Patent ID: 8825101

Claim:
A method of obtaining efficient power control during soft handover in a communication network system when a user equipment is in communication with a serving radio base station and at least one non-serving radio base station over a radio interface on downlink and uplink channels, the method comprising: receiving, at the user equipment, transmit power control (TPC) commands from said serving radio base station and said at least one non-serving radio base station on said downlink channels; storing the received transmit power control commands; analyzing, at the user equipment, said stored transmit power control commands, by statistically comparing stored transmit power control commands from the serving radio base station with the stored transmit power control commands from the at least one non-serving radio base station; and when there is a discrepancy between the stored transmit power commands from the serving radio base station with the stored transmit power control commands from the at least one non-serving radio base station, adjusting a power offset on said uplink channels based on said analyzed transmit power control commands.
