Method for coverage optimization of multi-frequency assignment system |
摘要 |
A method for coverage optimization of a multi-frequency assignment communication system employing a dummy pilot channel, particularly a CDMA communication system. A first base station is configured to transmit communication signals to subscriber terminals using at least a first frequency allocation (FA#1) and a second frequency allocation (FA#2). A second base station transmits communication signals to subscriber terminals using FA#1 substantially more frequently than FA#2. The second base station has a dummy pilot at FA#2 which is used for handoff at FA#2. The method equalizes coverage in the first base station at FA#1 and FA#2 by transmitting the dummy pilot with less RF power than that for a pilot channel at FA#1 of the second base station, and sufficient to substantially equalize a handoff boundary between 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 at FA#2. |
