1. An apparatus for determining ultra wide band (UWB) multi-ranging priorities, the apparatus comprising:
a memory configured to store one or more instructions;
a first communication system configured to perform a first communication with a plurality of digital keys; and
one or more processors configured to execute the one or more instructions to determine a respective UWB multi-ranging priority of a plurality of UWB multi-ranging priorities for each respective digital key of the plurality of digital keys based on received signal strength indicators (RSSIs) of a first plurality of communication signals of the first communication received by the first communication system for the each respective digital key, wherein the UWB multi-ranging priority is set for each digital key based only on the RSSI of the first communication signals of each respective digital key,
wherein the one or more processors are configured to determine the respective UWB multi-ranging priority of the plurality of digital keys by incorporating priorities according to a basic connection order into the plurality of UWB multi-ranging priorities, wherein the priority is determined based on the RSSIs of the first priority of communication signals when the plurality of digital keys each have an identical RSSI for the plurality of first communication signals.
