Non-Orthogonal Multiple Access

Non-Orthogonal Multiple Access (NOMA) NOMA is a multiple access technique that has attracted a lot of interest from researchers and is considered a strong candidate for handling many of the requirements of 5G and beyond networks. Multiple access techniques allow multiple users to share the allotted resources in an effective manner. Recent studies categorize these techniques as Orthogonal Multiple Access (OMA) and Non-Orthogonal Multiple Access (NOMA). In OMA, each user can exploit […]

Minimizing Latency and Optimizing User Selection for 5G and Beyond Networks

Minimizing Latency and Optimizing User Selection for 5G and Beyond Networks The post below, is an oversimplification of the subject for the benefit of non-technical readers and the general public. Introduction The number of devices with mobile access, emerging with the development of the Internet of Things (IoT), is constantly increasing. At the beginning, the mobile phone was the only type of device that could access and utilise telecommunication networks. […]

Game theory in wireless networks

Game theoretic approaches in wireless networks One of the fundamental questions for 5G network architectures is whether the number of base stations (BSs) will be increased (Ultra-Dense Network) or will the current BSs be enhanced with an increased number of antennas and higher processing capabilities (massive MIMO). In most studies, both of these features are investigated together. Either way, the number of antennas will be significantly increased, hence several challenges […]
