First Claim
Patent Images
1. A system, comprising:
- a plurality of remote stations each comprising a plurality of sectors, wherein each remote station comprises;
a processor which determines sector load information; and
a transmitter which transmits the sector load information; and
a wireless communicator, served by a current serving sector, comprising;
a channel quality estimator which measures the carrier-to-interference (C/I) ratio for each sector in the wireless communicator'"'"'s Active Set (AS);
a memory which stores the carrier-to-interference (C/I) ratio measurements for the sectors in the wireless communicator'"'"'s Active Set (AS); and
a processor which determines a new serving sector based on the carrier-to-interference (C/I) ratio measurements and the sector load information for each of the AS sectors.

Abstract
Improved serving sector selection mechanisms are provided which convey sector load information to a wireless communicator. The wireless communicator can use carrier-to-interference (C/I) ratio measurements and sector load information for each of its Active Set (AS) sectors (or all sectors in its Active Set (AS)) to determine the best serving sector.
