Abstract:
Systems, methods and apparatus are provided for scheduling resources in Orthogonal Frequency-Division Multiple Access (OFDMA) communication networks for “direct link” or peer-to-peer communications among stations operating therein so that OFDMA resources can be allocated to a transmitter station for a peer-to-peer communication session with a receiver station such that near-far issues caused by peer-to-peer communication are reduced/avoided. The disclosed technologies can prevent peer-to-peer communication links using different sub-channels within the same time slot from creating near-far issues for other receiver stations that are within communication range.
