Method and device for transmitting and receiving physical channel in wireless communication system

A terminal of receiving a PDSCH (physical downlink shared channel) in a wireless communication system, the terminal comprising:

• at least one transceiver for transmitting and receiving a wireless signal;
• and
• at least one processor for controlling the at least one transceiver,
• wherein the at least one processor configured to:
• receive, from a base station, configuration information related to a plurality of training reference signals for training of an artificial intelligence (AI)/machine learning (ML) model;
• receive, from the base station, the plurality of training reference signals;
• receive, from the base station, control information for scheduling the PDSCH;
• and
• receive, from the base station, the PDSCH based on an inference derived for a demodulation reference signal (DMRS) of the PDSCH from an AI/ML model trained using one or more training reference signals among the plurality of training reference signals,
• wherein the configuration information or the control information includes information on the one or more training reference signals corresponding to the DMRS.

A base station of receiving a PUSCH (physical uplink shared channel) in a wireless communication system, the terminal comprising:

• at least one transceiver for transmitting and receiving a wireless signal;
• and
• at least one processor for controlling the at least one transceiver,
• wherein the at least one processor configured to:
• transmit, to a terminal, configuration information related to a plurality of training reference signals for training of an artificial intelligence (AI)/machine learning (ML) model;
• receive, from the terminal, the plurality of training reference signals;
• transmit, to the terminal, control information for scheduling the PUSCH;
• and
• receive, from the terminal, the PUSCH based on an inference derived for a demodulation reference signal (DMRS) of the PUSCH from an AI/ML model trained using one or more training reference signals among the plurality of training reference signals,
• wherein the configuration information or the control information includes information on the one or more training reference signals corresponding to the DMRS.
