Rate-Optimal Multiuser Scheduling with Reduced Feedback Load and Analysis of Delay Effects

EURASIP Journal on Wireless Communications and Networking volume 2006, Article number: 036424 (2006) Cite this article

Abstract

We propose a feedback algorithm for wireless networks that always collects feedback from the user with the best channel conditions and has a significant reduction in feedback load compared to full feedback. The algorithm is based on a carrier-to-noise threshold, and closed-form expressions for the feedback load as well as the threshold value that minimizes the feedback load have been found. We analyze two delay scenarios. The first scenario is where the scheduling decision is based on outdated channel estimates, and the second scenario is where both the scheduling decision and the adaptive modulation are based on outdated channel estimates.
