Abstract:
The present invention discloses a channel state information (CSI) measurement method through which a user equipment (UE) recognizes a resource pattern applied to a current CSI measurement resource through blind detection or dynamic signaling and performs CSI measurement when an evolved Node B (eNB) or the UE performs LBT (Listen-Before-Talk) based signal transmission and the eNB transmits CSI measurement resources (e.g., CRS/CSI-RS/CSI-IM) by applying one of a plurality of resource patterns thereto, and a UE performing the same.
