Solution Overview
Problem
Conventional radio switching techniques in multi-link operations for wireless devices are inefficient and complicated, leading to restricted performance due to wasted time and improper frame reception.

Engineering Contradiction Analysis
1Ease of operation
If conventional radio switching techniques are used for multi-link operations, then devices can monitor multiple links, but the switching process becomes complicated and inefficient with wasted time
Solution Approach 1:
The system performs preliminary actions by pre-configuring multiple radios to monitor different links simultaneously before frame exchanges begin. This eliminates the need for time-consuming radio switching during operations, as each radio is already positioned on its designated link ready to receive frames.
Solution Approach 2:
The system segments the link monitoring function by assigning different radios to monitor different links simultaneously. Instead of one radio sequentially switching between links, multiple radios are divided and assigned to specific links, enabling parallel monitoring without switching delays.
2Productivity
If conventional radio switching techniques are used, then devices can exchange frames on multiple links, but frame exchange errors increase due to improper frame reception
Solution Approach 1:
The system performs preliminary actions by pre-establishing dedicated radio-link mappings before frame exchanges begin. Each radio is pre-configured to monitor a specific link, ensuring that frames are received on the correct link without switching errors or timing issues that could cause reception failures.
Solution Approach 2:
The system introduces an intermediary mapping mechanism that associates each radio with specific links through configuration parameters. This intermediary layer ensures that frame exchanges occur on the correct link-radios, preventing improper frame reception and reducing frame exchange errors.
3Adaptability or versatility
If a radio switches to monitor multiple links after frame exchanges, then the device can detect events on different links, but the switching complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-configuring multiple radios to monitor different links simultaneously before operations begin. This eliminates the need for complex switching control logic, as each radio is already positioned on its designated link and can independently detect events without coordination or switching commands.
Solution Approach 2:
Each radio independently monitors its assigned link and autonomously detects events without requiring central coordination or switching control. This self-service approach simplifies the overall system complexity, as each radio component operates independently on its designated link.
