Claim 14:
15. A method of transmitting data applied to a network side device, comprising:
receiving, by a master medium access control (MAC) entity and one or more secondary MAC entities of a network side device, duplicated transmission data transmitted by a user equipment (UE) through different carriers when a packet duplication mode is configured or activated for a bearer;
transmitting, by the master MAC entity and the one or more secondary MAC entities, the transmission data to different radio link control (RLC) entities through different logical channels; and
transmitting, by the RLC entities, received transmission data to a Packet Data Convergence Protocol (PDCP) entity;
wherein before the packet duplication mode is configured or activated for the bearer, the method further comprises:
receiving a UE capability sent by the UE, the UE capability carrying capability indication information indicating whether a packet duplication is supported or not;
wherein before the packet duplication mode is configured or activated for the bearer, the method further comprises:
configuring semi-statically or dynamically a mapping between the carriers and the master MAC entity and the secondary MAC entities, and transmitting the mapping to the UE;
or
configuring semi-statically or dynamically a mapping between the logical channels and the carriers, and transmitting the mapping to the UE;
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.
