Apparatus and method for determining UWB multi-ranging priorities

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.

2. The apparatus of claim 1 , wherein the respective communication signal comprises one of a Bluetooth low energy (BLE) communication signal and a near field communication (NFC) communication signal.

3. The apparatus of claim 1 , wherein the one or more processors are configured to assign a higher UWB multi-ranging priority to a first digital key of the plurality of digital keys having a higher RSSI in the first plurality of communication signals.

4. The apparatus of claim 1 , wherein the one or more processors are configured to determine the respective UWB multi-ranging priority for the plurality of a digital keys having the identical RSSI based on the priorities of the basic connection order.

5. The apparatus of claim 1 , wherein the basic connection order comprises a preset connection order based on one of a digital key criterion and a manufacturer criterion.

6. A method of determining UWB multi-ranging priorities, the method comprising:

performing, by a first communication system, a first communication with a plurality of digital keys; and

determining, by a processor, UWB multi-ranging priorities for respective digital keys of the plurality of digital keys based soley on received signal strength indicators (RSSIs) of a plurality of communication signals received by the first communication system for each of the respective digital keys,

wherein, in the determining of the UWB multi-ranging priorities of the respective digital keys, the method further comprises, determining, by the processor, UWB nulti-ranging priorities for the plurality of digital keys by incorporating priorities according to basic connection order into the UWB multi-ranging priorities, wherein the UWB multi-ranging priorities are determined based on RSSIs of the plurality of communication signals when the plurality of digital keys each have an identical RSSI for the plurality of communication signals.

7. The method of claim 6 , wherein the plurality of communication signals comprises one of a Bluetooth low energy (BLE) communication signals and a near field communication (NFC) communication signals.

8. The method of claim 6 , wherein, in the determining of the UWB multi-ranging priorities of the respective digital keys, the method further comprises assigning, by the processor, a higher UWB multi-ranging priority to first digital keys of the plurality of digital keys having a higher RSSI for the plurality of communication signals.

9. The method of claim 6 , wherein, in the determining of the UWB multi-ranging priorities of the respective digital keys, the method further comprises, determining, by the processor, the UWB multi-ranging priorities for the plurality of digital keys having the identical RSSI of the plurality of communication signals based on the priorities of the basic connection order.

10. The method of claim 6 , wherein the basic connection order comprises a preset connection order based on one of a digital key criterion and a manufacturer criterion.

11. An apparatus for determining ultra wide band (UWB) multi-ranging priorities, the apparatus comprising:

a memory configured to store one or more instructions;

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 a first communication received for the 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 plurality of communication signals when the plurality of digital keys each have an identical RSSI for of the plurality of first communication signals, wherein, in the determining of the UWB multi ranging priorities of the respective digital keys.
