Abstract
[Object] 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. [Solution] There is provided a device including: a switching unit configured to switch 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 configured to give 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 switching unit 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 uplink in a time division manner;
- and
- a control unit configured to give 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 switching unit configured to switch 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 configured to synchronize a downlink transmission timing in a downlink band of FDD corresponding to the uplink band with a downlink transmission timing in the uplink band when the operation mode is the second mode.
A device comprising:
- an acquisition unit configured to acquire information indicating a switch of 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 configured to perform a process for uplink transmission in the uplink band when the operation mode is the first mode, and perform a process for downlink reception and uplink transmission in the uplink band when the operation mode is the second mode,
- wherein the control unit adjusts an uplink transmission timing in the uplink band on the basis of a downlink reception timing in a downlink band of FDD corresponding to the uplink band regardless of whether the operation mode is the first mode or the second mode.
