摘要： 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.
