Patent ID: 10574325

Abstract:
A method for receiving, by a user equipment (UE), a channel state information reference signal (CSI-RS) in a wireless communication system, includes receiving, from a base station, CSI-RS resource configuration information related to a numbering for a plurality of CSI-RS resources through a radio resource control (RRC) signaling, wherein the CSI-RS resource configuration information includes first CSI-RS configuration information and at least one second CSI-RS configuration information; and determining numbers for the plurality of CSI-RS resources based on the received CSI-RS resource configuration, wherein a specific CSI-RS resource among the plurality of CSI-RS resources corresponds to a value configured in the first CSI-RS configuration information, and at least one CSI-RS resource except the specific CSI-RS resource among the plurality of CSI-RS resources corresponds to a value configured in the second CSI-RS configuration information, and wherein the specific CSI-RS resource is a CSI-RS resource related to a lowest number among the plurality of CSI-RS resources.
