Method for reordering a packet data convergence protocol packet data unit at a user equipment in a dual connectivity system and device therefor
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: receiving a first PDCP PDU from a first RLC entity of a radio bearer; starting a reordering function if the first PDCP PDU is detected to be out of sequence; storing the first PDCP PDU in the PDCP entity; receiving a second PDCP PDU from a first RLC entity or a second RLC entity while the reordering function is running; and delivering at least one stored PDCP PDU with an associated COUNT value less than x+1 in ascending order of an associated COUNT value to an upper layer, if the second PDCP PDU is received from a second RLC entity.
