    Abstract: Certain aspects of the present disclosure relate to station backoff behavior in uplink (UL) multiple user (MU) operations. Certain aspects of the present disclosure provide an apparatus for wireless communications. The apparatus generally includes a processing system configured to generate an unsolicited single user (SU) frame for transmission to an access point (AP) while the apparatus is configured to communicate with the AP via MU transmissions and a transmit interface configured to output the unsolicited SU frame for transmission. Certain aspects of the present disclosure provide another apparatus for wireless communications. The apparatus generally includes a processing system configured to contend for access to a medium by generating a first frame to trigger MU transmissions from a plurality of apparatuses and a transmit interface configured to output the first frame for transmission.

    Abstract: Methods and apparatus for managing reuse of a wireless medium are provided. One method of managing reuse of a wireless medium includes determining, at an access point, whether to allow reuse of the wireless medium by one or more stations in a basic service set (BSS). The method further includes transmitting, upon determining to allow reuse, an indication that reuse of the wireless medium can be permitted for stations meeting a criteria. The method further includes determining one or more reuse parameters. The method further includes transmitting the one or more reuse parameters.

    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: Methods, devices, and computer program products for traffic information signaling in a wireless communications network are disclosed. In one aspect, a method of wireless communication network is disclosed. The method includes selecting, from a variable number of control fields, one or more control fields for inclusion in a frame. The method further includes generating the frame comprising the selected number of control fields, each control field comprising an end of control field, the end of control field storing an indicator indicative of an end of the selected number of control fields or a presence of another control field in the frame. The method further includes transmitting the frame.

    Abstract: The present disclosure provides techniques for configuring the utilization of request-to-send/clear-to-send (RTS/CTS) protocol procedures based on varying conditions at the STA. For example, an AP may identify one or more conditions, when satisfied, may trigger the STA to either enable or disable uplink (UL) transmissions associated with a RTS/CTS protocol procedure. In some aspects, an AP may determine a transmit opportunity (TXOP) threshold for an STA and may determine whether to broadcast a message having the TXOP threshold to multiple STAs including the STA or unicast the message to the STA. An STA may receive a message from an AP having a TXOP threshold and may replace, based on an indication in the received message, a current TXOP threshold in the STA with the TXOP threshold in the received message. The STA may transmit an UL RTS frame in response to a determination that a planned TXOP duration satisfies the TXOP threshold.
