Title : A New Full-band Feedback Scheme Using the Adaptive Grouping Method in OFDMA Systems 
Authors : Woohyun Seo, Myeon-gyon Cho and Daesik Hong 
Journal : IEEE Transactions on Wireless Communications 
Abstract : Opportunistic scheduling algorithms with link adaptation can increase system throughput, but have the drawback of requiring the channel quality information (CQI) to be transmitted from all the candidate users. In order to alleviate this problem, we propose a new feedback reduction scheme that preserves CQIs over all channels. The proposed scheme binds similar CQIs in groups to represent them more effectively, and uses a simple method for fast grouping. Simulation results show that the proposed scheme with this simple grouping achieves close to perfect feedback performance with respect to the original CQIs under reasonable feedback loads.
