Achievable Sum-Rate Analysis of Practical Multiuser Scheduling Schemes with Limited Feedback

— We study the performance of fair physical layer schedulers that select a pair of orthogonal users for simultaneous transmission. The schemes rely on partial channel state information compatible with 3GPP specifications and differ with respect to their usage of channel quality indicator in scheduling decisions. Closed–form expressions for the achievable sum–rate of three practical scheduling algorithms are derived.
