US 10,375,661 B2 · Method for transmitting synchronization signal for D2D communication in wireless communication system and apparatus therefor

Abstract

The present invention relates to a method and an apparatus for transmitting a device-to-device (D2D) synchronization signal of a first terminal in a wireless communication system. Specifically, the method comprises the steps of: receiving a radio resource setting for D2D communication; and transmitting a D2D synchronization signal to a second radio resource which corresponds to a specific index, other than a first radio resource, from among a plurality of radio resource setting-based D2D radio resources, wherein the first radio resource is defined to be used for wide area network (WAN) based communication.

Dependent claims

A method for receiving a device-to-device (D2D) synchronization signal by a D2D terminal in a wireless communication system, the method comprising:

receiving information related to radio resource configuration for D2D communication,
wherein the information related to radio resource configuration comprises information for receiving the D2D synchronization signal;
receiving the D2D synchronization signal based on the information related to radio resource configuration;
deriving a subframe index through which the D2D synchronization signal is transmitted from a sequence repetition pattern of the D2D synchronization signal;
and
deriving a root sequence index of the D2D synchronization signal from the subframe index.
