Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional techniques for dynamically managing beam pair links are used, then communication can be maintained, but link quality degrades due to mobility or interference leading to inefficient communication
Solution Approach 1:
The system pre-determines a set of beam pair links and their corresponding times before communication begins. This preliminary configuration allows the system to proactively prepare multiple beam options and their timing schedules, enabling quick switching when link quality degrades without requiring complex real-time calculations, thus maintaining both reliability and efficiency
Solution Approach 2:
The system dynamically switches between predetermined beam pair links based on detected link quality degradation. The beam switching is adapted in real-time by comparing actual link quality against thresholds and selecting alternative beams from the predetermined set, allowing the system to respond flexibly to mobility and interference while maintaining communication efficiency
2Reliability
If beam pair links are dynamically switched to maintain link quality, then communication reliability improves, but system complexity increases
Solution Approach 1:
The beam pair links and their corresponding times are determined in advance before communication begins. This preliminary setup creates a ready-to-use configuration that simplifies real-time beam management, as the system only needs to select from pre-configured options rather than performing complex beam calculations dynamically, thus improving reliability without significantly increasing complexity
Solution Approach 2:
The system applies different beam pair links to different time periods based on predetermined configurations. Each time period has its own optimized beam configuration, allowing the system to maintain high reliability for each specific time slot while keeping the overall management complexity manageable through localized optimization
3Adaptability or versatility
If the system cycles through multiple beam pair links at predetermined times, then adaptability to mobility improves, but loss of time occurs due to beam switching
Solution Approach 1:
The system pre-determines the set of beam pair links and their corresponding times before communication begins. This advance configuration eliminates the need for real-time beam selection and switching calculations, allowing the system to quickly adapt to mobility by simply following the predetermined schedule without incurring significant time losses
Solution Approach 2:
The system cycles through the predetermined beam pair links at specific, pre-determined times within each communication time period. This periodic switching pattern allows the system to systematically cover multiple beam options to handle mobility, while the predetermined timing minimizes decision-making delays and reduces time loss associated with dynamic beam selection

AI summary
Methods, systems, and devices for wireless communications are described. Communications by wireless devices may be modified when beam pair links (BPLs) experience decreased link quality. For example, a controlling wireless device may communicate with a secondary wireless device using a set of BPLs. The controlling and secondary wireless device may each cycle through the set of BPLs at respective times of a communication time period. Upon detecting one or more BPLs having a decreased link quality during a portion of the communication time period, the controlling wireless device may transmit a configuration modifying the communications. For instance, the modified communications may include replacing the one or more BPLs with different BPLs having a relatively higher link quality. In other cases, the modified communications may include using repeated transmissions during the portion of the communication time period or excluding the BPLs experiencing decreased link quality from the communication time period.
