ZTE Corporation is the first to complete the outfield test and verification of 5G millimeter wave independent network with third-party terminals.
CTOnews.com, November 1, according to the release of 5G Propulsion Group, recently, under the guidance of IMT-2020 (5G) Propulsion Group of China Institute of Information and Communications, ZTE completed the technical verification of all functional projects of 5G millimeter wave independent networking in laboratory in early October, and was the first to complete the test and verification of all performance projects under 5G millimeter wave independent networking with third-party terminals in Huairou outfield, laying the foundation for commercial use of 5G millimeter wave independent networking.
In this test, the high performance and low power consumption millimeter wave NR base station of ZTE and the CPE test terminal equipped with Qualcomm Snapdragon X655G modem are connected by FR2 only in millimeter wave independent networking (SA) mode. Under the configuration of 200MHz single carrier bandwidth, downlink 4 carrier aggregation and uplink 2 carrier aggregation, all performance items of DDDSU and DSUUU frame structures are verified respectively. It includes single user throughput, user plane and control plane delay, beam handoff and cell handoff performance. CTOnews.com learned that the test results show that the downlink peak speed exceeds 7.1Gbps when using DDDSU frame structure, and the uplink peak speed exceeds 2.1Gbps when using DSUUU frame structure.
The FR2 only mode of millimeter wave independent networking mode refers to the deployment of 5G millimeter wave network without using LTE or Sub-6GHz anchors, and the completion of terminal access and business processes. In this mode, operators can provide thousands of megabit rate and ultra-low delay wireless broadband access services for personal and business users more flexibly, and realize the deployment of green fixed wireless access networks in all applicable scenarios.
