Title: METHOD OF ACQUIRING CHANNEL STATE INFORMATION (CSI), USER EQUIPMENT (UE), AND TRANSMISSION AND RECEPTION POINT (TRP)
Abstract:
A method of acquiring Channel State Information (CSI) includes transmitting, from a Transmission and Reception Point (TRP) to a User Equipment (UE), information indicating that both of a Resource setting and a CSI reporting setting are commonly set to activation or deactivation. The Resource setting being set to the activation causes the UE to assume that CSI-Reference Signals (RSs) are to be transmitted from the TRP. The CSI reporting setting being set to the activation triggers the UE to perform CSI reporting. The method further includes receiving, with the UE, the CSI-RSs transmitted in accordance with a predetermined type of time domain behavior when the Resource setting is set to the activation. The method further includes performing, with the UE, the CSI reporting in accordance with the predetermined type of time domain behavior when the CSI reporting setting is set to activation.
