Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in relay reselection processes, particularly when remote terminal devices experience poor link quality, leading to communication failures and reduced efficiency.
Innovation Solution
Implement a relay reselection method and device that trigger reselection based on predefined conditions, such as beam and radio link failures, using radio resource control messages to manage relay changes and improve communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If relay reselection is triggered based on SD-RSRP threshold, then relay device can be selected, but communication efficiency is reduced due to frequent reselection and link quality degradation
Solution Approach 1:
The patent changes the parameter for relay reselection triggering from SD-RSRP threshold to beam failure detection. By monitoring beam failure conditions (such as beam failure counter reaching threshold) instead of relying on SD-RSRP, the system achieves more stable relay selection and reduces unnecessary reselection operations, thereby improving communication efficiency while maintaining link quality.
Solution Approach 2:
The patent implements a feedback mechanism where the relay device monitors beam failure conditions and provides feedback information to the terminal device. When beam failure is detected, the relay device sends feedback signals to trigger reselection only when necessary, avoiding frequent unnecessary reselection and improving overall communication efficiency.
2Ease of operation
If relay reselection operates without proper condition control, then reselection can be performed, but unnecessary reselection occurs leading to increased operation complexity
Solution Approach 1:
The patent enables the relay device to autonomously monitor beam failure conditions and automatically trigger reselection when necessary. The system performs self-service by detecting beam failure internally and initiating reselection procedures without requiring external intervention, simplifying the operation while managing complexity through automated condition-based triggering.
