[Problem] To enable better wireless communications in an FDD UL band when using the UL band for both DL and UL, using time division. [Solution] Provided is a device comprising: a switching unit that switches the operation mode of an FDD uplink band between a first mode in which the uplink band is used for uplink and a second mode in which the uplink band is used for both downlink and uplink, by using time division; and a control unit that notifies a terminal device about information relating to subframes sending ACK/NACK for downlink data when the operation mode is the second mode. |
