Abstract  Abstract

Embodiments of the present disclosure provide a feedback generator (106) a feedback decoder and methods of operating a feedback generator and decoder. In one embodiment the feedback generator is for use in user equipment and includes a CQI profile module (107) configured to provide a differential channel quality indicator wherein the differential channel quality indicator represents a difference between indices corresponding to allocatable channel quality indicators. The feedback generator also includes a transmit module (108) that transmits the differential channel quality indicator. In one embodiment the feedback decoder is for use in a base station and includes a receive module (121) configured to receive a differential channel quality indicator. The feedback decoder (120) also includes a CQI selection module (122) configured to provide allocatable channel quality indicators from the differential channel quality indicator based on a differential index wherein the differential index represents a difference between indices corresponding to the allocatable channel quality indicators.
