Frequency Selective Scheduling (FSS) is a prominent characteristic in 3GPP LTE systems. Frequency scheduling depends on Channel Quality Indicator(CQI) feedback report by mobile station. CQI being control information must use minimal bits maintaining the performance of system. This paper recommends a new CQI feedback method which uses existing schemes for improvement of performance of system. It throws light on enhancing throughput of Distributed Haar scheme with suitable usage of Best-M scheme. Proposed technique improves throughput while maintaining overhead reduction achieved by Haar compression schemes. Performance results indicate noticeable rise in throughput of the system as compared to Distributed Haar technique.
