Abstract:
1. In a wireless-communication network comprising an access terminal that is being served by a serving access node, a method comprising: the access terminal making a first determination that a forward-link packet error rate (FPER) with respect to data received by the access terminal from the serving access node is greater than an FPER threshold; the access terminal making a second determination that a last-requested forward-link data rate is not the lowest data rate among a plurality of requestable forward-link data rates; the access terminal making a third determination that a difference between a first C/I measurement and a second C/I measurement exceeds a difference threshold, wherein the second C/I measurement is greater than the first C/I measurement, and wherein the first and second C/I measurements are from among a set of C/I measurements taken by the access terminal with respect to one or more signals received from the serving access node; responsive to making the first, second, and third determinations, the access terminal identifying a carrier-to-interference-(C/I)-key value based at least in part on one or more C/I measurements from among the set of C/I measurements taken by the access terminal with respect to one or more signals received from the serving access node; the access terminal selecting, based at least in part on the identified C/I-key value, a next-requested forward-link data rate from among the one or more data rates in the plurality that are less than the last-requested forward-link data rate; and the access terminal requesting forward-link service from the serving access node at the selected next-requested forward-link data rate.
