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 only a first set of stations in the wireless network or the first set of stations and a second set of stations in the wireless network and transmitting the frame to (1) all stations in the first set of stations when the type bit indicates that the trigger frame is scheduling the uplink transmission for the first set of stations and (2) all stations in the second set of stations when the type bit indicates that the trigger frame is scheduling the uplink transmission for the first set of stations and the second set of stations.

Abstract: A method by a wireless device functioning as a beamformer station in a wireless network to perform a sounding procedure. The method includes generating a NDPA frame, wherein the NDPA frame includes a sounding dialog token field, wherein bit B0 of the sounding dialog token field is set to binary ‘1’ and bit B1 of the sounding dialog token field is set to binary ‘1’ to indicate that the NDPA frame is an extremely high throughput (EHT) NDPA frame and wirelessly transmitting the NDPA frame to one or more beamformee stations. The NDPA frame may include an indication of whether a beamformee station should acknowledge the NDP announcement frame or not. The NDPA frame may be transmitted in a first frequency band, while a beamformed data frame is transmitted in a second frequency band that is a higher frequency band than the first frequency band.

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. The device transmits a frame including the first symbol and the second symbol.

Abstract: An embodiment is a method performed by a wireless device to provide header protection for a physical layer protocol data unit (PPDU). The method includes generating a hash value of header information of the PPDU by applying a hash function to the header information of the PPDU, including the hash value in an encrypted payload portion of the PPDU, and transmitting the PPDU with the hash value included in the encrypted portion of the PPDU. An embodiment is a method performed by a wireless device to verify the integrity of header information of a received PPDU. The method includes extracting header information of the PPDU, extracting a first hash value included in an encrypted payload portion of the PPDU, generating a second hash value by applying a hash function to the extracted header information, and discarding the PPDU if the second hash value does not match the first hash value.

Abstract: Coordinated spatial reuse and frequency utilization techniques in overlapping basic service set environments for IEEE 802.11be and beyond. The techniques involve transmit power and frequency allocation methods designed for coordinated spatial reuse between multiple access points, considering interference from stations and access points, as well as occupied bandwidth. In one embodiment, an access point generates a trigger frame with punctured bandwidth or good subchannel information to coordinate spatial reuse, enabling a station to transmit an uplink data packet using specified parameters. In another embodiment, a station receives a trigger frame with punctured bandwidth information and transmits an uplink data packet excluding the puncture portion to avoid interference. The techniques allow transmissions in multiple basic service sets to coexist without harmful interference, improving throughput and frequency utilization in dense wireless networks. Although primarily described in the context of IEEE 802.11, the techniques can be applied to other wireless networks.
