A system and method for processing signals in a communication system is disclosed herein. The system and method comprises processing steps and processing logic for generating a downlink subframe comprising a preamble and a plurality of data bursts within a predetermined frequency band; embedding first and second sets of downlink subframe parameters in the downlink subframe; transmitting the downlink subframe; receiving the downlink subframe; processing data in the preamble to obtain channel quality indicator (CQI) information; and using the CQI information to select either the first set or set second set of downlink subframe parameters to process the data bursts in the downlink subframe.
