Beam Sweeping Service SSB Period Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G NR network beam sweeping procedures lead to significant SSB overhead and reduced traffic transmission efficiency due to equal treatment of all beams, despite varying traffic loads and application services.
Innovation Solution
Implementing a beam sweeping service that configures multiple SSB burst sets with different SSB periods based on context information, such as beam utilization, to prioritize heavily used beams and optimize resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If all beams are treated equally with the same SSB period, then comprehensive service coverage is achieved, but SSB overhead increases and resource efficiency decreases
Solution Approach 1:
The patent applies local quality by configuring different SSB periods for different beams based on their specific traffic load characteristics. High traffic load beams use shorter SSB periods (e.g., 5ms or 10ms) to ensure adequate coverage and synchronization, while low traffic load beams use longer SSB periods (e.g., 20ms or 40ms) to reduce overhead. This localized optimization resolves the contradiction by making each beam's SSB configuration match its actual service requirements rather than applying a uniform configuration across all beams.
Solution Approach 2:
The patent changes the SSB period parameter dynamically based on beam traffic load conditions. The network device determines traffic load for each beam and adjusts the SSB period accordingly, transforming the fixed uniform SSB period into a variable parameter that adapts to different service scenarios. This parameter change enables the system to reduce overall SSB overhead while maintaining adequate coverage for high-traffic beams.
2Area of stationary object
If SSB transmissions are increased to improve coverage, then service area coverage is enhanced, but traffic transmission efficiency is reduced
Solution Approach 1:
The patent implements local quality by applying different SSB transmission frequencies to different beams based on their traffic load. Beams serving high-traffic areas maintain frequent SSB transmissions to ensure robust coverage and synchronization, while beams in low-traffic areas reduce SSB transmission frequency. This localized differentiation resolves the contradiction by optimizing coverage where needed while preserving traffic transmission efficiency in low-traffic regions.
3Device complexity
If uniform SSB configuration is used for all beams, then system simplicity is maintained, but resource allocation efficiency deteriorates
Solution Approach 1:
The patent resolves this contradiction by implementing local quality through differentiated SSB configurations. The network device evaluates traffic load for each beam and assigns appropriate SSB periods, creating a tailored configuration for each beam's requirements. This approach increases resource allocation efficiency by matching SSB resources to actual traffic needs while maintaining manageable system complexity through automated traffic load-based decision-making.

AI summary
A method, a device, and a non-transitory storage medium are described in which a beam sweeping service is provided. The service may include generating multiple and different synchronization signal block burst sets that have different periodicities. The synchronization signal block burst sets may have different priorities based on one or multiple criteria. The one or multiple criteria may include radio beam utilization. The service may also include a multi-tier random access based on the multi-tier synchronization signal block burst sets.
