Abstract

In this letter, we propose a low-complexity adaptive channel state information (CSI) feedback scheme to maximize the throughput in IEEE 802.11ac systems. We analyze the two factors - the interference and the feedback overhead -and develop a method to attain an optimal CSI feedback quantization level with minimal additional complexity. Our numerical results and complexity comparisons verify the efficiency of the proposed scheme in terms of throughput and complexity.
