Abstract: In the present disclosure, a UE transmits a random access preamble (RAP) on a physical random access channel (PRACH) and a control channel (CCCH) service data unit (SDU) on a physical uplink shared channel (PUSCH); and receives a medium access control (MAC) protocol data unit (PDU) based on transmitting the RAP and the CCCH SDU. The MAC PDU includes a MAC subheader. The MAC subheader includes a first indicator field regarding whether the MAC subheader include an RAP identity (ID) or not. The MAC subheader further includes a second indicator field regarding whether the MAC subheader includes a backoff indicator field or not, based on the first indicator field set to a value indicating that the MAC subheader does not include an RAP ID.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing reflective Quality of Service (QoS) in wireless communication system, the method comprising: receiving a DL PDU with a QoS flow ID via a DL DRB identified by a first DRB ID from a network; determining whether or not to update UL QoS flow to DRB mapping rule according to a value of the QoS flow ID; and transmitting UL data via a UL DRB mapped to QoS flow ID of the UL data based on the UL QoS flow to DRB mapping rule, wherein if the QoS flow ID is not a specific value but a first QoS flow ID, the UL QoS flow to DRB mapping rule is updated such that a UL DRB mapped to the first QoS flow ID is changed to a UL DRB identified by the first DRB ID, and wherein if the QoS flow ID is the specific value, the UE doesn't update the UL QoS flow to DRB mapping rule.

Abstract: A method and apparatus for reconstruction of a protocol data unit (PDU) for fast and reliable retransmission of a service data unit (SDU) after maximum retransmission is provided. Upon determining that a hybrid automatic repeat request (HARQ) retransmission of a first PDU including a specific SDU is unsuccessful, a wireless device constructs a second PDU including the first SDU which is prioritized to be included in the second PDU.
