  • Patent number: 10713472
    Abstract: A first face region within a first image is determined. The first face region includes a location of a face within the first image. Based on the determined first face region within the first image, a predicted face region within a second image is determined. A first region of similarity within the predicted face region is determined. The first region of similarity has at least a predetermined degree of similarity to the first face region within the first image. Whether a second face region is present within the second image is determined. The location of the face within the second image is determined based on the first region of similarity, the determination of whether the second face region is present within the second image, and a face region selection rule.

  • Publication number: 20200220600
    Abstract: Channel state information (CSI) operations are disclosed with regard to elevation beamforming (EB)/full dimension (FD) multiple input, multiple output (ED/FD-MIMO) operations. With CSI processing associated with multiple CSI-reference signal (CSI-RS) resources, ambiguities may arise in determining the CSI reporting type and rank. CSI reporting type may be determined using a last reported beam selection indicator (BI) or, in the absence of a BI, may be determined according to a predefined rule. When rank and BI are reported separately and rank is absent, user equipment may determine a default reference rank for CSI reporting based on either or both of previously reported rank or BI. When rank and BI are jointly reported, encoding schemes with fixed bitwidths determined based on either CSI-RS processes or resources may be used to enhance decoding. CSI-RS antenna ports, processes, or resources may also be used in determining application of CSI processing relaxation.

  • Publication number: 20200220591
    Abstract: A base station may transmit to a device an indication of codebook subset restriction (CBSR), which includes at least a restriction on a frequency basis. The device may receive the indication of CBSR, and may transmit to the base station channel state information (CSI) according to the received indication of CBSR. The indication of CBSR may also include a restriction on a spatial basis and restrict the device from reporting the CSI based on a subset of the frequency basis in addition to the spatial basis per configuration of the base station. The indication of CBSR may include a separately configured maximum allowed amplitude of a weighting coefficient for the spatial basis and the frequency basis, where the weighting coefficient is associated with a column vector of a precoding matrix used by the base station and the device.

  • Publication number: 20200220603
    Abstract: Methods, systems, and devices for wireless communication are described. In wireless systems supporting multiple-input, multiple-output (MIMO) transmissions, devices may implement beam-forming to improve reliability of communications. A user equipment (UE) may select a set of beams, and corresponding beam indices, for communication based on reference signals received from a base station. The UE may determine values corresponding to each of the beam indices using a scalable set of tables. For example, the UE may select a subset of the tables based on the number of selected beams, and may determine the values based on these tables. In this way, the UE may efficiently store sets of tables for multiple different configurations. The UE may sum the corresponding values to obtain a combination index value, and may transmit the combination index value to the base station. The base station may determine the selected beams based on this combination index value.
