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

A user equipment (UE) receiving a physical downlink shared channel (PDSCH) in a wireless communication system, the UE comprising:

• one or more transceivers;
• one or more processors configured to control the one or more transceivers;
• and
• one or more memories operably connected to the one or more processors,
• wherein the one or more memories store instructions, based on being executed by the one or more processors, performing operations,
• wherein the operations comprise:
• receiving configuration information related to the PDSCH, wherein Transmission Configuration Indicator states (TCI states) related to the PDSCH are configured based on the configuration information;
• receiving a message representing an activation of the TCI states based on the configuration information based on the configuration information, wherein a component carrier (CC) related to the activation is indicated based on the message;
• receiving downlink control information (DCI) scheduling the PDSCH;
• and
• receiving the PDSCH based on the DCI,
• wherein, based on the message, one or more TCI states among the TCI states based on the configuration information are activated for the indicated CC,
• wherein, based on the DCI, one of the one or more TCI states is indicated,
• wherein, based on that frequency resources related to the activation of the TCI states based on the configuration information are determined based on the message:
• the one or more TCI states are activated for the frequency resources,
• the frequency resources are based on at least one of a plurality of CCs or a plurality of bandwidth parts (BWPs),
• the frequency resources are determined based on one of a plurality of lists which are pre-configured via a higher layer signaling,
• each of the plurality of lists is configured to include one or more CCs,
• one of the plurality of lists is determined based on a field included in the message,
• the field represents information based on a pre-configured number of bits, and
• the information based on the pre-configured number of bits is related to an ID for one of the plurality of lists.
