TLDR
Several potential roles for satellite are examined including coverage extension, content distribution, providing resilience, improved spectrum utilisation and integrated signalling systems.Abstract:
The next generation of mobile radio communication systems — so called 5G — will provide some major changes to those generations to date. The ability to cope with huge increases in data traffic at reduced latencies and improved quality of user experience together with major reduction in energy usage are big challenges. In addition future systems will need to embody connections to billions of objects — the so called Internet of Things (IoT) which raise new challenges. Visions of 5G are now available from regions across the World and research is ongoing towards new standards. The consensus is a flatter architecture that adds a dense network of small cells operating in the millimetre wave bands and which are adaptable and software controlled. But what place for satellites in such a vision? The paper examines several potential roles for satellite including coverage extension, content distribution, providing resilience, improved spectrum utilisation and integrated signalling systems.read more

Joint Placement of Controllers and Gateways in SDN-Enabled 5G-Satellite Integrated Network
TL;DR: This paper first explores the satellite gateway placement problem to obtain the minimum average latency, and investigates a more challenging problem, i.e., the joint placement of controllers and gateways, for the maximum network reliability while satisfying the latency constraint.

Generalized Multicast Multibeam Precoding for Satellite Communications
TL;DR: A two-stage precoding design is proposed in order to both limit the multibeam interference and to enhance the intra-beam minimum user signal power (i.e., the one that dictates the rate allocation per beam).

Maritime Coverage Enhancement Using UAVs Coordinated With Hybrid Satellite-Terrestrial Networks
TL;DR: Simulation results demonstrate that the UAV fits well with existing satellite and terrestrial systems, using the proposed optimization framework, and is deployed for coverage enhancement of a hybrid satellite-terrestrial maritime communication network.

Physical Layer Frame in Signalling-Data Separation Architecture: Overhead and Performance Evaluation
TL;DR: This paper discusses and formulates the overhead reduction that can be achieved in next generation cellular systems as compared with the Long Term Evolution (LTE), and shows that the overhead gain does not come at the expense of performance degradation.
