Synchronization Signal Block Indication for Multi-Pattern Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current synchronization signal block (SSB) determination and indication schemes in New Radio (NR) mobile communications cannot support multiple patterns, leading to difficulties in deriving slot and symbol information for user equipment (UE) during synchronization detection.
Innovation Solution
A method is introduced where the base station determines a target pattern from multiple patterns, acquires serial number information, and transmits position indication information to the UE, allowing the UE to correctly identify the pattern and position of the SSB, using existing bits in the system without additional overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the base station transmits only current period SSB serial number information, then the indication signaling is simple, but multiple patterns cannot be supported and UE cannot derive slot and symbol information
Solution Approach 1:
The indication signaling is designed to serve multiple functions: it not only indicates the SSB serial number in the current period but also implicitly conveys pattern information and time domain position information. By making the indication signaling multi-functional, the system supports multiple patterns without requiring separate signaling for each function, thus resolving the contradiction between signaling simplicity and multi-pattern support capability.
Solution Approach 2:
The patent introduces an intermediary mapping relationship between the SSB serial number and the pattern information. The UE uses this mapping as an intermediary to derive both the current period SSB serial number and the pattern identifier from the same indication signaling, enabling multi-pattern support while keeping the signaling structure relatively simple.
2Adaptability or versatility
If the system supports multiple SSB patterns, then the system flexibility is improved, but the UE cannot determine the pattern and position information from existing indication signaling
Solution Approach 1:
The SSB indication is segmented into multiple information elements that can be independently decoded by the UE. The indication signaling is divided to include both the SSB serial number and pattern-specific information, allowing the UE to separately determine both the pattern type and the position within that pattern, thus preventing information loss while supporting system flexibility.
Solution Approach 2:
The patent adds an additional dimension to the indication signaling by incorporating pattern identifier information alongside the traditional SSB serial number. This dimensional expansion allows the signaling to carry both pattern selection information and position information simultaneously, enabling the UE to fully determine SSB characteristics in multi-pattern scenarios.
3Adaptability or versatility
If additional indication signaling is added to support multiple patterns, then multi-pattern support is achieved, but the signaling overhead increases
Solution Approach 1:
The patent merges the indication of SSB serial number with the indication of pattern information into a single unified signaling structure. By combining these two functions into one signaling element rather than using separate indications, the system achieves multi-pattern support capability while minimizing the increase in signaling overhead through efficient resource utilization.
Solution Approach 2:
The system dynamically changes the interpretation parameters of the indication signaling based on the detected pattern. Different patterns are associated with different parameter interpretations, allowing the same signaling bits to convey different information depending on the pattern context, thus supporting multiple patterns without proportionally increasing signaling overhead.
