Apparatus and method for transmitting muting information, and apparatus and method for acquiring channel state using same

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 to 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.

         20 . A base station to transmit Channel State Information-Reference Signal (CSI-RS) information, comprising:
 a processor configured to generate CSI-RS information including an offset of zero power transmission subframes and a CSI-RS zero power configuration list having an n-bit bitmap, wherein each bit of the n-bit bitmap indicating whether to apply zero power transmission in the zero power transmission subframes; and   a transmitter configured to transmit the CSI-RS information to a user equipment.   
     
     
         21 . A method of transmitting Channel State Information-Reference Signal (CSI-RS) information, the method comprising:
 generating CSI-RS information including an offset of zero power transmission subframes and a CSI-RS zero power configuration list having an n-bit bitmap, wherein each bit of the n-bit bitmap indicating whether to apply zero power transmission in the zero power transmission subframes; and   transmitting the CSI-RS information to a user equipment.
