Mixed SSB Burst Set Configuration for 5G Signal Acquisition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, particularly in 5G NR systems, the use of different subcarrier spacings for synchronization signal blocks (SSBs) is necessary to balance faster beam sweeping and better coverage, but existing methods struggle to efficiently configure and manage these SSBs across varying frequency bands, leading to complexity in signal search and acquisition.
Innovation Solution
Configuring multiple SSB burst sets with different subcarrier spacings and parameters, including quasi-co-located transmission beams, to enable efficient signal transmission and reception, with one SSB burst set providing resource allocation information for another, allowing user equipment to identify and decode SSBs based on these configurations.

Engineering Contradiction Analysis
1Speed
If multiple SSB burst sets with different subcarrier spacings are configured, then beam sweeping speed and coverage are improved, but signal search and acquisition complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple SSB burst sets with different subcarrier spacings before actual communication occurs. The network device prepares these burst sets in advance with predetermined parameters, allowing the UE to efficiently acquire synchronization signals without performing complex real-time searches across all possible configurations.
Solution Approach 2:
The patent utilizes parameter changes by varying subcarrier spacing values across different SSB burst sets. By configuring burst sets with different numerical parameters (subcarrier spacings), the system optimizes beam sweeping performance for different frequency bands while providing structured information that reduces search complexity through predictable parameter relationships.
2Adaptability or versatility
If multiple SSB burst sets with different parameters are configured, then adaptability across frequency bands is improved, but configuration and management complexity increases
Solution Approach 1:
The patent implements universality by designing a multi-functional SSB burst set configuration system that serves multiple frequency bands and communication scenarios through a unified framework. The same configuration mechanism handles different subcarrier spacings, making the system adaptable across various frequency bands without requiring separate management procedures for each band.
Solution Approach 2:
The patent applies parameter changes by systematically varying subcarrier spacing parameters across different SSB burst sets to adapt to different frequency bands. This structured parameter variation allows the system to maintain configurability and adaptability while following predictable patterns that reduce management complexity compared to arbitrary configurations.
3Productivity
If SSBs with different subcarrier spacings are used, then data rate is improved, but resource allocation complexity increases
Solution Approach 1:
The patent applies segmentation by dividing resource allocation into distinct SSB burst sets, each with specific subcarrier spacing configurations. This segmentation allows different resource allocation strategies to be applied to different burst sets independently, simplifying the overall resource management while enabling high data rates through optimized allocations for each segment's specific characteristics.

AI summary
Aspects of the disclosure relate to configuring the structures of synchronization signal blocks (SSBs) and SSB burst sets in scenarios where two or more different types of SSB burst sets may be utilized in a wireless communication system (e.g., SSB burst sets including SSBs having different subcarrier spacing (SCS)). The SSB burst sets may be configured to include different components in an SSB (e.g., one or more of primary and second synchronization signals and a physical broadcast channel), include resource allocation information, include a physical-layer cell identity (PCID) configuration for a first SSB burst set that may be used to determine a PCID for a second SSB burst set, and enable quasi co-locating SSBs in a first SSB burst set with a second SSB burst set.
