Optimizing NR Handover by using Doppler Shift along with Legacy Power Level Algorithm

In typical wireless cellular systems, the handover mechanism involves reassigning an ongoing session handled by one cell into another. In order to support increased capacity requirement and to enable newer use cases, the next generation wireless systems will have a very dense deployment with advanced beam-forming capability. In such systems, providing a better mobility along with enhanced throughput performance requires an improved handover strategy. In this paper, we will detail a novel method for handover optimization in a 5G cellular network using Frequency error. In contrast to the conventional method, we propose to control the handovers between base-stations (BSs) using an extra parameter along with existing Power level. This agent handles the radio measurement reports from the UEs and choose appropriate handover actions in accordance with the movement prediction towards or away from a particular base station. By Measuring the frequency offset (Doppler Shift), Network can estimate the probable handover for a particular Device.
