METHOD FOR TRANSMITTING AND RECEIVING SCHEDULING GRANT IN WIRELESS COMMUNICATION SYSTEM SUPPORTING DEVICE-TO-DEVICE COMMUNICATION, AND DEVICE FOR SAME

摘要

The present invention discloses a method for transmitting a synchronization signal and a synchronization channel in a wireless communication system supporting Device-to-Device (D2D) communication; and an apparatus for the method. More specifically, a method for transmitting a D2D synchronization signal and a D2D synchronization channel in a wireless communication system supporting D2D communication comprises mapping the D2D synchronization signal and the D2D synchronization channel to a physical resource; and transmitting the mapped D2D synchronization signal and D2D synchronization channel to a UE, wherein the D2D synchronization signal is mapped to 64 subcarriers in the frequency domain, and the D2D synchronization channel is mapped to the same resource block with the D2D synchronization signal.

1. In a wireless communication system supporting Device-to-Device (D2D) communication, a method for transmitting an SA (Scheduling Assignment), comprising:
receiving, by a first user equipment (UE), resource configuration information for an SA resource pool with which the first UE transmits the SA and a data resource pool with which the first UE transmits data from an eNB; transmitting, by the first UE, an SA 1 to a second UE by mapping the SA 1 to a specific resource region within the SA resource pool; and transmitting, by the first UE, an SA 2 and data to the second UE by mapping the SA 2 and the data to a specific resource region within the data resource pool, wherein the SA includes the SA 1 and the SA 2.
