    Abstract: This disclosure describes techniques for transmitting Bluetooth data over a contention-based communication link (such as a P2P link). In some instances, a wireless device transmits, to a Bluetooth-enabled peripheral device over the contention-based communication link, one or more first data packets based on a set of transmission parameters. The wireless device receives, from the Bluetooth-enabled peripheral device, a buffer status report carrying feedback information indicating one or more of a quantity of data packets queued in a receive buffer of the peripheral device, a rate at which the data packets are queued in the receive buffer, or time-of-arrival (TOA) information of the data packets queued in the receive buffer. The wireless device adjusts the set of transmission parameters based on the feedback information, and transmits, to the Bluetooth-enabled peripheral device over the contention-based communication link, one or more second data packets based on the adjusted set of transmission parameters.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter may detect at least one distance between the transmitter and a receiver. The transmitter may transmit, to the receiver, information using a selected band of a wide band or a narrow band, where the selected band is based at least in part on the at least one distance. Similarly, in some aspects, a receiver may detect at least one distance between the receiver and a transmitter. The receiver may receive, from the transmitter, information using a selected band of a wide band or a narrow band, where the selected band is based at least in part on the at least one distance. Numerous other aspects are described.

    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.
