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: Disclosed herein are a method and a device for transmitting an uplink channel in a wireless communication system. According to the present disclosure, a UE transmits to a base station information associated with uplink transmission supported by the UE and the UE information includes a subset including at least one transmit precoding matrix indicator (TPMI) supported by the UE. The UE may receive from the base station uplink transmission information including a TPMI for transmitting an uplink channel and transmit to the base station the uplink channel based on the uplink transmission information, and the uplink channel may be transmitted through full transmission power configured by the base station based on a case where the TPMI is included in the subset.
