A method, a terminal device and a network device for transmitting data are provided. The method includes: when the data replication function of the packet data aggregation protocol PDCP layer is switched from the active state to the closed state, the first entity of the protocol data unit PDU for transmitting the PDCP layer is determined, and the PDU is sent to the network device through the first entity. When the data replication function of the PDCP layer is switched from the active state to the closed state, the terminal device can determine the RLC entity (mapped to the RLC entity on the LCG or the RLC entity on the LCG) for transmitting the PDU of the PDCP layer, and then transmit the PDU of the PDCP layer on the RLC entity mapped to the LCG, which can effectively improve the data transmission The success rate of losing.
