    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: Methods, systems, apparatuses, and devices are described for contention resolution techniques for medium access using a spatial dimension, a frequency dimension, or a combination of the both. A wireless station may determine that an access timer associated with backoff operations has expired. The wireless station may identify a domain index associated with the frequency domain, the spatial domain, or a combination. The wireless station may access the wireless medium according to the identified domain index. The wireless station may, prior to sending other transmissions, transmit a trigger frame including information associated with the resources of the wireless medium that are reserved for communications. Other wireless stations may share the medium and use the free resources.

    Abstract: Various aspects provide for receiving identity information from a station (STA) that identifies the STA as a sensor-type STA, determining whether communication attributes of the STA correlates with communication attributes expected for a sensor-type STA, and determining that the identity information received from the STA is false when the one or more communication attributes of the STA is uncorrelated with the one or more communication attributes expected for a sensor-type STA. Additional aspects provide for initiating one or more remedial actions upon determining that the identity information is false. The communication attributes may pertain to packet size, inter-arrival time, and/or inter-arrival time variance. The remedial actions may include blocking a future communication with the STA, communicating a warning message to the STA, and/or assigning the STA to a particular access window. Communications by the STA may comply with aspects of Institute of Electrical and Electronics Engineers (IEEE) 802.11ah.

    Abstract: Certain aspects of the present disclosure relate to including deferral information in postambles and midambles. An apparatus for wireless communications may generally include a processing system configured to generate a first frame having at least one of a midamble or a postamble that provides an indication of a request for a device to defer transmitting for a duration and an interface configured to output the first frame for transmission. Another apparatus for wireless communications may generally include a processing system configured to generate a frame having at least one of a midamble or a postamble designed to allow a device, after exiting a low-power state, to perform synchronization to the frame and an interface for outputting the frame for transmission. Including midambles and postambles in a frame allow for more reliable responses and may reduce throughput losses and interference.

    Abstract: A method of adjusting a carrier sense threshold to avoid hidden nodes during wireless broadcast. The method includes monitoring a load of the peer-to-peer network before broadcasting a message from a node. The method also includes adjusting a carrier sense threshold (CST) based on the load of the peer-to-peer network to avoid broadcast message collisions due to one or more hidden nodes.
