AI Technical Summary

Technical Problem

In 5G wireless communication, when user equipment communicates on the same time-division duplex carrier, there is cross-link interference, which makes it impossible to accurately switch to the appropriate downlink bandwidth, affecting the accuracy of measurement results.

Method used

User equipment and network equipment can use cross-link interference measurement methods to perform SRS-RSRP and CLI-RSSI measurements within the inactive downlink bandwidth portion of the DLBWP, and switch to the target DLBWP based on the measurement results. The measurement process is optimized through configuration information and measurement thresholds.

Benefits of technology

It improves the accuracy of cross-link interference measurement, ensures that user equipment communicates on a suitable DLBWP, and enhances the reliability of measurement results and the utilization efficiency of network communication resources.

Abstract

This disclosure provides a measurement method, apparatus, device, and readable storage medium applied to a wireless communication system. The method includes: receiving first configuration information from a network device; wherein the first configuration information is used to instruct at least one measurement object to perform cross-link interference (CLI) measurement on at least one DLBWP including an inactive downlink bandwidth portion (DLBWP), the at least one measurement object including at least one of SRS-RSRP and CLI-RSSI; performing CLI measurement on the at least one measurement object within the at least one DLBWP based on the first configuration information; and sending a measurement report to the network device; the measurement report including measurement results corresponding to all or some of the at least one DLBWP. This disclosure overcomes the limitation that user equipment can only perform CLI measurements on one active BWP in the same serving cell, by measuring at least one DLBWP including an inactive DLBWP in the same serving cell, thereby obtaining more accurate measurement results.
