摘要：Disclosed are an apparatus for Channel State Information-Reference Signal (CSI-RS) allocation and a method for CSI-RS transmission using the same in a wireless
communication system. A CSI-RS for each antenna port is allocated to REs or subcarrierson a basis of a symbol or symbol axis in a subframe or Resource Block (RB), and isallocated in such a manner that a distance between neighboring CSI-RS allocation REs orsubcarriers may be 3 REs or subcarriers. Accordingly, in the range of following CSI-RStransmission overhead, CSI-RSs are allocated to a time-frequency resource domain insuch a manner so as to have perfect orthogonality or quasi-orthogonality according tocells or cell groups. Then, the CSI-RSs, which have been allocated to the time-frequencyresource domain, are transmitted.
