Abstract:
1. A method of uplink carrier handoff in a multiple carrier communication system, comprising: receiving a measurement report from a mobile providing information regarding path loss as measured at the mobile for one of the multiple carriers on the downlink, a serving carrier being the carrier over which the mobile communicates on the uplink; and selectively sending an instruction to the mobile to handoff to a non-serving one of the multiple carriers depending on whether a threshold requirement has been met, the threshold requirement configured to create a first coverage zone for a carrier of a first loading capacity and a second coverage zone for a carrier of a second loading capacity, the meeting of the threshold requirement being based on the received measurement report and a loading capacity of the serving carrier of the mobile, and each of the multiple carriers having an associated threshold requirement and are configured to allow a different load, the loading capacity of the serving carrier having been selected from a plurality of loading capacities.
