Abstract
A high-speed data channel (105) is set to some minimum power level and changed to a second power level after at least one good frame has been received on a reverse link dedicated control channel (DCCH). The forward data channel power level (after a good reverse link frame is received on the DCCH) is increased over a plurality of frames to a power level that differs from the forward DCCH (103) power level, and is based on a difference in the number of handoff links between the DCCH (103) and the high-speed channel (105). Power control of the data channel (105) (after achieving the second power level) is then additionally based on a time between repeats sent due to negative acknowledgments of packet data frames sent on the data channel (105).
