  • Patent number: 10262230
    Abstract: A two-dimensional (2D) image and a three-dimensional (3D) of an environment may be captured. Upon identifying a location and/or contour of an object from the 3D image, the object from the 3D image may be mapped onto the 2D image. The object, including its location and contour, may be identified from the 2D image. Based at least partly on a comparison between the object from the 3D image and the object from the 2D image, a disparity may be calculated. The location and contour of the object may be determined when it is determined that the disparity is less than or equal to a predetermined threshold. Otherwise, the object from the 3D image may be remapped onto the 2D image.

  • Patent number: 10237797
    Abstract: A method, base station, and device perform an offload from a cellular RAN to a wireless LAN via a network selection operation to select an access network with which user terminal traffic is exchanged from the cellular RAN and the wireless LAN on the basis of parameters transmitted from a first base station to the user terminal. The parameters comprise at least one of a cellular signal strength threshold, a WLAN signal strength threshold, and a WLAN load threshold. After transmitting the parameters, the transmitted parameters are transferred from the first cellular base station to a second cellular base station, in response to the user terminal performing a handover from the first cellular base station to the second cellular base station. The transferred parameters enable the second cellular base station to determine whether there is a need for a change of configuration indicated by the transferred parameters.

    Abstract: A base station (eNB) determines device-to-device (D2D) transmission parameters for signal transmission over a D2D communication link between a first user equipment (UE) device and a second UE device. The eNB instructs the first UE device to transmit a reference signal that is received by the second UE device. The second UE device reports D2D channel characteristic information indicative of the received reference signal. Based on the D2D channel characteristic information, the base station determines the D2D transmission parameters and provides the parameters to the first UE device.

  • Publication number: 20190028232
    Abstract: An origination device (e.g., a base station) encodes first and second data packets according to a first set of encoding parameters corresponding to channel conditions associated with a first communication link between a signal forwarding device and a destination device. The resulting first and second single-encoded data packets contain the same data. The origination device combines the first and second single-encoded data packets to generate a single-encoded data block. The origination device encodes the single-encoded data block, according to a second set of encoding parameters corresponding to channel conditions associated with a second communication link between the origination device and the signal forwarding device, to generate a dual-encoded data block. The dual-encoded data block is transmitted to the signal forwarding device.
