FIELD: communication technology.
SUBSTANCE: invention relates to communication technology; it can be used for duplicated transmission. In a method for configuring a duplicated transmission in the case, if a transmission mode of a split unidirectional channel is a duplicated transmission, a main network access device configures a radio link control (hereinafter – RLC) object of the split unidirectional channel in the main network access device to an unconfirmed mode (hereinafter – UM), wherein RLC objects of the split unidirectional channel are located separately in the main network access device, a secondary network access device and a terminal device. The main network access device transmits indicator information to the secondary network access device, wherein indicator information is used to indicate that the transmission mode of the split unidirectional channel is a duplicated transmission, and indicator information is used to configure the RLC object of the split unidirectional channel in the secondary network access device on UM. The main network access device also transmits indicator information to the terminal device, wherein indicator information is used for the terminal device in order to perform a duplicate transmission.
EFFECT: reduction in the loss of service data of the radio interface and reduction in transmission delay.
