Title:
TERMINAL DEVICE, BASE STATION DEVICE, COMMUNICATIONS METHOD, AND INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2014/156617
Kind Code:
A1
Abstract:
The present invention provides a base station device, a terminal device, a communications method, and an integrated circuit that are capable of more efficient communications whereby the terminal device sends uplink signals on the basis of scheduling by the base station device. The terminal device comprises: a setting unit that makes first uplink-downlink settings, second uplink-downlink settings, and third uplink-downlink settings; a reception unit used for scheduling physical downlink shared channels in a downlink sub-frame on the basis of the third uplink-downlink settings and which monitors a physical downlink control channel having associated thereto a downlink control information format including information requesting transmission of a sounding reference signal; and a transmission unit that sends or drops the sounding reference signal and sends HARQ-ACK in response to a transmission by the physical downlink shared channel.
