Abstract:
1. In an access terminal configured to operate in a wireless communication system that includes a base station, a method comprising: determining an initial forward-link data rate based on an initial signal-to-noise ratio (SNR) measurement of a forward link from the base station, the initial SNR measurement having been made by the access terminal at an initial time; subsequent to the initial time, determining an updated SNR measurement of the forward link from the base station; upon determining that the updated SNR measurement is greater than the initial SNR measurement, making a determination of a first updated forward-link data rate selected from a first tabulation of forward-link data-rate values each associated with a respective SNR threshold value of the first tabulation, and transmitting a request to the base station to receive data on the forward link at the determined first updated forward-link data rate; and upon determining that the updated SNR measurement is less than the initial SNR measurement, making a determination of a second updated forward-link data rate selected from a second tabulation of forward-link data-rate values each associated with a respective SNR threshold value of the second tabulation, and transmitting a request to the base station to receive data on the forward link at the determined second updated forward-link data rate, wherein the first and second tabulations are different.
