1+X SSB

5G
Superior Experience

Solution Overview

SSB 1+X

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.

Scenarios and Problems

5G vertical coverage bottleneck

5G coverage scenarios and traffic distribution are complex and changeable, and vertical coverage of high-rise buildings has become a bottleneck

High O&M Costs

In the early stage of 5G, operators pay more attention to horizontal coverage. Horizontal multi-beams planning and configuration brings high O&M costs.

Vertical Horizontal Coverage Coordination

How to enhance vertical coverage and take into account the coordination of horizontal and vertical dimensions, effectively improve the utilization efficiency of 5G network resources is critical

Advantages and Highlights

Enhance Vertical Coverage

Enhances vertical coverage, improves 5G camping ratio in high-rise building scenarios

SSB Simplest Beam Design

Increases the ratio of service channels and downlink drive test data rate

Intelligent Planning and Optimization Tools

Efficiently supports the fast deployment and iterative optimization of 1+X solution

Reduce Energy Consumption

With the number of SSB reduced, 5G energy consumption is further reduced

Customer Values

Absorb more users and traffic

The vertical coverage rate of the high-rise buildings is increased by 30%, and the 5G camping rate is increased by 30%, to absorb more users and traffic

Downlink Rate Improvement

The original horizontal multi-beam SSB can be replaced by SSB 1+X in the whole network, the downlink rate can be increased by 3%-5% without changing horizontal coverage

Energy Saving

In low traffic hours, the power consumption of AAU equipment is reduced by 5%-10%, and single site power consumptionis saved by 2-3kWh daily

O&M Cost Saving

The intelligent planning and optimization tools can reduce the O&M cost by more than 30%
