Method of transmitting data, user equipment, network side device and computer readable storage medium

A method of transmitting data applied to a user equipment (UE), comprising:

• transmitting, by the UE, duplicated transmission data to different radio link control (RLC) entities respectively when a network side configures or activates a packet duplication mode for a bearer;
• transmitting, by one of the different RLC entities, the transmission data through one of logical channels to a master medium access control (MAC) entity and transmitting, by each of the others of the different RLC entities, the transmission data through a different one of the logical channels to a different one of one or more secondary MAC entities;
• and
• transmitting, by the master MAC entity and the one or more secondary MAC entities, the transmission data to the network side through different carriers;
• wherein both the master MAC entity and the one or more secondary MAC entities are configured to bear a logical channel corresponding to a bearer for which packet duplication mode is not configured or activated and logical channels corresponding to a bearer for which packet duplication mode is configured or activated;
• wherein when one of the one or more secondary MAC entities is released, the logical channel corresponding to the bearer for which packet duplication mode is not configured or activated that is borne on the released one of the one or more secondary MAC entities is automatically transferred to be borne on the master MAC entity.
