METHOD AND APPARATUS FOR ACCESSING A WIRELESS MULTI-CARRIER COMMUNICATION SYSTEM

摘要

A subscriber station (101-103) accesses a multicarrier communication system (100) by determining (505) one or more channel characteristics that is indicative of a range of the subscriber station from a base station, selecting (510) an access code that generates an access signal having a peak to average power ratio, using the one or more channel characteristics, generating (515) an access signal from the access code, and transmitting (525) the access signal and also by determining (405) one or more channel characteristics of each frequency sub-band of a set of frequency sub-bands, selecting (410) a frequency sub-band of the set of frequency sub-bands based on the one or more channel characteristics, and transmitting (420) the access signal on the selected frequency sub-band.
