D2D SIGNAL TRANSMISSION METHOD AND USER EQUIPMENT

摘要

The present invention provides a method whereby user equipment located outside network coverage or in partial network coverage performs device-to-device (D2D) communication. The user equipment, which has a D2D signal to transmit, can send a request for resource allocation for the transmission of the D2D signal to user equipment configured as a cluster head, or become a cluster head itself. The user equipment, which has the D2D signal to transmit, can transmit the D2D signal according to the resource allocation by the cluster head or resource allocation performed by becoming a cluster head itself. Other user equipment receives the D2D signal by receiving or overhearing information on the resource allocation from the cluster head.

1. A method for transmitting a device-to-device (D2D) signal by a user equipment (UE) positioned outside a network, the method comprising:
transmitting a first message to a cluster head of a cluster containing a plurality of UEs using a preconfigured resource; receiving, from the cluster head, a second message containing control information for transmission of the D2D signal; and transmitting the D2D signal based on the control information.
