ZTE and the Guangzhou branch of China Mobile has recently completed the verification of the new three-dimensional coverage solution, 5G Massive MIMO 1+X SSB (Synchronization Signal and PBCH block) solution, in the central business district of Guangzhou, China.
The solution has greatly optimized the coverage performance of high-rise buildings and improved the vertical coverage rate by more than 30%, claims ZTE. In addition, fewer beams transmission has significantly saved resource and reduced power consumption.
To achieve high-quality 5G network coverage, ZTE has introduced 5G Massive MIMO 1+X SSB innovative solution. “1” here refers to the wide beam with power boosting, to provide basic coverage and implement staggered transmission between adjacent cells in time domain. To adapt to various three-dimensional coverage scenarios, “X” can be configured on demand to expand vertical coverage and achieve optimal network coverage.
ZTE said that they have fully verified the performance of 5G Massive MIMO 1+X SSB coverage solution 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 has increased the coverage rate of high-rise buildings by over 30%.
