Abstract: Embodiments of the present invention describe a data transmission method, a related device, and a system. The method may include sending, by a terminal, uplink data to a network device. The uplink data is scrambled by using a scrambling sequence, and the scrambling sequence is generated based on information about a radio resource used by the terminal to send the uplink data. According to the embodiments of the present invention, it can be ensured that scrambling and descrambling on the uplink data are successfully implemented when the network device does not obtain an identifier of the terminal in a cell.

Abstract: The present disclosure provides a service indicator display method and device. The method includes: obtaining measurement values of service indicators in a building and a three-dimensional grid model of the building, where an outer surface of the model includes multiple polygons; determining, according to the measurement values of the service indicators, a measurement value that is of a service indicator and that is corresponding to a vertex location of each polygon; performing gradient rendering on each polygon according to a legend and the measurement value, to obtain spatial distribution of the service indicators; and displaying the spatial distribution in the building. A surface of a building model is divided more finely by using a polygon, and spatial location distribution of service indicators is reflected more truly by means of gradient rendering, so as to improve network optimization efficiency.

Abstract: Methods, apparatus, and computer programs stored on a computer-readable storage medium for obstacle avoidance are provided. One example method includes obtaining vehicle information, obstacle information, and a drivable area of a vehicle at a moment t, and processing the drivable area based on the vehicle information and the obstacle information to obtain a potential energy grid map. The method can include obtaining information about a center line of a lane in which the vehicle is currently located, and obtaining a parallel-line track cluster based on the information about the lane center line. The method can include calculating a cost value of each parallel-line track, and performing time-domain filtering on a parallel-line track with a minimum cost value in the parallel-line track cluster to obtain a target track at the moment t specifying a parallel line track that is used by the vehicle to avoid an obstacle.

Abstract: A cooling apparatus is provided, including a jet plate and a carrier plate provided with an accommodating groove, a coolant inlet, and a coolant outlet. The jet plate is in the accommodating groove, with nozzles provided on the jet plate in a protruding manner. A distribution cavity is between the jet plate and the carrier plate, and the distribution cavity communicates with the coolant inlet, which is for injection of cooling liquid. A collection cavity for backflow of the cooling liquid is formed in the accommodating groove, and is separated from the distribution cavity. The coolant outlet communicates with the collection cavity. The cooling liquid is distributed to the jet plate through the distribution cavity, and is sprayed to the collection cavity through the nozzles for heat exchange, and the cooling liquid obtained through heat exchange is converged in the collection cavity and flows out through the coolant outlet.
