Terminal Delay Compensation Method Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face unclear methods for implementing delay compensation using timing advance (TA)-based and round trip time (RTT)-based delay compensation manners, which hinders effective reduction of transmission delays.
Innovation Solution
A communication method where a terminal device determines a target delay compensation manner based on a configuration message received from a network device, selecting between TA-based and RTT-based methods based on the presence and status of configuration and RTT information to optimize delay compensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If multiple delay compensation manners (TA-based and RTT-based) are introduced to reduce transmission delays, then transmission delay reduction capability is improved, but implementation clarity and method selection are worsened
Solution Approach 1:
The patent implements dynamic method selection where the terminal device adapts between TA-based and RTT-based delay compensation manners based on real-time configuration messages from the network device. The system transitions from static to dynamic operation, allowing the terminal to switch compensation methods according to network conditions and capability indications, thereby resolving the contradiction between having multiple compensation methods and maintaining clear implementation guidance
Solution Approach 2:
The patent employs feedback mechanisms where the terminal device sends capability information to the network device indicating whether it supports RTT measurement and calculation. The network device then provides configuration messages that guide the terminal's delay compensation method selection. This closed-loop feedback system ensures clear method selection while enabling appropriate delay compensation, addressing both the need for multiple methods and implementation clarity
2Adaptability or versatility
If the terminal device determines delay compensation manner autonomously based on configuration messages, then adaptability to different network conditions is improved, but device complexity increases
Solution Approach 1:
The patent divides the delay compensation system into distinct functional segments: capability indication (terminal to network), configuration message transmission (network to terminal), and method determination (terminal based on configuration). This segmentation allows the terminal to implement adaptability through modular operations rather than complex integrated logic, reducing overall device complexity while maintaining flexibility
Solution Approach 2:
The terminal device performs self-determination of the delay compensation manner by autonomously processing configuration messages and selecting appropriate methods (TA-based or RTT-based) based on its capabilities and network instructions. This self-service approach enables adaptability without requiring complex centralized control, as the terminal independently makes determination decisions based on received configurations
