Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. A method by a base station for performing a random access in a wireless communication system, the method comprising:
generating a message including first information for configuring an uplink (UL), second information for configuring a supplementary uplink (SUL), and third information for performing the random access;
transmitting the generated message to a terminal;
transmitting a synchronization signal (SS) and physical broadcast channel (PBCH) block (SSB) to the terminal; and
receiving a random access preamble for performing the random access on a carrier,
wherein a reference signal received power (RSRP) is measured, by the terminal, based on a secondary synchronization signal (SSS) included in the SSB, the RSRP is compared with a threshold value included in the third information for performing the random access, one carrier of an UL carrier or an SUL carrier is determined to perform the random access based on a result of a comparison, and the random access preamble is received on the determined carrier.
