Abstract
A method of uplink carrier handoff in a multiple carrier communication system may include 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 may be the carrier over which the mobile communicates on the uplink. An instruction may be selectively sent to the mobile to handoff to a non-serving one of the multiple carriers depending on whether a threshold requirement has been met. The meeting of the threshold requirement may be based on the received measurement report and the serving carrier of the mobile. Each of the multiple carriers may have an associated threshold requirement.

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.
