AI Technical Summary

Technical Problem

The terminal device immediately releases channel measurement resources and CSI processing unit after completing CSI reporting, which makes it impossible to perform performance monitoring and complete the performance monitoring process based on inference results.

Method used

Extend the activation time of the channel measurement resources corresponding to the first CSI report and/or the time that the first CSI report occupies the CSI processing unit, so that the terminal device does not immediately release resources after completing the first CSI report, in order to support the subsequent performance monitoring process.

Benefits of technology

This ensures that terminal devices can retain CSI measurement results and reported content, supporting subsequent performance monitoring processes and improving the accuracy and efficiency of CSI feedback.

Abstract

Provided are a communication method and a communication device. The communication method comprises: a terminal device performs first CSI reporting on the basis of the configuration of a network device; when the first CSI reporting is associated with second CSI reporting, an activation time of a channel measurement resource corresponding to the first CSI reporting comprises at least one time domain resource unit subsequent to the first CSI reporting, and / or a time during which the first CSI reporting occupies a CSI processing unit comprises at least one time domain resource unit subsequent to the first CSI reporting, wherein the second CSI reporting is used for feeding back a performance monitoring result associated with the first CSI reporting.
