Abstract: A method performed by a wireless device operating in a wireless network. The method includes generating a physical layer protocol data unit (PPDU) that includes a preamble portion and a data portion, wherein the preamble portion includes a signal field, wherein the signal field includes a bit that is set to binary ‘0’ to indicate that the data portion of the PPDU includes a wake-up receiver preamble and wake-up receiver data. The method further includes wirelessly transmitting the PPDU.

Abstract: A method performed by a wireless device functioning as a beamformee station in a wireless network to perform a sounding procedure. The method includes wirelessly receiving a null data packet (NDP) announcement frame from a beamformer station, wherein the NDP announcement frame includes an indication of whether the beamformee station should acknowledge the NDP announcement frame and responsive to determining that the NDP announcement frame includes an indication that the beamformee station should acknowledge the NDP announcement frame, wirelessly transmitting an acknowledgement frame for the NDP announcement frame to the beamformer station.

Abstract: A method is described for communicating in a network. The method includes setting a type bit in a frame to indicate whether the frame is scheduling an uplink transmission for a first set of stations or a first and second set of stations; configuring a common information field of the frame for (1) the first set of stations for the transmission and (2) when the type bit indicates, the second set of stations for the transmission; configuring a set of user information fields of the frame for (1) the first set of stations for the transmission and (2) when the type bit indicates, the second set of stations for the transmission; and transmitting the frame to (1) the first set of stations and (2) the second set of stations when the type bit indicates that the frame is scheduling for the first and second set of stations.

Abstract: A method of transmitting a frame is provided by a device in a WLAN. The device sets as additional data subcarriers some of subcarriers which are not set as data subcarriers in at least part of fields included in a frame of a legacy frame format, and allocates information to the additional data subcarriers.
