ABSTRACT:
A method for assigning subscribers between narrowbeam sectors includes, in a first embodiment, off-loading subscribers to alternate sectors when a current sector becomes loaded beyond a loading threshold. The subscriber(s) having the greatest signal quality measure (e.g., power setting) are preferably selected for off-loading, since such are typically in regions having the greatest overlap with other sectors (e.g., close to the antennas). The selected subscriber(s) are transferred to an alternate sector, preferably one having the best received signal quality with the subscriber and also having loading beneath the loading threshold.
