AI Technical Summary

Technical Problem

In existing wireless communication systems, the quasi-co-location (QCL) relationship between the low-power processor and the main radio processor is difficult to configure effectively, resulting in low accuracy and efficiency of signal strength measurement and CSI reporting, especially in the synchronization and coordination between the low-power wake-up signal (WUS) and the main radio signal.

Method used

By configuring the QCL relationship between the low-power processor and the main radio processor, utilizing the spatial filter relationship between the low-power wake-up signal (LP-WUS) and the main reference signal, and combining the TCI status table and inter-processor communication, accurate measurement and transmission of low-power CSI reports can be achieved.

Benefits of technology

It improves the accuracy of signal strength measurement and the efficiency of CSI reporting for low-power processors, optimizes the reception and synchronization process of low-power wake-up signals, and enhances the overall performance of wireless communication systems.

Abstract

Aspects of the present disclosure relate to receiving (602) configuration information associated with a quasi-co-location (QCL) relationship between a low-power transmission and a source reference signal, wherein the low-power transmission is configured to be received by a low-power processor and the source reference signal is configured to be received by a primary radio processor; measuring (604), using the low power processor or the main radio processor, a signal strength associated with the low power transmission; preparing (606) a low power channel state information (CSI) report based on the measured signal strength; and transmitting (608) the low power CSI report.
