1. An operation method of a station (STA) multi-link device (MLD) supporting multi-link in a communication system, comprising:
transmitting, by a first STA affiliated with the STA MLD, a first frame using a first link among the multi-link;
in response to the STA MLD not supporting simultaneous transmit and receive (STR) operations, performing, by a second STA affiliated with the STA MLD, a carrier sensing operation in a first time period according to a first timer after a blindness period on a second link among the multi-link; and
performing, by the second STA affiliated with the STA MLD, an operation for a transmission after the first time period on the second link,
wherein the blindness period occurs on the second link due to transmission of the first frame on the first link, and the blindness period is a period in which the carrier sensing operation is impossible.
