Opis:: This paper has provided an overview of selected IoT architectures, relevant requirements towards 5G (and beyond) systems as well as indication of NOMA techniques suitability as a multiple access technique and recent developments in the area of radio interface for IoT coexisting with 5G (and beyond) mobile networks. The authors assume that IoT networks in the future will be augmented with NOMA-capable sink-nodes (proxy or gateway) that can deliver aggregated data from multiple sensors for delivery to the cloud or other server. The main aim of this paper is to go beyond state of the art available nowadays and indicate directions for NOMA that make it even more attractive in combination with edge computing, cloud-RAN and especially AI/ML to improve future 6G networks.

Opis:: Non-orthogonal multiple access (NOMA) has received tremendous attention for the development of 5G and beyond wireless networks. Power-domain NOMA works on the concept of assigning varying power levels to users within the same frequency and time block. In this paper we propose a novel power allocation approach that uses the Zipf distribution law that satisfies the basic condition of a NOMA system. The Zipf PA is characterized by the simplicity and ease of implementation that allows to extend the capacity of the system to support a large number of users. The numerical results show that the system achieves high throughput and energy efficiency without any parameter optimization constraints as well as improved capacity by increasing the number of users compared to the NOMA system with existing power allocation techniques.

Opis:: Non-Orthogonal Multiple Access (NOMA) with Successive Interference Cancellation (SIC) is one of the promising techniques proposed for 5G systems. It allows multiple users with different channel coefficients to share the same (time/frequency) resources by allocating several levels of (power/code) to them. In this article, a design of a cooperative scheme for the uplink NOMA Wi-Fi transmission (according to IEEE 802.11 standards) is investigated. Various channel models are exploited to examine the system throughput. Convolutional coding in conformance to IEEE 802.11a/g is applied to evaluate the system performance. The simulation results have been addressed to give a clear picture of the performance of the investigated system.
