- Apparatus and Method for Transmitting Muting Information regarding Channel State Information-Reference Signal and Channel State Acquisition Apparatus and Method using the same

摘要

The present invention relates to an apparatus and method for transmitting CSI-RS muting information in a wireless communication system, and an apparatus and method for acquiring a channel state using the same. In an exemplary embodiment of the present invention, in a multi-cell environment, a serving cell receives a CSI-RS pattern, a CSI-RS antenna port number, a CSI-RS transmission period, And generates and transmits muting information for a resource region that can cause interference with a CSI-RS of the neighboring cell using the generated CSI-RS. By using the present invention, accurate and efficient CSI-RS decoding in the UE can be achieved by efficiently constructing and transmitting muting information that can avoid interference with a CSI-RS of a neighboring cell in a scheme that can efficiently reduce overhead as much as possible So that channel state estimation can be performed precisely.
