Assignee: LG ELECTRONICS INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 4:
5. A user equipment (UE) configured to perform a random access (RA) procedure in a wireless communication system, the UE comprising:
at least one radio frequency (RF) module;
at least one processor; and
at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations comprising:
determining which RA procedure is set among a 2-step RA procedure and a 4-step RA procedure based on a level of 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.
