Device and method for performing device to device communication in wireless communication system

摘要

A device and a method for performing Device to Device (D2D) communication in a wireless communication system are provided. The method includes transmitting information on a self-frequency band selected from all frequency bands for the D2D communication, to the second mobile station, receiving information on a counterpart-frequency band selected for the D2D communication, from the second mobile station, determining transmission and reception frequency bands to be used for the D2D communication, based on the information on the self-frequency band and the information on the counterpart-frequency band, transmitting data to the second mobile station in the determined transmission frequency band, and receiving data from the second mobile station in the determined reception frequency band.

主权项

1. A method of transmitting/receiving, by a first mobile station, data through device to device (D2D) communication with a second mobile station in a wireless communication system, the method comprising:
sequentially selecting remaining frequency bands other than a frequency band used within a cell in which the first mobile station is located, from among all the frequency bands for the D2D communication; transmitting information on some frequency resources allocated from the selected frequency bands to the second mobile station; receiving information on a counterpart-frequency band selected for the D2D communication from the second mobile station; determining transmission and reception frequency bands to be used for the D2D communication based on the information on the self-frequency band and the information on the counterpart-frequency band; transmitting data to the second mobile station in the determined transmission frequency band; and receiving data from the second mobile station in the determined reception frequency band, wherein an interval for transmitting the information is configured to be an integer number of times or 1/n times of an interval in which the second mobile station monitors reception of a signal transmitted by itself in one frequency band, wherein n is a positive integer.
