Interference constrained device-to-device communications [PDF]
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.

Interference-aware distributed device-to-device caching
In this paper, cache placement problem in cellular networks with device to device communications (D2D) is addressed. D2D transmission allows cellular bandwidth reuse which necessitates interference management. We propose a distributed algorithm, where the base station rewards the user terminals for caching content and helping other nearby terminals ...
