Abstract

A terminal apparatus communicates with a base station apparatus using a plurality of downlink subbands and a plurality of uplink subbands. The terminal apparatus receives, in a downlink subband, response information for an uplink data transmitted in an uplink subband in accordance with setting information which is received from the base station apparatus and indicates a relationship between the uplink subband and the downlink subband used to receive the response information, where the uplink subband being one of the plurality of uplink subbands, and where the downlink subband being one of the plurality of downlink subbands.
