Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for low-latency communications in wireless networks. In some implementations, a wireless station (STA) may transmit a data session request to a root access point (AP) in a wireless network responsive to activating an application associated with latency restricted (LR) data traffic. In some aspects, the data session request may indicate one or more preferred channels to carry the LR data traffic. In some other aspects, the data session request may indicate one or more preferred times to exchange the LR data traffic. In some implementations, the root AP may establish an LR data path with the STA based on the preferred time or frequency resources indicated in the data session request. The LR data path may include time or frequency resources that are reserved for LR data traffic between the root AP and the STA.

Abstract: This disclosure provides systems, methods and apparatus for synchronous channel access control of a wireless system. In some aspects, a device may use a TWT session to communicate with a second device during one or more TWT service periods. Uplink and downlink communications may be coordinated to both be in a TWT service period to allow a device to enter a low power mode outside of the TWT service period. The TWT session, including the service periods, may be configured and managed by the device or the second device to ensure the communications associated with an XR experience between the devices (such as pose data frames or tracking frames provided as uplink data and video data frames provided as downlink data) meet latency requirements or other requirements for the XR experience. Use of TWT service periods allows other devices to use the wireless medium outside of the TWT service periods.

Abstract: Methods, systems, and devices for wireless communications are described. A station (STA) may receive a first signal including an indication of a set of frequency channels for a set of target wake time (TWT) sessions that recur according to a service interval. In some examples, the first signal may indicate a respective frequency channel of the set of frequency channels for each TWT session of the set of target wake time sessions. Each TWT session of the set of TWT sessions may have an associated service period that the STA may be in an awake state. The STA may switch, for the first TWT session, from the first frequency channel to the second frequency channel. In some examples, based on the switching, the STA may communicate a signal during a service period associated with the first TWT session over the second frequency channel.

Abstract: This disclosure provides systems, methods and apparatus for asynchronous channel access control of a wireless system. In some aspects, a device may adjust the priority of one or more PPDUs and may perform other operations to ensure control of a wireless medium at certain times while still allowing for other devices to communicate on the wireless medium. For example, the device may adjust a backoff counter or one or more EDCA parameters to ensure obtaining control of the wireless medium to transmit a first PPDU of an application file. For one or more subsequent PPDUs of the application file, the device may again adjust a backoff counter or one or more EDCA parameters to allow other devices to obtain control of the wireless medium in certain scenarios (such as a second device to provide information back to the device or to otherwise transmit using the shared wireless medium).

Abstract: Methods, systems, and devices for wireless communication are described. A station may be communicating with an access point during a first active communication period. The communication may be performed in a first power mode. The station may switch to a second power mode to transition to a sleep period. The station may determine, based on traffic indicator metric(s), whether to perform a speculative wakeup and switch to the first power mode at the end of the sleep period.

Abstract: This disclosure provides systems, methods and apparatuses for wireless communications. In some implementations, a first wireless communication device associated with a basic service set (BSS) receives a plurality of packets transmitted during a measurement window by a second wireless communication device associated with the BSS. The first wireless communication device determines a received signal strength indicator (RSSI) value of the plurality of received packets, determines a level of overlapping basic service set (OBSS) interference on the wireless medium during the measurement window, and adjusts one or more of a packet detect (PD) threshold, an OBSS PD threshold, or an energy detect (ED) threshold based on the determined RSSI value and the level of OBSS interference.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for adjusting a time period to delay entering a power save mode (leak guard) for wireless communications. In one aspect, a wireless communication device may adjust a time period to delay entering a power save mode. The time period is associated with the wireless communication device remaining awake to prevent an access point from transmitting to the wireless communication device while the wireless communication device is in the power save mode. The wireless communication device also may provide, to the AP, an indication that the wireless communication device is entering a power save mode, and the wireless communication device may enter the power save mode. Entering the power save mode is at least the adjusted time period after providing the indication to the AP.

Abstract: In a particular aspect, a method includes performing a first communication operation associated with a first frequency band using an antenna of a wireless device. The first communication operation is initiated by first communication circuitry of the wireless device. The first communication circuitry is associated with a first communication protocol. The method further includes, based on a duration of a second communication operation, performing the second communication operation associated with a second frequency band using the antenna of the wireless device. The second communication operation is initiated by second communication circuitry of the wireless device. The second communication circuitry is associated with a second communication protocol that is different than the first communication protocol. The first frequency band at least partially overlaps the second frequency band.

Abstract: Various aspects of the disclosure provide for Target Wake Time (TWT) slot scheduling in a communication network. The various aspects includes determining a number of stations in the basic service set (BSS) of an access point (AP) exceeding a minimum number of stations, determining whether to establish TWT slot scheduling for at least one or more of the stations based on one or more operational condition of the communication network, and establishing a TWT slot scheduling of the one or more of the stations if the one or more operational condition of the communication network, individually or collectively, satisfy a threshold.
