1. A user equipment (UE) in a wireless communication system, the UE comprising:
a transceiver configured to:
receive, from a base station (BS), common information including first information on a number of repetitions for a physical uplink shared channel (PUSCH) for a message 3 (Msg 3) via a radio resource control (RRC) signaling, wherein a plurality of candidate values of the number of repetitions for the PUSCH for the Msg 3 is configured based on the first information, and
receive, from the BS, a random access response (RAR) message including an uplink (UL) grant that schedules the PUSCH for the Msg 3; and
a processor operably coupled with the transceiver, the processor configured to:
identify the number of repetitions for the PUSCH for the Msg 3 based on a field in the UL grant of RAR message, wherein a value of the field indicates one of the plurality of candidate values, and
identify whether to repeatedly transmit the PUSCH including the Msg 3 based on a comparison between a reference signal received power (RSRP) value and a threshold,
wherein the transceiver is further configured to transmit, to the BS, the PUSCH including the Msg 3 based on the number of repetitions identified based on the value of the field, and
wherein in case that the RSRP value is less than the threshold, the PUSCH including the Msg 3 is transmitted repeatedly on a selected UL BWP.
