Flexible HARQ Timing Adaptation for Wireless Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication techniques set a fixed Hybrid Automatic Repeat Request (HARQ) timing for all terminals, which does not account for varying processing delays and performance levels over time, leading to inefficient resource utilization.
Innovation Solution
A method and device that dynamically determine HARQ timings for individual terminals based on their processing capabilities, the base station's processing capability, and network requirements, allowing timings to vary by terminal and over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed timing is set for all terminals based on processing delays, then the system ensures basic compatibility and reliability, but terminals with higher performance cannot be used effectively, resulting in resource waste
Solution Approach 1:
The patent applies dynamics by transitioning from a fixed HARQ timing configuration to a dynamic one where the timing can be adjusted based on terminal performance. The base station determines the timing value adaptively for each terminal based on reported processing delay parameters, allowing the system to optimize for high-performance terminals while maintaining compatibility for others.
Solution Approach 2:
The patent changes the parameter of HARQ timing from a fixed system-wide value to a variable parameter that can be individually configured per terminal. The base station receives processing delay parameters from terminals and uses these to determine appropriate timing values, effectively changing the timing parameter to match terminal capabilities.
2Ease of operation
If a same timing is set for all terminals, then the system maintains simplicity and ease of management, but actual performance differences among terminals are not accounted for, leading to inefficient resource usage
Solution Approach 1:
The patent segments the unified timing configuration into individual terminal-specific timing configurations. Instead of managing a single timing value for all terminals, the base station now manages separate timing values for each terminal based on their individual processing delay parameters, allowing optimized resource utilization while maintaining centralized management.
3Stability of the object's composition
If a fixed timing is set for terminals, then the configuration remains stable over time, but actual performance of terminals may vary over time causing the terminal to be underutilized during high-performance periods
Solution Approach 1:
The patent implements feedback by having terminals report their processing delay parameters to the base station. This feedback mechanism allows the base station to continuously monitor terminal performance and adjust the HARQ timing accordingly, ensuring that the timing configuration remains optimal even as terminal performance varies over time.
