Abstract
A communication system including a closed loop power control system. Prior to allowing a handoff to a new base station, the subscriber station verifies that its reverse link signal is being received by the destination base station with sufficient energy. The determination is made based on the received reverse link power control commands from the base station. Moreover, a handoff may be forced when the base station providing the best forward link signal in not receiving the reverse link signal from the subscriber station with sufficient energy.
Claims18
In a wireless communication system, a method for performing handoff comprising the steps of:
- at a first station, determining when a handoff is necessary;
- receiving a indication of link quality of signals transmitted by said first station;
- and
- selectively performing said handoff when said indication of link quality of signals transmitted by said first base station.
