Abstract: A data transmission method and a communication apparatus are provided. The method includes: receiving a first identifier from a core network element, where the first identifier indicates that a first quality of service QoS data flow and a second QoS data flow belong to a first data unit; based on the first identifier and a first synchronization time parameter, mapping the first QoS data flow and the second QoS data flow respectively to a first access network resource and a second access network resource and sending the first QoS data flow and the second QoS data flow to a terminal device, where the first synchronization time parameter indicates a maximum interval between a moment at which sending of the first QoS data flow is completed and a moment at which sending of the second QoS data flow is completed.
