Abstract: Embodiments of this application provide a wireless communication method, apparatus, and system. The method includes: receiving, by a first entity, a first message sent by a second entity, where the first message carries configuration information of a sub-task, and the first entity and the second entity are entities in a radio access network; sending the configuration information of the sub-task to a terminal device; receiving a task execution result fed back by the terminal device; and sending the task execution result to the second entity. Because the sub-task is executed by the terminal device, a problem of a single communication link in a related technology can be avoided, to implement technical effects of communication flexibility and diversity. In addition, different sub-tasks are executed by different terminal devices, so that efficiency of completing a target task can be improved, and resources are appropriately used.

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.
