摘要：
Methods and apparatus are provided for adjusting a forward-link power-control step size. An initial active set of coverage areas for a mobile station is maintained within which a first coverage area in the initial active set has a signal strength that is stronger than that of each of the other coverage areas in the initial active set. The first coverage area is determined to have dropped from the initial active set, resulting in a modified active set. In response, a signal-strength factor is calculated based on (a) a last non-zero signal-strength measurement of the first coverage area and (b) a second value. One or more forward-link power-control step sizes is selected based on at least the calculated factor. The one or more selected step sizes is used to increase the forward-link transmission power of at least one coverage area in the modified active set.
