Abstract: The process determines the I channel and Q channel components for each received soft value. The location of each soft value with respect to the fade line is determined using the I and Q channel components. These locations are averaged over a power control group duration to determine the noise density. The symbol energy is determined by subtracting the average perpendicular distance from the soft value point to the fade line from half the square of the average of the distance from the soft value point to the origin.

Abstract: The base station controller monitors the reverse link frame error rate of all the base stations involved in a soft hand-off with a radiotelephone. The average reverse link frame error rates of these base stations are then computed and the lowest of the average error rates is found. The last known transmit power of the base station having the lowest average error rate is determined. The transmit power of those base stations having a higher average reverse link frame error rate than the best base station are adjusted to the last known transmit power of the best base station.
