METHOD AND APPARATUS FOR PERFORMING SYNCHRONIZATION IN DEVICE-TO-DEVICE NETWORK
First Claim
1. A method for performing synchronization by a first device in a Device-to-Device (D2D) network, the method comprising:
- detecting a synchronization signal from at least one second device during one period;
determining a phase adjustment value depending on a number of synchronization signals, which have been detected from the at least one second device during the one period;
adjusting a phase value of a first device using the phase adjustment value; and
transmitting a synchronization signal if the phase value of the first device reaches a predetermined specific value.

Abstract
A method and an apparatus for performing synchronization by a first device in a Device-to-Device (D2D) network are provided. The method includes detecting a synchronization signal from at least one second device during one period, determining a phase adjustment value depending on a number of synchronization signals, which have been detected from the at least one second device during the one period, adjusting a phase value of a first device using the phase adjustment value, and transmitting a synchronization signal if the phase value of the first device reaches a predetermined specific value.
