Abstract
This application provides a data transmission method and a data transmission apparatus, which can establish a radio bearer for a data plane based on a new wireless network architecture (i.e., a network architecture in which a control plane and a user plane are separated) to implement data transmission. The method includes: a terminal device sends selection information to a control plane access network device, where the selection information indicates a target user plane access network device, which is determined from at least one user plane access network device based on system information and a user plane access network device selection rule. The terminal device receives first timing advance information and first radio bearer configuration information from the control plane access network device, and performs data transmission with the target user plane access network device based on the first timing advance information and the first radio bearer configuration information.
