Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a wireless communication system uses multiple links to increase throughput, then data transmission speed is improved, but system complexity increases due to link management and TID mapping
Solution Approach 1:
The patent segments the wireless communication system into multiple independent links (first link, second link, etc.), each capable of handling specific traffic identifiers (TIDs). By dividing the throughput enhancement task across multiple links rather than requiring one complex high-speed link, the system achieves high productivity while managing complexity through modular link management and standardized TID-to-link mapping mechanisms
Solution Approach 2:
The patent creates a universal multi-link device that can operate across multiple wireless links simultaneously, with the capability to handle different TIDs on different links. This multi-functional device architecture allows a single system to perform multiple communication functions across various links, improving throughput while using standardized protocols for link management that prevent exponential complexity growth
2Productivity
If traffic is distributed across multiple links, then communication efficiency is improved, but link management complexity increases
Solution Approach 1:
The patent applies preliminary action by establishing TID-to-link mapping relationships in advance through beacon frames and probe response frames exchanged during the association phase. This pre-configuration of traffic routing rules allows the system to achieve efficient communication by automatically directing traffic based on pre-established mappings, rather than making complex real-time routing decisions, thus improving communication efficiency while keeping link management complexity manageable
Solution Approach 2:
The multi-link device performs self-service by autonomously determining which link to use for transmitting specific TIDs based on the TID-to-link mapping information received from beacon or probe response frames. This self-service capability allows the device to efficiently manage its own traffic distribution across links without requiring complex external coordination, improving communication efficiency while maintaining manageable link management complexity

AI summary
A non-access point (AP) multi-link device operating in a first link and a second link is disclosed. The non-AP multi-link device comprises a transmission/reception unit and a processor. The processor receives a beacon frame or a probe response frame from an AP multi-link device operating in the first link and the second link, determines a traffic identifier (TID) mapped to the first link and the second link according to TID-to-Link mapping indicated by the beacon frame or the probe response frame, and performs transmission in the first link or the second link according to the TID mapped to the first link and the second link.
