Abstract

Provided is a method and apparatus for configuring a reference signal (RS), and for transmitting and receiving the RS, in a wireless communication system. When an RS for a predetermined UE is transmitted, RS information may be configured to include a number of layers assigned to the predetermined UE, an antenna port and a scrambling ID for each of the assigned layers, and a total number of layers assigned to the predetermined UE or the UEs, including the predetermined UE, which use the same resource region. Accordingly, when the RS is decoded in the predetermined UE in a MU-MIMO system, the predetermined UE may be aware of interference caused by other UEs and may remove interference and thus, performance of the entire system may be improved.
