Referring to fig. 2, fig. 2 is a data transmission method according to an embodiment of the present invention, the method including:
in part 201, a network side device sends configuration information to a terminal through a first carrier.
The configuration information may be sent to the terminal through a Radio Resource Control (RRC) message.
The first carrier may be a primary carrier to which the terminal is connected.
At element 202, the terminal receives the configuration information on the first carrier.
The terminal supports data transmission after aggregation of multiple carriers, where the multiple carriers include carriers with different operating mechanisms, such as an LTE carrier in an LTE system and an NR carrier in an NR system.
The multiple carriers may be multiple continuous carriers in a same frequency band, multiple discontinuous carriers in the same frequency band, or multiple discontinuous carriers in different frequency bands.
At part 203, the terminal performs data transmission on a second carrier according to the configuration information;
