18 Claims

1. A wireless communication terminal, comprising:

a processor; and

a communication unit,

wherein the processor is configured to:

transmit, through the communication unit, a physical layer protocol data unit (PPDU),

wherein the PPDU includes a medium access control protocol data unit (MPDU), or an aggregate MPDU (A-MPDU) including one or more MPDUs, and

wherein the A-MPDU includes at least one MPDU delimiter information and one or more traffic identifier (TID) related to the one or more MPDUs, and

receive, through the communication unit, a response frame in response to the PPDU,

wherein a format of the response frame is determined as one of an Ack frame, a Compressed Block Ack frame, or a Multi-STA Block Ack frame based on at least one of the MPDU delimiter information or a number of at least one TID for successfully received MPDUs among the one or more TIDs,

wherein the Ack frame is used when the PPDU includes only one MPDU or only one MPDU soliciting an immediate response among the one or more MPDUs, and

wherein the Compressed Block Ack frame and the Multi-STA Block Ack frame are used when the PPDU includes two or more MPDUs.
