“…The project also observed the regulatory and technical developments to determine the most feasible spectrum utilization methods for the UHF TV broadcasting band. The potential developments in the use of the band and candidate technologies such as WiB [38] and Tower Overlay over LTE-Advanced+ (TOoL+) [39,40,41] were considered in [15].…”

This paper describes the design of a testbed for experimental validation and trialing of 5G vertical applications. The paper introduces the challenges that 5G aims to solve with regard to the spectrum demand and the convergence of different wireless communication services. The European-level 5G research program 5G Public Private Partnership (5G-PPP) is a coordinated European approach to secure European leadership in 5G. The 5G-PPP has developed a 5G Pan-European Trials Roadmap, which includes a comprehensive strategy for coordinated international preliminary and pre-commercial trials. The objective in designing Turku University of Applied Sciences (TUAS) testbed infrastructure in Turku, Finland, has been in building a testbed that can be used to contribute to the development, standardization and trialing of wireless communications in a diverse selection of scenarios and vertical applications. In addition, the paper describes the spectrum monitoring capabilities at TUAS facilities.

Despite the recent advances in broadband penetration and accessibility, broadcasting networks continue to be the most efficient way for delivering media content to large areas independently of the user density. Nevertheless, a convergence of broadcasting services into the broadband networks is foreseen. In this context, Layered Division Multiplexing (LDM) allows the joint provision of unicast, multicast, and broadcast services in mobile cells infrastructure. Despite the success of LDM in broadcasting infrastructure, its practical application in Long Term Evolution networks providing Evolved Multimedia Broadcast Multicast Services (LTE eMBMS) and 5G-MBMS is more difficult. In this paper, we experimentally quantify the cellinterference and its impact on the network performance and Quality of Service. Our experiments reveal that the inter-cell interference margin for LTE eMBMS is about 3 dB higher compared to traditional LTE networks. If a layered architecture is incorporated this higher inter-cell interference would cause a reduction of approximately 19% of the Enhanced Layer (Lower Layer) coverage.

Driven by the most advanced technologies, such as massive multiple-input multiple-output (MIMO), 3D beamforming, Software-Defined Networking, and network slicing, 5G/6G systems support radio connections and end-to-end network connectivity at ultrahigh speeds, low latency, high reliability, and massive connectivity. 5G/6G networks promise a faster, more streamlined future for broadcasters. It can handle rapid changes, along with improved quality standards in broadcasting. However, broadcasting services are becoming increasingly distributed and prevalent; thus, how to effectively provide broadcast services to end users has recently become a natural concern. In this paper, we propose a novel concept of Beamforming-as-a-Service (BFaaS) for delivering multicast and broadcast services in 5G/6G networks. We first comprehensively overview and study background standards and industrial activities through broadcast projects that have been carried over 5G platforms. Then, we shed light on the requirements of providing multicast and broadcast services to end users and the importance of beamforming in delivering multicast and broadcast services in 5G/6G networks. From this point, we define the BFaaS concept and vision and the benefits of the proposed BFaaS scheme. Next, we discuss the beam generation process, beamforming control and the channel model which is used in the proposed system model analysis. As a step further, with the proposed system model, we propose optimal algorithms for allocating beams to different service areas. The simulation results demonstrated the effectiveness of the proposed BFaaS scheme. Finally, we summarize the paper by identifying the potential areas of application of BFaaS for future research directions.INDEX TERMS 5G networks, terrestrial broadcasting, broadband, multicast and broadcast services, new radio, as-a-service, beamforming.NGUYEN HUU TRUNG received the Dipl.Eng., M.E., and Ph.D. degrees from the
