Apparatus and method for ranging in broadband wireless communication system

摘要

Provided is an apparatus and method for ranging in a broadband wireless communication system. In a method for communication of a base station, a received signal and ranging codes are correlated to detect codes. Feedback information for the detected codes is generated, and a ranging feedback message including the generated feedback information is generated. The ranging feedback message is physical-layer-encoded and the resulting data are broadcast. The base station combines and broadcasts data region allocation information and control information for ranging codes received from a plurality of mobile stations. Therefore, resources can be saved and a signalling process can be simplified.
