System Information Segmentation for Large Data Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In new radio (NR) networks, the configuration information of tracking/channel state information reference signals (TRS/CSI-RS) is typically carried in system information blocks (SIBs) for transmission, posing a challenge due to the large amount of data exceeding the capacity of a single SIB.
Innovation Solution
The proposed solution involves dividing the target system information into multiple segments, which are then sent by the network device to the terminal device for reassembly. This approach allows for the transmission of system information that exceeds the capacity of a single SIB by distributing it across multiple segments carried in different SIBs or SIB-segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If system information is transmitted in a single SIB, then transmission structure is simple, but it cannot accommodate large amounts of data exceeding SIB capacity
Solution Approach 1:
The patent divides the target system information into multiple segments (first segment, second segment, etc.) and transmits them through different SIBs or SIB-segments. This segmentation allows the system to overcome the capacity limitation of a single SIB while maintaining manageable transmission structures through standardized segment handling procedures.
2Quantity of substance
If system information is divided into multiple segments, then data capacity is increased, but transmission and reassembly complexity increases
Solution Approach 1:
The patent incorporates segment indication information within each segment that pre-specifies how segments should be reassembled. This preliminary embedding of reassembly instructions simplifies the terminal device's operation, as it can automatically reconstruct the complete system information without complex external coordination or manual intervention.
3Reliability
If system information is transmitted in multiple segments, then reliability is improved through redundancy, but transmission time increases
Solution Approach 1:
The patent transmits different segments of system information in periodic transmissions through multiple SIBs or SIB-segments. This periodic transmission approach improves reliability by providing multiple opportunities for successful delivery while managing transmission time through structured scheduling, allowing terminals to receive complete information even if some transmissions are lost.
