Abstract: The present invention relates to a system and a method for device pairing which can pair a plurality of terminals using a brightness value change pattern. The system for device pairing according to an embodiment of the present invention comprises: an apparatus including a display; n terminals; and a server for connecting the apparatus including the display with the n terminals. The server assigns an ID to the apparatus including the display in accordance with an access request of the apparatus. The apparatus including the display calculates a brightness value change pattern corresponding to the ID, and outputs the pattern on the display. The n terminals can identify the ID after detecting the pattern outputted on the display using a proximity sensor and an illuminance sensor, transmit the ID to the server, and request an access.

Abstract: Disclosed is a method for receiving a signal of a terminal configured to perform device-to-device (D2D) communication in a wireless communication system according to an embodiment of the present invention. The method may comprises the steps of: receiving a message containing information about a specific signal from a serving base station; checking whether the specific signal is an inter-cell broadcast signal to be transmitted by a peer terminal which is served by a neighboring base station, on the basis of the information contained in the message; and receiving the inter-cell broadcast signal from the peer terminal using the information contained in the message and information about a synchronization difference between the serving base station and the neighboring base station, if the specific signal is the inter-cell broadcast signal.
