1. A method for transmitting a signal via a sidelink in a wireless communication system, the method performed by a User Equipment (UE) and comprising:
- receiving prioritization related radio resource control (RRC) information used to determine whether a sidelink transmission is prioritized over an uplink transmission;
determining a first transmission resource from a resource pool configured by a base station (BS) for transmission of a first sidelink data channel; and
performing the transmission of the first sidelink data channel or a first uplink transmission in a first time resource in which the first uplink transmission overlaps with the transmission of the first sidelink data channel in a time domain,wherein performing the transmission of the first sidelink data channel or the first uplink transmission in the first time resource further comprises;
determining whether the transmission of the first sidelink data channel is prioritized over the first uplink transmission, based on a per packet priority value of the first sidelink data channel and the prioritization related RRC information;
dropping the first uplink transmission and performing the transmission of the first sidelink data channel using the first transmission resource, according to a determination that the transmission of the first sidelink data channel is prioritized over the first uplink transmission based on the per packet priority value of the first sidelink data channel and the prioritization related RRC information;
ordropping the transmission of the first sidelink data channel and performing the first uplink transmission, according to a determination that the transmission of the first sidelink data channel is not prioritized over the first uplink transmission based on the per packet priority of the first sidelink data channel and the prioritization related RRC information.

Abstract
Disclosed is a method for a terminal to transmit and receive a signal in a wireless communication system using sidelinks. Specifically, the method comprises the steps of: determining a first transmission resource for transmitting a first sidelink signal; and determining a second transmission resource for transmitting an uplink signal, wherein if the first transmission resource and the second transmission resource overlap in a time domain, the first sidelink signal is transmitted with a priority over the uplink signal.
