In 2022, under the guidance of the Ministry of Industry and Information Technology, the IMT-2030 (6G) Advancement Group organized a 6G key technology concept prototype test. ZTE Corporation has actively cooperated with the 6G Promotion Group and participated in the exploration and research of 6G-related technologies: ZTE invested a lot of manpower and resources in this test, and carried out and participated in all five types of concept prototype tests, including 6G distributed autonomous network and digital twin network concept prototype, 6G algorithmic network key technology concept prototype, 6G terahertz key technology concept prototype, 6G communication-aware integration concept prototype, 6G communication-aware integration concept prototype, and 6G key technology concept prototype. key technology concept prototype, 6G intelligent super-surface technology key technology concept prototype. The results of the experimental tests are remarkable, and the relevant technical indicators reflect better functions and performance.
In the 6G distributed autonomous network and digital twin network concept prototype test, the ZTE intent network prototype was connected to the network planning scenario verification system and completed the whole process of voice and text intent acquisition, conversion and driving the planning prototype to execute the service verification; the digital twin prototype passed the access network digital twin network capacity capability, access network digital twin network similarity and access network digital twin network prediction capability test The digital twin passed the access network digital twin network capacity, access network digital twin network similarity and access network digital twin network prediction capability tests.
In the 6G arithmetic network key technology concept prototype test, the ZTE prototype completed the arithmetic network awareness and arithmetic routing function tests in the bearer network environment built on the SRv6 architecture, and achieved better objectives: in the arithmetic network awareness function test, it supported the real-time awareness of network information such as network connection, delay, flow rate and arithmetic information such as CPU occupancy and memory occupancy of the arithmetic service deployment container; in the arithmetic routing function test, it supported the real-time awareness of arithmetic information based on the arithmetic network capacity, delay, flow rate and other information. The arithmetic routine test, it supports the ability of real-time arithmetic scheduling and network path selection based on the arithmetic network balance policy.
In the 6G terahertz key technology concept prototype test, ZTE uses the electronics terahertz system prototype, supporting up to 2*2MIMO. in the case of real-time communication, support outdoor long-distance transmission, spectrum efficiency of more than 7bit / s / Hz.
In the 6G communication sensing integration key technology concept prototype test, ZTE uses millimeter wave communication sensing calculation control integrated prototype equipment, using 1 AAU, sensing transceiver using different antenna panels in the AAU for isolation, sensing at the same time communication terminal for separate reception of the transmitted signal. The distance accuracy can reach the decimeter level, which can achieve stable positioning tracking for UAVs within 1km range, and the capability is equivalent to the GPS in the device.
In the 6G Smart Supersurface Technology key technology concept prototype test, the ZTE prototype realized the base station and RIS cooperation and realized the adjustable beam control. Compared with the uninstalled RIS, the measured point position with RIS has a gain of up to 30dB.
