Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single feedback processing method is used for all V2X scenarios, then the system complexity is reduced, but the feedback processing cannot satisfy diverse requirements of different scenarios
Solution Approach 1:
The patent implements dynamic feedback processing by enabling the terminal to adaptively select between different feedback modes (first feedback mode for single terminal, second feedback mode for multiple terminals) based on real-time detection of the number of feedback receiving terminals. This dynamic adaptation allows the system to handle diverse V2X scenarios without requiring separate fixed processing methods for each scenario, thereby improving versatility while managing complexity through unified adaptive logic.
2Productivity
If feedback is sent to multiple terminals simultaneously in the same time slot, then the feedback efficiency is improved, but the transmission power requirement increases
Solution Approach 1:
The patent segments the feedback transmission process into different time slots based on the number of feedback receiving terminals. When multiple terminals require feedback, the system divides the feedback transmission across multiple time slots rather than attempting simultaneous transmission. This temporal segmentation allows the terminal to maintain manageable transmission power levels while still achieving efficient feedback delivery to multiple terminals, resolving the contradiction between feedback efficiency and power consumption.
3Reliability
If feedback resources are allocated for simultaneous feedback to multiple terminals, then the feedback completeness is improved, but the resource consumption increases
Solution Approach 1:
The patent implements dynamic feedback resource allocation where the terminal detects the number of feedback receiving terminals and adapts the feedback mode accordingly. When multiple terminals are detected, the system activates the second feedback mode that utilizes consecutive feedback resources across multiple time slots. This dynamic detection and adaptation mechanism ensures complete feedback delivery to all terminals while optimizing resource consumption by only allocating additional resources when actually needed, rather than reserving resources for all possible scenarios.

AI summary
Provided are a method for data feedback processing and a device. The method is applied to a first terminal and includes: determining a plurality of second terminals as feedback receiving terminals, upon determining that feedback is required to be provided in a first time slot for first data sent by the plurality of second terminals; determining whether the first terminal supports simultaneous feedback; and determining, according to a service priority level upon determining that the first terminal does not support simultaneous feedback, a target terminal having the highest service priority level from the plurality of feedback receiving terminals, and sending, in the first time slot, feedback information to the target terminal having the highest service priority level.
