Abstract
Apparatus, and an associated method, for selecting operational parameters pursuant to which a radio communication system is operable. The operational parameters form, for instance, adaptive switching thresholds used in an adaptive modulation scheme. Separate learning controllers are configured to operate independently and cooperatively to select the adaptive switching thresholds, or other operational parameters. Iterative operation of the learning controllers causes the values to converge to optimal values.
