Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed resource overhead configuration is used for msgA PUSCH transmission, then the configuration is simple, but the resource utilization is suboptimal in varying connection states and RA types
Solution Approach 1:
The patent applies dynamics by making the resource overhead configuration adaptive rather than fixed. The network node dynamically determines the resource overhead for msgA PUSCH transmission based on the UE's connection state (RRC_IDLE, RRC_INACTIVE, or RRC_CONNECTED) and RA type (CBRA or CFRA). This allows the system to adjust resource allocation according to actual conditions, resolving the contradiction between configuration simplicity and resource utilization efficiency.
2Productivity
If adaptive resource overhead configuration is implemented for different connection states and RA types, then resource utilization efficiency is improved, but the determination complexity increases
Solution Approach 1:
The patent applies parameter changes by modifying the resource overhead configuration parameters based on the UE's connection state and RA type. The network node determines different resource overhead values (e.g., different numbers of resource elements) for different scenarios (RRC_IDLE/CBRA, RRC_INACTIVE/CFRA, RRC_CONNECTED/CBRA, etc.). This parameter adaptation resolves the contradiction by improving resource utilization through scenario-specific optimization while managing complexity through systematic parameter selection.
Solution Approach 2:
The patent applies local quality by tailoring the resource overhead configuration to specific local conditions (connection states and RA types) rather than using a uniform configuration. Each connection state and RA type combination receives an optimized resource overhead setting appropriate to its characteristics. This local optimization improves overall resource utilization while the structured approach to determining these local parameters manages the complexity.
3Productivity
If the transport block size is determined based on scheduled resources with overhead consideration, then the transmission efficiency is improved, but the signaling overhead increases
Solution Approach 1:
The patent applies the taking out principle by extracting the resource overhead determination from the general resource allocation process and handling it separately based on connection states and RA types. The network node determines the resource overhead (number of resource elements) specifically for msgA PUSCH transmission based on the UE's state and access type, then uses this extracted information to calculate the transport block size. This separation improves transmission efficiency while managing signaling overhead through targeted information exchange.
