Engineering Contradiction Analysis
1Quantity of substance
If the bandwidth for sending system information is limited to minimum bandwidth, then resource constraints are reduced, but transmission efficiency and flexibility deteriorate
Solution Approach 1:
The patent applies dynamics by making the resource allocation for system information transmission flexible and adjustable. The network device can dynamically determine resources for sending system information based on terminal device capabilities, and expand resources when needed. This transforms the static minimum bandwidth constraint into a dynamic resource allocation mechanism that adapts to different transmission requirements, resolving the contradiction between resource constraints and transmission efficiency.
Solution Approach 2:
The patent changes the bandwidth parameter from a fixed minimum value to an expandable range. The network device determines initial resources based on minimum bandwidth requirements, then expands these resources when additional system information needs to be transmitted. This parameter change enables the system to operate efficiently across varying bandwidth conditions while maintaining compatibility with terminal devices having different capabilities.
2Device complexity
If the bandwidth for sending system information is limited to minimum bandwidth, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The patent segments system information transmission into multiple parts that can be allocated to different resources. The network device divides system information into portions that fit within minimum bandwidth resources, then uses additional expanded resources for remaining information. This segmentation allows the system to maintain simple initial resource allocation while adapting to diverse transmission needs through structured division of information blocks.
Solution Approach 2:
The patent creates a universal resource allocation mechanism that works across different terminal device types and capability levels. The same framework of determining initial resources and expanding when needed applies whether transmitting to minimum bandwidth terminals or higher capability devices. This multi-functional approach enhances adaptability without proportionally increasing device complexity, as the expansion logic follows standardized procedures.
3Device complexity
If system information is transmitted only on current resources, then resource usage is simplified, but information completeness deteriorates
Solution Approach 1:
The patent applies preliminary action by first allocating resources based on minimum bandwidth requirements before determining if expansion is needed. The network device pre-determines initial resource allocation for system information transmission, then assesses whether additional information requires resource expansion. This preliminary allocation ensures that essential information is always transmitted on guaranteed resources, while preventing information loss through conditional expansion when necessary.
Solution Approach 2:
The patent introduces an intermediary mechanism where the network device acts as a mediator between resource constraints and information completeness requirements. The network device determines whether to expand resources based on the amount of system information that needs transmission, serving as an intermediary decision point that balances resource management simplicity with information completeness. This mediation prevents both resource waste and information loss by making context-aware allocation decisions.
