Abstract
Methods and systems are provided for using mobile-station revision ratio to improve reverse-link performance. An access node provides service to first and second subsets of access terminals, the first operating according to IS-856, Rel. 0, the second according to IS-856, Rev. A. The access node periodically transmits a reverse activity bit (RAB) to the access terminals, and also periodically computes a ratio of (a) either (1) the number of access terminals in the first subset or (2) the number of access terminals in the second subset to (b) a total number of access terminals in the first and second subsets, and transmits the ratio to at least the first subset. When the RAB is set, the access terminals in the first subset perform a ratio test by comparing the ratio with a threshold, and decrease their reverse-link data rates without reference to any reverse-link transitional probabilities when the computed ratio passes the ratio test.
