Abstract: Various embodiments provide a signal transmission method and apparatus, and is applied to a multi-band communications system. Under the method, a terminal reports bandwidth capability information of a first frequency band in a plurality of frequency bands to a radio access network node. An operating band of the terminal includes the first frequency band, the bandwidth capability information of the first frequency band indicates a bandwidth capability of the terminal in the first frequency band, the bandwidth capability in the first frequency band is not less than a first threshold, and the first threshold is determined based on a maximum bandwidth capability of the terminal, the first frequency band, or a subcarrier spacing of the first frequency band. The terminal can send or receive a signal on a resource allocated by the radio access network node based on the bandwidth capability information.

Abstract: Example methods and apparatus for transmitting a signal transmission method and a device are disclosed. One method includes transmitting a signal based on a predefined transmission pattern by a communications device. The transmission pattern defines that a non-first downlink timing boundary in a downlink time domain unit is later than or earlier than a first downlink timing boundary is defined, or that an uplink timing boundary in an uplink time domain unit is earlier than or later than the first downlink timing boundary.

Abstract: Example data processing methods and apparatus are provided. One example method includes obtaining an image captured by an in-vehicle camera. A to-be-detected target in the image is determined. A feature region corresponding to the to-be-detected target in the image is further determined based on a location of the to-be-detected target in the image. A first parking state is determined based on the image and wheel speedometer information. A first homography matrix corresponding to the first parking state is determined from a prestored homography matrix set, where different parking states correspond to different homography matrices. Image information of the feature region is processed based on the first homography matrix to obtain a detection result.
