Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for re-ordering a PDCP PDU in a dual connectivity system, the method comprising: configuring a radio bearer having one PDCP (Packet Data Convergence Protocol) entity and two RLC (Radio Link Control) enti-ties, wherein the PDCP entity enables a reordering function for PDCP PDUs (Protocol Data Unit) stored in a PDCP buffer; reconfiguring the radio bearer from having two RLC entities to having one RLC entity so that a first RLC entity is released; keeping the reordering func-tion enabled for the PDCP PDUs stored in the PDCP buffer if there is at least one PDCP PDU in the PDCP buffer after releasing the first RLC entity; and disabling the reordering function when the PDCP buffer becomes empty.
