A Technique for Licensed Spectrum Sharing between Space-Satellite and Terrestrial-Mobile Heterogeneous Multisystem
Rony Kumer Saha (KDDI Research) SAT2019-61
Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a technique for a multisystem to share the spectrum of one system to another. The multisystem incorporates an integrated satellite-mobile system and an autonomous terrestrial-mobile system (iSMS/aTMS) where the aTMS consists of numerous small cells deployed in several buildings, and the iSMS consists of a satellite station integrated with a Complementary Ground Component (CGC) station deployed along with small cells one-to-one basis within buildings. The proposed technique allows sharing the spectrum of iSMS with small cells by exploiting the high external wall penetration loss of a building. An interference management scheme to avoid the interference between CGC stations and small cells are presented. We derive capacity, spectral efficiency, and energy efficiency performance metrics for L buildings where . With extensive simulation and numerical analysis, we show the outperformance of the proposed technique over numerous existing techniques in terms of spectral efficiency and energy efficiency, satisfying the requirements for 5G systems. Finally, we list out numerous research issues to study in the future.
