1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
transmitting a message related to 2-step random access procedure, wherein the message comprises a first physical random access channel (PRACH) preamble on at least one valid PRACH occasion among a plurality of valid PRACH occasions in a PRACH slot; and
obtaining information related to a random access response (RAR) in response to the message,
wherein the first PRACH preamble is included in a plurality of PRACH preambles related to the plurality of valid PRACH occasions,
wherein based on a plurality of consecutive PRACH preambles included in the plurality of PRACH preambles being mapped to one valid physical uplink shared channel (PUSCH) occasion, the plurality of PRACH preambles are mapped to a first plurality of PUSCH occasions among a plurality of PUSCH occasions, and
wherein a second PRACH preamble which is not mapped to any one of the first plurality of PUSCH occasions is available to be transmitted in the 2-step random access procedure.
