Method for transmitting and receiving physical downlink shared channel in wireless communication system, and device therefor

A user equipment (UE) operating in a wireless communication system, the UE comprising:

• one or more transceivers;
• one or more processors;
• and
• one or more memories for storing instructions for operations executed by the one or more processors and coupled to the one or more processors;
• wherein the operations comprising:
• receiving configuration information,
• wherein the configuration information includes information for a plurality of transmission configuration indication (TCI) states;
• receiving an activation command,
• wherein the activation command is used to map up to 8 TCI states of the plurality of TCI states to codepoints of a TCI field;
• receiving downlink control information (DCI) including the TCI field;
• and
• receiving physical downlink shared channel (PDSCH) transmission occasions of a same transport block (TB) based on a codepoint of the TCI field,
• wherein, based on the configuration information including information for a repetition scheme set to a time division multiplexing (TDM) scheme, a number of the PDSCH transmission occasions is determined based on a number of TCI states mapped to the codepoint of the TCI field and the PDSCH transmission occasions are received in a slot, and
• wherein, based on the configuration information including information for a repetition number, the number of the PDSCH transmission occasions is determined based on the repetition number and the PDSCH transmission occasions are received in consecutive slots.

A base station operating in a wireless communication system, the base station comprising:

• one or more transceivers;
• one or more processors;
• and
• one or more memories for storing instructions for operations executed by the one or more processors and coupled to the one or more processors;
• wherein the operations comprising:
• transmitting, to a user equipment (UE), configuration information,
• wherein the configuration information includes information for a plurality of transmission configuration indication (TCI) states;
• transmitting, to the UE, an activation command,
• wherein the activation command is used to map up to 8 TCI states of the plurality of TCI states to codepoints of a TCI field;
• transmitting, to the UE, downlink control information (DCI) including the TCI field;
• and
• transmitting, to the UE, physical downlink shared channel (PDSCH) transmission occasions of a same transport block (TB) based on a codepoint of the TCI field,
• wherein, based on the configuration information including information for a repetition scheme set to a time division multiplexing (TDM) scheme, a number of the PDSCH transmission occasions is determined based on a number of TCI states mapped to the codepoint of the TCI field and the PDSCH transmission occasions are transmitted in a slot, and
• wherein, based on the configuration information including information for a repetition number, the number of the PDSCH transmission occasions is determined based on the repetition number and the PDSCH transmission occasions are transmitted in consecutive slots.
