Abstract: The present invention relates to a method of performing uplink transmission by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: receiving a configured grant (CG) activation command for a configured uplink grant; based on a size of the configured uplink grant not matching with a size of a pending protocol data unit (PDU) associated with an identified HARQ process, flushing a Hybrid Automatic Repeat Request (HARQ) buffer of the identified HARQ process; and transmitting a CG confirmation medium access control (MAC) control element (CE) using the identified HARQ process.

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.
