A first apparatus for performing sidelink communication,

• the first apparatus comprising:
• one or more memories storing instructions;
• one or more transceivers;
• and
• one or more processors connected to the one or more memories and the one or more transceivers, wherein the one or more processors execute the instructions to:
• transmit a first transport block to a second apparatus on a resource allocated by a first sidelink (SL) grant received from a base station;
• transmit a system information request message requesting system information to the base station;
• transmit a second transport block to the second apparatus on an exceptional resource pool based on that the system information request message is transmitted to the base station;
• and
• receive first system information related to the system information request message, from the base station.

An apparatus configured to control a first user equipment (UE), the apparatus comprising:

• one or more processors;
• and
• one or more memories operably connectable to the one or more processors and storing instructions, wherein the one or more processors execute the instructions to:
• transmit a first transport block to a second UE on a resource allocated by a first sidelink (SL) grant received from a base station;
• transmit a system information request message requesting system information to the base station;
• transmit a second transport block to the second UE on an exceptional resource pool based on that the system information request message is transmitted to the base station;
• and
• receive first system information related to the system information request message, from the base station.
