Abstract
To enable radio communication to be performed more favorably in a UL band of FDD when the UL band is used for both DL and UL in a time division manner. There is provided a device that includes a switching unit that switches an operation mode of an uplink band of FDD 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 in a time division manner and a control unit that gives an instruction on a first timing advance on the basis of a downlink reception timing in a downlink band of FDD corresponding to the uplink band and an instruction on a second timing advance on the basis of a downlink reception timing in the uplink band.

A device, comprising:
- a processor configured to:
- switch an operation mode of an uplink band of frequency division duplex (FDD) 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 the uplink in a time division manner;
- and
- give a first instruction on a first timing advance based on a downlink reception timing in a downlink band of the FDD corresponding to the uplink band and a second instruction on a second timing advance based on a downlink reception timing in the uplink band.
