Abstract: As the development of 5G use cases for verticals, different application has distinct requirement for 5G network. 5G systems in the same band have cross-link interference issue which makes coexistence complicated. This paper analyzed two coexistence schemes of unsynchronized operation and synchronized operation, and proposed coexistence frameworks of different 5G systems in middle band which can be used for operator 5G coexistence and spectrum efficient utilization.

Key words: middle band 5G, cross-link interference, coexistence framework
