Abstract
A wireless communication system, a method, and an apparatus for transmitting a multi-user Multiple Input Multiple Output (MIMO) signal in a wireless communication system for supporting a relay. A method for transmitting a demodulation reference signal (DMRS) for downlink multi-user MIMO transmission, the method including mapping a DMRS for first and second layers on a downlink physical resource block according to first and second DMRS patterns, respectively; and transmitting the downlink physical resource block. In the downlink physical resource block, a resource element corresponding to the second DMRS pattern can be punctured on the first layer and resource element corresponding to the first DMRS pattern can be punctured on the first layer and a resource element corresponding to the first DMRS pattern can be punctured on the second layer.
