  • Patent number: 10291356
    Abstract: The disclosure relates to a method for decoding a transport block encoded with multiple codeblock segments. User equipment determines whether to decode one of a transport block cyclic redundancy check (CRC) and a codeblock segment CRC based on a speed of user equipment. In response to the speed of the user equipment being greater than a threshold, the user equipment decodes the transport block CRC and generates an acknowledgement (ACK)/non-acknowledgement (NAK). In response to the speed of the UE being less than or equal to the threshold, during a first data transmission, the user equipment decodes the codeblock segment CRC for each of the multiple codeblock segments and generates the ACK/NAK. During a second and latter data transmissions, the user equipment decodes the codeblock segment CRC for each of the multiple codeblock segments that failed in the first data transmission and generates the ACK/NAK.

  • Patent number: 10289913
    Abstract: A method includes obtaining two consecutive video frames at a global motion estimation function for execution on a processor, wherein the video frames comprise a current video frame and a previous video frame, and estimating motion between the two consecutive video frames by matching a set of feature points common to both video frames. The set of feature points is maintained by tracking a number of feature points in the current video frame, refreshing the feature points if the number of feature points falls below a refresh threshold, and replenishing the feature points if the number of feature points falls below a replenish threshold. Motion filtering may be performed by buffering a homogenous transformation of the global motion estimation, calculating a geometric mean of the buffered motions, and estimating intentional camera trajectory based on the geometric mean.
