摘要： In a communication system, a first central unit (CU) of a first donor node determines a first mapping that comprises a route mapping or a bearer mapping. The route mapping is between the downlink data and a downlink transmission path. The bearer mapping is between the downlink data and a downlink transmission bearer. The downlink transmission path includes a transmission path between the first CU and a target node of the downlink data through a second DU of a second donor node. The downlink transmission bearer includes a RLC channel between the second DU and a next-hop node of the second DU. The first CU then sends the first mapping to a second CU of the second donor node, and sends downlink data to the second DU of the second donor node.

摘要： Embodiments of this application disclose a logical channel (LCH) configuration method. In the method, a first data radio bearer (DRB) of a terminal corresponds to a first LCH, and the first LCH is for transmitting packet data convergence protocol (PDCP) data corresponding to a source donor node. The method includes: A first relay node generates configuration information of a second LCH corresponding to the first DRB, where the second LCH is for transmitting PDCP data corresponding to a target donor node; and the first relay node sends the configuration information of the second LCH to the terminal. The source donor node and the target donor node are respectively a source donor node and a target donor node during first relay node handover or second relay node handover. A second relay node is a relay node on a link between the first relay node and the source donor node.
