Claim Text:
1. A method of a wireless terminal, comprising: communicating with a base station using a first carrier provided within a first coverage area of the base station; determining that the wireless terminal is in a boundary region for the first carrier that is non-overlapping with a boundary region for another carrier provided by the base station, the first carrier being subject to inter-cell interference or inter-sector interference greater than a threshold within the boundary region, and that the first carrier is a boundary carrier, the boundary carrier being a carrier provided at the boundary region that corresponds to a first overlapping area between at least two sectors within a cell of the base station or a second overlapping area between the cell of the base station and a neighboring cell of a neighbor base station, and the first overlapping area being associated with the inter-sector interference and the second overlapping area being associated with the inter-cell interference; determining at least one candidate carrier provided by the base station that is a non-boundary carrier, the at least one candidate carrier excluding the first carrier and including a second carrier provided within a second coverage area of the base station; and initiating a handoff from the first carrier to the second carrier.
