Wireless communication method using multi-link, and wireless communication terminal using same

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

• a transceiver;
• and
• a processor configured to control the transceiver, wherein the processor is configured to:
• receive a trigger frame from an access point (AP), wherein the trigger frame is used to share a specific time, which is part or all of a transmission opportunity (TXOP) obtained by the AP, with the STA;
• and
• transmit a non-trigger-based physical layer protocol data unit (non-TB PPDU) to the AP and/or another STA within the specific time based on the trigger frame,
• wherein the non-TB PPDU includes duration information,
• wherein the duration information is set based on the specific time, and
• wherein the processor is configured to not reset a network allocation vector (NAV) based on expiration of a NAV timeout within the specific time when the NAV timeout indicating termination of the NAV and the NAV are set based on the trigger frame.
