Solution Overview
Problem
The existing wireless communication systems lack a system information sending method specific to terminal types, leading to inefficient use of resources and increased burden on terminals with varying demands for system information in diverse 6G applications.
Innovation Solution
Divide system information blocks into a first set of basic blocks and at least one second set tailored to specific terminal types, and send these blocks via a downlink channel to optimize resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the MIB+SIB method is used to broadcast system information, then system information can be transmitted to all terminals, but spectral efficiency deteriorates and terminal burden increases due to lack of differentiation for diverse terminal types
Solution Approach 1:
The patent segments system information blocks into multiple sets (first set with basic SIBs and second set with type-specific SIBs) that can be selectively transmitted to different terminal types. This segmentation allows the network to send only relevant information to each terminal type, avoiding the waste of transmitting all SIBs to all terminals, thereby improving spectral efficiency while maintaining transmission adaptability.
Solution Approach 2:
The patent introduces dynamic configuration of system information block sets based on terminal types. The network can dynamically determine which set (first or second) to transmit based on the terminal's capabilities and requirements. This dynamic approach enables flexible adaptation to different terminal types without sacrificing spectral efficiency, as the transmission content is optimized for each terminal type.
2Adaptability or versatility
If comprehensive system information is transmitted to all terminals, then all terminal types can access the system, but terminal processing burden increases
Solution Approach 1:
The patent divides system information into a first set (basic SIBs needed by all terminals) and a second set (type-specific SIBs). Terminals only need to process the first set universally and then selectively process the second set based on their type, significantly reducing processing burden compared to handling all SIBs, while maintaining compatibility across different terminal types.
Solution Approach 2:
The patent applies local quality by providing different levels of system information detail to different terminal types. Basic SIBs provide universal access information to all terminals, while type-specific SIBs provide detailed information only to terminals that require it. This localized information provision reduces overall terminal processing burden while maintaining access compatibility.
3Loss of energy
If type-specific system information blocks are transmitted, then resource efficiency improves, but system complexity increases due to multiple information sets
Solution Approach 1:
The patent segments system information into organized sets with clear definitions (first set for basic information, second set for type-specific information). This structured segmentation simplifies system information management by providing clear rules for what goes into each set and how they are transmitted, reducing the complexity burden despite the presence of multiple information sets.
