METHOD FOR TRANSMITTING SYNC SIGNALS FOR DEVICE-TO-DEVICE (D2D) COMMUNICATION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR

摘要

The present invention relates to a method and apparatus for transmitting a Device-to-Device Synchronization Signal (D2DSS) for D2D communication by a terminal in a wireless communication system and, more particularly, comprises a step of transmitting a D2DSS, wherein first root indexes associated with the D2DSS are set to be different from second root indexes associated with sync signals for a cellular communication, and the number of the first root indexes is less than the number of the second root indexes.

1. A method for transmitting a D2D (Device-to-Device) synchronization signal (D2DSS) for a D2D (Device-to-Device) communication by a user equipment in a wireless communication system, the method comprising
transmitting the synchronization signal for the D2D communication, wherein a 1st root index associated with the synchronization signal for the D2D communication is set different from a 2nd root index associated with a synchronization signal for a cellular communication and wherein the number of the 1st root indexes is smaller than that of the 2nd root indexes.
