Abstract:
A method for efficiently performing ranging in a wireless communication network may be implemented by a mobile station. The method may include sending a ranging code to a base station. The method may also include receiving a ranging response message from the base station. The method may also include determining whether a ranging failure condition is satisfied. The ranging failure condition may relate to something other than a duration of time. The method may further include re-sending the ranging code to the base station if the ranging failure condition is satisfied.
