Spectrum sharing for 5G

Abstract

Spectrum sharing for 5G is motivated by the fact that significantly more spectrum and much wider bandwidths than what is available today will be needed in order to realize the performance targets of 5G. First, spectrum sharing scenarios, i.e. vertical sharing and horizontal sharing, are summarized for different type of spectrum. Second, a thorough review of current spectrum sharing techniques are provided including coordination protocol, GLDB, DSA and MAC-based collision avoidance. Then spectrum sharing is analyzed specific to 5G design and one general architecture to enable 5G spectrum sharing is proposed. Finally, it is concluded that spectrum sharing becomes more and more important for 5G systems as a complementary way of using spectrum.
