CROSS LINK INTERFERENCE MEASUREMENT RESOURCE CONFIGURATION AND REPORTING WITH AN INTELLIGENT REFLECTIVE SURFACE FOR INTERFERENCE MITIGATION

WIPO Patent Application WO/2023/272418

A1

A method of wireless communication at a user equipment (UE) is provided. The method includes receiving, from a scheduling entity, an indication of at least two different cross link interference (CLI) measurement resources of a message for transmission from a transmission source. The method also includes receiving, from an intelligent reflecting surface (IRS), a reflected transmission of the message originating from the transmission source, wherein the reflected transmission of the message is reflected by the IRS based on one or more IRS coefficients. The method further includes determining one or more CLI measurement parameters to generate a report. The method includes transmitting, to the scheduling entity, a CLI measurement report. The method also includes receiving, from the IRS, another reflected transmission of the message originating from the transmission source using one or more configured IRS coefficients that are configured based on the CLI measurement report.
