Abstract: Provided is a wireless communication terminal that wirelessly communicates with a base wireless communication terminal. The wireless communication terminal includes a transceiver, and a processor. The processor is configured to set an integer selected from a range of 0 to a value equal to or smaller than an OFDMA Contention Window (OCW) as a counter for random access, receive a trigger frame for triggering random access using one or more resource units (RUs) allocated for the random access from the base wireless communication terminal using the transceiver, decrement a value of the counter based on the one or more RUs allocated for the random access, randomly select one RU based on the one or more RUs allocated for the random access when the value of the counter is 0 or reaches 0, and attempt transmission to the base wireless communication terminal using the selected RU.

Abstract: Disclosed is a station communicating with a single radio multi-link device, which includes a plurality of stations operating on a plurality of links but does not support simultaneous transmission and reception by the plurality of stations. The station comprises a transmitting/receiving unit and a processor. The processor transmits a control frame to a first station of the single radio multi-link device by using the transmitting/receiving unit, receives a response to the control frame from the first station of the single radio multi-link device, and starts a null data packet (NDP) sounding sequence for the first station of the single radio multi-link device.

Abstract: Disclosed is a method for transmitting and receiving data in a non-access point (AP) multi-link device (MILD) of a wireless communication system. The non-AP MLD may perform a back off procedure for performing simultaneous transmission through a multi-link of the non-AP MLD, and simultaneously perform uplink transmission to an AP MLD through each of a first link and a second link included in the multi-link. Here, when both a first back-off counter and a second back-off counter have a value of “0”, if the transmission time of the uplink transmission in the first link is a slot boundary of a first slot that is a slot next to a slot in which the first back-off counter is “0”, the uplink transmission in the second link may be performed within a predetermined time from the transmission time of the first link.

Abstract: A wireless communication terminal communicating wirelessly with a base wireless communication terminal and unassociated with the base wireless communication terminal is disclosed. The wireless communication terminal includes: a transceiver; and a processor configured to receive, by using the transceiver, a multi-station Block ACK frame which indicates whether at least one of MAC frames transmitted from at least one of wireless communication terminals is received by using a first field of the multi-station Block ACK frame for indicating an association identifier corresponding to an association of each of the at least one of wireless communication terminals and the base wireless communication terminal, from the base wireless communication terminal, and determine whether a MAC frame transmitted from the wireless communication terminal is received by the base wireless communication terminal based on whether a second field of the multi-station Block ACK frame includes a MAC address of the wireless communication terminal.
