The present disclosure relates to the field of wireless communication technology, and more specifically, to a measurement method, device and readable storage medium for switching a down link band width part (DLBWP).
In the wireless communication technology such as the 5th Generation Mobile Communication Technology (5G), a cross-link interference (CLI) may occur between user equipments (UEs) when conducting communication simultaneously (including transmitting and/or receiving) on the same time-division duplex (TDD) carrier according to different scheduling commands.
In order to mitigate the cross-link interference, the UE measures the uplink Sounding Reference Signal-Reference Signal Receiving Power (SRS-RSRP) and/or Cross Link Interference-Received Signal Strength Indication (CLI-RSSI).
For example, a group of aggressor UEs transmits data on the same TTD carrier, while another group of victim UEs receives data on this same TTD carrier. The UE measures the SRS-RSRP and/or CLI-RSSI and reports the measurement result, and the network device (e.g., gNB) may evaluate the interference of the aggressor UE to the victim UE based on the measurement result. The aggressor UE transmits an SRS signal with a set configuration, and the victim UE performs an interference measurement on the SRS signal with a corresponding configuration.

The user device 102 shown above may be a user equipment (UE), a terminal, an access terminal, a terminal unit, a terminal station, a mobile station (MS), a remote station, a remote terminal, a mobile terminal, a wireless communication device, a terminal agent, or a user apparatus.
