Abstract
One embodiment of the present invention is a method for a device-to-device (D2D) terminal to transmit and receive a signal in a wireless communication system, the method comprising: receiving downlink control information (DCI) comprising resource allocation information; checking the cyclic redundancy check (CRC) of the DCI by using a D2D radio network temporary identifier (RNTI); and, if there is no error in the result of the CRC check, performing D2D communication on resources denoted in the resource allocation information, wherein if the TPC field of the DCI is a pre-set value, a downlink signal is received from a base station on resources denoted in the resource allocation information.
Claims14
A method for a device-to-device (D2D) user equipment to transceive a signal in a wireless communication system, the method comprising:
- receiving downlink control information (DCI) including resource allocation information;
- making a cyclic redundancy check (CRC) on the DCI using a D2D radio network temporary identifier (RNTI);
- and
- performing D2D communication on a resource indicated by the resource allocation information if a result of the CRC is errorless,
- wherein the resource indicated by the resource allocation information is an uplink resource allocated for D2D communication, and
- wherein the resource indicated by the resource allocation information is used for receiving a downlink signal from a base station, when a transmit power control (TPC) field value of the DCI is a preset value.
A device-to-device (D2D) user equipment device in a wireless communication system, the D2D user equipment device comprising:
- a receiver;
- and
- a processor,
- wherein the processor is configured to:
- control the receiver to receive downlink control information (DCI) including resource allocation information,
- make a cyclic redundancy check (CRC) on the DCI using a D2D radio network temporary identifier (RNTI), and
- if a result of the CRC is errorless, perform D2D communication on a resource indicated by the resource allocation information,
- wherein the resource indicated by the resource allocation information is an uplink resource allocated for D2D communication, and
- wherein the resource indicated by the resource allocation information is used for receiving a downlink signal from a base station, when a transmit power control (TPC) field value of the DCI is a preset value.
