Abstract
This paper considers the problem of multi-user wireless scheduling using the so-called multi-user diversity (MUDiv) concept, which requires the instantaneous channel feedback from all users to the base station. We ask ourselves whether this feedback is justified in view of the increased capacity for post scheduling. We revisit the MUDiv concept and propose a technique that allows the dramatic reduction of the feedback (by up to 90%) needs while preserving the essential of the scheme performance. The technique is analyzed both analytically and through simulations.
