[Beijing, China, December five, 2018] Huawei nowadays claimed it is the initially company to complete a 5G SA functional and functionality examination of 5G LampSite. The SA tests took place in the third-section of China 5G technological know-how R&D assessments organized by the IMT-2020 (5G) Promotion Group. The benefits demonstrated a peak downlink fee of over one.eight Gbit/s on the C band with a bandwidth of one hundred MHz, close to the theoretical peak fee. This is the initially time in the field that indoor coverage assessments have been performed for 5G SA primarily based on the most detailed 3GPP Launch 15 requirements.
The IMT-2020 (5G) Promotion Group released indoor coverage as a component of its section three R&D assessments. In its new releases of Technical Technical specs of 5G Digital Indoor Process and Take a look at Scenarios of 5G Digital Indoor Process, this group defines a sequence of technological requirements for 5G indoor coverage digitalization in terms of functionality, functions, and networking.
Huawei 5G LampSite was used to sort a electronic indoor process (DIS) for the SA tests. The DIS architecture incorporates three layers: BBU, RHUB, and pRRU. The whole process supports CPRI interface and E2E fiber-optic transmission. The pRRU is a electronic headend that options a large integration of RRU and antennas. The DIS architecture satisfies the demands proposed by the IMT-2020 (5G) Promotion Group in terms of electronic headend, IT cable, and visualized O&M. So far, DIS has been widely hailed in the field as the go-to network architecture of 5G indoor coverage.
Conducted in laboratories at China Academy of Telecommunication Research and in area environments in Beijing, this spherical of assessments properly performed adequate verification of important indoor features of 5G RANs, together with uplink and downlink peak fees, downlink 4T4R, and uplink and downlink 256QAM as effectively as multi-consumer functionality. With a one hundred MHz huge C-band spectrum, a downlink solitary-consumer peak fee of extra than one.eight Gbit/s was realized on Huawei 5G LampSite, which will be set to consider indoor working experience to a new height.
Huawei has been playing an active function with the IMT-2020 (5G) Promotion Group to boost 5G R&D tests in China. In September 2018, Huawei took the guide in setting up 5G indoor coverage assessments of NSA networking. Huawei 5G LampSite has now concluded all perform and functionality assessments of 5G SA. The examination benefits are of good benefit to primary operators’ blueprint for 5G indoor coverage.
