## Abstract

Examples of user equipments (UEs) are described. A UE includes receiving circuitry configured to receive first information to configure one or more channel state information-reference signals (CSI-RS) for tracking and second information to configure time domain correlation related information. The UE also includes transmitting circuitry configured to transmit a channel state information (CSI) report including the time domain correlation related information. A first parameter trs-Info is included in the first information. A second parameter indicates one of a periodic CSI report, semi-persistent CSI report, and aperiodic CSI report. The time domain correlation related information is measured by the one or more CSI-RS for tracking. The CSI report including the time domain correlation related information is transmitted based on the second parameter.
