Wireless communication method using frame aggregation and wireless communication terminal using same

A wireless communication terminal comprising:

• a transceiver;
• and
• a processor,
• wherein the processor is configured to:
• transmit a frame including one or more medium access control protocol data unit (MPDU)s, and
• receive an acknowledgement frame related to Ack or Nack for the one or more MPDUs in response to the frame through the transceiver,
• wherein the acknowledgement frame includes i) one block ack control field related to configuration of the acknowledgement frame and ii) one or more bitmap sets based on the block ack control field,
• wherein each of the one or more bitmap sets includes a starting sequence control subfield and a block ack bitmap subfield, and
• wherein a length of the block ack bitmap subfield included in each of the one or more bitmap sets is variable based on the block ack control field.
