    Abstract: The present invention relates to a method of transmitting a protocol data unit (PDU) by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of receiving a service data unit (SDU) from an upper layer; generating the PDU including the SDU and an integrity protection indicator, based on whether to perform integrity protection for the SDU or not; and transmitting the PDU to a network, wherein, when the integrity protection for the SDU is performed, a Message Authentication Code-Integrity (MAC-I) is included at an end of the PDU and the integrity protection indicator represents that the SDU is integrity protected, wherein, when the integrity protection for the SDU is not performed, the MAC-I is not included in the PDU and the integrity protection indicator represents that the SDU is not integrity protected.
