AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
The patentability of claims 1-10 is confirmed.
1. A wireless communication terminal comprising:
a transceiver; and
a processor,
wherein the processor is configured to:
receive an aggregate MAC protocol data unit (A-MPDU) including one or more MAC service data units (MS-DUs) or aggregate MSDUs (A-MSDUs) from each of a first plurality of users, and
transmit a block ACK for acknowledgment (ACK) transmission to a second plurality of users included in the first plurality of users in response to one or more MSDUs or A-MSDUs,
wherein the block ACK includes one or more bitmap sets, and each of the one or more bitmap sets includes a starting sequence control field and a block ACK bitmap field according to a type of the block ACK indicated by a single block ACK control field,
wherein the block ACK includes the single block ACK control field while including the starting sequence control field,
wherein the block ACK bitmap field included in the each of the one or more bitmap sets indicates success or failure of reception of each of the one or more MPDUs or A-MPDU,
wherein a length of the block ACK bitmap field is variable according to the type of the block ACK,
wherein the block ACK control field indicates the type of the block ACK and a set of lengths of each of the block ACK bitmap field included in the one or more bitmap sets according to the type of the block ACK,
wherein the length of the block ACK bitmap field is determined as one of the lengths included in the set of the block ACK control field, and
wherein a number of MSDUs or A-MSDUs capable of transmitting an ACK is determined according to the length of the block ACK bitmap field.
