  • Patent number: 10194375
    Abstract: Network signaling loads are controlled in a wireless network by monitoring traffic patterns at an access point and determining that the access point is a high turnover access point. A high turnover access point is determined based on an average time devices spend in a coverage area of the access point being below a threshold level. Beacon and/or probe response messages are generated that identify the access point as a high turnover access point. In addition, a turnover activity value may be generated for the access point and included in the beacon and/or response messages. A mobile device may determine whether to authenticate and associate with the access point based on the turnover activity value.

  • Patent number: 10178701
    Abstract: Embodiments are provided herein for determining a synchronizing master for device-to-device (D2D) communication in a cellular network environment. In an embodiment, a user equipment (UE) receives a discovery signal comprising a timing reference, and determines a transmitter of the discovery signal. In accordance with the determination of the transmitter of the discovery signal, the UE performs one of synchronizing to the timing reference in the discovery signal and transmitting a second discovery signal. The UE performs the synchronizing to the timing reference if the transmitter of the discovery is a cellular network. Alternatively, the UE transmits the second discovery signal upon determining that the transmitter of the discovery signal is a second UE that is out of coverage of a cellular network.

  • Patent number: 10129819
    Abstract: Mobile stations can query independent basic service set (BSS) parameters of a group of Access Points (APs) by setting a Pre-Association Message Exchange BSSID Independent (PAME-BI) bit during Wi-Fi discovery. The PAME-BI bit may be included in a Generic Advertisement Service (GAS) request to indicate that an Access Network Query Protocol (ANQP) request carried by the GAS request is querying both independent and dependent BSS parameters. In some embodiments, the PAME-BI bit is included as a field in the ANQP query, rather than the GAS request message.

  • Publication number: 20180234150
    Abstract: A method for providing user equipment access to millimeter wave stations through a microwave station includes receiving an indication of millimeter wave stations operating within a microwave coverage area of a microwave station. In a microwave band, information associated with the millimeter wave stations is broadcasted to user equipment in the microwave coverage area. A request is sent to the millimeter wave stations to transmit configuration signals over a microwave band. An instruction is transmitted over the microwave band to the user equipment to perform proximity measurements of the configuration signals. According to the proximity measurements, a request is sent to a particular millimeter wave station to transmit beamforming signals over a millimeter wave band. An instruction is transmitted over the microwave band to the user equipment to perform beamforming measurements of the beamforming signals. According to the beamforming measurements, the user equipment is switched to millimeter wave operation.

  • Patent number: 10034058
    Abstract: A method and apparatus for distributing live video to multiple client devices is provided herein. In particular, a router is provided that acts on behalf of all client devices in its network. The router serves multiple groups of client devices with each group being formed by client devices having similar bandwidth requirements. The router then requests and receives video chunks from a network. The router then redistributes the video chunks to the multiple client devices using a multicast transmission. In particular, to minimize the demands on the core network, the router sets up a separate multicast to each group. Live video, of the appropriate quality is then multicast to each group.

  • Publication number: 20180184471
    Abstract: Embodiments are provided for identifying transitory WiFi users and providing a differential treatment of such users in terms of delaying associating steps between user stations (STAs) and an access point (AP). A transitory user refers to a user or user device that connects to a WiFi AP but does not run applications that require association or assigning IP addresses, such as short-term or temporary connected WiFi users that are on the move. In an embodiment, a STA connects to an AP. Upon the STA indicating its transitory behavior to the AP or the AP detecting criteria of transitory behavior of the STA, the STA obtains a delay time value from the AP. The STA then delays sending an association request to the AP, or alternatively, the AP delays handling the association request from the STA in accordance with the delay time value.

  • Publication number: 20180139768
    Abstract: The hidden node problem can be avoided by scheduling stations in different sectors to perform transmissions during different time periods. Sectorized scheduling can be communicated to stations through transmission of beamformed beacon signals at the beginning of respective time periods. For instance, a first beamformed beacon signal may be transmitted to stations in a first sector at the beginning of a first time period, while a second beamformed beacon signal may be transmitted to stations in a second sector at the beginning of a second time period.

  • Publication number: 20180123751
    Abstract: The disclosure relates to technology for assisting a wireless a communication device to acquire access to a millimeter-wave access point (mmW AP). In some embodiments, an angular direction from a mobile wireless communication device to the mmW AP is determined. In some embodiments, the mobile wireless communication device receives information from a wireless network that helps the mobile wireless communication device determine the angular direction. In some embodiments, the signals between wireless network and mobile wireless communication device are below 6 GHz. In some embodiments, the wireless network provides the mobile wireless communication device with the angular direction. Therefore, the mobile wireless communication device is able to configure an antenna to receive and/or transmit a beam in a direction of the mmW AP. The mobile wireless communication may do so during a process of gaining access to the mmW AP.

  • Patent number: 9907014
    Abstract: Wireless fidelity (Wi-Fi) access points (APs) can advertise their support of both OMA-DM and SOAP-XML protocols by including protocol capability information in a broadcast or probe response message. The protocol capability information can include an OSU method list subfield that indicates that the Wi-Fi AP supports both OMA-DM and SOAP-XML protocols. The broadcast message may be an Access Network Query Protocol (ANQP) message, a beacon message, or some other generic advertisement services (GAS) message. Wi-Fi APs can also specify which WLAN type is preferred by a network operator by including a WLAN access type indication in a broadcast or probe response message. The WLAN access type indication may specify that a network operator prefers a passpoint, non-passpoint, vendor specific WLAN. The WLAN access type indication may be included in an access network discovery and selection function (ANDSF) management object (MO).

  • Publication number: 20180041319
    Abstract: A physical downlink shared channel (PDSCH) region of a subframe may include a reference signal (RS) section that includes one or more of a beam-scanning subsection, a transmit (TX) beam-tracking subsection, a receive (RX) beam-tracking subsection, and a channel state information (CSI) subsection. Reference signals in the TX beam-tracking subsection may be used to update TX analog beams. Reference signals in the RX beam-tracking subsection may be used to update RX analog beams. Reference signals in the beam-scanning subsection may be used to evaluate different combinations of TX and RX analog beams for use in a future directional data transmission. Reference signals in the CSI subsection may be transmitted over quasi-co-located (QCL) antenna ports, and may be used for purposes of channel estimation.
