Abstract
An Orthogonal Frequency Division Multiplexing (OFDM) communication network controls Device-to-Device (D2D) scheduling. The OFDM access point wirelessly exchanges wireless communications with a plurality of individual User Equipment (UEs) using scheduled UE resources in a shared resource range. The OFDM access point wirelessly receives a first D2D communication request for a first D2D UE and responsively schedules D2D resources for the first D2D communication request in the shared resource range. The OFDM access point detects D2D interference for one of the plurality of individual UEs and determines that the D2D interference exceeds a D2D interference threshold. The OFDM access point wirelessly receives a second D2D communication request for a second D2D UE and responsively schedules D2D resources for the second D2D communication request in a D2D dedicated resource sub-range.
