Method and device for data transmission

A method for data transmission, comprising:

• determining, by a network side device, a correspondence between bearer types and user-plane configurations;
• configuring, by the network side device, the bearer type corresponding to a bearer;
• sending, by the network side device, bearer type indication information, wherein a bearer type identity is carried in the bearer type indication information;
• determining, by the network side device, the user-plane configuration corresponding to the bearer, according to the bearer type identity and the correspondence between the bearer types and the user-plane configurations;
• and
• performing, by the network side device, data transmission according to the determined user-plane configuration.

A device for data transmission, comprising a processor, a memory acid a transceiver, wherein

• the memory is configured to store instructions used by the processor in performing operations;
• the processor is configured to determine a correspondence between bearer types and user-plane configurations;
• the transceiver is configured to receive bearer type indication information indicated by a network side, wherein a bearer type identifier is carried in the hearer type indication information;
• the processor is further configured to determine the user-plane configuration corresponding to a bearer, according to the bearer type identifier carried in the bearer type indication information, and the correspondence between the bearer types and the user-plane configurations;
• and
• the transceiver is further configured to perform data transmission according to the determined user-plane configuration.
