  • Patent number: 11770853
    Abstract: A method implemented by a station (STA) in a Wireless Local Area Network (WLAN) to disregard a Network Allocation Vector (NAV) maintained by the STA. The method includes receiving a first frame from an Access Point (AP), determining whether the NAV maintained by the STA was previously set using a duration indicated in a second frame that (1) was received by the STA prior to receiving the first frame and (2) originated from the AP, and transmitting a third frame to the AP as an immediate response to the first frame without considering the NAV maintained by the STA when a determination is made that the NAV maintained by the STA was previously set using the duration indicated in the second frame that originated from the AP.

  • Patent number: 11659095
    Abstract: A variety of methods, systems, devices and arrangements are implemented for assessing and/or controlling call routing for Internet-based (e.g., VoIP/VioIP) calls. According to one such method, endpoint devices are used to monitor and/or assess the call-quality. The assessment is sent to a centralized server arrangement and call-routing is controlled therefrom. Endpoint devices employ a decentralized testing mechanism to further monitor and assess call quality. Aspects of call quality are analyzed and attributed to endpoint devices and/or local connections or networks to distinguish intermediate routing issues from local/endpoint issues.

  • Patent number: 11490363
    Abstract: The present disclosure describes techniques and systems for user device-initiated bandwidth requests. In some aspects, a user device determines conditions related to communicating with a base station over a wireless connection. The user device selects, based on the determined conditions, a frequency bandwidth for communicating with the base station. The user device then transmits, to the base station, a request to communicate over the selected frequency bandwidth. In some implementations, the user device may receive, in response to transmitting the request, a resource grant allocating at least a portion of the selected frequency bandwidth for communicating over the wireless connection.
