Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a non-STR non-AP MLD waits for MediumSyncDelay after transmission on one link, then interference from transmission is avoided, but transmission and reception opportunities are reduced due to long waiting times
Solution Approach 1:
The AP MLD performs preliminary actions by specifying transmission_available_time information in advance in response frames. This allows the non-STR non-AP MLD to plan its transmissions ahead of time, knowing exactly when it will be available to transmit on other links, thereby reducing unnecessary waiting periods while maintaining communication quality.
Solution Approach 2:
The system dynamically adjusts transmission timing based on the transmission_available_time information exchanged between devices. Instead of using a fixed MediumSyncDelay waiting period, the non-STR non-AP MLD adapts its transmission schedule according to the dynamically provided availability information from the AP MLD, optimizing both reliability and time utilization.
2Ease of operation
If transmission time is not adjusted between links, then simple protocol operation is maintained, but transmission opportunities are lost due to fixed waiting periods
Solution Approach 1:
The AP MLD provides feedback to the non-STR non-AP MLD by including transmission_available_time information in response frames. This feedback mechanism allows the terminal to adjust its transmission timing dynamically, increasing transmission opportunities while maintaining relatively simple protocol operation through structured information exchange.
3Device complexity
If existing solutions are used without frame length information, then protocol complexity is reduced, but transmission time adjustment is impossible
Solution Approach 1:
The AP MLD performs preliminary calculation and specification of transmission_available_time based on frame length information it possesses. By doing this calculation in advance and providing the result to the terminal, the system enables precise transmission time adjustment without requiring the terminal to perform complex calculations, thus balancing complexity and capability.
