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:
Techniques for reducing delay in scheduling traffic transmission in an overlapping basic service set (OBSS) environment by modifying backoff mechanisms are disclosed. In some examples, a device (e.g., station (STA) or access point (AP)) may decode at least a portion of a preamble of a received packet to determine whether the packet is sent by a member of an OBSS (e.g., STA or AP from a different BSS). Backoff operations are typically deferred as a result of the decoding. Aspects of the present disclosure provide a method, apparatus, and system to reduce delay in scheduling traffic transmissions by resuming the backoff operations prior to expiration of the period reserved for an OBSS packet by the network allocation vector (NAV). In other words, the device may not honor the NAV of the OBSS packet, and instead perform spatial reuse by transmitting another packet (or signal) on the same frequency channel during the NAV of the OBSS packet.

Certain aspects of the present disclosure provide an apparatus for wireless communications. The apparatus generally includes a processing system configured to generate a frame based on a compressed response frame format.
Abstract:
A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus is a first wireless device that may be configured to receive a data confirmation message from a second wireless device. The data confirmation message may indicate whether the second wireless device successfully received data transmitted to the second wireless device. The first wireless device may be configured to determine whether the second wireless device is associated with the first BSS or a second BSS different from the first BSS based on the received data confirmation message and on a MAC header of the received data confirmation message. The first wireless device may be configured to transmit in a time period to a third wireless device based on the determination of whether the second wireless device is associated with the first BSS or with the second BSS different from the first BSS.
Abstract:
Various aspects are provided related to techniques for dynamic sensitivity control. Modification and enhancements to dynamic sensitivity control operations are described that address hidden node issues and provide fairer access to wireless stations located at the edge of coverage of an access point. Aspects of these modifications and enhancements can be combined to provide different variants of the dynamic sensitivity control operations.
Abstract:
Certain aspects of the present disclosure provide methods and apparatus for using a shortened block acknowledgement (BlockAck) frame capable of acknowledging fragments. Such a shortened BlockAck frame may include a bitmap field having a shorter length than that of a basic BlockAck frame in the IEEE 802.11 standard (i.e.,
Abstract:
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an AP. The AP determines an interference metric of a BSS having a plurality of STAs. The AP is in the BSS. The interference metric indicates a degree of interference in the BSS caused by one or more hidden nodes associated with the plurality of STAs. The AP determines whether the interference metric meets a threshold. The AP transmits, to the plurality of STAs, a frame including an indicator when the interference metric meets the threshold. The indicator indicates to each of the plurality of STAs to enable a medium reserving procedure. The medium reserving procedure reserves a medium for data transmission.
Abstract:
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an access point. The access point transmits, to one or more stations, a first message indicating resource allocation and a specific time for the one or more stations to transmit uplink data based on downlink transmission of a second message. The access point transmits, to the one or more stations, the second message in the downlink transmission. The access point receives the uplink data from the one or more stations at the specific time based on the downlink transmission of the second message in accordance with the resource allocation.
