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.
