Abstract
A method includes detecting a device to device (D2D) synchronization signal of a neighbor base station, transmitted from at least one other UE associated with the neighbor base station through a transceiver, determining at least one UE receive (RX) resource pool configured by the neighbor base station based on the D2D synchronization signal of the neighbor base station, and monitoring a D2D discovery or communication signal transmitted from the at least one other UE according to the at least one UE RX resource pool through the transceiver. A method includes determining at least one UE RX resource pool for at least one device associated with a base station, each UE RX resource pool comprising a repetition of a Scheduling Assignment (SA) pool and a data pool with a scheduling cycle, the SA pool comprising a SA bitmap, and the data pool comprising at least one repeated data bitmap.
