Abstract: Methods and apparatus are described by which a wireless station transmits information to an access point in response to a short feedback request. The response to the short feedback request is transmitted as either energy or lack thereof in one or more long training fields transmitted in a preamble of a physical layer packet. Short feedback trigger frames for requesting the short feedback are also described.

Abstract: Methods and devices are described for providing wireless stations (STAs) with two sets of enhanced distributed channel access (EDCA) parameters. Legacy EDCA parameters that are for single user (SU) operations and may be used by both high-efficiency (HE) STAs and legacy STAs without multi-user (MU) capability. MU EDCA parameters are defined to be more restrictive than legacy EDCA parameters in favoring MU operations. Embodiments are described that define sets of rules for regulating how STAs capable of both SU and MU uplink operations can use the different sets of EDCA parameters.

Abstract: A wireless communication device includes a memory, and a processing circuitry coupled to the memory. The processing circuitry is to process a wake-up radio (WUR) frame transmitted by an Access Point (AP), the WUR frame comprising a medium access control (MAC) header and a frame body, the MAC header comprising a Frame Control field, an Address field, and a Type Dependent (TD) Control field, wherein the Frame Control field comprises a Type field; determine, based on a value of the Type field, that the WUR frame is a WUR Discovery frame; determine an identifier (ID) of the AP from the WUR Discovery frame; and in response to a determination that the WUR frame is a WUR Discovery frame, cause a Primary Connectivity Radio (PCR) corresponding to the wireless communication device to communicate with the AP based on the WUR Discovery frame.

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: Embodiments of a station (STA), access point (AP) and method for aggregation of data packets are generally described herein. The AP may transmit a trigger frame (TF) to an STA that indicates an access class (AC) constraint parameter and a traffic identifier (TID) aggregation limit parameter. The STA may select a group of aggregate TIDs from which medium access control (MAC) protocol data units (MPDUs) may be aggregated into an aggregated MPDU (A-MPDU). The AC constraint parameter may indicate a recommended AC from which at least a portion of the aggregate TIDs are to be selected. The TID aggregation limit parameter may indicate a number of TIDs to be selected for the group of aggregate TIDs.

Abstract: Methods, computer readable media, and wireless apparatuses are disclosed. The apparatus comprising a memory and processing circuitry coupled to the memory. The processing circuitry is configured to: associate with a master station, decode a trigger frame or a multi-user request-to-send (MU-RTS) frame from the master station, where the trigger frame or the MU-RTS frame comprises a first duration and a transmitter address, and respond to the trigger frame or the MU-RTS frame if a network allocation vector (NAV) is not set, or if the NAV is set and a saved transmission opportunity (TXOP) holder address for the NAV is the same as the transmitter address of the MU-RTS or trigger frame and the trigger frame or MU-RTS indicates the station is to respond.

Abstract: Embodiments of a high-efficiency Wi-Fi (HEW) station, access point (AP), and method for communication in a wireless network are generally described herein. In some embodiments, the HEW AP may transmit a resource allocation message to indicate an allocation of channel resources for uplink transmissions by one or more HEW stations. The channel resources may include multiple channels, each of which may include multiple sub-channels and an extra portion of channel resources. The resource allocation message may include multiple sub-channel allocation blocks to indicate an allocation for a particular HEW station. A length of the sub-channel allocation blocks may be based on various factors, such as a number of channels included in the channel resources and a sub-carrier bandwidth.

Abstract: Embodiments of a high-efficiency Wi-Fi (HEW) station, access point (AP), and method for random access contention in a wireless network are generally described herein. In some embodiments, the HEW station may receive a beacon frame that indicates a number of trigger frames (TFs) included in a beacon interval. The beacon frame may be received from an HEW access point (AP) in channel resources that include multiple sub-channels. The HEW station may receive a random access TF that indicates a random access portion of the sub-channels that are allocated for random access contention during an uplink transmission period. The HEW station may select a candidate sub-channel from the channel resources. When the candidate sub-channel is included in the random access portion, the HEW station may transmit an association request (AR) frame on the candidate sub-channel during the uplink transmission period.

Abstract: Methods, computer readable media, and wireless apparatuses are disclosed for a TXOP duration field disable setting in a HE preamble, such as HE-SIG-A. An apparatus of a wireless device can include processing circuitry configured to decode a HE PPDU received from a second wireless device, the HE PPDU including a first TXOP duration field in a PHY portion of the HE PPDU. The processing circuitry can detect whether the TXOP duration field includes a disable flag based on bit values of the TXOP duration field. The disable flag can indicate absence of duration information in the TXOP duration field. Upon detecting the disable flag, a response HE PPDU can be encoded for transmission to the second wireless device. The response HE PPDU can include a second TXOP duration field with a disable flag within a PHY portion of the response HE PPDU.

Abstract: Methods, apparatus, and computer-readable media are described to encode, by a first station, duty cycle timing for transmission to a second station via a primary connectivity radio. A wake-up radio (WUR) receiver (WURx) is enabled to receive a transmission based upon the duty cycle timing of the WURx when the primary connectivity radio is in a doze state from a perspective of the second station. A wake-up packet, received from the second station, is decoded and received by the WURx. The WURx receives a WURx transmission when in an WURx awake state. The primary connectivity radio is enabled based upon decoding the wake-up packet.
