Title: USER EQUIPMENT AND METHOD OF CONTROL OF CHANNEL STATE INFORMATION (CSI) REPORTING
Abstract:
A user equipment (UE) includes a memory that stores a state of semi- persistent Channel State Information (CSI)-Reference Signal (RS) as a first state where the semi-persistent CSI-RS is activated or a second state where the semi-persistent CSI-RS is deactivated; a receiver that receives a predetermined trigger information; and a processor that changes the state in the memory and causes a transmitter to perform aperiodic CSI reporting based on the predetermined trigger information.
