COMMUNICATION SYSTEM AND METHOD OF OPERATIONS THEREFOR
First Claim
1. A method of operation in a communication system, the method comprising:
- (i) a first terminal sending to a second terminal a communication in a plurality of frames which includes a ranging region allocated for inclusion of ranging information which the second terminal uses to calculate a range between the first terminal and the second terminal; and
(ii) the second terminal sending to the first terminal a communication in a plurality of frames including a ranging information indicator to indicate to the first terminal a size and position of the ranging region;
wherein in at least one of the plurality of frames of the communication sent from the first terminal the size and position of the ranging region are known to the first and second terminals without the ranging information indicator being sent in an associated frame of the communication from the second terminal.

Abstract
A method of operation in a communication system is presented in which a first terminal sends to a second terminal a communication including ranging information by which the second terminal is able to calculate a range between the first terminal and the second terminal. The communication is sent in a plurality of frames. In at least one of the frames ranging information is included in a ranging region of the frame. The size and position of the ranging region is known to the first and second terminals without a ranging information indicator being sent in the frame to indicate the size and position of the ranging region.

10. A communication system including at least one base station and a plurality of mobile stations, wherein each of the mobile stations is operable to communicate with the base station using a method wherein the size and position of a ranging region allocated in each frame of a plurality of frames for sending of ranging information from the mobile station to the base station is constant in the plurality of frames and is the same for all of the mobile stations.
