TERMINAL APPARATUS, BASE STATION APPARATUS, RECEPTION METHOD AND TRANSMISSION METHOD

摘要

Provided is a terminal apparatus that, when two terminals having mutually different subframe structure patterns are coexistent, can suppress DCI scheduling constraints of those terminals in a base station. In a terminal (200), a signal separation unit (203) separates, from a received signal, both a response signal assigned to a first resource determined on the basis of a number of resources associated with the first subframes in which the signal was received and downstream control information assigned to a second resource. It should be noted that at a timing when both a first structure pattern that has been set in the terminal (200) and a second structure pattern that has been set in another terminal that cannot change the setting of the structure pattern are the first subframes, the signal separation unit (203) uses a number of resources associated with the first subframes of the second structure pattern.

1. A terminal apparatus capable of changing setting of a configuration pattern of subframes which make up a single frame to one of a plurality of configuration patterns including a first subframe used for downlink communication and a second subframe used for uplink communication, the terminal apparatus comprising:
a receiving section that receives a signal transmitted from a base station apparatus; and a demultiplexing section that demultiplexes the signal into a response signal assigned to a first resource identified based on a number of resources associated with the first subframe in which the signal has been received, and downlink control information assigned to a second resource, while a number of resources to which a response signal for uplink data is assigned is associated with the first subframe included in the configuration pattern, wherein when timing of a first configuration pattern set in the terminal apparatus and a second configuration pattern set in another terminal apparatus whose setting of a configuration pattern cannot be changed is the first subframe, the demultiplexing section uses a number of resources associated with the first subframe of the second configuration pattern.
