dc.description.abstract | Opportunistic scheduling (OS) is one of key techniques
to increase the spectral efficiency in wireless packet-based systems by providing a multi-user diversity gain. However, when the OS is employed in orthogonal frequency division multiple access/frequency division duplex (OFDMA/FDD) systems, it may have implementation problems due to the need of a large amount of feedback information on the channel state information (CSI). To alleviate this implementation problem, we propose OS schemes that use partial CSI. The performance of the proposed OS schemes is verified by computer simulation. Simulation results show that the use of partial CSI can remarkably reduce the feedback signaling burden without significant performance degradation compared to the use of full CSI, making it quite practical to real applications. | en |
