Abstract: A data transmission method and apparatus are disclosed. The method includes: determining, by a source base station of a terminal in a handover process, first data and a radio air interface protocol sequence number of a data unit used to carry the first data, where the first data includes data that is not acknowledged by a terminal for correct reception during data transmission between the source base station and the terminal. The method further includes sending, by the source base station, the first data and the radio air interface protocol sequence number to a target base station; where the core network connected to the target base station is different from the core network connected to the source base station.

Abstract: This application provides a minimization of drive tests (MDT) measurement solution, which may be used to implement an MDT measurement of a network device with an architecture in which a central unit (CU) entity and a distributed unit (DU) entity are separated. A centralized unit control plane (CU-CP) determines configuration information, and sends the configuration information to a centralized unit user plane (CU-UP) of the network device. The configuration information is used to perform an MDT measurement on a measurement object. The solution in this application may be applied to a communications system, for example, may be applied to a 5th generation (5G) network.

Abstract: Various embodiments provide a resource allocation method and an apparatus. In those embodiments, a terminal device obtains a first parameter indicating a maximum service data volume to be provided by an access network device for a first service in a first time length; and determines, based on the maximum service data volume, a resource of a media access control protocol data unit MAC PDU, the resource being occupied by buffered data of the first service. In those embodiments, the terminal device determines, based on the maximum service data volume of the first service, the resource of the MAC PDU. Compared with a conventional method, the maximum service data volume of the first service is considered. This helps improve reasonableness of allocating the resource of the MAC PDU to the data of the first service.

Abstract: The embodiments of the present disclosure disclose a small data transmission method and a related device and system. The method may include: broadcasting, by a base station, a paging message, where the paging message carries UE identifiers of a plurality of to-be-paged user equipment UE and small data sent to at least one of the to-be-paged UEs, and the small data is data whose data volume is less than a preset data volume threshold. In the present disclosure, small data may be sent to to-be-paged UE while the base station pages the UE, to reduce signaling and time overheads for sending the small data and improving communication efficiency.
