Method and apparatus for the transmission of device to device discovery signal between base stations in wirelss cellular communication system

The present invention relates to a method and a device used in a wireless cellular communication system to transmit end-to-end terminal discovery signals between terminals in the range of a base station. The method includes the steps of: acquiring the adjacent base station information about another base station near the base station; and transmitting the acquired adjacent base station information to a terminal to control the transmission power for the discovery signal of the terminal.
