Method for transmitting prach preamble in wireless communication system and apparatus therefor

The present specification proposes a method for transmitting a physical random access channel (PRACH) preamble in a wireless communication system. A method performed by a terminal may comprise the steps of: receiving information related to PRACH configuration from a base station; and transmitting a PRACH preamble to the base station on a PRACH frequency resource on the basis of the information related to the PRACH configuration, wherein the PRACH preamble is mapped to blocks, configured using a second number of resource blocks (RBs) interleaved at an interval of a first number of RBs, in the PRACH frequency resource.
