    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.

    Abstract: Systems, methods, and devices for wireless communication are described herein. In some aspects, a method of wireless communication includes transmitting a first message for establishing a reservation of the communication medium utilizing a first combination of transmission characteristics such that the first message is readable by a plurality of wireless devices. The method may further include subsequently transmitting a plurality of messages for clearing the reservation of the communication medium, each of the plurality of messages utilizing a different combination of transmission characteristics than the first combination such that each of the plurality of messages is readable by a different subset of the plurality of wireless devices, thereby sequentially clearing access to at least one communication channel of the communication medium for each different subset of the plurality of wireless devices.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. In one implementation, an apparatus includes a processing system configured to attempt communication with a first device via a first channel, connect with a second device associated with the first device in response to a determination that communication with the first device was unsuccessful on the first channel, and receive channel information associated with the first device from the second device, wherein the channel information indicates a second channel used by the first device.
