Abstract: A method includes the following. A first communications device obtains an ith data packet, divides the ith data packet into N data blocks, performs fountain-code encoding on the N data blocks to generate K fountain-code codewords, generates K protocol data units (PDUs) based on the K fountain-code codewords, and sends the K PDUs to a second communications device; and after the first communications device receives first acknowledgement information sent by the second communications device, the first communications device stops, based on the first acknowledgement information, sending a to-be-sent PDU in the K PDUs to the second communications device.

Abstract: This application provides a data transmission method. In the method, a first access network device and a second access network device establish a data radio bearer (DRB)-based tunnel and a session-based tunnel. The second access network device sends a Packet Data Convergence Protocol (PDCP) layer data packet to the first access network device via the DRB-based tunnel; and the second access network device sends a Service Data Adaptation Protocol (SDAP) layer data packet to the first access network device via the session-based tunnel.

Abstract: A method for a handover of a mobile station performed by a source base station and a target base station. The target base station receives a handover request message, from the source base station, in which includes QoS information of the mobile device, radio bearer identifier information of the source base station, and a first mapping relationship between a flow and a radio bearer of the source base station, the target base station acknowledges with a handover acknowledgement message. Therefore resource preparation at the target base station during a handover procedure is improved.

Abstract: This application provides example communication methods and example communications apparatuses, to implement bearer mapping for user data transmission. One example method is applied to a wireless backhaul system having a first network and a second network of different RATs. The example method includes obtaining, by a first management network element in the wireless backhaul system, information about a first radio bearer of a terminal in the first network, where the information about the first radio bearer is used to indicate the first radio bearer. The first management network element can then determine a mapping relationship between the first radio bearer and a second radio bearer based on the information about the first radio bearer, where the second radio bearer is a radio bearer of the first device in the second network.
