Solution Overview
Problem
High-speed mobile communication environments, such as in vehicles, experience degradation in wireless link performance due to incomplete updates of channel state information between relay stations and base stations, leading to poor service quality.
Innovation Solution
A method where a first communication node receives reference information from a second communication node, determining link information based on parameters like antenna number, spacing, movement speed, and geographical position to optimize wireless link communication, ensuring timely updates and maintaining channel quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If relay station forwards data between base station and terminal in high-speed mobile vehicles, then service quality can be improved, but channel state information becomes outdated causing wireless link performance degradation
Solution Approach 1:
The patent applies preliminary action by having the receiving party send reference information (including antenna parameters, movement speed, position) before actual data transmission. This allows the transmitting party to pre-calculate link information and predict channel characteristics, ensuring timely updates even in high-speed mobile environments where channel conditions change rapidly.
2Productivity
If large-scale antenna array technology forms thin spot beam, then spectrum efficiency is enhanced, but movement speed of receiving party is heavily limited
Solution Approach 1:
The patent sends reference information including antenna parameters and movement speed before transmission, allowing the transmitting party to pre-calculate link information and predict future channel characteristics, enabling tracking of high-speed moving targets
Solution Approach 2:
The patent dynamically adjusts link information based on the receiving party's movement speed and position. By continuously updating link information using reference information about antenna parameters and movement characteristics, the system adapts to high-speed movement while maintaining focused beam transmission for spectrum efficiency
3Speed
If receiving party moves at high speed, then mobility is improved, but channel characteristics completely change causing receiving to leave coverage of spot beam
Solution Approach 1:
The receiving party sends reference information including movement speed and position before transmission, enabling the transmitting party to pre-calculate link information and predict channel characteristics, ensuring the receiving party remains within beam coverage even at high speeds
Solution Approach 2:
The patent implements feedback by having the receiving party continuously provide reference information about its movement and antenna parameters. This feedback loop allows the transmitting party to continuously update link information and adjust transmission parameters, maintaining reliable wireless links during high-speed movement
