  • Patent number: 10952263
    Abstract: The disclosure concerns automatic pairing of a user's new device wirelessly with the user's private wireless access point. An open WLAN is used to connect a wireless pairing client (WPC) in the device with a pairing initiation server (PIS) in an ISP's network. If the open WLAN uses a “captive portal” to redirect HTTPS requests to a login page, a “pinhole” is provided so that HTTP requests addressed to the PIS are not redirected. The device stores the SSID of a suitable open WLAN and connects automatically when powered up. The WPC makes an HTTP request, including an ID for the device, to the PIS. The PIS uses the device ID to retrieve an IP address of the user's access point. The PIS then sends instruction to WPS Pairing Initiator Clients, the device and the access point to initiate a Wi-Fi Protected Setup PBC procedure.

  • Patent number: 10945162
    Abstract: A user equipment (UE) device is scheduled to transmit an uplink data transmission to its serving base station. The uplink data transmission includes a special subframe that has a different subframe structure than a subframe structure used by at least one other UE device being served by the serving base station. For example, the special subframe includes a blanked portion of the first symbol of the special subframe and a higher Reference Signal symbol density when compared to the subframe structure used by other UE devices. A target base station receives and decodes the uplink data transmission, utilizing the features of the special subframe to acquire and estimate the uplink channel between the UE device and the target base station. After decoding the uplink data transmission, the UE device is handed over from the serving base station to the target base station.

  • Patent number: 10912120
    Abstract: Embodiments of the present disclosure provide a data channel sending method. In the method, a base station starts a clear channel assessment (CCA) on a data channel for a to-be-sent data channel. If the CCA on the data channel succeeds, the base station sends the data channel in a first subframe within a time window, where the data channel performs rate matching based on a reference signal (RS). The RS includes a first RS or a second RS. The first RS occupies continuous OFDM symbols in a subframe, and the second RS occupies discontinuous OFDM symbols in a subframe. The time window is a preset time window used to send the first RS, and the first RS is used by a user equipment (UE) to perform cell identification and/or a radio resource management (RRM) measurement on a cell served by the base station.
