Claim 5:
6. A terminal, 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:
receive a second Packet Data Convergence Protocol Service Data Unit (PDCP SDU) via a PDCP layer entity;
when a data duplication transmission function of a PDCP layer entity is activated, encapsulate a second PDCP SDU into a second PDCP Protocol Data Unit (PDCP PDU) via the PDCP layer entity; and
send the second PDCP PDU to a first Radio Link Control (RLC) layer entity and a second RLC layer entity via the PDCP layer entity,
wherein the programs further comprise instructions to:
when the data duplication transmission function of the PDCP layer entity is deactivated, send an indication to the first RLC layer entity via the PDCP layer entity; and
receive the indication by the first RLC layer entity, and,
discard, by the first RLC layer entity according to the indication, a second RLC SDU associated with the second PDCP PDU in the first RLC layer entity, wherein the second RLC SDU is not encapsulated and processed into an RLC PDU by the first RLC layer entity.
