each other and estimates channels with the respective base station antennas based on the signals of the pilot channels; an antenna selecting/phase amount calculating unit that performs selection of a base station antenna or calculation of phase rotation amounts of the base station antennas based on a result of channel estimation by the channel estimating unit; and a transmission unit that transmits an identification of the base station antenna selected by the antenna selecting/phase amount calculating unit or the phase rotation amounts calculated by the antenna selecting/phase amount calculating unit.
