NOMA-D: Date Setup for NOMA Couple in Random Access for 802.11 Networks

Non-Orthogonal Multiple Access (NOMA) is a promising technique proposed for the 5G network. This paper presents a power allocation algorithm to encourage NOMA transmission with a couple of high-power and low-power users within the 802.11 networks. The saturation throughput of our proposed NOMA-Date (NOMA-D) algorithm can be more than 20% higher than that of the legacy 802.11 system for most cases.

I. Introduction

Non-Orthogonal Multiple Access (NOMA) allows multiple data streams to be transmitted simultaneously using the same resources, e.g., the same frequency bands and/or the same time slots. It is regarded as one of the most promising candidates for boosting the overall capacity of the fifth-generation (5G) network and beyond [1], [2]. To significantly increase the performance of 802.11 networks, this paper proposes a new Medium Access Control (MAC) protocol for such networks with the power-domain NOMA.
