Method for transmitting TCP ACK packet in wireless communication system and a device therefor
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting TCP ACK packet in wireless communication system, the method comprising: receiving a packet with a first QoS flow ID for a PDU session from an upper layer, wherein a first DRB for transmitting only TCP ACK packet is configured for the PDU session; checking whether or not the received packet is a TCP ACK packet; and if the received packet is the TCP ACK packet, delivering a PDU including the received packet to a lower layer via the first DRB, wherein the first QoS flow ID of the received packet is associated with a second DRB according to QoS flow to DRB mapping rule of the PDU session.
