Abstract
At the beginning of every epoch the invention estimates the average traffic demand from cellular and device-to-device traffic in each sector in either DL or UL directions based on history from previous epochs. It partitions the network into interfering sectors and employing device-to-device traffic to determine the dynamic fractional frequency reuse FFR patterns for each of these clusters. Then, in every frame, for the set of sectors co-located at the same base station and instantaneous traffic demands, the invention solves the problem of device-to-device traffic placement and scheduling of cellular and device-to-device traffic jointly.

A method comprising the steps of:
- providing resource management in cellular networks responsive to device-to-device communication capability in time division and frequency division duplexing wireless communication systems, the providing comprising:
- estimating, at the beginning of every epoch lasting several tens of frames, an average traffic or resource demand from cellular and device-to-device traffic in each sector of the network based on history from previous epochs;
- partitioning the network into disjoint small clusters of interfering sectors called cross sectors and utilizing device-to-device traffic to determine dynamic fractional frequency reuse patterns for downlink and uplink jointly for each of the clusters in a distributed and localized manner;
- and
- determining, responsive to the determined fractional frequency reuse patterns, resources of operation for each sector in the cluster in downlink and uplink directions.
