1. A method for extending he cell radius between a mobile station and a base station, the method comprising the steps of:
- determining a propagation delay between the mobile station and the base station;
determining a transmit time offset for the mobile station, the transmit time offset based at least in part upon the propagation delay, wherein the step of determining a transmit time offset for the mobile station comprises the steps of transmitting a probe from the mobile station to the base station and continuing to transmit the probe from the mobile station to the base station until the mobile station receives an acknowledgement message from the base station; and
transmitting information between the mobile station and the base station at the transmit time offset.

Abstract
The present invention provides a method for extending the cell radius between a mobile station (101) and a base station (103). A propagation delay is determined between the mobile station (101) and the base station (103). A transmit time offset is determined for the mobile station (101). The transmit time offset is based at least in part upon the propagation delay. Information is then transmitted between the mobile station (101) and the base station (103) at the transmit time offset.
