Abstract:
1. A method for transmitting a signal in a wireless communication system, the method performed in a single user equipment (UE) comprising: receiving, at the single UE, via a physical downlink control channel (PDCCH), downlink control information (DCI) including a single cyclic shift value; and transmitting, at the single UE, in response to the DCI, each of demodulation reference signals (DMRSs) for a physical uplink shared channel (PUSCH) through at least two antennas including a first antenna and a second antenna by cyclic shifting the DMRSs based on at least two different cyclic shift values including a first cyclic shift value for the first antenna and a second cyclic shift value for the second antenna, wherein the first and second cyclic shift values are determined by the single cyclic shift value, and an offset between the first and second cyclic shift values is pre-defined based on a number of the plurality of antennas and a number of available cyclic shift values.
