Method for operating terminal and base station in wireless communication system supporting unlicensed band, and device supporting same

A method of operating a base station in a wireless communication system supporting an unlicensed band, the method comprising:

• transmitting, through higher layer signaling, configuration information related to one or more of reception of one or more downlink (DL) signals or transmission of one or more uplink (UL) signals to a terminal on a resource not configured either as a DL resource or as a UL resource;
• performing a channel access procedure (CAP) for transmission of downlink control information (DCI) including slot format indicator (SFI) information through the unlicensed band;
• based on the configuration information being related to the reception of the one or more DL signals and the DCI being transmitted through the unlicensed band based on the CAP, transmitting the one or more DL signals to the terminal through the unlicensed band only when the SFI information indicates that the resource for the reception of the one or more DL signals is a DL resource;
• and
• when the configuration information is related to the transmission of the one or more UL signals, receiving the one or more UL signals from the terminal through the unlicensed band, regardless of whether the DCI is transmitted through the unlicensed band based on the CAP.

A terminal operating in a wireless communication system supporting an unlicensed band, the terminal comprising:

• at least one radio frequency (RF) module;
• at least one processor;
• and
• at least one memory operatively connected to the at least one processor and configured to store instructions causing, when executed, the at least one processor to perform the following operation,
• wherein the following operation comprises:
• receiving, through higher layer signaling, configuration information related to one or more of reception of one or more downlink (DL) signals or transmission of one or more uplink (UL) signals on a resource not configured either as a DL resource or as a UL resource by controlling the at least one RF module;
• performing physical downlink control channel (PDCCH) monitoring in the unlicensed band for an on duration by controlling the at least one RF module, based on discontinuous reception (DRX) being configured for the terminal;
• based on the configuration information related to the reception of the one or more DL signals being received, and downlink control information (DCI) including slot format indicator (SFI) information being detected through the PDCCH monitoring, performing the reception of the one or more DL signals on the DL resource in the unlicensed band by controlling the at least one RF module only when the SFI information indicates that the resource for the reception of the one or more DL signals is a DL resource;
• and
• based on the configuration information related to the transmission of the one or more UL signals being received, performing the transmission of the one or more UL signals through the unlicensed band by controlling the at least one RF module, regardless of whether the DCI is detected through the PDCCH monitoring.
