1. A method for performing wireless communication with a base station, and direct transmissions to at least one second mobile station, comprising:
- at a first mobile station;
receiving first data from the base station using a downlink band of a cellular spectral resource;
transmitting second data to the base station using an uplink band of the cellular spectral resource;
receiving a message from the base station indicating resources allocated for direct transmissions between the first mobile station and the at least one second mobile station; and
based at least in part on the received message from the base station, transmitting information directly to the at least one second mobile station using the uplink band of the cellular spectral resource, wherein the first mobile station transmitting the information directly to the at least one second mobile station comprises transmitting signals similar in form to signals used in transmitting the second data to the base station.

Abstract
Systems and methods are provided for delivering both PMP communications, for example standard cellular communications via a base station, and also delivering P2P communications, for example, communications between two mobile stations, using the same spectral resources for both types of communication.
