Method for transmitting and receiving plurality of physical downlink shared channels in wireless communication system, and device for same

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

• a transceiver configured to transmit and receive radio signals;
• and
• a processor functionally coupled to the transceiver and configured to perform operations comprising:
• receiving configuration information including information related to a number of a plurality of Physical Downlink Shared Channel (PDSCH) transmission occasions,
• receiving PDSCH configuration information including information for a plurality of transmission configuration indication (TCI) states,
• receiving downlink control information (DCI), wherein one or more TCI states among the plurality of TCI states are indicated based on the DCI, and
• based on the one or more TCI states, receiving the plurality of PDSCH transmission occasions in consecutive slots based on the number of the plurality of PDSCH transmission occasions,
• wherein, based on a number of the one or more TCI states being two, the plurality of PDSCH transmission occasions include i) at least one PDSCH transmission occasion to which a first TCI state is applied and ii) at least one PDSCH transmission occasion to which a second TCI state is applied, and
• wherein, based on the number of the plurality of PDSCH transmission occasions being larger than two, the second TCI state is applied to two consecutive PDSCH transmission occasions after two consecutive PDSCH transmission occasions to which the first TCI state is applied.

A base station (BS) configured to operate in a wireless communication system, comprising:

• a transceiver configured to transmit and receive radio signals, and
• a processor functionally coupled to the transceiver and configured to perform operations comprising:
• transmitting, to a user equipment (UE), configuration information including information related to a number of a plurality of Physical Downlink Shared Channel (PDSCH) transmission occasions,
• transmitting, to the UE, PDSCH configuration information including information for a plurality of transmission configuration indication (TCI) states,
• transmitting, to the UE, downlink control information (DCI), wherein one or more TCI states among the plurality of TCI states are indicated based on the DCI, and
• based on the one or more TCI states, transmitting, to the UE, the plurality of PDSCH transmission occasions in consecutive slots based on the number of the plurality of PDSCH transmission occasions,
• wherein, based on a number of the one or more TCI states being two, the plurality of PDSCH transmission occasions include i) at least one PDSCH transmission occasion to which a first TCI state is applied and ii) at least one PDSCH transmission occasion to which a second TCI state is applied, and
• wherein, based on the number of the plurality of PDSCH transmission occasions being larger than two, the second TCI state is applied to two consecutive PDSCH transmission occasions after two consecutive PDSCH transmission occasions to which the first TCI state is applied.
