Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple chips are used to correspond to multiple links in MLO, then the throughput and connection stability are improved, but the device complexity increases
Solution Approach 1:
The patent divides the multi-link operation system into multiple independent chips, where each chip corresponds to a specific link. This segmentation allows each chip to independently manage its link's channel access, data transmission, and failure determination, thereby improving overall throughput while maintaining manageable complexity through modular design
Solution Approach 2:
Each chip in the system is designed with multi-functionality, capable of performing channel access, data transmission, failure determination, and retransmission management. This universal design reduces the need for separate dedicated components for each function, balancing the improvement in productivity with control over device complexity
2Reliability
If independent channel access is performed on multiple wireless links, then the connection stability is improved, but the management complexity increases
Solution Approach 1:
The management of multiple links is segmented by assigning dedicated chips to each link, with each chip independently managing its link's channel access and transmission. This segmentation simplifies management complexity by isolating control functions while maintaining connection stability through independent operation of multiple links
Solution Approach 2:
The patent implements feedback mechanisms where each chip determines whether transmission has failed and can request retransmission. This feedback loop maintains connection stability by enabling automatic recovery from transmission failures while the modular chip architecture keeps management complexity controlled through standardized failure handling procedures
3Productivity
If multi-chip controller architecture is implemented, then the flexibility and efficiency of MLO are improved, but the manufacturing cost increases
Solution Approach 1:
The multi-chip controller architecture segments the system into standardized, modular chips that can be manufactured using conventional processes. This segmentation improves efficiency through parallel processing and flexible configuration while controlling manufacturing cost by using standardized components rather than custom-designed solutions
Solution Approach 2:
The patent enables flexibility in multi-link operation by allowing dynamic assignment of data to different chips and configuration of link parameters. This parameter change capability improves efficiency and adaptability while maintaining manufacturing cost control through standardized chip designs that can be configured rather than custom-built for each scenario

AI summary
A method for multi-link operation (MLO) is provided. The method for MLO may be applied to an apparatus. The method for MLO may include the following steps. A multi-chip controller of the apparatus may assign different data to a plurality of chips of the apparatus, wherein each chip corresponds to one link of multi-links. Each chip may determine whether transmission of the assigned data has failed. A first chip of the chips may transmit the assigned data to an access point (AP) in response to the first chip determining that the transmission of the assigned data has not failed.
