Abstract:
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for processing a PDCP SDU in a dual connectivity system, the method comprising: receiving a PDCP SDU (Packet Data Convergence Protocol Service Data Unit) from a upper layer; starting a timer associated with the PDCP SDU; checking whether a certain condition related to the PDCP SDU process is satisfied or not if the timer expires; and discarding the PDCP SDU if the certain condition related to the PDCP SDU process is satisfied.
