With complete decoupling of horizontal and vertical broadcast beams, SSB 1+X solution achieves 3D cooperative coverage in horizontal and vertical dimensions with the simplest beam design, greatly enhancing flexible on-demand vertical coverage capability. In high-value traffic areas, SSB 1+X solution improves 5G camping ratio, absorbs more 5G users and traffic, and reduces resource occupancy due to the reduction of beams, thus increasing downlink drive test data rate. SSB 1+X is combined with symbol shutdown strategy to further save energy for base stations.
