Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no effective solution for handling radio link failure in sidelink interfaces, leading to resource wastage and inefficient data transmission in LTE systems.
Innovation Solution
A method and apparatus for detecting and reporting radio link failure between terminals, including an identifier, indication, or cause of failure, and releasing corresponding resources to a serving base station, enabling timely resource reclamation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If no solution is provided for handling radio link failure in sidelink interface, then device complexity is reduced, but resource wastage increases and data transmission efficiency deteriorates
Solution Approach 1:
The patent introduces a serving base station as an intermediary to handle sidelink radio link failure. The base station receives failure indication from the terminal and manages resource release, centralizing the complexity management function to improve data transmission efficiency while avoiding terminal-side complexity burden
Solution Approach 2:
The patent implements a feedback mechanism where the terminal reports radio link failure status to the serving base station. This feedback loop enables timely resource reclamation and improves data transmission efficiency by allowing the system to respond to failure conditions
2Loss of energy
If radio link failure is not detected and reported, then device complexity is reduced, but resource wastage increases
Solution Approach 1:
The terminal autonomously detects radio link failure and generates failure indication information without requiring complex external intervention. The terminal self-manages the detection and reporting process to the serving base station, enabling timely resource release while keeping the mechanism relatively simple
3Productivity
If resources are not released timely after radio link failure, then device complexity is reduced, but productivity decreases due to resource wastage
Solution Approach 1:
The serving base station acts as an intermediary that manages resource release after radio link failure. By centralizing this function at the base station level, the system achieves timely resource reclamation and improved productivity without requiring complex distributed resource management across multiple terminals

AI summary
A method and an apparatus for handling radio link failure and relates to the field of communications technologies. The method for handling radio link failure is applied to a first terminal and includes: detecting a radio link failure between the first terminal and a second terminal; and reporting an indication message of the radio link failure to a serving base station of the first terminal, where the indication message includes at least one of the following information: an identifier of radio link, an indication of radio link failure, or a cause of the radio link failure.
