receiving, from a base station, a radio resource control (RRC) message including configuration information for an uplink demodulation reference signal (DMRS);
receiving, from the base station, downlink control information (DCI) for scheduling a physical uplink shared channel (PUSCH);

wherein the DCI includes information related to a time-domain orthogonal cover code (OCC) for the uplink DMRS among a set of time-domain OCCs, and
wherein a length of respective time-domain OCCs depends on the actual number of the one or more symbols for the uplink DMRS.
