Independent Link Event Triggers Using Aggregated Multi-Link Measurements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in effectively managing and optimizing communication across multiple independent links, particularly in coordinating channel sensing, control information transmission, power control, and event triggers, which affects the overall performance and reliability of multi-link communication.
Innovation Solution
The system employs a method to obtain and process measurement information from multiple wireless communication links to generate event triggers, enabling independent processing and management of each link, and dynamically controls uplink and downlink allocations, power control, and channel state feedback across multiple links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple independent links are used for communication, then communication reliability is improved, but coordination complexity increases
Solution Approach 1:
The patent segments the multi-link management into independent event triggers for each link. Each link generates its own event trigger based on local measurement information, allowing independent processing and management of each link while maintaining overall system reliability through diversified communication paths.
2Productivity
If joint transmission across multiple TRPs is implemented, then communication performance is improved, but system complexity increases
Solution Approach 1:
The patent divides the coordinated multi-point transmission system into independent link-level event triggers. Each TRP-link combination operates independently with its own measurement and trigger generation, simplifying the overall system architecture while maintaining the performance benefits of joint transmission across multiple TRPs.
3Adaptability or versatility
If independent event triggers are generated for each link, then link management flexibility is improved, but processing overhead increases
Solution Approach 1:
Each link autonomously generates its own event trigger based on its local measurement information without requiring centralized coordination. This self-service approach provides flexible independent link management while minimizing processing overhead by eliminating the need for complex inter-link coordination mechanisms.

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.
