Abstract  Abstract

Provided is a method for transmitting by a user equipment (UE) a demodulation reference signal (DMRS) for a physical uplink shared channel (PUSCH) in a wireless communication system. A terminal receives a cyclic shift field which indicates a first value and a second value through a physical downlink control channel (PDCCH) from a base station generates a first DMRS sequence and a second DMRS sequence which are associated with a first layer and a second layer respectively by using a first cyclic shift and a second cyclic shift respectively which are determined based on the first value and the second value respectively and transmits the first DMRS sequence and the second DMRS sequence to the base station. Furthermore the first value and the second value are separated by a maximum value corresponding to a total number of possible cyclic shifts.
