Claim 9:
10. A network side device, comprising a processor, a memory, a communication interface, and one or more programs stored in the memory and configured to be executed by a processor, wherein the programs comprise instructions to:
acquire an Media Access Control Protocol Data Unit (MAC PDU) of a terminal, wherein the MAC PDU is obtained through processing a first Packet Data Convergence Protocol Protocol Data Unit (PDCP PDU) by a first Radio Link Control (RLC) layer entity and a MAC layer entity, the first PDCP PDU is associated with a first PDCP Service Data Unit (PDCP SDU) and determined by the terminal through enabling the first RLC layer entity and invoking a PDCP layer entity when detecting that a data duplication transmission function of the PDCP layer entity is activated, and the first PDCP PDU is sent by the terminal to the first RLC layer entity, a second RLC layer entity being in an enabled status,
wherein an indication is sent to the first layer entity by the PDCP layer entity when the data duplication transmission function of the PDCP layer entity is deactivated, and a second RLC SDU associated with the second PDCP PDU in the first RLC layer entity is discarded by the first RLC layer entity according to the indication, wherein the second RLC SDU is not encapsulated and processed into an RLC PDU by the first RLC layer entity.
