  • 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: 20200015043
    Abstract: This disclosure provide systems, devices, apparatus and methods, including computer programs encoded on storage media, for providing service connectivity to a service of a service provider via a wireless local area network (WLAN). Several service connectivity techniques are described. In some implementations, a first wireless device may establish a communication link with the AP to access the service. In some implementations, the first wireless device may be an internet of things (IoT) device, and may be a headless IoT device. The communication link may be established without the wireless device joining a Basic Service Set (BSS) of an access point (AP). The service connectivity may be implemented using broadcast services between an AP and the wireless device. The broadcast services may be used for uplink broadcast traffic from the wireless device to a service provider via the AP. The service connectivity techniques may support onboarding and security features.

  • Publication number: 20160183113
    Abstract: Mobile devices implement a ranging mechanism that includes a lead responder receiving ranging measurement requests from two different initiators in the same DW cycle. At the beginning of the DW cycle the lead responder broadcasts and/or publishes a channel availability map that includes a list of slots and channels in which to respond to the ranging measurement requests based on a number of ranging operations supported in each slot within the DW cycle and based on an autonomously determined response sequence. If the lead responder responds to all ranging requests by all initiators in a DW cycle, secondary responders can perform ranging in the same or subsequent DW cycles. Upon exhausting all initiators paired with the lead responder, a secondary responder becomes the “active” responder that is chosen based on a prioritization scheme that is universal among the group of devices in the ranging operation.

  • Patent number: 9037763
    Abstract: Techniques are described for establishing a Wireless Serial Bus (WSB) service to transport data using a Media Agnostic Universal Serial Bus (MAUSB) protocol according to a selected transport mode in a WSB session of the WSB service. The MAUSB protocol may be deployed either over an Internet Protocol (IP) stack or directly over a Media Access Control (MAC) layer. According to the techniques, the wireless service advertiser and the wireless service seeker negotiate the transport mode for the MAUSB protocol in each WSB session of the WSB service. During a service discovery process, the wireless service advertiser identifies one or more supported transport modes for the MAUSB protocol in service information for the WSB service. During a P2P connection setup and a WSB session setup, the wireless service seeker indicates a selected one of the supported transport modes for the MAUSB protocol in session information for the WSB session.
