The receiving device receives a plurality of data units having a plurality of Traffic Identifiers (TIDs) and transmits an ACK frame including a plurality of ACK information fields for at least part of the plurality of data units. An ACK information field for a data unit satisfying a first condition among the plurality of ACK information fields includes a Traffic Identifier (TID) and a block ACK bitmap indicating whether the data unit has been successfully received. An ACK information field for a data unit satisfying a second condition and having been successfully received among the plurality of ACK information fields includes the first TID and does not include a block ACK bitmap."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Acknowledgement method and multi user transmission method","description":"An Acknowledgment (ACK) method is provided by a receiving device in a Wireless Local Area Network (WLAN).
