Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple independent links are used for wireless communication, then communication reliability and performance are improved, but device complexity and difficulty of managing multiple links increase
Solution Approach 1:
The patent segments the management of multiple wireless links by introducing independent event triggers for each link. Each link (first link and second link) has its own measurement information and event trigger generation, allowing independent monitoring and control. This segmentation reduces the complexity of managing multiple links by treating them as separate, manageable units rather than a monolithic system.
Solution Approach 2:
The patent implements dynamic event triggers that are generated based on real-time measurement information from each link. The event triggers allow the system to dynamically adjust uplink and downlink allocations, power control, and channel state feedback on a per-link basis. This dynamic approach enables the system to adapt to changing channel conditions while maintaining manageable complexity through structured event-driven control.
2Productivity
If independent event triggers are generated for each link based on measurement information, then resource allocation efficiency and power control are improved, but measurement and processing complexity increase
Solution Approach 1:
The patent obtains measurement information for each link before generating event triggers. This preliminary measurement phase allows the system to prepare channel quality assessments, signal strength measurements, and other relevant data in advance. By performing measurements beforehand, the system can make faster, more efficient resource allocation decisions when event triggers are generated, improving overall productivity while managing processing complexity through structured measurement procedures.
Solution Approach 2:
The patent implements feedback mechanisms where measurement information from each link feeds into event trigger generation. The event triggers then drive adjustments in uplink/downlink allocations, power control, and channel state feedback. This closed-loop feedback system optimizes resource allocation efficiency by continuously monitoring link conditions and making data-driven decisions, while the structured feedback process helps manage measurement and processing complexity through standardized procedures.
3Productivity
If dynamic control of uplink and downlink allocations is implemented across multiple links, then network efficiency is improved, but control information transmission complexity increases
Solution Approach 1:
The patent segments control information transmission by associating separate event triggers with each link. Each event trigger independently controls uplink and downlink allocations for its specific link, rather than managing all links through a single centralized control mechanism. This segmentation reduces control information transmission complexity by localizing control decisions to individual links while maintaining overall network efficiency through coordinated multi-link operation.

AI summary
Various aspects of the disclosure relate to event triggers for independent links. For example, an event trigger may be based on measurements from multiple links. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, an event trigger may be based on aggregated measurements from multiple links.
