Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If backhaul information is included in quality indicator information, then the wireless terminal station can select an appropriate connection destination, but the complexity of information processing increases
Solution Approach 1:
The quality indicator information is segmented into multiple distinct parameters including backhaul information, occupancy ratio, path loss, load, throughput, and capacitance. Each parameter is independently measured, processed, and transmitted in the beacon frame, allowing the terminal station to evaluate multiple aspects of AP performance separately and combine them for comprehensive selection decisions.
Solution Approach 2:
The access points perform preliminary processing of backhaul information and other quality indicators before transmission. The beacon frame is pre-configured with all necessary quality parameters, and the terminal station receives pre-processed information that requires minimal additional processing for connection selection, reducing real-time computational complexity.
2Adaptability or versatility
If frequency band information including quality indicator information is broadcast by beacon frame, then the multi-band WTRU can select a multi-band AP and frequency band, but the loss of time for information transmission increases
Solution Approach 1:
Multiple types of information including backhaul information, occupancy ratio, path loss, load, throughput, and capacitance parameters are merged into a single beacon frame structure. This consolidation allows the terminal station to receive comprehensive quality indicator information for multiple frequency bands and access points in one transmission, reducing the number of separate transmissions required and minimizing total information transmission time.
