Abstract

In the present disclosure, a UE transmits a random access preamble (RAP) on a physical random access channel (PRACH) and a common control channel (CCCH) service data unit (SDU) on a physical uplink channel (PUSCH). The UE receives a medium access control (MAC) protocol data unit (PDU) based on transmitting the RAP and the CCCH SDU. The MAC PDU may include a MAC PDU associated with a contention resolution identity (CRID) in the MAC PDU. The UE determines whether a MAC SDU is present or not in the MAC PDU, based on the MAC SDU indicator associated with a CRID in the MAC PDU in a state in which the CRID matches the CCCH SDU.
