Abstract
An apparatus for performing a soft handoff including a power estimator, cell selector, and feedback channel generator. The power estimator receives a plurality of pilot signals that each correspond to an associated base station within an active set registry, and estimates a power level for each of the plurality of pilot signals. The cell selector is coupled to the power estimator, and is configured to select one or more base stations within the active set registry for selective blanking of a corresponding one or more of the plurality of pilot signals during a soft handoff operation. The feedback channel generator is coupled to the cell selector, and is configured to generate a cell selection feedback signal indicating the one or more base stations, where the cell selection feedback signal is subsequently transmitted to the one or more base stations, and where the cell selection feedback signal directs the one or more base stations to perform the selective blanking.
