An embodiment is method performed by a wireless device to allow preemption in a wireless network. The method includes wirelessly transmitting a first preemption physical layer protocol data unit (PPDU) that includes a complete preamble followed by one or more subsequent preemption PPDUs that each include a reduced preamble, wherein the complete preamble includes one or more preamble fields that are omitted in the reduced preamble, wherein the first PPDU and the one or more subsequent preemption PPDUs are transmitted with a predefined interframe space interval between PPDU transmissions during which preemption is allowed.

Physical layer protocol data unit (PPDU) format for reducing preamble overhead of preemption PPDUs

A method performed by a wireless device operating in a wireless network, wherein the wireless device includes a main radio and a wake-up receiver. The method includes detecting, by a first component of the wake-up receiver, a wake-up receiver preamble in a wireless transmission received by the wireless device and waking up a second component of the wake-up receiver in response to detecting the wake-up receiver preamble.

Method and frame structure for ultra-low power receivers based on IEEE 802.11AH

A method by a wireless device to extend communication range when operating in a 6 Gigahertz (GHz) band of a wireless network is described. The method includes generating a physical layer protocol data unit (PPDU) that includes a preamble portion and a data portion that includes first data and transmitting the PPDU through a wireless medium on a transmission channel that is subdivided into a plurality of resource units (RUs), wherein the first data is duplicated in the data portion in a frequency domain in units of RUs.

Extending communication range of wireless devices operating in a 6 gigahertz band

A method is described, which includes receiving, by a wireless station from a first access point, an overlapping basic service set (OBSS) status report request, which requests information from the station regarding a set of neighboring access points; transmitting, by the wireless station to the first access point, an OBSS status report that indicates path-loss characteristics of channels between the set of neighboring access points and the wireless station; receiving, by the wireless station from the first access point, an access point cooperation null data packet announcement frame, which indicates a cooperative transmission between the first access point and the second access point to the wireless station; receiving, by the wireless station from the first access point, a first null data packet and a second null data packet from the second access point, wherein the first and second null data packets are transmitted as part of the cooperative transmission.

Overlapping basic service set status indication for an access point cooperative transmission

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 Band Bof 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.
