Abstract

Unlicensed spectrum is increasingly being used by mobile operators to meet the
mobile traffic demand, and Wi-Fi is foreseen as one of the technologies for implementing mobile traffic offloading. However, Wi-Fi efficiency does not scale well as node density increases, and IEEE 802.11ax Task Group (TGax) was created in 2014 for developing WiFi technology enhancements in dense deployments. This paper investigates Wi-Fi performance in the presence of Overlapping Basic Subscriber Set (OBSS) Wi-Fi networks in indoor dense deployments. We observe that Wi-Fi could benefit from scheduled operation
with proper OBSS interference coordination. We propose a novel distributed interference coordination scheme for Wi-Fi scheduled mode operation, and evaluate it through system level simulations. Results indicate that the proposed scheme provides significant improvements over Enhanced Distributed Channel Access (EDCA) for downlink (DL) traffic.
