Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In certain wireless communications networks, information for a system information block may not fit into a message as desired, leading to issues with size constraints.
Innovation Solution
Methods and apparatuses for segmenting or extending system information blocks to fit within message size limitations, including segmenting a first system information block into multiple segments or increasing the block size to an extended block size when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If system information block size is increased to include more information, then information completeness is improved, but message size constraint is violated
Solution Approach 1:
The patent divides a large system information block into multiple segments (first segment and second segment) that can be transmitted separately. The first segment is included in the current message while the second segment is transmitted in a subsequent message, thereby resolving the contradiction between information completeness and message size constraints.
Solution Approach 2:
The patent extends the transmission dimension by using multiple messages across different time instances. Instead of fitting all information into a single message, the system information is distributed across multiple messages, adding a temporal dimension to the transmission process and effectively bypassing the single-message size limit.
2Length of moving object
If system information is segmented into multiple messages, then message size constraint is satisfied, but transmission latency increases
Solution Approach 1:
The patent transmits the first segment of the system information block in the current message, performing preliminary transmission of the most critical information. This allows receiving devices to start processing immediately while the remaining segments are transmitted in subsequent messages, reducing the effective latency for critical information.
Solution Approach 2:
The patent implements dynamic segmentation where the system information block is divided into segments based on message size constraints. The transmission is adapted dynamically by sending different segments in different messages, allowing the system to optimize between message size compliance and transmission efficiency based on current conditions.
3Length of moving object
If system information block is segmented, then message size constraint is met, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the system information block into distinct segments with clear boundaries. Each segment is independently transmitted in separate messages, simplifying the transmission process by breaking down a complex large-block transmission into manageable smaller units that are easier to handle and transmit.
Solution Approach 2:
The patent changes the parameter of block size by introducing extended block sizes. Instead of segmenting complex information structures, the system can simply increase the block size parameter to accommodate more information in a single message when possible, reducing segmentation complexity while still meeting message size constraints through parameter adjustment.

AI summary
Apparatuses, methods, and systems are disclosed for system information block sizing. One method includes determining whether a first size of a first SIB is greater than a remaining size in a SI message. The system information message includes a second SIB having a second size. The method includes, in response to the first size of the first SIB being greater than the remaining size in the SI message, segmenting the first SIB into multiple segments including a first segment and at least one second segment. A segment size of the first segment is less than or equal to the remaining size in the SI message. The method includes including the first segment of the multiple segments of the first SIB in a third SIB. The system information message includes the second SIB and the third SIB.
