Abstract
The disclosure relates to a method, performed by a user equipment (UE), of transmitting or receiving signals in a wireless communication system, and in an embodiment, the UE transmits, to a base station (BS), UE capability information regarding sequence initialization of a demodulation reference signal (DMRS), receives, from the BS, DMRS configuration information determined based on the UE capability information, and receives the DMRS from the BS based on the DMRS configuration information, wherein the DMRS is generated based on a sequence initialization parameter determined based on a code division multiplexing (CDM) group identifier included in the DMRS configuration information.
