1. A method for scheduling Orthogonal Frequency Division Multiple Access (OFDMA) resources allocated to a transmitter station for a peer-to-peer communication session with a receiver station, the method comprising:

  • transmitting, from a base station to recipient stations including the transmitter station, a request for first metric measurement information to be measured with respect to selected OFDMA resources of an OFDMA frame;

    receiving the request message at the recipient stations;

    measuring, at each of the recipient stations, first metric with respect to some of the selected OFDMA resources, and transmitting, from each of the recipient stations, a response message (RM) comprising information regarding first metric measurements with respect to some of the selected OFDMA resources, wherein the transmitted information is categorized on the basis of potential to cause near-far interference;

    processing the response messages (RMs) at the base station to determine specific ones of the some of the OFDMA resources to be allocated to the transmitter station for the peer-to-peer communication session with the receiver station, wherein the processing comprises classifying peer stations of the recipient stations including the transmitter station on the basis of their potential to cause the near-far interference to determine an updated peer station information for recipient stations including the transmitter station; and

    using the updated peer station information to determine the specific ones of the some of the OFDMA resources to be allocated to the transmitter station.
