    Abstract: This disclosure describes methods, apparatus, and systems related to an OFDMA uplink resource allocation framework. An access point may determine a first trigger frame including one or more resource block identifications (RBIDs) associated with one or more resource units on a communication channel. The access point may assign at least one of the one or more RBIDs to at least one device of one or more devices. The access point may cause to send the first trigger frame to the least one device The access point may identify a resource request frame including at least in part a resource request indication associated with the at least one of the one or more RBIDs. The access point may assign one of the one or more resource units based at least in part on the resource request indication.

    Abstract: Methods, apparatuses, computer readable media for trigger frames for sounding in a wireless network. An apparatus of a wireless device is disclosed, which includes processing circuitry configured to: encode a null data packet (NDP) announcement (NDP-A) including an indication of stations, configure the wireless device to transmit the NDP-A, and encode a high-efficiency (HE) NDP. The processing circuitry may be further configured to configure the wireless device to transmit the HE-NDP and encode a trigger frame (TF) including feedback parameters for the stations and a resource allocation for each of the stations to transmit a feedback report to the wireless device. The feedback report is based on the feedback parameters and the HE-NDP. The processing circuitry may be further configured to configure the wireless device to transmit the trigger frame, and decode the feedback reports from the stations in accordance with the corresponding resource allocation and the feedback parameters.

    Abstract: This disclosure describes methods, apparatus, and systems related to cascaded trigger frame indication. A device may determine a beacon frame on a communication channel. The device may determine one or more trigger frames based at least in part on the beacon frame, the one or more trigger frames including at least in part a first trigger frame and a second trigger frame. The device may determine a cascade indication associated with the one or more trigger frames. The device may cause to send the beacon frame to one or more devices. The device may cause to send the first trigger frame to the one or more devices based at least in part on the beacon frame.

    Abstract: Example systems, methods, and devices for channel access in dense wireless networks are discussed. More specifically, methods may include transmitting one or more trigger frames from an access point to one or more communication stations, the one or more trigger frames comprising a plurality of components, the plurality of components indicating whether trigger frames within a beacon interval are scheduled in a periodic or aperiodic manner, and if periodic trigger frames are scheduled, then indicating a countdown to the next trigger frame, and if aperiodic trigger frames are scheduled, then indicating the time to the next trigger frame scheduled by the access point. Methods, apparatus, and systems described herein can be applied to 802.11ax or any other wireless standard.
