  • Publication number: 20220303104
    Abstract: A wireless access point device is full-duplex capable and serves wireless communication for at least first and second wireless client devices. The wireless access point device sends to the first wireless client device a trigger frame that causes the first wireless client device to send an uplink transmission to the wireless access point after a first time interval. The wireless access point device waits a second time interval after the first wireless client is expected to begin sending the uplink transmission. The wireless access point device receives the uplink transmission from the first wireless client device. After the second time interval, and while receiving the uplink transmission from the first wireless client device, the wireless access point device sends to the second wireless client device a downlink transmission that overlaps at least partially in frequency and time with the uplink transmission from the first wireless client device.

  • Publication number: 20220247515
    Abstract: Preamble puncturing configuration information is encoded in a pad field, and alternatively or additionally, in a Service Field, depending on a transmission bandwidth of a Physical Layer Convergence Protocol (PLCP) Protocol Data Unit (PPDU). Some implementations also encode one or more parity bits in the pad field or Service field. The PPDU including the preamble puncturing configuration information encodes, in various embodiments, a request to send frame, a clear to send frame, a power save poll frame, or a contention free end frame.

  • Publication number: 20220150724
    Abstract: A method is provided in which an AP of a MLD AP device may decide to include all out-of-link BSS parameters updates in a beacon frame (beacon). A flag is included in the beacon frame to indicate that all updates are included in the beacon frame and thus the client device that receives the beacon frame should not send probe request frames (probe requests) to obtain these updates. Thus, a non-AP MLD that receives a beacon frame with the above indication and that has all critical BSS parameters corresponding to the Change Sequence Number (CSN) that preceded the updates indicated by the AP, should not send probe requests to obtain the updated parameters. The number of bits to assign to the complete BSS Update Report Indication flag may vary depending on the number of updates to be reported.

  • Patent number: 11323217
    Abstract: Presented herein is a tone plan that can accommodate multiple bandwidth options. This tone plan may be designed around a fundamental tile, such as 20 MHz tile, that is replicated to 40 and 80 MHz (and 160 MHz and beyond). For wider bandwidths, the otherwise-unused guard tones between the 20 MHz tiles are filled by a new resource unit and DC tones. There are DC tones placed to support any client, for all defined and plausible future values of its current operating bandwidth and center frequency (i.e. any 20 MHz, any 40 MHz, any 80 MHz, 160 MHz and 80+80 MHz, 320, 160+80 etc.), as well as plausible future preamble puncturing cases.

  • Patent number: 11252740
    Abstract: A first wireless access point uses a first radio access technology in a heterogeneous wireless network. The heterogeneous wireless network includes the first wireless access point and a second wireless access point using a second radio access technology. The first wireless access point determines one or more performance characteristics of traffic management and traffic between a first client device and the first wireless access point using the first radio access technology and the second wireless access point using the second radio access technology. The first wireless device (access point or some other network device) calculates one or more traffic indicators based on these performance characteristics. The first wireless device further communicates at least one of the one or more traffic indicators to the second wireless access point. The communicated traffic indicators are for use by the second wireless access point to schedule radio resources of the second RAT.

  • Publication number: 20220008244
    Abstract: Provided is a soft flexible oral appliance having protuberances that mimic naturally occurring dental Tori. An upper, palatial appliance and a lower, mandibular appliance may be used in conjunction or separately to alleviate a variety of disorders, improve facial tone, and increase physical performance. The appliances are lightweight, thin, and do not prohibit normal speech patterns when in use. Small protuberances are strategically molded along key surfaces of each appliance to stimulate nerves in the tongue and affect forward protrusion. Forward positioning of the tongue dilates the airways of the throat improving breathing while the use is sleeping, playing sports, or talking. It also reduces bruxing or grinding of the teeth. A method is further provided, for adding protuberances to other types of oral appliances, thereby conferring some of the benefits listed above on appliances originally intended for other dental uses.

  • Publication number: 20210321473
    Abstract: A method is performed at a first multilink device configured to communicate wirelessly with a first radio and a second radio of a second multilink device. The method includes accessing a set of parameters for a known mathematical model that establishes a frequency separation to be imposed between transmission from the first radio and reception at the second radio in order to achieve a predetermined reception performance at the second radio when the transmission and the reception are simultaneous. The method further includes, using the known mathematical model, computing the frequency separation based on the set of parameters.

  • Publication number: 20210226989
    Abstract: A management entity obtains from a first wireless access point a Basic Service Set (BSS) color collision event detected by the first wireless access point. The first wireless access point uses a first BSS color. A color collision event occurs when the first wireless access point receives from a device in a BSS of a different physical wireless access point a frame or PHY Protocol Data Unit (PPDU) that includes the first BSS color. The management entity obtains from the first wireless access point an indication whether the color collision event has been detected for longer than a predetermined duration. When the color collision event has been detected for longer than the predetermined duration, the management computes a probability of the color collision event. The management entity determines whether the color collision event is malicious or benign, and determines whether to maintain the first BSS color.
