Abstract: Disclosed is a method for transmitting and receiving signals to enable a terminal to perform a random access channel procedure (RACH procedure) in an unlicensed band. In particular, the method comprises: transmitting an uplink signal including a first physical random access channel (PRACH) and a first physical uplink shared channel (PUSCH) to a base station; and receiving, from the base station, a downlink signal related to contention resolution in response to the uplink signal, wherein a power ramping counter is used to set the transmission power of the uplink signal, and the value of the power ramping counter may be increased on the basis of a transmission spatial beam for the transmission of the uplink signal being configured in the same manner as a transmission spatial beam for the transmission of a PRACH prior to the uplink signal.

Abstract: A terminal receives a downlink signal on the basis of a random access channel procedure (RACH procedure) in an unlicensed band. In particular, a first physical random access channel (PRACH) preamble is transmitted through message A, in response to the message A, a random access response (RAR) is received through message B related to contention resolution, information on at least one DRX timer for setting a discontinuous reception (DRX) operation is received, and a downlink signal is received during an On duration on the basis of the at least one DRX timer, 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 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.
