Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies face challenges in reliable beam failure recovery for multi-transmission and reception point (TRP) deployments, particularly in ensuring efficient communication and mobility across multiple TRPs, leading to potential service disruptions.
Innovation Solution
A method where a terminal device detects beam failures and transmits a beam failure recovery request to a network device, including TRP information, allowing for coordinated recovery procedures across multiple TRPs, enhancing beam management and inter-cell mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-TRP deployment is implemented to improve communication reliability, then beam failure recovery becomes more complex and difficult to manage
Solution Approach 1:
The patent segments the beam failure recovery process into distinct procedures: beam failure detection using reference signals, beam failure recovery request transmission, and beam failure recovery confirmation. Each procedure is handled independently with specific timers and reference signal sets, making the overall complex multi-TRP recovery manageable through modular processing
Solution Approach 2:
The patent introduces dynamic timer configurations (first timer and second timer) that can be adjusted based on multi-TRP deployment conditions. The system dynamically selects between different recovery procedures based on current beam status and TRP configurations, allowing flexible adaptation to changing network conditions while maintaining reliability
2Reliability
If separate beam failure detection procedures are implemented for multiple TRPs, then recovery reliability improves, but processing time and complexity increase
Solution Approach 1:
The patent configures multiple reference signal sets (first set and second set) and their corresponding timers in advance before beam failure occurs. This preliminary configuration allows the system to immediately execute the appropriate detection procedure when failure is detected, without needing to set up detection mechanisms in real-time, thus reducing detection time while maintaining separate tracking for each TRP
Solution Approach 2:
The patent creates a unified beam failure recovery framework that handles multiple TRPs through a common set of procedures and mechanisms. The same detection logic, timer management, and recovery procedures are universally applied across all TRPs, reducing overall processing complexity while maintaining reliable separate detection for each TRP
