Terminal apparatus, feedback control method, base station, pairing control method, program, and wireless communication system

摘要

Provided is a terminal apparatus including an estimation unit that estimates a channel to a base station by using a reference signal transmitted from the base station, a selection unit that selects a transmission weight desirable for down-link transmission on the channel from a plurality of transmission weight candidates in accordance with an estimation result by the estimation unit, and a feedback controller that controls feedback of the transmission weight selected by the selection unit to the base station. When the selection unit selects two transmission weights or more, the feedback controller feeds back the selected two transmission weights or more to the base station.

主权项

1. A terminal apparatus, comprising:
a wireless communication circuit that receives a reference signal and a feedback control information from a base station, the feedback control information including at least one of an index number control information, a quality standard, and an index designation information; an estimation circuit that generates an estimation result by estimating a channel to the base station by using the reference signal and the feedback control information received by the wireless communication circuit; a selection circuit that receives the estimation result from the estimation circuit and selects a plurality of transmission weights desirable for down-link transmission on the channel from a plurality of transmission weight candidates based on the estimation result, the plurality of transmission weights including the transmission weights for desired index and desired pair index; and a feedback control circuit that controls and generates feedback of the plurality of transmission weights selected by the selection circuit to the base station, wherein the feedback control circuit feeds back the selected plurality of transmission weights to the base station.
