Abstract

A method for a subscriber station to perform network entry in a multi-carrier wireless environment that has a primary carrier and at least one secondary carrier associated with a base station. The method includes sensing a carrier in an area serviced by the base station and determining if the carrier is a primary carrier or a secondary carrier. The method further includes performing the network entry if the determining establishes that the sensed carrier is a primary carrier and not a secondary carrier.

Claims

1. A method for an SS to perform network entry in a multi-carrier wireless environment that has a primary carrier and at least one secondary carrier associated with a BS, the method comprising:

a. sensing a carrier in an area serviced by the BS;

b. determining if the carrier is a primary carrier or a secondary carrier;

c. performing the network entry if the determining establishes that the sensed carrier is a primary carrier and not a secondary carrier.
