Abstract
A method and a user equipment (UE) for transmitting a demodulation reference signal for a physical uplink shared channel (PUSCH) in a wireless communication system are discussed. The method according to an embodiment includes configuring a virtual cell identity (ID) which is different from a physical cell ID; generating a base sequence by using the virtual cell ID; obtaining a cyclic shift hopping pattern for each slot by using a UE-specific parameter; generating the demodulation reference signal for the PUSCH by using the base sequence and the cyclic shift hopping pattern for each slot; and transmitting the demodulation reference signal for the PUSCH to an eNodeB (eNB).
