摘要： 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.

摘要： The embodiments provide a bandwidth scheduling method and an apparatus to resolve a problem in the prior art that a transmission delay is relatively large and user experience is relatively poor when a baseband unit and a radio remote unit are networked by using a passive optical network. The method includes: allocating, by a baseband unit, radio resources used for data transmission between N first radio frequency units and a terminal to the N first radio frequency units connected to the baseband unit, where N is an integer greater than 0; and then allocating, by the baseband unit based on the radio resources of the N first radio frequency units, bandwidth resources used for data transmission between the baseband unit and the N first radio frequency units to the N first radio frequency units.

摘要： An access network system and related devices are provided. The access network system includes at least one first access network device and at least two second access network devices are included, where the first access network device includes a first baseband unit (BBU), and the second base station includes a second baseband unit (BBU). At least one first baseband unit (BBU) and at least two second baseband units (BBUs) are connected in series to form a closed loop. The second baseband units (BBUs) are configured to determine a bandwidth requirement of the second access network devices. The first baseband unit (BBU) is configured to obtain, from a plurality of second baseband units (BBUs), bandwidth requirements of second access network devices corresponding to the second baseband units (BBUs), and determine a bandwidth available to each second access network device.

摘要： 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.
