Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If downlink data is transmitted using available time-frequency resources, then resource utilization is improved, but decoding fails when SSB transmissions occupy those resources
Solution Approach 1:
The network device performs preliminary actions by determining candidate SSB transmission resources in advance and notifying the terminal device before actual data transmission. This allows the terminal to prepare rate-matching operations beforehand, ensuring both high resource utilization and reliable decoding when SSB transmissions occur.
Solution Approach 2:
The invention implements a feedback mechanism where the network device notifies the terminal device of candidate SSB transmission resources through signaling. This feedback loop enables the terminal to adjust its decoding strategy (rate-matching) based on the notified resources, resolving the conflict between resource utilization and decoding reliability.
2Reliability
If rate-matching is performed around candidate SSB resources, then decoding reliability is improved, but processing complexity increases
Solution Approach 1:
The network device provides advance notification of candidate SSB transmission resources, allowing the terminal to perform rate-matching operations in a structured manner. This preliminary information reduces processing complexity by eliminating the need for blind detection and enabling systematic rate-matching around known candidate resources.
Solution Approach 2:
The terminal device autonomously performs rate-matching operations based on the notified candidate SSB resources. By self-managing the rate-matching process using the provided information, the terminal achieves reliable decoding without requiring complex network-side intervention during actual transmission.
3Adaptability or versatility
If SSB transmission resources are not clearly identified, then resource flexibility is improved, but inter-node discovery and measurement capabilities deteriorate
Solution Approach 1:
The network device determines and notifies candidate SSB transmission resources in advance, providing clear identification without restricting overall resource flexibility. This preliminary identification enables terminals to perform accurate inter-node discovery and measurement while the network retains flexibility to allocate resources dynamically.
Solution Approach 2:
The invention introduces signaling as an intermediary mechanism that conveys candidate SSB resource information from the network to terminals. This intermediary layer resolves the contradiction by providing clear resource identification for discovery purposes while maintaining resource allocation flexibility through controlled signaling.
