Abstract: Certain aspects of the present disclosure provide methods and apparatus that may determine operation for speed frame exchange. According to certain aspects, a method for wireless communications by an apparatus is provided. The operations may be performed by a station, for example, by an access point initiating a speed frame exchange. The method generally includes indicating, via a value of at least one bit of a field of a frame of a sequence of frames being exchanged between the apparatus and a device, whether the apparatus is initiating a subsequent exchange of a sequence of frames, and transmitting the frame to the device.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In an aspect, an apparatus may be configured to determine whether to switch to an active mode, a power save mode, or a TWT power save mode. During the TWT power save mode, the apparatus may enter an awake state during TWT service periods and may enter a doze state outside of the TWT service periods. The apparatus may transmit a message to a second wireless device based on the determination.

Abstract: Methods and apparatus for multiple user uplink are provided. In one aspect, a method for wireless communication is provided. The method includes transmitting a clear to transmit (CTX) message to two or more stations, the CTX indicating an uplink transmission opportunity, the CTX message further comprising a request that the two or more stations concurrently transmit uplink data at a specific time. The method further includes receiving a plurality of uplink data from at least two stations at the specific time.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to protecting control frames with power-related subfields. One example apparatus for wireless communications generally includes a processing system configured to generate a control frame comprising one or more power-related subfields and an integrity check value calculated based, at least in part, on the one or more power-related subfields and a transmitter configured to transmit the control frame. In aspects, a power management (PM) subfield, an end-of-service-period (EOSP) subfield, a more data (MD) subfield, or a traffic identifier (TID) subfield can be added to a group of additional authentication data (AAD) and the integrity check value is calculated based on the group of AAD.
