RANGING REGIONS FOR WIRELESS COMMUNICATION RELAY STATIONS
First Claim
Patent Images
1. A relay station to be associated with a base station and a member relay station comprising:
- transmit and receive circuitry adapted to facilitate wireless communications with the base station and a mobile station; and
a control system associated with the transmit and receive circuitry and adapted to;
identify a first ranging region within an overall ranging region to use for a first ranging function, wherein the member relay station uses a second ranging region within the overall ranging region for the ranging function; and
detect a first ranging code transmitted by the mobile station via first ranging resources within the first ranging region; and
process the first ranging code to facilitate the first ranging function.

Abstract
One embodiment of the present invention provides a unique ranging technique in wireless communication environments that employ relay stations associated with a base station. Each relay station, and optionally the base station itself, can be allocated a unique ranging region having unique ranging resources that may be used by a mobile station to initiate a ranging function with the corresponding relay station or base station.
