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 meeting of the threshold requirement being based on the received measurement report and the serving carrier of the mobile, and each of the multiple carriers having an associated threshold requirement and allowing a different load.
