“…For protecting the possible incumbents in the band, the authors in [4] have proposed a method based on an extension of the licensed shared access (LSA) for granting local access rights. Furthermore, the work in [22] verifies the technical feasibility of sharing the spectrum with incumbent users in LSA framework. All these works highlight the importance of facilitating guaranteed local access to the spectrum, by protecting the incumbent users in that band, to enable a large number local high-quality wireless networks.…”

The fifth generation (5G) networks will provide local high-quality wireless services, especially within indoor areas. New local 5G network operator models, such as the recently introduced micro-operators, are increasingly important for vertical specific service delivery. The emergence of 5G micro-operator networks in spatially confined areas depends on local spectrum availability. In this paper, we investigate the performance of local 5G indoor micro-operator networks in the 3.6 GHz and 26 GHz bands. We consider two uncoordinated TDD networks in adjacent buildings sharing the same channel with different base station antenna configurations and deployment densities. We evaluate the resulting performance of the victim network via system simulations. We have observed that the center frequency does not significantly impact the downlink performance unless the network is noise-limited. However, the uplink performance in 26 GHz band is affected by higher coupling losses between the base stations and mobile terminals. Our results indicate that beamforming and wider bandwidths help to improve the performance in 26 GHz band. More importantly, two indoor microoperators can successfully coexist with a very small separation distance in the 26 GHz band, while in the 3.6 GHz band a considerably larger isolation between the networks is required, for example in the form of a much larger separation distance.

“…The representative location gain of the 𝑛-th region, 𝐺 M (𝑛) , can be calculated using (20) as follows: Using the terrain and building information between the representative and the BS locations in each region, the diffraction loss can be determined using the Bullington model to include the effect of diffraction. Because the objective is to obtain…”

“…Spectrum sharing systems have been studied and implemented as TV white space utilization systems (e.g., IEEE 802.11af [8]- [11], IEEE 802. 15.4m [12]- [14], and IEEE 802.22 [15]- [17]), licensed shared access (LSA) in Europe [18]- [20], spectrum access system (SAS) in the United States [21]- [23], and dynamic spectrum sharing (DSS) in Japan [24]- [26]. In these spectrum-sharing systems, a primary user with a high priority (such as a system originally allocated to the spectrum) and a secondary user with a low priority (such as a system newly allocated to the spectrum) share the same spectrum.…”

This paper proposes a radio-protected area (RPA) estimation model that achieves full protection and avoids overprotection by adding an appropriate margin to the extended-Hata (EH) model, for realizing efficient spectrum sharing in the V-High-band. This additional margin, called location gain, is a location-dependent value that accounts for knife-edge losses calculated from topographic information. This study experimentally obtains the location gain by conducting VHF-band-based propagation experiments in urban and suburban areas. Subsequently, we developed an estimation formula for the location gain using topographic data, which include correction terms based on the experimental data. As a result, RPA can be estimated using only the topographic data, excluding the need for propagation experiments. The proposed model resolved the problems of the EH model (incomplete protection) and free-space (FS) model (overprotection). In urban and suburban areas, the proposed model achieved full protection and over 99.7% reduction in the RPA size of the FS model when the threshold of the received power for determining the RPA was set to -80 dBm.

“…Finally, [10] provides a brief overview of the regulatory framework concerning dynamic spectrum sharing in Europe and the US based on automated and centralized spectrum management schemes. Europe has trialed [11]- [13] the Licensed Shared Access (LSA) framework specified by ETSI Reconfigurable Radio Systems (RRS), but neither LSA nor its enhanced version eLSA have seen any adoption to date. In the US, automated spectrum access management via Spectrum Access System (SAS) has been successfully commercialized for the Citizens Broadband Radio Service (CBRS) band, which stretches between 3550-3700 MHz.…”

This paper investigates the challenges and opportunities for assigning spectrum for private 5G networks, with particular emphasis on the 3.5 GHz band and regulation issued by the Danish spectrum authority Energistyrelsen. We are chiefly interested in the dilemma between providing sufficient and clean spectrum for a private network versus ensuring that high network density can be supported. Indoor and outdoor scenarios are considered, and the performance impact of interference on different levels of service availability are investigated. We develop and propose new solutions for enhanced spectrum regulation options leveraging native 5G features, such as bandwidth part, to support denser outdoor and indoor deployments that can enhance best effort traffic and simultaneously protect spectrum for critical and delay sensitive traffic. System-level simulations show that our proposals can protect critical services and significantly increase the capacity per network in dense deployments.
