  • Publication number: 20240397399
    Abstract: A wireless device establishes a Bluetooth connection with a peripheral device based on one or more Bluetooth Specifications, and transmits one or more first Bluetooth-encoded data frames to the peripheral device over the Bluetooth connection. The wireless device initiates a first handover operation for communications with the peripheral device responsive to a link metric of the Bluetooth connection being less than a first link metric threshold. In some instances, the first handover operation includes selecting an access point (AP) of one or more candidate APs based on signal strengths of frames received from the one or more candidate APs, and switching the communications between the wireless device and the peripheral device from the Bluetooth connection to a wireless local area network (WLAN) channel associated with the selected AP. The wireless device transmits one or more second Bluetooth-encoded data frames to the peripheral device over the WLAN channel.

  • Publication number: 20240365238
    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.

  • Publication number: 20240357498
    Abstract: This disclosure describes a power save mechanism for devices in a neighbor awareness networking (NAN) network. In some aspects, a NAN device is able to enter into a power save mode during a window agreed to between the NAN device and a NAN peer device. A NAN device transmits, to a NAN peer device, an indication that the wireless communication device is to enter a power save mode. For example, the NAN device may transmit a MAC packet with a more data (MD) bit set to 0. The NAN peer device may indicate that the NAN device is allowed to enter the power save mode by transmitting a MAC packet with the MD bit set to 0, or the NAN peer device may indicate that the wireless communication device is not to enter the power save mode by transmitting a MAC packet with the MD bit set to 1.

  • Publication number: 20240147518
    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.

  • Publication number: 20240098615
    Abstract: This disclosure provides systems and methods for use of automated frequency coordination (AFC) to manage transmission power and frequencies. In some implementations, a device transmits, to a network entity, an AFC request. The device receives, from the network entity, an AFC response, the AFC response including an AFC power level indication of one or more nearest neighboring entities. The device sets a transmit power of the device based at least in part on the AFC power level indication of at least one of the one or more nearest neighboring entities, and the device transmits at the transmit power. In some instances, the device transmits a first number of AFC requests during a first instance of travelling along a path and transmits a second number of AFC requests less than the first number of AFC requests during one or more successive instances after the first instance of travelling along the path.

  • Publication number: 20240098549
    Abstract: Aspects of the present disclosure allow for improving E2E mesh throughput by applying transmission (TX) biasing on the Wi-Fi mesh backhaul. Aspects of the disclosure are directed to solutions for reducing traffic load in Wi-Fi mesh networks by applying TX biasing on the Wi-Fi mesh backhaul. Certain aspects are directed to selectively transmitting or preventing transmission of data over the first backhaul link to the first MLD based at least in part on a fronthaul airtime utilization, a first backhaul airtime utilization, or a second backhaul airtime utilization. Doing so allows a root access point or a network controller to apply TX biasing between multi-link operation links towards each repeater so that traffic load on a backhaul-link would not overly occupy the front-haul link because of common channel use by selectively transmitting or preventing transmission of data on the backhaul links.
