Abstract

According to various embodiments of the present disclosure, an operation method of an electronic device in a wireless communication system may comprise the steps of: receiving configuration information from a base station (BS); receiving a plurality of synchronization signal blocks (SSBs) from a base station; transmitting one or more SSBs among the plurality of SSBs to the terminal based on the configuration information; receiving a physical random access channel (PRACH) preamble from the terminal in a time resource related to a special random access channel (RACH) occasion (RO) associated with a special SSB among the one or more SSBs; and transmitting the PRACH preamble to the base station based on the special SSB.
