One novel VDT+OTA test method to reproduce field radio environment in lab

This paper introduce one novel in-lab test method to reproduce a field radio channel data in lab, and use one recorded field data as an example to evaluate TDD-LTE UE performance. Firstly, it presents the field measurement method based on the scanner, and then to introduce accurate modeling way as conversion to generate in-lab playbacking file and also mapping to support CE based MPAC test solution, at last to show in-lab throughput result as KPI to fulfill end-user experience oriented 4G UE performance test.
