On Throughput Maximization Based on Optimal Update Interval in Li-Fi Networks

Abstract:
The access point (AP) in many cases requires information about the channel condition of user equipment (UE) for better resource allocation and scheduling purposes. Although this feedback information can contribute to enhanced performance, it is at a cost of uplink throughput degradation. Limited feedback (LF) techniques offer the ways to reduce the amount of feedback at the AP. Light-Fidelity (Li-Fi) is a new high-speed and fully networked optical wireless technology where its channel is fairly static. Considering this feature, we proposed a new LF method based on the channel update interval. The optimum value for the update interval has been derived and it can provide maximum sum throughput of uplink and downlink. Results confirm that the proposed LF method can yield enhanced overall throughput compared to the traditional LF techniques.
