Abstract: Example mapping methods and apparatus are described. One example method includes determining a message type of an uplink signaling message by an integrated access and backhaul node. The integrated access and backhaul node maps the uplink signaling message to a corresponding backhaul radio link control (BH RLC) based on an uplink mapping relationship from an integrated access and backhaul donor centralized unit and the message type. The uplink signaling message is sent to a parent node of the integrated access and backhaul node.

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.
