Abstract: This application provides an example timing advance update method, an example terminal, and an example base station. One example method includes receiving, by a terminal, an updated timing advance TA value and a beam cell identity of a beam cell in which the terminal is located that are sent by a base station. The example method also includes obtaining, by the terminal, corresponding TA compensation information based on the beam cell identity. The example method further includes performing, by the terminal, TA compensation in a TA update period based on the updated TA value and the TA compensation information. The example method also includes sending, by the terminal, uplink data by using a TA value obtained after TA compensation is performed.

Abstract: The present disclosure provides a hinge and a mobile terminal. The hinge includes at least two joints that are sequentially connected. Each joint includes a joint body, a rotation structure provided at a first end portion of the joint body, and a position-limit structure provided at a second end portion of the joint body. The rotation structures of any adjacent two joints are socketed with each other. The rotation structures of adjacent two joints are capable of rotating relative to each other. The adjacent two joints are opened or closed via relative reciprocating motion between the position-limit structures of the adjacent two joints. When an opening degree of the adjacent two joints reaches a preset value, the position-limit structures of the two adjacent joints stop each other.
