Opportunism in Spectrum Sharing for Beyond 5G With Sub-6 GHz: A Concept and Its Application to Duplexing
With the envisioned massive connectivity era, one of the challenges for 5G/Beyond 5G (B5G) wireless systems will be handling the unprecedented spectrum crunch.A potential solution has emerged in the form of spectrum sharing, which deviates from a monopolistic new belial model spectrum usage system.This paper investigates the medium access control (
