Abstract  Abstract

PROBLEM TO BE SOLVED: To provide an apparatus and a method for UE-based D2D discovery.

SOLUTION: The present disclosure provides an eNB comprising: a D2D circuit configured to allocate a plurality of periodic discovery zones for D2D discovery each of the periodic discovery zones including a plurality of first resource blocks and a plurality of second sub-frames the D2D circuit being further configured to set a UE to use one of the periodic discovery zones in order to transmit a discovery message and sectionalizing the periodic discovery zones as a result the periodic discovery zones include at least one contention-based discovery zone available to all D2D UEs regardless of an RRC connection state; and a transmitter circuit for giving notice of the sectionalization of the periodic discovery zones by signal.
