A study on management of multi-RAT unit in mobile hotspot network enhancement system

This paper proposes a radio resource management scheme for the multi-RAT (Multiple Radio Access Technology) unit based MHN-E (Mobile Hotspot Network Enhancement) network that provides a millimeter-wave (mmWave) backhaul link of high-speed railway communications. We designed when multi-RAT unit configuration procedure is triggered and how it works, also explained detailed multi-RAT unit bearer configuration procedure when the quality of service for mTE (MHN-E Terminal Equipment) configured depends on different radio access system.
