Abstract: Methods, apparatuses, and computer readable media for a common preamble for wireless local-area networks (WLANs). An apparatus of an access point (AP) or station (STA) comprising processing circuitry configured to encode an AP trigger frame that includes a resource allocation for other APs to transmit trigger frames to perform an uplink or downlink multi-user transmission with stations (STAs). The resource allocation includes information so that the transmissions are coordinated at the physical level to lessen interference among the APs and the stations. The processing is configured to encode a trigger frame for multi-AP request-to-send (RTS), the multi-AP trigger frame comprising for each of a plurality of APs, the trigger frame indicating that each of a plurality of APs are to transmit a physical (PHY) protocol data unit (PPDU) comprising a request-to-send (RTS) or multi-user (MU) RTS (MU-RTS).

Abstract: 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.

Abstract: Methods and apparatus to handle enhanced distributed channel access parameters are disclosed. An example apparatus includes a frame generator to generate a data frame instructing a station to operate using a multi-user enhanced distributed channel access (MU EDCA); a communication scheduler to instruct radio architecture to transmit the data frame to the station; the frame generator to generate a buffer status request requesting a buffer status of the station; and the communication scheduler to: instruct radio architecture to transmit the buffer status request to the station; and when a response to the buffer status request corresponds to a non-null queue, scheduling the station to operate using EDCA.
