Abstract: The present disclosure provides a method for receiving a downlink signal on the basis of a random-access channel procedure (RACH procedure) by a terminal in an unlicensed band. Specifically, the method may comprise: on the basis of a power ramping counter, configuring transmission power for message A including a first physical random-access channel (PRACH) and a first physical uplink shared channel (PUSCH); on the basis of the transmission power, transmitting message A to a base station; and receiving contention resolution-related message B from the base station in response to message A, wherein an increase is made on the basis that a transmission spatial beam for transmission of message A is configured to be identical to a transmission spatial beam related to transmission of a PRACH preceding message A.

Abstract: The present disclosure discloses a method for receiving, by a terminal, a physical downlink control channel (PDCCH) in an unlicensed band. In particular, the method comprises transmitting, to a base station, a message A including a first physical random access channel (PRACH) and a first physical uplink shared channel (PUSCH), according to transmission power set by a power ramping counter, and performing a random access procedure (RACH procedure) on the base station by receiving, from the base station, a message B related to contention resolution in response to the message A, wherein a value of the power ramping counter may increase on the basis that a transmission spatial beam for transmission of the message A is configured identically to a transmission spatial beam related to transmission of a PRACH prior to the message A.

Abstract: A method of transmitting and receiving a signal for a random access channel (RACH) procedure by a user equipment (UE) in a wireless communication system is disclosed. The method includes transmitting a message A including a physical random access channel (PRACH) and a physical uplink shared channel (PUSCH), and receiving a message B related to contention resolution in response to the message A. Transmission power for a retransmission of the message A is configured based on that a counter value related to the transmission power is incremented or maintained, the counter value is maintained based on that a transmission spatial filter related to the PRACH is changed for the retransmission of the message A, and the counter value is used for configuring the transmission power based on that the PRACH and the PUSCH are transmitted via the message A.
