Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional scanning methods are used to acquire synchronization signal blocks across increasing bandwidths, then comprehensive cell coverage is achieved, but scanning time and acquisition latency increase significantly
Solution Approach 1:
The patent applies preliminary action by performing a first scan to identify synchronization signal blocks and extract indicated channel numbers before performing a second targeted scan. This preliminary identification allows the UE to prioritize acquisition of cell-defining SSBs in subsequent scans, reducing overall scanning time and acquisition latency while maintaining comprehensive coverage.
Solution Approach 2:
The patent segments the cell acquisition process into multiple distinct scan phases. The first scan identifies synchronization signal blocks and extracts channel number indications, while the second scan focuses on acquiring cell-defining SSBs at elevated priority levels. This segmentation allows each phase to be optimized independently, improving overall acquisition efficiency.
2Reliability
If all synchronization signal blocks are scanned with equal priority, then complete network coverage is ensured, but acquisition of critical cell-defining blocks is delayed
Solution Approach 1:
The patent applies local quality by assigning different priority levels to different synchronization signal blocks based on their characteristics. Cell-defining SSBs identified through channel number indications are scanned and acquired at elevated priority levels, while other SSBs are handled with standard priority. This differentiated approach ensures critical blocks are acquired quickly while maintaining complete network coverage.
Solution Approach 2:
The patent uses feedback from the first scan results to adjust the scanning strategy in the second scan. The channel number indications extracted during the first scan provide feedback that guides the prioritization of cell-defining SSBs in subsequent scans, creating a feedback loop that optimizes acquisition speed while ensuring reliability.
3Measurement precision
If the scanning process continuously monitors all channels, then network misconfigurations are detected, but the complexity and time consumption of the scanning process increases
Solution Approach 1:
The patent extracts channel number indications from synchronization signal blocks during the first scan. This extraction allows the system to identify and prioritize cell-defining SSBs in subsequent scans without continuously monitoring all channels with the same level of detail. The extracted channel number information is used to guide targeted acquisition, reducing scanning complexity while maintaining misconfiguration detection capability.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a synchronization signal block associated with a first channel number as part of a scan, wherein the synchronization signal block indicates a second channel number corresponding to a cell-defining synchronization signal block. The UE may attempt acquisition for the cell-defining synchronization signal block at an elevated priority level based at least in part on the synchronization signal block indicating the second channel number. Numerous other aspects are provided.
