Abstract
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.
