Study of coexistence between 5G small-cell systems and systems of the fixed service at 39 GHz band

This paper presents simulation results in 39 GHz small cells through analysis of required frequency rejection. We calculate two types of interference amounts collected at a fixed service (FS) receiver, i.e., the aggregation of interference into an FS receiver occurred by every transmission (i) from base stations (BSs) to their associated mobile stations (MSs); (ii) from MSs and their associated BSs. The results determine how much interference rejection would be needed to protect FS operation.
