DEVICE-TO-DEVICE COMMUNICATION METHOD AND A DEVICE THEREFOR

摘要

The present invention relates to a method for performing device-to-device (D2D) communication by a first terminal and a second terminal in a wireless communication system. The method includes: receiving a D2D communication setup response message including resource region information for the D2D communication from a base station; determining, based on the resource region information, whether to switch an operation frequency band of the first terminal from a first frequency band to a second frequency band; and performing the D2D communication with the second terminal at the first frequency band or the second frequency band according to the determined result, wherein either the first frequency band or the second frequency band may be used for transmission in the D2D communication and the other may be used for reception in the D2D communication.
