Abstract
A flexible subframe is efficiently set. A base station device communicates with a mobile station device using a time division duplex system in a single cell. The base station device includes a transmitting unit that transmits first information indicating an arrangement of a first subframe, a second subframe and a third subframe in a frame, and second information indicating an arrangement of the first subframe, the second subframe, the third subframe and a fourth subframe in the frame to the mobile station device.

1-27. (canceled)
A terminal device comprising:
- a receiving circuit configure to and/or programmed to:
- receive system information associated with a first uplink-downlink configuration;
- and
- monitor a physical downlink control channel with downlink control information associated with a second uplink-downlink configuration,
- a configuring circuit configure to and/or programmed to:
- configure subframes in which the terminal device monitors the physical downlink control channel with the downlink control information;
- configure the first uplink-downlink configuration based on the system information in a case that the physical downlink control channel with the downlink control information is not detected;
- and
- configure the second uplink-downlink configuration based on the downlink control information in a case that the physical downlink control channel with the downlink control information is detected,
- wherein
- the configured subframes are included in subframes indicated by the first uplink-downlink configuration associated with the system information as subframes including resources reserved for a downlink transmission.
