PRESS RELEASE: Minister of Industry and Information Technology, stated: “China will build 600,000 5G base stations this year. By then, the total number of 5G base stations will exceed 2.9 million.” This indicates that 5G construction in China continues to grow at a rapid pace.
At the same time, services such as new HD livestreaming and VoNR are gaining traction, making ubiquitous 5G coverage and high-quality experience essential for daily life. However, interference is a serious issue for site construction and coverage expansion. User experience is affected in the overlapping areas, especially in urban areas.
To address this issue, China Telecom Yuxi has been actively innovating and completed its first pilot for the eMIMO Pro solution in Yuxi, Yunnan. Test results demonstrate that this solution uses interference coordination to significantly reduce interference in overlapping areas. The solution has improved CEU experience by about 20% and increased the network-wide user-perceived rate by 16%, providing users with premium 5G experience.
The pilot solution, eMIMO Pro, is provided by Huawei. With its exclusive technologies such as coordinated scheduling, optimal PDCCH resource allocation, and high-precision power control, the solution not only improves transmission efficiency, but minimizes interference from neighboring cells. As such, user experience can be improved in the overlapping areas and across the entire network. This pilot deployed 10 sites in Hongta District, Jiangchuan District, and Tonghai County of Yuxi City. The average speed across the network was increased by 16.4% from 26.9 Mbps to 31.3 Mbps. (Speeds were increased from 35.2 Mbps to 40.9 Mbps in light-load scenarios, and from 21 Mbps to 24.5 Mbps in medium-load scenarios.)
A representative of China Telecom Yuxi said, “This pilot has achieved our expected result. It uses software solutions to improve network experience for users under co-channel interference. We will continue to work with Huawei to explore the latest technical solutions and provide the optimal network experience for users.”
