“…This concept has been coined in 2013 and since then rapidly took off with many hands-on demonstrations across Europe, primarily in 2016. Supported by visible research initiatives, such as ADEL [3] and CORE++ [6,11,13], the LSA functionality has been tested in a number of countries with the emphasis on the feasibility of its early implementation.…”

A diversity of wireless technologies will collaborate to support the fifth-generation (5G) communication networks with their demanding applications and services. Despite decisive progress in many enabling solutions, next-generation cellular deployments may still suffer from a glaring lack of bandwidth due to inefficient utilization of radio spectrum, which calls for immediate action. To this end, several capable frameworks have recently emerged to all help the mobile network operators (MNOs) leverage the abundant frequency bands that are utilized lightly by other incumbents. Along these lines, the recent Licensed Shared Access (LSA) regulatory framework allows for controlled sharing of spectrum between an incumbent and a licensee, such as the MNO, which coexist geographically. This powerful concept has been subject to several early technology demonstrations that confirm its implementation feasibility. However, the full potential of LSA-based spectrum management can only become available if it is empowered to operate dynamically and at high space-time-frequency granularity. Complementing the prior efforts, we in this work outline the functionality that is required by the LSA system to achieve the much needed flexible operation as well as report on the results of our respective live trial that employs a full-fledged commercial-grade cellular network deployment. Our practical results become instrumental to facilitate more dynamic bandwidth sharing and thus promise to advance on the degrees of spectrum utilization in future 5G systems without compromising the service quality of their users.

“…In parallel, the European Telecommunications Standards Institute (ETSI) has been targeting to outline the LSA system architecture in their respective technical specifications (ETSI TS 103 154 and ETSI TS 103 235). In the US, a Notice of Proposed Rulemaking (NPRM) in 3.5 GHz band was introduced by the FCC [13,14].…”

“…The field measurement guidelines presented in this article can be applied to any DTT-MBB coexistence scenarios and to a wide range of spectrum sharing and cognitive radio system coexistence measurements. For example, the guidelines have been applied to study the coexistence between MBB and wireless camera links (as defined in [134]) operating in the 2.3-2.4 GHz band [88].…”

“…The spectrum data can also be used to validate the operation of the DTT and interfering signal transmissions during the measurement campaigns. Figure 11 illustrates a spectrum waterfall of signal levels recorded during a field measurement campaign to determine the protection of DVB-T wireless camera link coexisting with LTE in 2.3 GHz band in [88]. The colors in the picture represent signal levels in dBm, the -axis the frequency in MHz, and the -axis the time.…”

This article provides a survey and a general methodology for coexistence studies between digital terrestrial television (DTT) and mobile broadband (MBB) systems in the ultra high frequency (UHF) broadcasting band. The methodology includes characterization of relevant field measurement scenarios and gives a step-by-step guideline on how to obtain reliable field measurement results to be used in conjunction with link budget analyses, laboratory measurements, and simulations. A survey of potential European coexistence scenarios and regulatory status is given to determine feasible future use scenarios for the UHF television (TV) broadcasting band. The DTT reception system behavior and performance are also described as they greatly affect the amount of spectrum potentially available for MBB use and determine the relevant coexistence field measurement scenarios. Simulation methods used in determining broadcast protection criteria and in coexistence studies are briefly described to demonstrate how the information obtained from field measurements can be used to improve their accuracy. The presented field measurement guidelines can be applied to any DTT-MBB coexistence scenarios and to a wide range of spectrum sharing and cognitive radio system coexistence measurements.

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.
