The enormous proliferation of mobile and personal telecommunications data traffic has brought severe challenges to the current mobile telecommunications system. Regarding the perspectives of both users and operators, the main obstacle is the licensing cost and scarcity of available spectrum. According to recent industrial and academic works, millimetre-wave (mmW) is a potential solution for next fifth generation (5G) mobile telecommunications. 5G on Unlicensed band (5G-U) technology, is an extension of the long-term evolution (LTE) on unlicensed band (LTE-U), which opportunistically transmits LTE signals in the unlicensed spectrum, a viable solution to deal with spectrum scarcity and increased data rates. In particular, 5G-U will aggregate carriers in the mmW band, 28 GHz or 38 GHz licensed spectrum, both candidates of 5G frequency band, and 60 GHz unlicensed spectrum, namely Wireless Gigabit (WiGig). Both
systems, 5G and WiGig need to coexist without jeopardising each other. In this work, we study the coexistence of both systems in terms of downlink data rate, comparing three different scenarios: WiGig only, the coexistence of WiGig and 5G-U and 5G-U only. Results show, it is practical to operate 28 GHz licensed signal on the 60 GHz unlicensed frequency band, 5G-U can be coexisted with WiGig, and it is a good neighbourhood to current networks.
