A method of scheduling time division duplex frames at a base station in a time division duplex system is provided. The method includes determining if the round-trip propagation delay between the base station and a communicatively coupled subscriber station is greater than the difference between the base station turn-around time and the minimum allowed subscriber station turn-around time, and modifying time slots in a time division duplex frame being sent to the subscriber station over a communication link to extend the range of signals sent from the base station. |
