摘要： This disclosure describes systems, methods, and devices related to an extreme high throughput (EHT) signaling structure. A device may establish a communication channel with one or more station devices (STAs). The device may generate an extreme high throughput signal field (EHT-SIG) of a header, wherein the EHT-SIG field comprises information associated with resource allocations (RUs). The device may generate a frame comprising the header. The device may assign a first RU to a first station device. The device may assign a second RU to the first station device, wherein the first RU or the second RU is an aggregation of a 26-tome RU and a neighboring RU. The device may cause to send the frame to the first station device.

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： Methods, apparatuses, and computer readable media include an apparatus of an access point (AP) or station (STA) comprising processing circuitry configured to decode a legacy preamble of a physical layer (PHY) protocol data unit (PPDU), determine whether the legacy preamble comprises an indication that the PPDU is an extremely-high throughput (EHT) PPDU, and in response to the determination indicating the PPDU is the EHT PPDU, decode the EHT PPDU. Some embodiments determine a spatial stream resource allocation based on a row of a spatial configuration table, a row of a frequency resource unit table, a number of stations, and location of the station relative to the number of stations in user fields of an EHT-signal (SIG) field. To accommodate 16 spatial streams, some embodiments extend the length of the packet extension field, extend signaling of a number of spatial streams, and/or extend a number of EHT-SIG symbols.

摘要： Methods, computer readable media, and apparatus for determining a receive (Rx) number of spatial streams (NSS) for different bandwidths (BWs) and modulation and control schemes (MCSs) are disclosed. An apparatus is disclosed comprising processing circuitry configured to decode a supported HE-MCS and a NSS set field, the supported HE-MSC and NSS set field received from an high-efficiency (HE) station. The processing circuitry may be further configured to determine a first maximum value of N receive (Rx) SS for a MCS and a bandwidth (BW), where the first maximum value of N Rx SS is equal to a largest number of Rx SS that supports the MCS for the BW as indicated by the supported HE-MCS and NSS set field; and, determine additional maximum values based on an operating mode (OM) notification frame, and a value of an OM control (OMC) field. Signaling for BW in 6 GHz is disclosed.

摘要： This disclosure describes systems, methods, and devices related to intra-basic service set (BSS) signaling for multiple access points (APs). A device may determine one or more access points (APs), wherein the one or more APs are in a set of multiple basic service sets (BSSs) identified as intra-BSS. The device may include, in a first frame, a high-efficiency operation element comprising a bit associated with an indicator of the set of multiple BSSs. The device may include, in a second frame, an association identification (AID) value, wherein the AID value is associated with the device. The device may cause to send the first frame a first station device of one or more station devices. The device may cause to send the second frame to a second station device of the one or more station devices.

摘要： This disclosure describes systems, methods, and devices related to link aggregation between devices. A device may determine a first frequency band and a second frequency band for sending data to a second device in a multiband link aggregation session. The device may cause to send, in an initial state, a setup request frame to the second device for establishing the multiband link aggregation session. The device may receive, in a setup completion state, a setup response frame from the second device to establish the multiband link aggregation session. The device may cause to send, in an operating mode established state, the data to the second device over the first frequency band and/or the second frequency band in the multiband link aggregation session.

摘要： Embodiments of a station (STA), access point (AP) and method for rate adaption are generally described herein. The STA may receive a medium access control protocol data unit (MPDU) encoded in accordance with a first modulation and coding scheme (MCS). The STA may detect bit errors of the MPDU based on a comparison between the received MPDU and the decoded MPDU. The STA may determine an MCS reception margin parameter based at least partly on a comparison between a number of detected bit errors and a predetermined threshold of bit errors. The STA may transmit a block acknowledgement (BA) frame that includes the MCS reception margin parameter. The MCS reception margin parameter may enable a rate adaptation, from the first MCS to a second MCS for a subsequent MPDU for the STA.
