Peer-to-peer communications in a cellular network

This paper describes a practical peer-to-peer (P2P) communication architecture applied to the conventional cellular network. It enables efficient coexistence of P2P connections with cellular connections while sharing the same wireless spectrum. The design achieves both proximity discovery and P2P communication under a cellular architecture with a particular emphasis on building an RF blueprint that reflects the RF relationship between devices to ensure power and spectral efficiency, as well as interference and quality of service control of P2P communications.
