Abstract: Techniques are provided for dynamic forbiddance of wireless transmissions by transmitters of one or more overlapping basic service set (OBSS) concurrent with transmissions of a transmitter in a first basic service set (BSS). A first transmitter of a first BSS may identify a transmission that is to be a protected transmission, and based on the identification may dynamically forbid one or more other transmitters of an OBSS that overlaps with the first BSS from concurrent transmissions with the protected transmission. An access point or station of an OBSS may receive an indication of the forbiddance of transmissions and may apply deferral rules to defer transmissions based on the forbiddance. One or more disincentive rules may be applied at the first transmitter to provide disincentives for forbidding OBSS reuse.

Abstract: Methods and apparatus for multiple user uplink are provided. In one aspect, a method for wireless communication is provided. The method includes receiving a trigger frame from an access point, the trigger frame being transmitted to two or more stations and indicating an uplink transmission opportunity. The trigger frame further includes a request for the two or more stations to concurrently transmit uplink data at a specific time. The method includes transmitting uplink data at the specific time to the access point concurrently with another of the two or more stations transmitting uplink data to the access point.

Abstract: Methods, systems, and devices are described for wireless communications. A network may employ additional contention based parameters to support MU transmissions and to communicate to other devices a duration that protects MU transmission. For example, a first device may transmit a first message to reserve a subband of shared spectrum. The first message may be addressed to multiple devices and may indicate a channel access deferral duration to other devices within transmission range. The non-addressed devices may refrain from accessing the channel for an indicated duration. The addressed devices that receive the first message may respond to the first message with a second message, which may also be used to reserve the channel. The second message may additionally be used to identify those devices that received the first message. The first device may generate a trigger message based on the received second messages.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In an aspect, an apparatus may be configured to transmit a first message that includes a first trigger field to a second wireless device. The first trigger field may indicate whether the first message includes a request for a trigger message to be sent by the second wireless device at a start of a TWT service period. The apparatus may be configured to receive a second message from the second wireless device. The second message may include a second trigger field based on the first message, and the second trigger field may indicate whether the second wireless device will transmit the trigger message at the start of the TWT service period.
