Abstract: An in-vehicle computing apparatus comprises a mainboard, a heat dissipation component, and a target printed circuit board (PCB). A system on chip (SOC) and a connection component are disposed on the target PCB. A side of the mainboard is attached to the heat dissipation component. The target PCB is located on a side of the heat dissipation component that faces away from the mainboard, and is detachably connected to the heat dissipation component by using the connection component.

Abstract: A base station includes multiple edge nodes and a central node. The edge nodes are configured to perform communication with a user equipment, and execute baseband processing and mutual conversion between baseband data and radio data, in which the multiple edge nodes belong to one or more edge node groups, and each edge node group includes at least one edge node. The central node is configured to perform communication with the multiple edge nodes, manage the multiple edge nodes, and perform resource sharing so that resources are shared by the multiple edge nodes. The base station is divided into two levels of architecture, namely, a central node and an edge node, and the central node implements resource sharing so that resources are shared by the edge nodes, so that a resource sharing degree in the base station is enhanced.
