AI Technical Summary

Technical Problem

In multiple transmit-receive-receive (MTRP) scenarios, existing technologies struggle to effectively report channel state information (CSI), particularly the accuracy and consistency of Doppler and delay-related parameters, which impacts the quality and efficiency of wireless communication.

Method used

By configuring multiple CSI-RS resource sets and TCI states, combined with Doppler reporting and delay reporting mechanisms, it is ensured that each CSI-RS resource or resource group is associated with a TRP or TCI state, and measurements and reports are performed on specific time-domain and frequency-domain resources, providing accurate feedback of Doppler and delay information.

Benefits of technology

It improves the accuracy and consistency of CSI reports, enhances the performance of wireless communication systems in multi-transmitter/receiver scenarios, and supports communication requirements with higher data rates and lower latency.

Abstract

Systems, methods, and devices for wireless communication are described. A method of wireless communication includes receiving, by a wireless device, a channel state information (CSI) report configuration. The method also includes performing, by the wireless device, a CSI report associated with a plurality of reference signals, where the CSI report indicates results of measurements of a plurality of reference signal resources configured in at least one reference signal resource set in the CSI report configuration.
