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 for performing an initial cell access, according to an embodiment of the present disclosure, receives a PBCH signal of a first cell via a cell search, receives SIB1-scheduling information on a CSS set related to the PBCH signal, and determines whether to perform a remaining access procedure on the first cell, on the basis of the SIB1-scheduling information, wherein the terminal is a second type terminal in which the capability is reduced to support a bandwidth narrower than that of a first type terminal, and the terminal may determine, as the second type terminal, whether an access to the first cell is allowed, on the basis of the state of a bit reserved so as not to be used by the first type terminal within the SIB1-scheduling information.

Abstract: A method and apparatus for discontinuous reception (DRX) of downlink signal for sidelink transmission is provided. A wireless device operating in a wireless communication system monitors a physical downlink control channel (PDCCH) carrying a sidelink grant during an active time including a time interval for which a scheduling request (SR) is transmitted on a physical uplink control channel (PUCCH) and is pending, based on the SR being triggered for a sidelink buffer status report (SL BSR) and/or a sidelink channel state information (SL CSI) reporting.

Abstract: A method and apparatus for hybrid automatic repeat request (HARQ) feedback based on a communication range and location of devices is provided. A first device (e.g., receiving user equipment in sidelink) receives, from a second device (e.g., transmitting user equipment in sidelink, control information including 1) a communication range, and 2) a location of the second device. The first device determines whether to perform a hybrid automatic repeat request (HARQ) feedback based on whether a distance between a location of the first device for the control information and the location of the second device is smaller or equal to the communication range.
