Abstract: Communication method and base stations are provided. One example includes determining, by a base station, that co-channel interference exists. For N consecutive symbols before a guard period (GP) in a special subframe in a radio frame, the base station sends a signal by using M1 middle resource blocks (RBs) of the N symbols, and reserves use of an RB other than the M1 RBs in the N symbols, where both N and M1 are positive integers.

Abstract: A trajectory planning method for an autonomous vehicle includes a lateral displacement planner that plans a preliminary traveling trajectory for an autonomous driving vehicle based on perceptual data, positioning data, and map information, where the preliminary traveling trajectory includes N road points, and each road point includes coordinate information of the road point and allowable lateral error information of the road point. A longitudinal speed planner inherits all or some of the N road points output by the lateral displacement planner and determines speed information of n road points based on traffic road condition information and the perception data to obtain a target traveling trajectory. The speed information is a drivable speed of the autonomous driving vehicle at each of the n road points. The target traveling trajectory includes the n road points, each of the n road points including the drivable speed of the autonomous driving vehicle at the road point.

Abstract: A data indexing method is disclosed. In this method, N one-dimensional indexes that correspond to N dimensions and are independent of each other are obtained according to the N dimensions, and it is determined whether address records included in the N one-dimensional indexes have an intersection set, so as to obtain data pointed to by an address record corresponding to the intersection set, where the data is used as target indexing data, thereby solving the problem that a one-dimensional indexing technology cannot meet requirements for multi-dimensional indexing combined query and multi-dimensional analysis.

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.
