Abstract: A method by a wireless transmitting device for distinguishing between a quality of service (QoS) management frame and a non-QoS management frame is described. The method includes generating a frame that includes a frame header, wherein the frame header includes a frame control field, wherein the frame control field includes a partial traffic identifier or subtype (PTID/subtype) subfield, wherein the PTID/subtype subfield indicates whether the frame is a quality of service (QoS) management frame or a non-QoS management frame and transmitting the frame through a wireless medium.

Abstract: Disclosed are a method and an apparatus for transmitting and receiving data in a Wireless Local Area Network (WLAN) system. A method for transmitting data may comprise generating a physical layer (PHY) frame including a payload in which a plurality of Medium Access Control protocol data units (MPDUs) are multiplexed; and transmitting the PHY frame, wherein the PHY frame includes information on subcarriers occupied by each of the plurality of MPDUs in an Orthogonal Frequency Division Multiplexing (OFDM) symbol of the payload. Therefore, data transmission efficiency in a WLAN system can be enhanced.

Abstract: An Acknowledgment (ACK) method is provided by a receiving device in a Wireless Local Area Network (WLAN). 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.

Abstract: A method performed by a wireless device operating in a wireless network. The method includes receiving a wake-up receiver frame, wherein the wake-up receiver frame includes a continuous frame field that indicates whether a further wake-up receiver frame comes after the wake-up receiver frame and determining whether the further wake-up receiver frame exists based on a content of the continuous frame field.

Abstract: A method for determining a number of symbols in a data field of a physical layer (PHY) protocol data unit (PPDU) is described. The method includes determining, by a wireless transmitting device, whether aggregation is to be applied to the PPDU; determining, by the wireless transmitting device, whether a PSDU length indication of the data field for the PPDU is greater than zero; selecting, by the wireless transmitting device, a first value in response to determining that (1) aggregation is not to be applied to the PPDU and (2) the PSDU length indication for the PPDU is greater than zero; and calculating, by the wireless transmitting device, the number of symbols in the data field of the PPDU based on the first value, wherein the first value is the PSDU length indication.
