Abstract: The present invention relates to a method of performing a discontinuous reception (DRX) operation by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: monitoring a wake up-signal (WUS) periodically in WUS transmission opportunities; if the WUS is successfully detected in the WUS transmission opportunities and if the WUS indicates to wake up, monitoring a physical downlink control channel (PDCCH) during a first DRX ON duration; and if the WUS is not successfully detected in the WUS transmission opportunities, monitoring the PDCCH during a second DRX ON duration, wherein the second DRX ON duration is longer than the first DRX ON duration.

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.
