1. A data transmission method, comprising:
determining, by a terminal device, a first frequency band, wherein a bandwidth of the first frequency band is greater than a maximum channel bandwidth supported by the terminal device;
receiving, by the terminal device, first information from a network device, wherein the first information indicates a first transmission frequency band, a bandwidth of the first transmission frequency band is smaller than or equal to the maximum channel bandwidth supported by the terminal device, and the first transmission frequency band is used by the terminal device to transmit traffic data;
receiving, by the terminal device, third information from the network device, wherein the third information indicates a second frequency band;
determining, by the terminal device, the first transmission frequency band based on the first information, wherein the first frequency band comprises the first transmission frequency band;
determining, by the terminal device, the second frequency band based on the third information, wherein the second frequency band is comprised in the first frequency band, a bandwidth of the second frequency band is smaller than or equal to the maximum channel bandwidth supported by the terminal device, and the first transmission frequency band is a part or all of the second frequency band; and
transmitting, by the terminal device, traffic data to the network device in the first transmission frequency band.
