Classification: CPC H | IPC H

Claim 0:
1. A method for performing a random access (RA) procedure by a user equipment (UE) in a wireless communication system, the method comprising:
determining which RA procedure is set among a 2-step RA procedure and a 4-step RA procedure based on a Reference Signal Received Power (RSRP) measured in a downlink bandwidth part (DL BWP);
based on the 2-step RA procedure being set, transmitting of a message A (msgA) including both a RA preamble and a physical uplink shared channel (PUSCH);
based on the 4-step RA procedure being set, transmitting a message 1 (msg1) consisting of the RA preamble;
establishing a Radio Resource Control (RRC) connection based on the RA procedure; and
based on (1) the RRC connection being established and (2) Discontinuous Reception (DRX) operation being configured, monitoring a Physical Downlink Control Channel (PDCCH) discontinuously using a DRX operation.
