RESOURCE ALLOCATION METHOD AND DEVICE FOR DEVICE-TO-DEVICE DIRECT COMMUNICATION IN WIRELESS COMMUNICATION SYSTEM

摘要

Disclosed is a method by which a transmission terminal transmits a signal by using device-to-device direct communication in a wireless communication system. Particularly, the method comprises the steps of: identifying each of a plurality of resource units as a clean unit or a dirty unit; selecting one of the clean units as a transmission resource if the number of clean units is a first threshold value or more; selecting, as the transmission resource, one among the one or more dirty units from which interference that is a second critical value or more is detected if the number of clean units is less than the first threshold value; and transmitting a device-to-device direct communication signal by using the selected transmission resource.

1. A method of transmitting a signal, which is transmitted by a user equipment using device-to-device (D2D) communication in a wireless communication system, the method comprising:
classifying each of a plurality of resource units into clean units or dirty units; when the number of the clean units is equal to or greater than a first threshold, selecting one of the clean units as a transmission resource; when the number of the clean units is less than the first threshold, selecting a dirty unit from among one or more dirty units at which interference equal to or greater than a second threshold is detected as the transmission resource; and transmitting a D2D signal using the selected transmission resource.
