Joint Slot Number Detection and Synchronization for 5G Non-signaling Test

As 5G is becoming more commercialized, quick test of terminals also becomes necessary. The non-signaling test can reduce the test time by eliminating the establishment of the synchronization channel, so the slot number detection and synchronization needs to be completed before the non-signaling test. In this paper, based on the 5G frame structure and pilot signal characteristics, we introduce two common synchronization methods and analyze their advantages and disadvantages. Furthermore, we propose a new joint method to deal with the complex conditions in practical test. The simulation results show that the proposed method can effectively improve the time efficiency and optimize the test accuracy.
