## Abstract

The present disclosure discloses a method of operating a terminal and a base station in a wireless communication system and an apparatus supporting same. According to an embodiment applicable to the present disclosure, a terminal may establish a connection with a base station on the basis of a synchronization signal/physical broadcast channel (SS/PBCH) block received from the base station. Then, the terminal is set to a transmission mode in which data generated from identical information is transmitted by the base station through a plurality of physical downlink shared channels (PDSCHs), and on the basis of the aforementioned, the terminal may obtain resource information through which the data is transmitted through the plurality of PDSCHs, and obtain related data information.

## Claims

### Claim 1

A method for operating by a user equipment (UE) in a wireless communication system, the method 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;
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.

### Claim 2 (depends on 1)

The method of claim 1, wherein the DCI includes two TCI states,

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.
