Abstract

Provided is a method for transmitting resource information for device-to-device (D2D) communication of a D2D transmission terminal in a wireless communication system, the method being characterized by comprising the steps of: receiving a resource pool configuration for D2D communication; and transmitting, to a D2D reception terminal, resource information therefor indicating the resource for a first D2D signal transmission to the D2D transmission terminal.

Claims

1. A method of transmitting resource information for device-to-device (D2D) communication in a wireless communication system, the method performed by a D2D transmission user equipment (UE) and comprising:

receiving a resource pool configuration for the D2D communication; and

transmitting, to a D2D reception UE, resource information indicating resources for first D2D signal transmission from the D2D reception UE to the D2D transmission UE.

2. The method of claim 1, wherein, when the D2D transmission UE performs the first D2D transmission, the resource information indicates radio resources that the D2D transmission UE can receive.

3. The method of claim 1, wherein the resource information indicates first radio resources for the first D2D signal transmission,

wherein the first radio resources are configured in a resource pool except second radio resources, and

wherein the second radio resources are radio resources used for second D2D signal transmission from the D2D transmission UE to the D2D reception UE.

4. The method of claim 1, wherein the resource information is mapped to a resource pool for a scheduling assignment.

5. The method of claim 1, wherein the resource information is mapped to a resource pool for D2D data.

6. The method of claim 1, wherein the resource information is transmitted using a predetermined channel and wherein the resources are determined based on a D2D UE identifier (ID).

7. The method of claim 1, wherein the resource information is configured to be cyclic redundancy check (CRC) masked with a D2D UE identifier (ID).

8. The method of claim 1, wherein the resource information is configured to include a field associated with identifier (ID) information of the D2D transmission UE.

9. The method of claim 1, wherein the resource information is configured to be transmitted with control information for either or both of the first D2D signal transmission and the second D2D signal transmission.

10. A device-to-device (D2D) transmission user equipment (UE) for transmitting resource information for D2D communication in a wireless communication system, the D2D transmission UE comprising:

a radio frequency unit; and

a processor,

wherein the processor is configured to receive a resource pool configuration for the D2D communication and transmit, to a D2D reception UE, resource information indicating resources for first D2D signal transmission from the D2D reception UE to the D2D transmission UE.
