Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If HARQ processes are used during configured grant resource periods without collision handling, then wireless transmission can proceed, but transmission failures occur due to HARQ process collisions
Solution Approach 1:
The patent applies preliminary action by determining collision relationships between HARQ processes before transmission occurs. The method identifies which HARQ processes will collide in advance during the CG period, and establishes selection rules to prevent using colliding HARQ processes for MAC PDU transmission. This proactive collision detection and prevention mechanism ensures transmission reliability without sacrificing productivity.
2Productivity
If HARQ process collisions are not handled, then resource usage is simple, but transmission failures occur reducing overall efficiency
Solution Approach 1:
The patent implements preliminary determination of HARQ process collision relationships at the beginning of the configured grant period. By pre-identifying which HARQ processes will collide and establishing selection rules in advance, the system avoids transmission failures without requiring complex real-time collision detection and handling mechanisms, thus maintaining processing simplicity while improving transmission efficiency.
3Reliability
If selection rules for HARQ processes are implemented, then transmission failures are prevented, but processing complexity increases
Solution Approach 1:
The patent reduces processing complexity by determining HARQ process collision relationships and establishing selection rules in advance at the start of the CG period, rather than performing complex real-time analysis during transmission. This preliminary setup enables reliable transmission while keeping the actual transmission processing simple and efficient.
