1. A first user equipment (UE) comprising:
a memory comprising a universal integrated circuit card (UICC);
a transceiver to transmit and receive a wireless signal; and
a processor connected to the memory and the transceiver, wherein the processor is configured to:
determine to perform communication through a sidelink on an unlicensed band with a second UE while the first UE is in a state which is out of coverage of a base station,
based on the determination, identify pre-configuration information used for the unlicensed band and stored in the UICC,
obtain a priority threshold value for the sidelink on the unlicensed band from the pre-configuration information,
determine, based on the priority threshold value, whether to transmit data through the sidelink on the unlicensed band with the second UE,
identify data to be transmitted to the second UE through the sidelink on the unlicensed band,
identify priority of the data,
identify whether the priority of the data is less than the priority threshold value,
based on the priority of the data being less than the priority threshold value, wait for transmitting the data to transmit other data distinct from the data, and
after completing transmission of the other data, transmit the data to the second UE through the sidelink on the unlicensed band.
