Abstract:
In a multi-frequency assignment communication system having at least first and second base stations allocated for respective geographic cells, with said first base station configured to transmit communication signals to subscriber terminals using at least a first frequency allocation (FA#1) and a second frequency allocation (FA#2), said second base station configured to transmit communication signals to subscriber terminals using FA#1 substantially more frequently than FA#2, said second base station having a dummy pilot at FA#2 which is used for handoff at FA#2, a method for equalizing coverage in said first base station at FA#1 and FA#2 comprising:transmitting said dummy pilot with less radio frequency (RF) power than for a pilot channel at FA#1 of said second base station, and sufficient to substantially equalize a handoff boundary between said first and second cells at both FA#1 and FA#2 in an environment of more communication traffic and associated interference at FA#1 than for FA#2.
