Abstract: A method, apparatus, and computer-readable medium are provided that improve power management for devices communicating via Bluetooth (BT) over Internet Protocol (BTOIP). The apparatus for wireless communication for a first device receives a first set of packets from a second device during a time period associated with a training phase for the first device. The apparatus determines an arrival time of a first packet of the first set of packets. The apparatus determines, based on the arrival time and a wakeup time interval, a wakeup time for the first device. The apparatus causes, based on the wakeup time for the first device and one or more attributes associated with the first set of packets, a shutdown of the first device.

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: An AP obtains service-level agreement (SLA) parameters indicating at least a delay bound for each of a plurality of traffic flows. The AP receives first packets of a first traffic flow, and delays their transmission for a delay period based on the data carried in the first packets being less than a first threshold. During the delay period, the AP receives second packets of the first traffic flow while also receiving packets of a second traffic flow, groups the second traffic flow with the first traffic flow for an MU-MIMO transmission based on the data carried in the first and second packets of the first traffic flow being greater than the first threshold and the data carried in the packets of the second traffic flow being greater than a second threshold, and transmits the first and second packets traffic flows as an MU-MIMO communication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit an indication of a media access control (MAC) address associated with an access point to a group of access points included in a network. The network node may receive single-sided round-trip-time (RTT) data associated with a user device associated with the access point, wherein the single-sided RTT data is received from each of the group of access points based at least in part on transmitting the indication of the MAC address to the group of access points. The network node may determine a location of the user device based at least in part on the single-sided RTT data. The network node may transmit an indication of the location of the user device to the access point. Numerous other aspects are described.

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 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: Certain aspects of the present disclosure provide techniques that may allow a device participating in a setup procedure to efficiently propose a range of values for a negotiated parameter. The techniques may reduce setup time, for example, allowing a responder to accept a value within the proposed range which may eliminate overhead associated with some of the back and forth message exchange of typical negotiations.
