Patent ID: 8750236

Claim:
A mobile subscriber device, comprising: a radio frequency front end processor; a baseband processor that exchanges signals with the radio frequency front end processor, wherein the baseband processor includes: a modulator/demodulator for modulating and demodulating transmissions; a mode selector; and a qualified downlink transmission identifier, wherein the mode selector and the qualified downlink transmission identifier are configured to: determine a predictive window; determine a first estimate of a transmission mode based on averaged channel quality measurements, which are dependent upon a size of the predictive window; calculate a margin based on reception of a qualifying downlink transmission; decrease the margin upon an inference that the qualifying downlink transmission is correctly received and a determination that a burst that is scheduled by a base station includes a higher or equal spectral efficiency than a spectral efficiency of a set of N most recently selected transmission modes, where N is a positive integer greater than 1; and select the transmission mode between the mobile subscriber device and the base station by updating the first estimate with the margin.
