Abstract: The present disclosure relates to a method for transmitting and receiving a signal in a wireless communication system and a device supporting same. The method comprises the steps of: obtaining message A comprising a physical random access channel (PRACH) preamble and a physical uplink shared channel (PUSCH); and transmitting the message A. The PUSCH is transmitted in one or more PUSCH occasions among continuous PUSCH occasions within a frequency domain and a time domain. The PRACH preamble is obtained from one or more predetermined PRACH preambles. The indices of the one or more PRACH preamble are mapped to the one or more PUSCH occasions in the ascending order.

Abstract: The present disclosure provides a method whereby a terminal transmits and receives signals for carrying out a random access channel (RACH) procedure in a wireless communication system. In particular, the method comprises: receiving first information about a transform precoder related to a physical uplink shared channel (PUSCH) transmitted via message A; on the basis of the first information, transmitting message A including the PUSCH and a physical random access channel (PRACH); and in response to message A, receiving message B including contention resolution information, wherein the first information may be used to indicate transform precoding for the PUSCH on the basis that the PUSCH is transmitted via message A.

Abstract: Disclosed is a method for transmitting and receiving a signal for a terminal to perform a random access channel procedure (RACH Procedure) in an unlicensed band. In particular, the method comprises: receiving a synchronization signal/physical broadcast channel block (SS/PBCH block); obtaining system information from a PBCH included in the SS/PBCH block; sending a first physical random access channel (PRACH) preamble through a message A on the basis of the system information; and receiving a random access response (RAR) through a message B related to contention resolution in response to the message A, wherein the first PRACH preamble is a PRACH preamble mapped to a physical uplink shared channel (PUSCH) occasion for the message A, and a window for reception of the message B may start after at least one symbol from the last symbol of the PUSCH occasion.

Abstract: A method of performing, by a user equipment (UE), a random access procedure in a wireless communication system is disclosed. The method includes receiving configuration information related to the random access procedure, transmitting a random access preamble and a physical uplink shared channel (PUSCH), and receiving a random access response (RAR) message. The PUSCH is transmitted based on a predetermined PUSCH transmission power. The predetermined PUSCH transmission power is based on preamble reception power information related to a transmission of the random access preamble and a specific offset.
