Example data processing methods, network devices, and media are disclosed. One example method includes obtaining, by a first network device, N pieces of first round-trip time in a first periodicity. The first round-trip time is time consumed when the first network device and a second network device each transmit a packet once through an Xn/X2 interface. A minimum first round-trip time reference value is determined based on the N pieces of first round-trip time. The minimum first round-trip time reference value is a smallest value of the N pieces of first round-trip time. An inter-site synchronization offset value of the first periodicity is determined based on the minimum first round-trip time reference value. The inter-site synchronization offset value of the first periodicity is an inter-site synchronization offset value that exists when the first network device and the second network device transmit packets through the Xn/X2 interface.

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.

A method of pre-controlling the shapes of a continuous-casting slab head and tail for reducing the cut amount of the head and tail of the hot rolling intermediate slab. The continuous-casting slab head and tail, is cut into a shape such that an end surface of the head concaves inwards and the tail projects outwards. The head and tail of a slab is cut in a curve that is symmetric to the center line in width thereof. Arc height, i.e. a maximum value of the concave amount at the head or that of the projection amount at the tail, is controlled within 0 mm-50 mm.
