Claim Text:
1. A method, comprising: a wireless communication device (WCD) storing a mapping between a plurality of ranges of signal-to-noise ratios (SNRs) and a plurality of data rate indicators, wherein the mapping maps each range of SNRs with a respective data rate indicator, and wherein each data rate indicator is associated with a respective modulation-and-coding scheme (MCS) that supports a respective downlink data rate, such that higher data rate indicators are associated with MCSs that support higher downlink data rates; the WCD identifying an application on the WCD that is to receive downlink data from a radio access network (RAN); the WCD selecting a maximum data rate indicator from among the plurality of data rate indicators based on at least a type of the application on the WCD that is to receive downlink data from the RAN, wherein the type of the application indicates an extent to which the application is bandwidth-intensive; the WCD measuring a SNR of a signal transmitted by the RAN; the WCD making a determination that the mapping maps the measured SNR to a data rate indicator that is higher than the maximum data rate indicator; the WCD selecting an applicable data rate indicator, wherein the WCD selecting the applicable data rate indicator comprises the WCD selecting the maximum data rate indicator as the applicable data rate indicator based on the determination; and the WCD reporting the applicable data rate indicator to the RAN.
