A method and apparatus that configure multiple acknowledgment/negative acknowledgment (A/N) transmission delays and resources through higher layer signals, allowing terminals in wireless communication systems to receive downlink scheduling information and transmit A/Ns using specifically determined resources and delays, indicated by fields in the scheduling information, to optimize A/N transmission timing and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple A/N transmission delays and resources are configured through higher layer signals, then A/N transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments the A/N transmission configuration into multiple discrete delays and resources, allowing flexible selection through higher layer signals. This segmentation enables efficient A/N transmission by matching specific delays and resources to different downlink data transmission scenarios, thereby improving productivity while managing complexity through structured organization.
Solution Approach 2:
The patent implements dynamic configuration of A/N transmission delays and resources through higher layer signals that can be adjusted based on operational conditions. This dynamic approach allows the system to adapt A/N transmission parameters to current network conditions, improving transmission efficiency while containing complexity through programmatic control rather than hardwired configurations.
2Productivity
If A/N transmission timing is optimized through scheduling information fields, then signal transmission efficiency is improved, but measurement and detection difficulty increases
Solution Approach 1:
The patent applies local quality by incorporating specific fields within the downlink scheduling information that carry A/N transmission timing and resource indicators. These localized fields provide precise control for A/N transmission without requiring complex parsing of the entire scheduling message, thereby improving signal transmission efficiency while keeping detection and measurement manageable through targeted information extraction.
3Adaptability or versatility
If multiple A/N resources are allocated for different delays, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements multi-functionality by configuring multiple A/N resources that can be used across different transmission scenarios and delay conditions. These resources serve multiple purposes - handling different A/N transmission timing requirements, supporting various downlink data transmission configurations, and providing flexible adaptation to network conditions. This universality improves adaptability while managing complexity through standardized resource allocation patterns.
