“…Firstly, the concept was proposed by QUALCOMM [139], and developed further by CEPT, taking into account more comprehensive regulatory aspects (i.e., the level of authorisation), in order to form a more robust sharing regime, known as LSA. In LSA framework, a non-mobile wireless service provider, which could be a governmental/commercial [15], [85], [133] => Game-theory based approach => Cooperative games performs based on presharing agreements among MNOs + No need for real-time inter-MNO information sharing -Efficient and fair policies are complex to implement [87], [88], [97] incumbent, agrees to share part of its exclusive band with one or multiple MNOs, referred to as LSA licensees [48]. The framework was introduced with the aim of offering promising opportunities for the capacity and bandwidth expansion in cellular systems [137].…”

“…So, it would be unlikely for an end user to achieve the target peak data rate of 10Gb/s (of 5G systems [4]) by relying on CA and multiuser MIMO techniques alone. Other solutions, such as the deployment of millimetre Wave (mmWave) antennas are under intensive investigations in order to utilise higher frequency bands (e.g., 17- T hird Generation Partnership Project cellular communication networks, which have the potential to provide significant capacity improvements for both the Radio Access Network (RAN) the backhaul [15]. More information of mmWave can be found in [16], [17].…”

The ongoing development of mobile communication networks to support a wide range of superfast broadband services has led to massive capacity demand. This problem is expected to be a significant concern during the deployment of the 5G wireless networks. The demand for additional spectrum to accommodate mobile services supporting higher data rates and having lower latency requirements, as well as the need to provide ubiquitous connectivity with the advent of the Internet of Things (IoT) sector, is likely to considerably exceed the supply, based on the current policy of exclusive spectrum allocation to mobile cellular systems. Hence, the imminent spectrum shortage has introduced a new impetus to identify practical solutions to make the most efficient use of the scarce licensed bands in a shared manner. Recently, the concept of dynamic spectrum sharing has received considerable attention from regulatory bodies and governments globally, as it could potentially open new opportunities for mobile operators to exploit spectrum bands whenever they are underutilised by their owners, subject to service level agreements. Although various sharing paradigms have been proposed and discussed, the impact and performance gains of different schemes can be scenario-specific and vary depending on the nature of the sharing parties, the level of sharing and spectrum access scheme. In this survey, we describe the main concepts of dynamic spectrum sharing, different sharing scenarios, as well as the major challenges associated with sharing licensed bands. Finally, we conclude this survey paper with open research challenges and suggest some future research directions

Abstract-The demand for wider bandwidths has motivated the need for wireless systems to migrate to higher frequency bands. In line with this trend is an envisaged deployment of Kaband (or mmWave) cellular infrastructure. Further, to improve the spectral efficiency, developing full-duplex radio transceivers is gaining momentum. In view of this move, the paper proposes the possibility of reusing the satellite feeder uplink band in the full-duplex small cells. The motivation for such a reuse is two-fold :(a) there is virtually no interference from the small cells to the incumbent in-orbit satellite receiver, and (b) directive feeder antennas, with possibly additional isolation and processing causing negligible interference to the small cells. The presented interference analysis clearly supports the proposed coexistence.

“…1 that corresponds to the downlink band of the FSS system at 18 GHz [14]. The cellular BSs are deployed in tiers around the FSS according to the BSs intersite distance d i and the protection distance d p that represents the distance between the FSS and the first tier of BSs.…”

“…Different from [14], where we study the effect of several system parameters on the performance of coexisting FSS and cellular systems, the aim of our work is to design a cooperative scheduling algorithm where each BS schedules one user considering the achievable spectral efficiency and the impact on the FSS I/N level. We develop our framework in the FSS downlink band considering the results provided in the literature on the mmWave spectrum [15][16] and the ITU recommendations.…”

Abstract-The increasing demand for higher data rates has accelerated research on the next generation of mobile cellular networks (5G). One of the key factors of 5G is the use of a larger bandwidth allocated in the millimeter wave (mmWave) frequency spectrum. In particular, one of the candidate bands is the portion of spectrum between 17 and 30 GHz that is currently used by other technologies such as fixed satellite services (FSS) and the cellular network backhaul. In this paper, we analyze the coexistence between mobile services and FSS considering the main characteristics of the mmWave spectrum recently investigated in the literature. Moreover, we present a novel cooperative scheduling algorithm based on a game theoretic framework that exploits the use of analog beamforming at the base stations (BS). Finally, we show that adopting this algorithm ensure that the system meets the regulatory recommendation concerning the interference level at the FSS and at the same time provides a good user spectral efficiency.
