Abstract
Disclosed according to various embodiments of the present invention are a method and a device for preforming device-to-device (D2D) relay communication. Disclosed are a method and a device for performing device-to-device (D2D) relay communication, the method comprising the steps of: receiving, from second UE, a signal including relay request information; transmitting a response signal to the second UE if destination UE corresponding to destination UE ID included in the relay request information has been found; and transmitting a relay signal to the destination UE.
Claims11
A method of performing device-to-device (D2D) relay communication by a first user equipment (UE) in a wireless communication system, the method comprising:
- receiving a signal including relay request information from a second UE;
- when a destination UE corresponding to a destination UE ID included in the relay request information is discovered, transmitting a response signal to the second UE;
- and
- transmitting a relay signal to the destination UE,
- wherein the signal includes a first field indicating whether the relay information is included,
- wherein when the first field is set to a first value, the relay request information includes the destination UE ID that the second UE desires to discover, and
- wherein when the first field is set to a second value, the relay request information includes a UE ID of the second UE.
A user equipment (UE) for performing device-to-device (D2D) relay communication in a wireless communication system, the UE comprising:
- a transceiver;
- and
- a processor configured to:
- control the transceiver to receive a signal including relay request information from a transmitting UE;
- control the transceiver to transmit a response signal to the transmitting UE when a destination UE corresponding to a destination UE ID included in the relay request information is discovered;
- and
- control the transceiver to transmit a relay signal to the destination UE,
- wherein the signal includes a first field indicating whether the relay information is included,
- wherein when the first field is set to a first value, the relay request information includes the destination UE ID that the second UE desires to discover, and
- wherein when the first field is set to a second value, the relay request information includes a UE ID of the second UE.
