摘要： Methods, computer readable media, and wireless apparatuses are disclosed. The apparatuses including processing circuitry configured to: associate with a master station, decode a frame, where the frame comprises a first duration and a transmitter address and determine that the frame is an intra basic service set (Intra-BSS), an inter (Inter-BSS), or an unclassified frame, where the unclassified frame is the Intra-BSS frame or the Inter-BSS frame. The processing circuitry may be further configured to set an Intra-BSS network allocation vector (NAV) to the first duration if the first duration is longer than a current duration of the Intra-BSS NAV and the frame is determined to be the intra-BSS frame and set the second NAV to the first duration if the first duration is longer than a current duration of the second NAV and the frame is determined to be the inter-BSS frame or the unclassified frame.

摘要： An access point (AP) station (STA) (AP STA) may be configured to operate as a multi-AP controller in a multi-AP network. A multi-AP group formation message is encoded for transmission to other APs in the multi-AP network. The multi-AP group formation message is encoded to notify the APs of the formation of an extremely-high throughput (EHT) multi-AP group, to designate whether an AP is a member of an EHT multi-AP group, and whether an AP can take the role of a coordinator AP or coordinated AP within the EHT multi-AP group. For multi-AP joint processing, the AP STA is further configured to encode an AP trigger frame for transmission to the APs in the multi-AP network. The AP trigger frame is to trigger physical layer (PHY) and medium-access control layer (MAC) parameter synchronization. The AP trigger frame is to trigger transmission of aggregated MAC protocol data units (A-MPDUs) by the APs that include MAC parameters and PHY parameters.

摘要： This disclosure describes systems, methods, and devices related to multi-user uplink channel sounding. A device may determine a channel sounding sequence with one or more access points (APs), wherein the channel sounding sequence comprises a null data packet announcement (NDPA) communicated with at least one of the one or more APs. The device may determine a first group of station devices (STAs) associated with a first basic service set (BSS). The device may cause to send a trigger frame to the first group of STAs to solicit an uplink NDP from each STA of the first group of STAs. The device may identify a first uplink NDP received from a first STA of the first group of STAs. The device may identify a second uplink NDP received from a second STA of a second group of STAs.

摘要： Disclosed in some examples are devices (e.g., APs, STAs, and the like), methods, and machine readable mediums which provide for proper channel estimation and frame reception in Uplink MU-MIMO systems by changing the way transmission parameters from the VHT-SIG-A are communicated to the recipients in the preamble. The transmission parameters contained in the VHT-SIG-A field may be communicated to the STAs in advance of the MU-MIMO transmissions. In other examples the transmission parameters contained in the VHT-SIG-A field may be moved to locations in the preamble that come after the VHT-STF and VHT-LTF so that the transmission parameters may be decoded.

摘要： An extremely high-throughput (EHT) station (STA) may encode an EHT PPDU for transmission on a plurality of subchannels. The EHT STA may determine a spectral mask to apply to the EHT PPDU prior to transmission of the EHT PPDU. When preamble puncturing is performed, the EHT STA may apply an overall spectral mask to the EHT PPDU prior to transmission. The overall spectral mask may be based on an interim spectral mask and a preamble-puncture spectral mask. The subchannels may be in a 6 GHz band and the EHT STA may determine if preamble puncturing is to be performed for one or more of the subchannels based on a presence of incumbents in the one or more of the subchannels, although the scope of the embodiments is not limited in this respect.
