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

摘要

A terminal apparatus communicates with a base-station apparatus. The terminal apparatus reports partial precoder information that specifies at least one preferred candidate from among a plurality of candidates of precoders, where the partial precoder information is reported together with data from the terminal apparatus via a channel for use in data transmission. The partial precoder information is also rearranged with a same ordering for the data in a case that the partial precoder information is to be aperiodically reported. Further, the partial precoder information is rearranged with a different ordering from the ordering for the data in a case that the partial precoder information is to be periodically reported.

1. A terminal apparatus configured to communicate with a base-station apparatus, the terminal apparatus comprising:
a transmitting circuit configured to report partial precoder information that specifies at least one preferred candidate from among a plurality of candidates of precoders, the partial precoder information being reported together with data from the terminal apparatus via a channel for use in data transmission, wherein the partial precoder information is rearranged with a same ordering for the data in a case that the partial precoder information is to be aperiodically reported, and the partial precoder information is rearranged with a different ordering from the ordering for the data in a case that the partial precoder information is to be periodically reported.
