Abstract
The present disclosure relates to an apparatus and a method for transmitting muting information in a wireless communication system, and to an apparatus and a method for acquiring channel state using same. In an exemplary embodiment, muting information includes: a first data field, having a serving cell for receiving from peripheral cells in a multi-cell environment, at least one of a CSI-RS pattern, the number of CSI-RS antenna ports, a CSI-RS duty cycle, and CSI-RS transmission subframe offset information, and using same for expressing the cycle and the offset of muting subframes, which pertain to information on a resource block that can generate interference between the peripheral cells and CSI-RS; and a second data field for expressing a specific muting pattern, which must be muted within the muting subframes, having either 12 bits or 28 bits that display muting application in a bitmap format.
