“…However, as a load of URLLC traffic may not be known in advance this approach may result in inefficient use of resources. A viable alternative is to utilize priorities between traffic flows as illustrated in [90], [91]. Compared to the resource reservation technique, this approach does not suffer from resource utilization problem but may lead to reduced service performance of eMBB flows.…”

Millimeter wave (mmWave) and terahertz (THz) radio access technologies (RAT) are expected to become a critical part of the future cellular ecosystem providing an abundant amount of bandwidth in areas with high traffic demands. However, extremely directional antenna radiation patterns that need to be utilized at both transmit and receive sides of a link to overcome severe path losses, dynamic blockage of propagation paths by large static and small dynamic objects, macroand micromobility of user equipment (UE) makes provisioning of reliable service over THz/mmWave RATs an extremely complex task. This challenge is further complicated by the type of applications envisioned for these systems inherently requiring guaranteed bitrates at the air interface. This tutorial aims to introduce a versatile mathematical methodology for assessing performance reliability improvement algorithms for mmWave and THz systems. Our methodology accounts for both radio interface specifics as well as service process of sessions at mmWave/THz base stations (BS) and is capable of evaluating the performance of systems with multiconnectivity operation, resource reservation mechanisms, priorities between multiple traffic types having different service requirements. The framework is logically separated into two parts: (i) parameterization part that abstracts the specifics of deployment and radio mechanisms, and (ii) queuing part, accounting for details of the service process at mmWave/THz BSs. The modular decoupled structure of the framework allows for further extensions to advanced service mechanisms in prospective mmWave/THz cellular deployments while keeping the complexity manageable and thus making it attractive for system analysts.

“…The preliminary results delivered in [11] investigate the impact of different radio configurations at the physical and media-access control layers, which provides an important conclusion that the dedicated reserved bandwidth for the eMBB and URLLC use cases in industrial applications can strongly impact the effectiveness of the services in terms of the throughput and latency. Next, the authors in [12] proposed simultaneous support of eMBB and URRLC services via an explicit prioritization method, which allows perfect isolation and stable performance characteristics for URLLCbased industrial applications even in a dynamically changing environment, while eMBB traffic with slightly weaker requirements would experience dynamic transitions in terms of application performance.…”

The future of networking will be driven by the current emerging trends of combining the physical and virtual realities in cyberspace. Considering the ambient pandemic challenges, the role of virtual and augmented reality will definitely grow over time by transforming into the paradigm of the Metaverse of Things, where each person, thing or other entity will simultaneously exist within multiple synchronized realities. In this paper, we propose a novel framework for future metaverse applications composed of multiple synchronized data flows from multiple operators through multiple wearable devices and with different quality requirements. A new service quality model is proposed based on a customizable utility function for each individual data flow. The proposed approach is based on dynamic fine-grained data flow allocation and service selection using non-fungible tokens, which can be traded over the blockchain among users and operators in a decentralized mobile network environment.
