During the past 8 years, Marcin has served as R&D Engineer, Lead Researcher, R&D Consultant, Technical Trainer and Technical Leader. He has been providing expert level courses in the area of LTE/LTE-Advanced for leading mobile operators and vendors. Marcin provides consulting services to business projects in the area of 5G related topics. Marcin was a work-package leader in EU-funded research projects aiming at radio interface design for 5G including FP-7 5GNOW and FP-7 SOLDER. He co- authored a number of research papers targeting 5G radio interface design. Marcin is the co-founder of Grandmetric Ltd., responsible for mobile/wireless consulting. Michał Szydełko Consultant and Founder Movilo Ltd. Michał Szydełko received his M.S. degree in Mobile Telecommunication from the Wroclaw University of Technology in 2005. He was involved in 3GPP standardization in RAN4 as Nokia Siemens Networks delegate, taking responsibility of BS demodulation requirements for WCDMA and LTE/LTE-A. Michal was a work-package leader in EU-funded FP-7 research projects SAPHYRE, which aimed at novel spectrum and infrastructure sharing schemes for mobile networks. He (co)-authored several research papers on spectrum sharing and 5G requirements. Currently he is actively supporting the 3GPP standardization process of the Active Antennas Systems (AAS) work in Rel-13/14, as well as NR studies. Michal is the founder of Movilo Ltd., covering mobile R&D and 3GPP standardization consulting. Authors grandmetric.com

- 13. Summary • Complex multi-RAT system Unified RRM required. Native incorporation of SON - to manage network towards unified user experience across multiple converged RATs. • For efficient usage of novel spectrum licensing schemes (e.g. LSA) and network topologies (e.g. UDN) Radio resources coordination needed on multiple levels: inter-MNO, inter-band, inter-RAT, inter-layer, inter-site. • For fully dynamic spectrum access utilization High level flexibility in RF domain needed. High level of programmability relying on SDN/SDR to enable fully dynamic spectrum access. grandmetric.com
