1. A method performed by a User Equipment (UE), the method comprising:
receiving, from a base station, a Radio Resource Control (RRC) signaling comprising first information related to a first position for a first Demodulation Reference Signal (DMRS) for a Physical Uplink Shared Channel (PUSCH);
receiving, from the base station, a first Downlink Control Information (DCI) format for scheduling the PUSCH, the first DCI format comprising second information related to a first time duration; and
determining, based on the first information and the second information, the first position where the UE transmits the first DMRS for the PUSCH in addition to a second DMRS for the PUSCH at a second position in the first time duration.
