Title : A CQI Feedback Reduction Scheme for Multi-User MIMO/OFDMA Systems 
Authors : Myeongyun Cho, Youngju Kim, Jaekon Lee and Daesik Hong 
Conference : IEEE International Symposium on Personal, Indoor and Mobile Radio Communications 
Abstract : An opportunistic scheduling is adopted to improve the capacity of the system by exploiting the multiuser diversity of multiuser MIMO (MU-MIMO) systems. However, it requires a large amount of feedback carrying the channel quality information (CQI) of each user to the transmitter. The considered Per User Unitary and Rate Control (PU2RC) needs to feedback the preferred precoding index and its CQIs, and it has a defect in scheduling the streams for the grouped user. In order to overcome these drawbacks, a novel feedback reduction scheme is proposed and is modified for OFDMA systems in this paper. It employs transmitter controlled precoding and opportunistic feedback (TCP-OFB) in conjunction with frequency scheduling. The simulation results demonstrate that TCP-OFB/OFDMA shows comparable performance to PU2RC while it only requires far reduced feedback load.
