Abstract  Abstract

PROBLEM TO BE SOLVED: To provide D2D communications which can reduce demand for high data throughput or a high load amount of a mobile device to a network.

SOLUTION: UE transmits a D2D discovery state message as a part of an intra-network communication session. The D2D discovery state message indicates the start or stop of a D2D discovery operation in the UE and also indicates whether the UE announces or monitors as a part of the D2D discovery operation. The D2D discovery operation establishes a D2D communication session at least partially between the UE and one or more other UEs. The UE transmits a D2D discovery signal for reception at the one or more other UEs as a part of the D2D discovery operation. The UE can transmit and receive D2D packets via a direct link to a second UE as a part of the D2D communication session.
