AI Technical Summary

Technical Problem

In the scenario where RIS is deployed on mobile vehicles, frequent codebook replacement leads to increased measurement overhead and signaling overhead, and codebook updates are delayed and have low accuracy, which affects the signal quality stability of user equipment in the vehicle.

Method used

By acquiring mobility information, determining the target codebook based on the preset codebook table, and sending codebook update instructions to RIS, reducing real-time detection and measurement, and reducing the time delay and error of codebook update.

Benefits of technology

The measurement and signaling overhead of codebook updates is reduced, the time delay of codebook updates is reduced, the accuracy of codebook updates is improved, and the signal quality of user equipment in the vehicle is stable.
