Partially Blind Handovers for mmWave New Radio Aided by Sub-6 GHz LTE Signaling

摘要

For a base station that supports cellular communications in sub-6 GHz LTEbands and millimeter (mmWave) bands, we propose a supervised machine learningalgorithm to improve the success rate in the handover between the two radiotechnologies. The proposed algorithm uses sub-6 GHz LTE channel measurementsand prior mmWave measurements within a temporal window to estimate mmWavereceived signal power levels before a handover. Simulation results showimprovement in inter-radio access technology handover success rates for theproposed algorithm.
