CTOnews.com, November 4, according to the release of the 5G Promotion Group, recently, under the guidance of the IMT-2020 (5G) Promotion Group, MediaTek joined Ericsson, ZTE, Nokia Bell, CITIC Mobile and other industry partners to successfully complete the URLLC (Ultra-reliable Low-Latency Communication) and 5G LAN technology trials.

The test terminal of this technical verification uses MediaTek M80 test platform, and the URLLC test includes 5G millimeter wave band and medium and low frequency systems. Among them, M80 test terminal cooperates with 5G equipment with millimeter wave band to carry URLLC function, and successfully verifies the performance of end-to-end delay reliability up to 99.999% within 4ms. M80 test terminal cooperates with 5G equipment with short-period DS frame structure in low and middle frequency band to carry URLLC function, and verifies that the performance target of end-to-end delay reliability up to 99.99% within 10ms can be achieved in different SNR environments. CTOnews.com learned that, in addition, the time synchronization performance of 5G R16 high precision timing has also been verified in URLLC technology tests. the test results with several 5G equipment manufacturers show that using the M80 test platform which supports R16 SIB9 and high precision time output interface, the error of 5G system external timing can be less than hundreds of nanoseconds, which can meet the high precision timing requirements of vertical industry less than 1 microsecond.

The 5G LAN technology verification adopts the M80 test terminal supporting Ethernet PDU session, and completes the functional test and service test of 5G LAN based on Ethernet PDU together with a number of network devices supporting 5G LAN function, which fully verifies that the terminals supporting 5G LAN can realize point-to-point communication, multicast and broadcast communication and other service requirements. Compared with the terminals that support IP PDU, the terminals that support Ethernet PDU can be more easily integrated with layer 2 LAN and industrial Ethernet to better meet the needs of flexible construction of LAN in vertical industry application scenarios.
