According to the release of the 5G Promotion Group, recently, under the guidance of the IMT-2020 (5G) Promotion Group of the China Academy of Information and Communications Technology, after ZTE completed the technical verification of all functional projects of the 5G millimeter-wave independent networking in the laboratory in early October, the first company in Huairou The field has completed the test and verification of all performance items under the 5G millimeter-wave independent networking with third-party terminals, laying the foundation for the commercial use of the 5G millimeter-wave independent networking.

In this test, ZTE's high-performance, low-power millimeter-wave NR base station and CPE test terminal equipped with Qualcomm Snapdragon X65 5G modem are connected in FR2 only mode in millimeter-wave independent networking (SA) mode. Under the configuration of carrier bandwidth, downlink 4 carrier aggregation, and uplink 2 carrier aggregation, the verification of all performance items of DDDSU and DSUUU frame structures has been completed, including single-user throughput, user plane and control plane delay, beam switching and Cell handover performance. IT House has learned that the test results show that the peak downlink rate exceeds 7.1Gbps when the DDDSU frame structure is used, and the peak uplink rate exceeds 2.1Gbps when the DSUUU frame structure is used.

The FR2 only mode of the millimeter-wave independent networking mode refers to deploying a 5G millimeter-wave network without using LTE or Sub-6GHz anchor points, and completing terminal access and business processes. In this mode, operators can more flexibly provide multi-gigabit rate, ultra-low-latency wireless broadband access services for personal and business users, and realize green fixed wireless access network deployment in all applicable scenarios.
