Abstract

The present invention 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. One embodiment of the present invention provides technology for generating and transmitting muting information comprising: 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. By using the present invention, the muting information, which can avoid interference between the peripheral cells and the CSI-RS, can be configured and transmitted in a manner that is efficient and can minimize overhead, thereby allowing accurate and efficient decoding and, accordingly, accurate estimation of a channel state.
