Abstract
When a UE 100-2 (a reception-side UE) that performs D2D communication by using UL radio resource switches communication modes between cellular communication and the D2D communication, if DL subframe in which data reception of the cellular communication should be performed and the UL subframe in which data reception of the D2D communication should be performed at least partially overlap on a time axis, then the UE 100-2 performs data reception in one subframe, out of the overlapping two subframes.
Claims9
A user terminal, comprising:
- a controller configured to control performing Device to Device (D2D) communication, that is direct device-to-device communication, by use of a frame structure defined for uplink communication and downlink communication;
- and
- a receiver configured to perform a reception of the downlink communication without performing a reception of the D2D communication when at least a part of a reception time of the D2D communication and a reception time of the downlink communication overlap.
A user terminal, comprising:
- a controller configured to control performing Device to Device (D2D) communication, that is direct device-to-device communication, by use of a frame structure defined for uplink communication and downlink communication;
- and
- a transmitter configured to perform a transmission of the uplink communication without performing a transmission of the D2D communication when at least a part of a transmission time of the D2D communication and a transmission time of the uplink communication overlap.
A user terminal, comprising:
- a controller configured to control performing Device to Device (D2D) communication, that is direct device-to-device communication, by use of a frame structure defined for uplink communication and downlink communication;
- and
- a transmitter configured to perform a transmission of the D2D communication, wherein
- the transmitter does not perform the transmission of the D2D communication when at least a part of a transmission time of the D2D communication and a transmission time of the uplink communication overlap, and
- the transmitter does perform the transmission of the D2D communication when the transmission time of the D2D communication and the transmission time of the uplink communication do not overlap.
A user terminal, comprising:
- a controller configured to control performing Device to Device (D2D) communication, that is direct device-to-device communication, by use of a frame structure defined for uplink communication and downlink communication;
- and
- a transmitter configured to transmit to a base station, information indicating whether the user terminal supports simultaneous transmission of the uplink communication and the D2D communication.
