Abstract: A base station includes multiple edge nodes and a central node. The edge nodes are configured to perform communication with a user, 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.

Abstract: Embodiments of this application provide a time synchronization offset adjustment method and apparatus, a terminal, and an access layer device. The method includes: compensating, on a 1588 terminal or an access layer device based on a 1588 time offset value, for a 1588 time obtained through synchronization. This reduces an error caused by asymmetric delays on transmit and receive links, and improves precision of the 1588 time obtained through synchronization.
