Abstract: This application provides a transmission method, a terminal device, and a network device. The transmission method includes: sending, by a terminal device, a second message to a network device after receiving a first message that is sent by the network device and that is used to instruct to activate a secondary carrier cell, where the second message is used to indicate a preset time; and receiving, by the terminal device, a third message that is sent by the network device based on the preset time, where the third message is used to instruct to trigger resynchronization of the secondary carrier cell. The transmission method in this application helps quickly reduce a time for triggering resynchronization of an uplink secondary carrier cell, and improve an uplink throughput.
