Abstract: Methods, systems, devices, and apparatuses are described for a listen-before-talk (LBT) mechanism. A wireless node, e.g., a base station, may determine that a channel is available based on completing a clear channel assessment (CCA) procedure. The wireless node may be associated with a first operator. The wireless node may transmit a first message on the channel in a subframe based on the CCA procedure. The first message may include a header portion that precedes a data portion. The first message may be time aligned with a second message transmitted from a second wireless node that is associated with the first operator.

Abstract: A method of manipulating an image by a mobile-device includes segmenting image data corresponding to the image into a first image layer and a second image layer. The method also includes receiving a first user input at the mobile device, the first user input indicating a direction relative to the mobile device, and performing a first image editing operation on the first image layer based on the first user input. The method further includes receiving a second user input at the mobile device, the second user input indicating the direction relative to the mobile device, and performing a second image editing operation on the first image layer based on the second user input. The second image editing operation is distinct from the first image editing operation.

Abstract: A method for determining a region of an image is described. The method includes presenting an image of a scene including one or more objects. The method also includes receiving an input selecting a single point on the image corresponding to a target object. The method further includes obtaining a motion mask based on the image. The motion mask indicates a local motion section and a global motion section of the image. The method further includes determining a region in the image based on the selected point and the motion mask.

Abstract: Methods of determining a position of a mobile device in a vehicle are disclosed. An angular velocity of the vehicle, at a turning time while the vehicle is turning, may be determined according to input from an inertial sensor system of a first mobile device. A longitudinal acceleration, at the turning time, of linear acceleration along a longitudinal axis of the vehicle, may be determined according to input from the inertial sensor system. A lateral acceleration, at the turning time, of linear acceleration along a lateral axis perpendicular to the longitudinal axis, also may be determined according to input from the inertial sensor system. A first distance from the first mobile device to a rear axle of the vehicle may be calculated, based at least in part on the angular velocity, the longitudinal acceleration and the lateral acceleration.

Abstract: Techniques provided herein are directed toward virtually extending an updated set of output positions of a mobile device determined by a VIO by combining a current set of VIO output positions with one or more previous sets of VIO output positions in such a way that ensure all outputs positions among the various combined sets of output positions are consistent. The combined sets can be used for accurate position determination of the mobile device. Moreover, the position determination further may be based on GNSS measurements.

Abstract: Techniques provided herein are directed toward selecting GNSS measurements to greatly improve the position accuracy while keeping the complexity bounded. Specifically, only subset of available GNSS measurements in a window of time is selected for outlier rejection and estimation algorithms, where GNSS measurements are selected such that corresponding measurement locations are spaced with at least a minimum distance.

Abstract: Techniques provided herein are directed toward reducing inaccuracies in a fused GNSS/VIO output by comparing GNSS/VIO position candidates with an estimated position based on VIO propagation or other motion detection. If, for a given GNSS epoch, none of the position candidates are within a threshold distance of the estimated position, the estimated position is used as the determined position for the epoch. In some embodiments, least some of the GNSS measurements used in determining the position candidates may be removed for subsequent outlier rejection and position estimation.

Abstract: Methods, systems, and devices are described for techniques for downlink (DL) scheduling and uplink (UL) scheduling in a shared radio frequency (RF)spectrum band. In some aspects, a wireless communication device may receive an UL data transmission grant associated with a channel of shared RF spectrum band. The wireless communication device may perform a channel readiness procedure associated with the channel. The wireless communication device may also transmit channel readiness information based at least in part on the channel readiness procedure to a base station. The channel readiness information may be transmitted via an uplink channel of a licensed RF spectrum band different from the shared RF band. In other aspects, a base station may schedule a data transmission on one or more channels of a shared RF spectrum band. The base station may transmit a data transmission grant for the scheduled data transmission to a wireless communication device.
