Classification: CPC H | IPC H

Claim 9:
10. A terminal in a wireless communication system, the terminal comprising:
a transceiver; and
a controller configured to:
control the transceiver to receive a message including first information for configuring an uplink (UL), second information for configuring a supplementary uplink (SUL), and third information for performing a random access from a base station,
control the transceiver to receive a synchronization signal (SS) and physical broadcast channel (PBCH) block (SSB) from the base station,
measure a reference signal received power (RSRP) based on a secondary synchronization signal (SSS) included in the SSB,
compare the RSRP with a threshold value included in the third information for performing the random access,
determine one carrier of an UL carrier or an SUL carrier to perform the random access based on a result of a comparison, and
control the transceiver to transmit a random access preamble on the determined carrier based on the first information or the second information.
