Abstract
The present invention relates to a method for providing, by a first UE, which conducts a device-to-device (D2D) communication, a multimedia broadcast/multicast service (MBMS) in a wireless communication system. In particular, the method comprises steps of: receiving, by a first UE, control information for a D2D communication; and providing, by the first UE, an MBMS to a second UE which is intended for the D2D communication, wherein the MBMS is configured to be transmitted using an uplink resource.
Claims13
A method of transmitting a device to device (D2D) signal to a plurality of User Equipments (UEs) by a first user equipment (UE) in a wireless communication system, the method comprising:
- receiving D2D control information for D2D communication;
- transmitting the D2D signal including the D2D control information to a second UE among the plurality of UEs corresponding to a counterpart entity of the D2D communication;
- and
- decoding the D2D signal based on an identifier of the first UE upon receiving the D2D signal retransmitted by the BS
- wherein, if decoding is successful, the first UE determines that the D2D signal has been successfully transmitted to the second UE, and
- wherein the D2D signal is configured to be transmitted using an uplink resource.
A first user equipment (UE) for transmitting a device to device (D2D) signal to a plurality of User Equipments (UEs) in a wireless communication system, the first UE comprising:
- a radio frequency (RF) unit;
- and
- a processor, wherein the processor is configured to
- receive a device to device (D2D) signal control information for D2D communication
- transmit the D2D signal including the D2D control information to a second UE among the plurality of UEs corresponding to a counterpart entity of the D2D communication, and
- decode the D2D signal based on an identifier of the first UE upon receiving the D2D signal retransmitted by the BS,
- wherein, if decoding is successful, the first UE determines that the D2D signal has been successfully transmitted to the second UE, and
- wherein the D2D signal is configured to be transmitted using an uplink resource.
