Abstract
A method is provided for transmitting a demodulation reference signal (DMRS) by a user equipment (UE) in a wireless communication system. The UE receives a cyclic shift field in an uplink scheduling assignment from a base station, allocates a first cyclic shift value of a first DMRS for a first layer and a second cyclic shift value of a second DMRS for a second layer, based on the cyclic shift field, and transmits the first DMRS and the second DMRS to the base station.
