Abstract: A method performed by a terminal in a wireless communication system according to an embodiment of the present disclosure comprises the steps of: receiving a group-common transmission regarding a TB from a network; transmitting hybrid automatic repeat request (HARQ) acknowledgement (ACK) or non-acknowledgement (NACK) information regarding the group-common transmission to the network, on the basis of whether the TB is successfully decoded; and receiving first transmission from the network after a first round trip time (RTT) has lapsed since transmission of the HARQ ACK/NACK information regarding the group-common transmission. The first transmission corresponds to group-common transmission or terminal-specific transmission. The first transmission may correspond to retransmission of the TB on the basis that the first transmission is terminal-specific transmission associated with the same HARQ process as the group-common transmission, and that a new data indicator (NDI) value is not toggled.

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 method and device for transmitting/receiving a signal in a wireless communication system, according to one embodiment of the present invention, transmits a PUCCH including UCI. With respect to a resource for transmitting the PUCCH, the PUCCH is determined to be associated with a first interlace, among the first interlace and a second interlace, on the basis that: (i) the first interlace, and the second interlace having a higher index than that of the first interlace are configured by means of information on the PUCCH resource; and (ii) the number of physical resource blocks (PRBs) for transmitting the UCI is equal to or less than the number of PRBs of the first interlace.
