ABSTRACT:
A process (10) to facilitate determination of a particular data rate to use when communicating data with respect to a mobile station comprises providing (11) historical information regarding past radio frequency channel conditions, data quantity information (12) as corresponds to a current data file to be transmitted, and assessing (13) historical data transmission as correspond to the mobile station. One then selects (14) a data rate as a function of such information. In a preferred embodiment, this comprises varying a time scaling factor as a function of relative data file size, which time scaling factor serves to influence the extent to which past history serves to otherwise influence the selection of a particular data rate.
