transmit a first reservation forwarding message comprising at least the first indication of the one or more second sidelink resources to at least a third UE via one or more third sidelink resources;
receive a transmission of the first data packet from the second UE via the one or more second sidelink resources;
determine if the first UE is an intended recipient of the first data packet;
compare a reference signal received power (RSRP) value of the first reservation message received on the one or more first sidelink resources to a threshold value; and
