Abstract:
A method, device, and system for receiving a downlink signal is provided. The method includes: detecting a Channel State Information Reference Signal (CSI-RS) in a time unit #n on an unlicensed band cell; verifying whether the CSI-RS is used for Discovery RS (DRS) using an initialization value of a CSI-RS sequence of the CSI-RS; and performing a Radio Resource Management (RRM) measurement when the CSI-RS is used for the DRS. The CSI-RS is used for the DRS when an index of the time unit #n is not used for the initialization value of the CSI-RS sequence.
