NR System Information Scheduling for Stored SIB Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In New Radio (NR) communication systems, the uncertainty in determining the validity of stored system information blocks (SIBs) due to the optional nature of system information area identity leads to test errors, increased power consumption, and complexity in terminal equipment operations.
Innovation Solution
The network device generates scheduling information based on a correlation between system information area identity and area scope, and the terminal equipment checks for consistency to validate stored SIBs, ensuring valid versions are used and reducing uncertainty and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the terminal equipment stores system information blocks (SIBs) for later use, then the acquisition process efficiency is improved, but the validity determination becomes uncertain due to the optional nature of system information area identity
Solution Approach 1:
The patent changes the parameter of system information area identity from optional to mandatory when area scope is configured. This ensures that when a terminal equipment stores SIBs with area scope, the corresponding system information area identity must also be present and consistent, eliminating uncertainty in validity determination while maintaining the efficiency benefits of stored SIBs
Solution Approach 2:
The patent introduces a validation feedback mechanism where the terminal equipment checks whether the system information area identity in scheduling information matches the stored SIB's area identity. This feedback loop ensures that only valid stored SIBs are used, resolving the reliability issue while preserving the productivity advantage of SIB storage
2Reliability
If the terminal equipment checks validity of stored SIBs by comparing system information area identity, then the reliability is improved, but the complexity of terminal equipment operations increases
Solution Approach 1:
By making system information area identity mandatory when area scope is configured, the patent simplifies the validation process. The terminal equipment only needs to check for the presence and consistency of this single parameter rather than dealing with optional fields and multiple validation rules, thus reducing operational complexity while maintaining reliability
3Reliability
If the terminal equipment re-acquires system information messages frequently to ensure validity, then the reliability is improved, but the power consumption increases
Solution Approach 1:
The patent changes the validity determination criterion by requiring system information area identity to be present when area scope is configured. This clear criterion allows the terminal equipment to accurately determine stored SIB validity without frequent re-acquisition, thereby maintaining reliability while reducing power consumption
Solution Approach 2:
The validation feedback mechanism enables the terminal equipment to determine SIB validity through simple comparison of system information area identity with stored values. This efficient validation approach eliminates the need for frequent re-acquisition operations, resolving the contradiction between reliability and power consumption
