NR System Information Validation Using Area Identity Consistency
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
1Reliability
If the terminal equipment checks validity of stored SIBs using optional system information area identity, then the terminal can use stored SIB versions, but uncertainty arises leading to test errors and increased power consumption
Solution Approach 1:
The patent changes the parameter from optional system information area identity to mandatory system information area identity in scheduling information. This parameter change eliminates the uncertainty in validity determination by ensuring that the area identity is always present and can be used for reliable comparison with stored SIB versions, thereby resolving the contradiction between reliability and power consumption.
2Adaptability or versatility
If the terminal equipment stores and validates SIB versions with optional area identity, then storage functionality is provided, but test complexity and overhead increase
Solution Approach 1:
The patent makes the system information area identity mandatory in scheduling information, which simplifies the validation logic by eliminating the need to handle optional fields. This parameter change reduces test complexity and overhead while maintaining the SIB version storage capability, as the validation process becomes more straightforward with always-present area identity fields.

AI summary
A communication apparatus includes: a receiver configured to receive system information Block 1 (SIB1) including scheduling information and serving cell-common (servingCellConfigCommon) which includes supplementary uplink configuration; and a transmitter configured to transmit, on supplementary uplink, a request for a system information message (SI-message), wherein the scheduling information includes: information which a system information broadcast status for system information message is set to be not broadcasted, and configuration on supplementary uplink for requesting the system information message on the supplementary uplink.
