Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If simple methods like random link selection or traditional backoff mechanisms are used for traffic control in MLO mode, then the device complexity is reduced, but the data transmission efficiency and network resource utilization deteriorate
Solution Approach 1:
The patent implements dynamic link selection and aggregation limit adjustment based on real-time channel conditions. The processing circuit determines available links and calculates aggregation limits adaptively according to channel bandwidth and interference levels, allowing the system to optimize data transmission efficiency without requiring overly complex static configurations.
Solution Approach 2:
The system changes transmission parameters (aggregation limits, link selection) based on channel conditions. By adjusting the number of aggregated MPDUs according to channel bandwidth and interference characteristics of different frequency bands, the patent achieves efficient resource utilization while maintaining manageable device complexity.
2Productivity
If intelligent data flow control is implemented across multiple frequency bands, then the data transmission efficiency and resource utilization are improved, but the device complexity increases
Solution Approach 1:
The patent segments the data flow control by handling each frequency band (2.4 GHz, 5 GHz, 6 GHz) separately with band-specific aggregation limits. The processing circuit determines available links per band and applies appropriate aggregation constraints based on each band's characteristics, making the complex multi-band control manageable through structured segmentation.
Solution Approach 2:
Different aggregation limits are applied to different frequency bands according to their local characteristics. The 2.4 GHz band receives different treatment compared to 5 GHz and 6 GHz bands, with each band's aggregation limit tailored to its specific bandwidth and interference profile, optimizing overall system performance without uniform complexity.
3Quantity of substance
If aggregation limits are set based on channel bandwidth, then the network resource utilization is optimized, but the control mechanism complexity increases
Solution Approach 1:
The processing circuit pre-determines aggregation limits for each available link based on channel bandwidth before data transmission begins. By calculating and storing these limits in advance, the system optimizes resource utilization without requiring complex real-time adjustments during transmission, reducing control complexity while maintaining efficiency.

AI summary
A wireless communication device and a method for wireless communication that facilitate intelligent traffic control in a multi-link operation (MLO) mode are disclosed herein. The wireless communication device determines available communication links across different frequency bands and determines an aggregation limit for MAC Protocol Data Units (MPDUs) within a physical layer protocol data unit (PPDU) for each link. Links with smaller channel bandwidths are assigned smaller aggregation limits, and links with greater channel bandwidths are assigned larger aggregation limits. Subsequently, a link is selected, and data is transmitted to an access point through the selected link in a PPDU with a number of aggregated MPDUs that does not exceed the determined aggregation limit for that link.
