Classification: CPC H | IPC H

Claim 0:
1. 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 prior to the transmitting, by the UE, the duplicated transmission data to the different RLC entities respectively, the method further comprises:
transmitting a UE capability to the network side, the UE capability carrying capability indication information indicating whether a packet duplication is supported or not;
wherein prior to the transmitting, by the UE, the duplicated transmission data to the different RLC entities respectively, the method further comprises:
receiving a mapping between the carriers and the master MAC entity and the one or more secondary MAC entities that is configured by the network side semi-statically or dynamically; or
receiving a mapping between the logical channels and the carriers that is configured by the network side semi-statically or dynamically;
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 packet duplication mode is not activated and the 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 packet duplication mode is not 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.
