Proximity discovery for device-to-device communications over a cellular network
IEEE Communications Magazine(2014)
Abstract
This article first reviews the proximity discovery techniques used in most device-to-device communication systems. The associated issues when applied to a cellular network and the potential solutions are then addressed. We propose a unified discovery design for full, partial, and off-network coverage scenarios. We discuss the advantages and disadvantages of packet and signature-based discovery sch...
