    Abstract: The present disclosure provides a method for performing a random-access channel procedure (RACH procedure) by a terminal in a wireless communication system. Specifically, the method may comprise transmitting a first physical random-access channel (PRACH) preamble through message A on the basis of a RACH occasion, and receiving, as a response to message A, a random-access response (RAR) through message B related to contention resolution, wherein on the basis of the first PRACH preamble corresponding to a PRACH preamble mapped to a physical uplink shared channel (PUSCH) occasion, message A comprises the first PRACH preamble and a PUSCH based on the mapped PUSCH occasion, and on the basis of the first PRACH preamble corresponding to a PRACH preamble failed to be mapped to a PUSCH occasion, message A comprises the first PRACH preamble.
