Interference constrained device-to-device communications [PDF]
2014 IEEE International Conference on Communications (ICC), 2014 This paper considers a scenario in which multiple device-to-device (D2D) users can reuse the uplink resources of a cellular network to transmit directly to their corresponding receivers. The aggregated interference from the D2D users is limited by applying a threshold on the allowable interference in the base station.
