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:

  • maintaining, at the base station, a resource allocation map comprising;

    particular OFDMA resources of an OFDMA frame that have been allocated to particular stations; and

    generating, at a base station, a request for information with respect to selected OFDMA resources;

    receiving at the base station, a resource request message (RRM) from the transmitter station to request allocation of some of the OFDMA resources for the peer-to-peer communication session with the receiver station; and

    processing, at the base station, to determine specific ones of the OFDMA resources to be allocated to the transmitter station for the peer-to-peer communication session with the receiver station.
