    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.

    Abstract: A wireless first device may receive a packet from another device from an overlapping basic service set (OBSS). A received power of the packet may be greater than a threshold for transmitting during the time of the packet. If the first device reduces its transmit power, the first device may increase the threshold. If the received power is less than the increased threshold, the first device may count down a backoff count during a transmission time or transmission opportunity of the packet. In some cases, after the transmission time or transmission opportunity, the first device may increase its transmission power. In some cases, the condition for counting down a backoff count may also include initiating or finishing the transmission during the transmission time or the transmission opportunity of the packet, or transmitting at the reduced power.

    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive a configuration message that includes overlapping basic service set (OBSS) coordination parameters. The OBSS coordination parameters may be used to select an OBSS preamble detection (PD) threshold or a transmission (TX) power, or both. For example, an OBSS coordination parameter may include an indication of an OBSS PD threshold or the TX power or a range of OBSS PD thresholds or TX powers. In some cases, the coordination parameter may include selection criteria that may be used to select the indicated OBSS PD threshold or TX power. Additionally or alternatively, a range of selection criteria may be used to select from a range of OBSS PD thresholds and TX powers. The wireless device may use the selected OBSS PD threshold or TX power to communicate with an AP or other devices.

    Abstract: A first AP in a wireless network determines that a wireless client device should re-associate from the first AP to a second AP of the wireless network. The first AP communicates an AP coordination message from the first AP to the second AP to share coordination information with the second AP. The first AP coordinates with the second AP to cause the re-association of the wireless client device in accordance with the coordination information. The first and second AP may coordinate directly to synchronize re-association activities. Re-association activities may include the use of a configuration message to the wireless client device, managing transmit power of beacon messages from the first and second APs, or forced disassociation and blocking. The first AP may maintain a record of which re-association activity was successful in causing the wireless client device to re-associate to the second AP.
