Method of operating terminal and base station in wireless communication system and apparatus supporting same

A user equipment (UE) configured to operate in a wireless communication system, comprising:

• at least one transmitter;
• at least one receiver;
• at least one processor;
• and
• at least one memory operably connected to the at least one processor and configured to store instructions causing, when executed, the at least one processor to perform operations comprising:
• receiving, from a base station (BS), a synchronization signal/physical broadcast channel (SS/PBCH) block including an SS and a PBCH;
• performing a channel access procedure based on the received SS/PBCH block;
• receiving, from the BS, downlink control information (DCI) including a plurality of transmission configuration indicator (TCI) states;
• obtaining, from the BS, configuration information related to repetitive transmission of a plurality of data, the plurality of data being based on same information;
• receiving, from the BS, downlink control information (DCI) including a plurality of transmission configuration indicator (TCI) states;
• receiving the plurality of data via a plurality of physical downlink shared channels (PDSCHs) based on the DCI and the configuration information;
• obtaining resource information for the plurality of PDSCHs based on the DCI and the configuration information,
• wherein the plurality of PDSCHs includes a first PDSCH and a second PDSCH;
• obtaining first demodulation reference signal (DMRS) port information for the first PDSCH based on information included in the DCI;
• obtaining second DMRS port information for the second PDSCH based on the information included in the DCI;
• and
• receiving the first PDSCH and the second PDSCH based on the first DMRS port information and the second DMRS port information.
