Interference-Aware Dynamic Resource Allocation for D2D Proximity Services with Beamforming Support

We propose a low-overhead interference-aware approach to spectrally efficient, fully distributed dynamic resource allocation with beamforming support for unassisted broadcast and unicast device-to-device communications. A resource may only be allocated for transmission over a link if a) the transmitter is guaranteed to not cause excessive interference at any scheduled receivers, and b) the total interference caused by all scheduled transmitters can be handled by the receiver. In order to determine whether a resource satisfies these interference constraints, information derived from physical layer measurements (rather than geometry or network topology) is periodically exchanged among neighbors. Support of beamforming antennas is achieved in a straightforward manner by taking into account the optimal array configuration when performing such measurements.
