Abstract
Disclosed is a method for determining, by a terminal, a transmission resource pool in device-to-device (D2D) communication. The method for determining a transmission resource pool comprises the steps of: indexing resource blocks within a resource block pool; and mapping the indexed resource blocks to physical resource blocks, wherein the indexed resource blocks are arranged in order of increasing resource block index, the resource block pool is used to transmit D2D signals, and information about the configuration of the resource block pool can be indicated by upper layer signaling.

1-14. (canceled)
A method for transmitting a device-to-device (D2D) signal by a user equipment (UE) in D2D communication, the method comprising:
- performing frequency hopping to indexes of physical resource blocks (PRBs) in a resource block pool based on a predefined hopping pattern,
- wherein the PRBs in the resource block pool is used for transmitting the D2D signal;
- transmitting the D2D signal based on the indexes of PRBs,
- wherein the resource block pool includes two resource regions,
- wherein the two resource regions are obtained based on an index of a first PRB of the resource block pool and an index of a last PRB of the resource block pool, and
- wherein the indexes of the first and the last PRB are informed by higher layer signaling.
A communication device for transmitting a device-to-device (D2D) signal in D2D communication, the communication device comprising:
- a memory;
- and
- a processor connected with the memory;
- wherein the processor is configured to control to:
- perform frequency hopping to indexes of physical resource blocks (PRBs) in a resource block pool based on a predefined hopping pattern,
- wherein the PRBs in the resource block pool is used for transmitting the D2D signal;
- transmitting the D2D signal based on the indexes of PRBs,
- wherein the resource block pool includes two resource regions,
- wherein the two resource regions are obtained based on an index of a first PRB of the resource block pool and an index of a last PRB of the resource block pool, and
- wherein the indexes of the first and the last PRB are informed by higher layer signaling.
