The present invention relates to a wireless communications system and, more particularly, to a method for transmitting data under dual connectivity and an apparatus thereof. According to the present invention, a method for processing, by a packet data convergence protocol (PDCP) entity, transmission data comprises the following steps: configuring a plurality of radio link protocol (RLC) entities with respect to one wireless bearer, and dual connectivity; transferring at least one packet data convergence protocol protocol data unit (PDCP PDU) to each of the RLC entities; receiving a response signal with respect to the PDCP PDU transferred from each of the RLC entities; and setting a transmission window based on the response signal. |
