Abstract: A method, an apparatus, and a system for implementing data scheduling are provided. By adopting the method, the apparatus, and the system in embodiments of the present invention, a BSR is generated when uplink data that needs to be sent exists; and by using the BSR and correspondence between a logical channel and a base station, a UE can transmit the uplink data on a logical channel that corresponds to a base station, thereby avoiding a problem that data cannot be processed because a radio resource and a logical channel correspond to different base stations, so that the UE can transfer data to be uploaded to a correct base station corresponding thereto, which greatly improves efficiency of data scheduling in a mode of carrier aggregation between base stations.

Abstract: An inter-distributed-unit (distributed unit, DU) communication method and a related apparatus are provided. The method includes: A first DU receives data of a terminal from a central unit (central unit, CU). The first DU processes the data by using a media access control (media access control, MAC) entity scheduling function specific to the terminal, to obtain a physical layer transmission data stream. The first DU sends the physical layer transmission data stream to a second DU. In the method provided in this application, because a MAC entity of the first DU is used to uniformly schedule the physical layer transmission data stream, the first DU and the second DU do not need to exchange a large amount of layer 2 (layer 2, L2) parameter information, so that information transmission overheads can be reduced.

Abstract: A communication method and an apparatus are provided in embodiments of this application. When a cell served by a DU of an access network device and a neighboring cell use different timing, the DU may obtain timing configurations of a first cell and a second cell, or a RACH configuration that is of a second cell and that is based on timing of a first cell. When the method is applied to a RACH optimization scenario, the DU may determine, at same timing, RACH configurations of the two cells based on the foregoing obtained information, to accurately identify whether a RACH configuration conflict occurs between the cell and the neighboring cell, optimize the RACH configuration of the cell when the conflict occurs, and ensure a success rate and an access latency of random access performed by a terminal device.
