Abstract:
1. A method for managing a list of sectors capable of communication with a subscriber station in a communication system, comprising: receiving a request to remove a sector from the subscriber station's list; determining a reverse link quality metric from the subscriber station at the sector; retaining the sector in the subscriber station's list if said determined reverse link quality metric is sufficient; and sending the retained sector a data request message on a data request channel; determining whether an imbalance exists when the sector is retained in the subscriber station's list; and transmitting from at least the sector with the highest forward link quality metric a power control command determined in accordance with the highest reverse link quality metric if the imbalance exists; wherein said determining whether an imbalance exists comprises: measuring at each sector belonging to the list reverse link quality metrics of a subscriber station; determining at each sector belonging to the list a quality metric of a forward link transmitted by the sector to the subscriber station; and declaring the imbalance if: the forward link quality metric of one of the plurality of sectors is greater than a forward link quality of the rest of the plurality sectors by a first threshold; and said measured reverse link quality metric at the one of the plurality sectors is less than said measured reverse link quality at the rest of the plurality sectors by a second threshold.
