ZTE, together with the Guangzhou branch of China Mobile, completed the verification of the new three-dimensional coverage platform, 5G Massive MIMO 1+X SSB (Synchronization Signal and PBCH block) platform, in the central business district of Guangzhou, China. The platform greatly optimised the coverage performance of high-rise buildings and improved the vertical coverage rate by more than 30 percent. In addition, fewer beams transmission has significantly saved resource and reduced power consumption.
To achieve high-quality 5G network coverage, ZTE introduced 5G Massive MIMO 1+X SSB platform.
ZTE and the Guangzhou branch of China Mobile fully verified the performance of 5G Massive MIMO 1+X SSB coverage platform in various scenarios, including high-rise buildings, outdoor pavement and continuous network. The result turns out that the horizontal wide beam "1" with power boosting could achieve equivalent horizontal coverage of 8 beams, while the flexible "X" vertical beams configuration increased the coverage rate of high-rise buildings by over 30 percent.
Compared with the horizontal 8-beam platform, the 1+X SSB platform with fewer beams configuration increased the access capacity by 30 percent and the service capacity by 5 percent under the high-load network condition while reducing equipment power consumption by 10 percent under the low-load network condition.
In 2020, the Guangzhou branch of China Mobile and ZTE announced to build Guangzhou into a leading 5G "pilot city". Both parties carried out a number of innovative research projects, such as the new 5G DAS (XXX) multi-channel joint transmission technology to achieve low-cost and high-efficiency 5G indoor coverage.
Moreover, the two parties will continue cooperation in various fields, including Massive MIMO complex networking, AI and big data based AAPC (Automatic Antenna Pattern Control) tool, which efficiently optimises 5G Massive MIMO multi-antenna weight, and 5G Massive MIMO 1+X SSB automatic horizontal/vertical beams optimisation.
Moving forward, ZTE and the Guangzhou branch of China Mobile will further expand the application scope of 5G Massive MIMO 1+X SSB platform in commercial 5G networks, thereby fully leveraging its values in vertical coverage performance, network capacity and equipment power consumption.
