Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate feedback processes are configured for multiple types of transmissions (e.g., URLLC, eMBB, mMTC), then feedback reliability for each transmission type is improved, but feedback overhead and resource consumption increase significantly
Solution Approach 1:
The patent combines multiple feedback processes for different transmission types (URLLC, eMBB, mMTC) into a unified feedback mechanism. The base station and UE share a common feedback configuration that can dynamically adapt to different transmission requirements, thereby reducing the total number of separate feedback processes while maintaining reliability for each transmission type.
Solution Approach 2:
The feedback configuration is designed to be universal and multi-functional, capable of serving multiple transmission types simultaneously. The same feedback resources and processes can be dynamically allocated to different transmission types based on current network conditions and requirements, reducing overall overhead while maintaining service-specific reliability.
2Stability of the object's composition
If semi-static signaling is used to configure feedback processes, then configuration stability is improved, but adaptability to dynamic transmission requirements deteriorates
Solution Approach 1:
The patent introduces dynamic elements into the feedback configuration process. While semi-static signaling provides the base configuration framework, the system allows dynamic adjustments through downlink control information (DCI) and other dynamic signaling mechanisms, enabling the feedback configuration to adapt to changing transmission requirements while maintaining overall stability.
Solution Approach 2:
The system performs preliminary configuration through semi-static signaling to establish the feedback framework in advance, then uses dynamic signaling to make real-time adjustments. This preliminary action ensures stability while the subsequent dynamic adjustments provide the necessary adaptability to different transmission types.
3Adaptability or versatility
If dynamic signaling is used to adjust feedback configurations, then adaptability to transmission requirements is improved, but signaling overhead and processing complexity increase
Solution Approach 1:
The patent applies local quality by making dynamic adjustments only where and when needed, rather than reconfiguring the entire feedback system. The dynamic signaling targets specific parameters or specific transmission types that require adjustment, leaving the rest of the configuration unchanged, thereby reducing overall processing complexity while maintaining necessary adaptability.
4Reliability
If feedback configurations are optimized for specific transmission types (e.g., URLLC), then performance for that transmission type is improved, but resource efficiency for other transmission types deteriorates
Solution Approach 1:
The feedback configuration is made dynamic and flexible, allowing the system to optimize for specific transmission types (like URLLC) when needed while efficiently allocating resources for other transmission types at other times. The same feedback resources can be dynamically reallocated based on current traffic patterns and requirements, ensuring both high performance for specific types and overall resource efficiency.

AI summary
A user equipment (UE) may be configured to communicate a number of transmissions that may each have separate feedback processes. A feedback configuration for providing feedback for such separate feedback processes may be determined based on semistatic signaling and dynamic signaling. In some cases, semi-static signaling, such as radio resource control (RRC) signaling and dynamic signaling, such as downlink control information (DCI), may together provide a feedback configuration for a particular transmission. The semi-static signaling may provide a number of bits of feedback information, an interpretation of the bits of feedback information, or combinations thereof, and dynamic signaling may indicate that one or more of the bits are to have one of a number of available interpretations, may indicate that one or more additional bits are to be included with feedback, of combinations thereof. Feedback techniques as discussed herein may be used to provide feedback for uplink or downlink transmissions.
