Abstract: A first satellite obtains a parameter for determining an elevation angle for a departure service of the first satellite in a first serving cell. The first satellite sends first indication information to a terminal device, where the first indication information indicates the elevation angle for the departure service of the first satellite in the first serving cell in which the terminal device is located. The terminal device determines an elevation angle of the terminal device relative to the first satellite based on an ephemeris and location information of the terminal device. The terminal device determines the elevation angle for the departure service based on the first indication information, and compares the elevation angle for the departure service with the elevation angle of the terminal device relative to the first satellite, to determine whether to perform satellite reselection or handover.

Abstract: In one example method, a first image including M objects is obtained. For N objects in the M objects, when N is greater than or equal to 2, arrangement orders of the N objects is determined, where an arrangement order of any one of the N objects is determined based on at least one of a scene intent weight, a confidence score, or an object relationship score. The scene intent weight is used to indicate a probability that the any object is searched in a scene corresponding to the first image, the confidence score is a similarity between the any object and an image in an image library, and the object relationship score is used to indicate importance of the any object in the first image. Search results of some or all of the N objects are fed back according to the arrangement orders of the N objects.

Abstract: Embodiments of the present invention provide a data transmission method, a base station, and a user equipment (UE), wherein a primary base station configures a data transmission parameter for a secondary base station, to assist the secondary base station to perform uplink and downlink data transmission for the UE. Therefore, the primary base station and the secondary base station transmit and receive data according to the same data transmission parameter, and there is no need to perform extra processing on the data transmitted and received by the secondary base station, that is, the secondary base station can only reserve simple buffering, encapsulating, and transceiving functions, or even only reserve buffering and transceiving functions, so that a protocol design of the secondary base station is simplified, and cost of the secondary base station, especially cost of a micro base station serving as the secondary base station is reduced.
