a radio communication system which includes a base station apparatus and terminal apparatuses and performs TDD two-way communications using an OFDM signal including subcarriers in a downstream communication from the base station apparatus to each terminal apparatus, and an FH signal having the same frequency band as that of the subcarriers in an upstream communication from the each terminal apparatus to the base station apparatus, the each terminal apparatus estimates transmission channel characteristics of the subcarriers based on the OFDM signal received, transmits an estimation result of the estimation unit to the base station apparatus, and the base station apparatus assigns, to the each terminal apparatus, at least one of subcarriers to be used in the downstream communication of the subcarriers and a hopping pattern to be used in the upstream communication, based on the estimation result transmitted from the each terminal apparatus.
A radio communication system which includes a base station apparatus and terminal apparatuses and performs TDD (Time Division Duplex) two-way communications using an OFDM (Orthogonal Frequency Division Multiplexing) signal including all or some of a plurality of subcarriers in a downstream communication from the base station apparatus to each of the terminal apparatuses, and an FH (Frequency Hopping) signal having the same frequency band as that of the subcarriers in an upstream communication from the each of the terminal apparatuses to the base station apparatus, the each of the terminal apparatuses comprising:
