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: 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.
