1. A base wireless communication terminal for communicating with a wireless communication terminal wirelessly, the base wireless communication terminal comprising:
a transceiver; and
a processor,
wherein the processor is configured to:
transmit, by using the transceiver, a trigger frame to the wireless communication terminal,
receive, by using the transceiver, a PLCP protocol data unit (PPDU) in response to the trigger frame from the wireless communication terminal, wherein the PPDU includes a medium access control (MAC) frame,
when the wireless communication terminal is associated with the base wireless communication terminal, insert an association identifier corresponding to an association of the wireless communication terminal with the base wireless communication terminal into a first field of a multi-station Block ACK frame and set a value of second field of the multi-station Block ACK frame based on at least one MAC frame received from the wireless communication terminal, wherein the multi-station Block ACK frame indicates whether at least one of MAC frames transmitted from at least one of wireless communication terminals is received,
when the wireless communication terminal is unassociated with the base wireless communication terminal, insert an identifier for an unassociated wireless communication terminal into the first field and a MAC address of the wireless communication terminal into the second field, and
transmit the multi-station Block ACK frame,
wherein the identifier for an unassociated wireless communication terminal is not allocated through an association of a wireless communication terminal with the base wireless communication terminal and not used for an associated wireless communication terminal, and
wherein a value of the identifier for an unassociated wireless communication terminal is out of a range of values that are predefined for the association identifier and larger than 2007.
