5G millimeter wave UE test method and analysis by Jian GONG, Yu ZHANG

“…In the 5G millimeter wave UE OTA RF conformance test, EIRP and TRP type of tests are important OTA items.Currently, this method relying on 3GPP-defined random scan to lock the beam to determine the maximum EIRP and TRP, but this method is time-consuming and lacks accuracy.A non-signaling test method was proposed, which could not only achieve more accurate measurements compared with the current EIRP and TRP test methods but also make it possible to use the non-directional OTA site as the measurement environment, further reducing the test cost and time cost, and increasing the flexibility of the test environment selection.…”

5G millimeter wave cell search algorithm with beam sweeping by Min SHEN, Jing LIANG, Jiazhi HOU

“…Due to the high carrier frequency of the 5G millimeter wave,a large initial access frequency may cause inaccurate time-frequency synchronization at the transmitting and receiving ends and incorrect detection of the physical layer cell identifier.A cell search scheme for 5G millimeter waves to send synchronization signals in a beam sweeping mode at high frequencies was analyzed and simulated.Specifically,a multi-directional synchronization signal block sent by a DFT codebook at the base station side was proposed.The terminal used an omnidirectional antenna to receive multi-beam signals and used a series of synchronization algorithms to complete time,frequency synchronization,and physical layer cell identification.Simulation results show that the proposed main synchronization signal detection algorithm with cross-correlation of pre-stored integer frequency offset and received signal has good cell search performance on 5G millimeter-wave channels.…”
