“…Radio spectrum is a valuable resource that delivers highvalue services for customers and citizens through communications engineering technologies. Unfortunately, the spectrum demand for innovative technology, services, and business opportunities is not synchronized with its supplies [1]. The radio spectrum is a limited resource that needs to be managed effectively to achieve its objective function, like frequency assignment based on the demand [2][3][4][5].…”

A television white space (TVWS) is an unused spectrum band in the TV broadcasting band. This unused band of frequency in TV channels can be used for different applications that benefit the people. TVWS, with its accompanying communications technologies, has promising uses and advantages in wireless systems. TVWS can replace or co-exist with other communications systems. However, gauging the technological transitions for the adoption of the TVWS system is sometimes overlooked. This paper developed a set of questions that could gauge and evaluate the level of adoption and implementation of a country's TVWS communications based on Davis's proposed technological transition architecture framework. The technological assessment developed in this paper leads to a better understanding of the niche, regime, and landscape considerations in implementing TVWS systems.

“…To solve spectrum scarcity on LTE-A band and spectrum under-utilization on some other licensed bands, it needs to deploy a cognitive LTE-A network to opportunistically use spectrum holes. For cognitive radio systems, a spectrum authorization scheme is proposed by Nokia and Qualcomm, named "Authorized Shared Access" (ASA) [1]. The ASA scheme is a spectrum management policy, which aims to enable timely availability and licensed use of harmonized spectrum for mobile devices with predictable quality of service (QoS), and to dynamically use spectrum by ASA licensees whenever and wherever unused by incumbent users using cognitive radios.…”

An Efficient Method for Managing CoMP Cooperating Set Based on Central Controller in LTE-A Systems

“Authorized Shared Access” (ASA) is a spectrum management policy which enables the secondary system to opportunistically utilize the licensed spectrum of the primary systems. In the coexistence of LTE-A system with primary systems, one of the constituent cells of the CoMP cooperating set may be affected because it has to vacate the ASA frequency for it overlaps with the protected area of the primary system. As a result, the CoMP cooperating set will be changed, and the operation of the CoMP can’t be continued execution. In this case, the UE’s QoS can’t be guaranteed and even the UE experiences call drop when using the traditional method. In this paper, by utilizing a central controller, we propose an efficient method for managing CoMP cooperating set on the ASA spectrum. The change information about the affected cell is sent to the serving cell of the CoMP through the central controller in advance. Then, the serving cell may reselect a new CoMP cooperating set or determine CoMP information indicating whether the CoMP cooperating set will be continued based on this change information, which effectively ensures continued execution of CoMP and the UE’s QoS. Simulation results show that the proposed method can provide better performance compared with the traditional method.

“…[1], show that coverage and power constraints are challenging. We propose and evaluate a different approach for authorized shared access (ASA) [2] in train networks, where data traffic of passengers on board of trains is offloaded using cabin Wi-Fi hotspots, whereby backhaul connectivity is provided through a TVWS-enabled LTE-like system. Many high-speed trains are already equipped with similar satellite-based setups [3], and no new user hardware would be required.…”

In this paper we analyze the potential use of underutilized TV frequencies to enable high-speed hotspots and data offloading in trains. We propose a system where the hotspots connect via TV frequencies to base stations that are located at the train stations. Using data from the railway network of Germany and detailed spectrum availability information we carry out a performance analysis for various realistic scenarios and configurations of a secondary system that relies on LTE technologies. Our analysis shows that sustainable data rates beyond 20 Mbps per train can be achieved in all considered scenarios, and that a proposed modified spectrum policy for authorized shared access of the secondary system will yield nearuniversal coverage. The results show that it would be possible to provide cost-efficient broadband connectivity for a national high-speed train network by using unused TV frequencies.
