Cognitive spectrum utilization in Ka band multibeam satellite communications

Multibeam satellite networks in Ka band have been designed to accommodate the increasing traffic demands expected in the future. However, these systems are spectrum limited due to the current spectrum allocation policies. This paper investigates the potential of applying cognitive radio techniques in satellite communications (SatCom) in order to increase the spectrum opportunities for future generations of satellite networks without interfering with the operation of incumbent services. These extra spectrum opportunities can potentially amount to 2.4 GHz of bandwidth in the downlink and 2 GHz of bandwidth in the uplink for high density fixed satellite services (HDFSS)

Cognitive Spectrum Utilization in Ka Band Multibeam Satellite Communications

Multibeam satellite networks in Ka band have been designed to accommodate the increasing traffic demands of the coming years.

Cognitive radio scenarios for satellite communications: the CoRaSat project

The study of cognitive radio (CR) techniques in SatCom research activities is still in its infancy. In this context, the CoRaSat (Cognitive Radio for Satellite Communications) project aims, for the first time, at investigating, developing, and demonstrating CR techniques in SatCom systems for a more efficient utilization of spectrum. In this chapter, an overview of the scenarios analyzed in the CoRaSat project is provided. In particular, Ka-, Ku-, S-, and C-band scenarios are considered and characterized taking into account the market and business frameworks, the regulatory and standardization frameworks, and the technology framework. The methodology applied in the CoRaSat project for scenario selection is provided as well, and preliminary system architecture is defined for the selected Ka-band scenarios. Useful conclusions for further analysis are also drawn

Satellite use cases and scenarios for 5G eMBB

This chapter presents initial results available from the European Commission H2020 5G PPP Phase 2 project SaT5G (Satellite and Terrestrial Network for 5G) [1]. It specifically elaborates on the selected use cases and scenarios for satellite communications (SatCom) positioning in the 5G usage scenario of eMBB (enhanced mobile broadband), which appears the most commercially attractive for SatCom. After a short introduction to the satellite role in the 5G ecosystem and the SaT5G project, the chapter addresses the selected satellite use cases for eMBB by presenting their relevance to the key research pillars (RPs), their relevance to key 5G PPP key performance indicators (KPIs), their relevance to the 3rd Generation Partnership Project (3GPP) SA1 New Services and Markets Technology Enablers (SMARTER) use case families, their relevance to key 5G market verticals, and their market size assessment. The chapter then continues by providing a qualitative high-level description of multiple scenarios associated to each of the four selected satellite use cases for eMBB. Useful conclusions are drawn at the end of the chapter

5GCHAMPION – disruptive 5G technologies for roll‐out in 2018

Abstract The 5GCHAMPION Europe–Korea collaborative project provides the first fully‐integrated and operational 5G prototype in 2018, in conjunction with the 2018 PyeongChang Winter Olympic Games. The corresponding technological advances comprise both an evolution and optimization of existing technological solutions and disruptive new features, which substantially outpace previous generations of technology. In this article, we focus on a subset of three disruptive technological solutions developed and experimented on by 5GCHAMPION during the 2018 PyeongChang Olympic Games: high speed communications, direct satellite‐user equipment communications, and post‐sale evolution of wireless equipment through software reconfiguration. Evaluating effectiveness and performing trials for these key 5G features permit us to learn about the actual maturity of 5G technology prototyping and the potential of new 5G services for vertical markets and end user enhanced experience two years before the launch of large‐scale 5G services

5G champion:rolling out 5G in 2018

Abstract The 5G CHAMPION Consortium will provide the first fully integrated and operational 5G prototype in 2018 — this effort is a major leap ahead compared to existing punctual technology trials, such as, e.g., Proof-of-Concept platforms focusing on mmWave communication in specific bands, etc. This paper describes the overall set-up including a synergetic combination of technologies such as beamforming based mmWave & Satellite service provisioning, virtualized infrastructure, software reconfiguration across the entire stack, accurate positioning and high-speed solutions. The key enablers are described in detail and related efforts in standards and regulation organizations are discussed
