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 is described for aligning high efficiency (HE), extremely high throughput (EHT), and EHT+sub-physical layer protocol data units (sub-PPDUs) included in an aggregated PPDU (APPDU) trigger frame. The method includes aligning a preamble portion of the sub-PPDUs by applying a multi-user PPDU (MU-PPDU) format to each of the sub-PPDUs and aligning a data portion of the sub-PPDUs by including a padding subfield in each of the sub-PPDUs to produce a common length.

Abstract: A method for channel sounding for high efficiency (HE) and extreme high throughput (EHT) stations (STAs) includes receiving, by a station (STA), an aggregate physical layer protocol data unit (A-PPDU) from an access point (AP), the A-PPDU including an HE sounding null data packet (NDP) and an EHT sounding NDP, receiving, by the STA, a beamforming report poll frame (BFRP) from the AP, and receiving, by the STA, one or more compressed beamforming (BF)/channel quality indicator (CQI) frames. The HE sounding NDP or the EHT sounding NDP overlaps 242-tone resource units (RUs) corresponding to bits with a value of 1 in the bitmap of the TXVECTOR parameter INACTIVE_SUBCHANNELS or overlaps a punctured center 26-tone RU of an HE sounding NDP, the HE sounding NDP or the EHT sounding NDP being punctured.

Abstract: Disclosed herein is a method by wireless device functioning as an access point (AP) in a wireless network for allocating an enhanced restricted access window (RAW) for low latency transmission. The method includes generating a beacon frame that includes information for allocating a RAW that includes one or more RAW slots that each includes a LLT contention period and a non-LLT contention period and wirelessly transmitting the beacon frame to allocate the RAW.

Abstract: A method provides for reducing interlink interference between an access point (AP) multi-link device (MLD) having a simultaneous transmit and receive (STR) link set and a non-AP MLD with a non-STR link set. The method includes transmitting data, by the AP MLD, to the non-AP MLD on a first link, simultaneously receiving data, by the AP MLD from the non-AP MLD, on a second link, and aligning, by the AP MLD, an end time of transmitted physical layer protocol data units (PPDUs) using padding in response to concurrently transmitting another PPDU, by the non-AP MLD, on a link that is part of the non-STR link set.

Abstract: A method performed by a wireless device functioning as an access point (AP) in a wireless network to allow low latency transmission to the AP. The method includes wirelessly transmitting a trigger frame to a first station (STA) to provide a transmission opportunity (TXOP) to the first STA, wherein the trigger frame includes information indicating that a second STA other than the first STA is allowed to wirelessly transmit a data frame to the AP during the TXOP of the first STA.

Abstract: A method is described for a wireless device, which includes determining padding for a sub-physical layer (PHY) protocol data unit (sub-PPDU) in an aggregated PPDU (APPDU). The method includes generating the sub-PPDU that includes a preamble portion and a data portion, determining a longest sub-PPDU for the APPDU to be transmitted, determining an amount and type of padding for the sub-PPDU where the sub-PPDU in not the longest sub-PPDU in the APPDU, adding padding to the sub-PPDU to align the end of the sub-PPDU with the end of the longest sub-PPUD, and transmitting the sub-PPDU through a wireless medium on a transmission channel to a receiving device as part of the APPDU.

Abstract: A method is performed by a wireless device functioning as a beamformer station (STA) in a wireless network to perform a sounding procedure. The method includes wirelessly transmitting a null data packet (NDP) announcement frame in a first frequency band, the NDP announcement frame including a sounding dialog token field where bits B0 and B1 of the sounding dialog token field are set to binary ‘1’ to indicate the NDP announcement frame should be processed as an extremely high throughput (EHT) NDP announcement frame, and wirelessly transmitting an NDP frame in a second frequency band.

Abstract: A method for transmitting a frame is provided by a device in a wireless communication network. The device compensates a carrier frequency using a value of carrier frequency offset (CFO), and transmits a frame with the compensated carrier frequency to a receiver. The value of the CFO is indicated in TXVECTOR. A method for transmitting a frame is provided by a device in a wireless communication network. The device allocates data tones for a last symbol based on a payload size, generates the last symbol having repeated waveforms and transmits a frame including at least one period waveform of the repeated waveforms in the last symbol.

Abstract: A method of transmitting a frame by a device in a wireless communication network is provided. The device generates a first symbol having a first subcarrier spacing where a symbol duration of the first symbol, excluding a guard interval, has a first length. The device generates a second symbol having a second subcarrier spacing narrower than the first subcarrier spacing wherein a symbol duration of the second symbol, excluding a guard interval, has a second length that is twice the first length.
