METHOD FOR OBTAINING SYNCHRONIZATION FOR DEVICE-TO-DEVICE COMMUNICATION BETWEEN USER EQUIPMENT INSIDE COVERAGE AREA AND USER EQUIPMENT OUTSIDE OF COVERAGE AREA IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS FOR SAME
METHOD FOR OBTAINING SYNCHRONIZATION FOR DEVICE-TO-DEVICE COMMUNICATION BETWEEN USER EQUIPMENT INSIDE COVERAGE AREA AND USER EQUIPMENT OUTSIDE OF COVERAGE AREA IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS FOR SAME
In the present application, a method in which a first terminal inside a base station coverage in a wireless communication system performs direct communication between a second terminal outside the coverage and a terminal is disclosed. Specifically, the method includes the steps of dividing a specific time unit for direct communication between the terminals into a plurality of candidate intervals; And transmitting a reference signal for obtaining synchronization to the second terminal when a random number is generated in one of the candidate intervals and is greater than or equal to a threshold value corresponding to the inside of the coverage, and corresponding to the inside of the coverage. The threshold value is characterized in that it is smaller than the threshold value corresponding to the outside of the coverage.
