Abstract

An electronic device is provided. The electronic device includes a communication module configured to support ultra wideband (UWB) communication, and at least one processor operatively connected to the communication module, wherein the at least one processor is configured to control to transmit, to an external electronic device, a first packet including first information related to transmission of a second packet through the communication module in a slot corresponding to a transmission time of the first packet, to transmit, to the external electronic device, at least one or more second packets corresponding to the first information through the communication module in a slot corresponding to a transmission time of the second packet, wherein the first packet may be an STS packet configuration (SP) frame including a payload, and the at least one or more second packets for determining whether pointing may be an SP frame that does not include a frame payload.

First claim

What is claimed is:

1. An electronic device comprising:
a communication circuit configured to support ultra wideband (UWB) communication; and
at least one processor operatively connected to the communication circuit,
wherein the at least one processor is configured to control to:
transmit, to an external electronic device, a first packet including first information related to transmission of a second packet through the communication circuit in a slot duration of a slot, the slot duration corresponding to a transmission time of the first packet, and
transmit, to the external electronic device, at least one or more second packets corresponding to the first information through the communication circuit in a slot duration of a slot, the slot duration corresponding to a transmission time of the second packet,

wherein the first packet is a scrambled timestamp sequence (STS) packet configuration (SP) frame including a payload, and
wherein at least one or more second packets is an SP frame that does not include a frame payload.

2. The electronic device of claim 1 , wherein the at least one processor is further configured to control to transmit the first packet to the external electronic device in a first slot.

3. The electronic device of claim 2 , wherein the at least one processor is further configured to transmit the at least one or more second packets once every several slots from a slot following the first slot.

4. The electronic device of claim 2 , wherein the at least one processor is further configured to transmit the at least one or more second packets in one slot from a slot following the first slot.

5. The electronic device of claim 1 , wherein the first information is included in a physical layer payload of the first packet.

6. The electronic device of claim 1 ,
wherein the first packet is an STS packet configuration zero (SP0) frame, an STS packet configuration one (SP1) frame, and/or an STS packet configuration two (SP2) frame, and
wherein the first packet further comprises data in a physical layer payload thereof.

7. The electronic device of claim 6 , wherein the at least one processor is further configured to:
transmit the at least one or more second packets, and
transmit a third packet including the data to the external electronic device through the communication circuit.

8. The electronic device of claim 7 , wherein the third packet is the SP0 frame, the SP1 frame, or the SP2 frame.

9. The electronic device of claim 1 , wherein the first information comprises information on a number of times of transmission of the at least one or more second packets.

10. The electronic device of claim 9 , wherein the first information further comprises at least one of:
information on a transmission time interval of a UWB advertisement;
information on a transmission time interval of the at least one or more second packets; or
scrambled timestamp sequence index information.

11. An electronic device comprising:
a communication circuit configured to support ultra wideband (UWB) communication; and
at least one processor operatively connected to the communication circuit,
wherein the at least one processor is configured to control to:
receive, from an external electronic device, a first packet including first information related to transmission of at least one or more second packets in a slot duration of a slot, the slot duration corresponding to a transmission time of the first packet through the communication circuit,
receive, from the external electronic device, the at least one or more second packets corresponding to the first information in a slot duration of a slot, the slot duration corresponding to a transmission time of the at least one or more second packets through the communication circuit, and
determine whether the electronic device points the external electronic device based on the first packet and/or the at least one or more second packets,

wherein the first packet is a scrambled timestamp sequence (STS) packet configuration (SP) frame including a payload, and
wherein the at least one or more second packets is an SP frame that does not include a payload.

12. The electronic device of claim 11 , wherein the at least one processor is further configured to control to receive the first packet from the external electronic device in a first slot.

13. The electronic device of claim 12 , wherein the at least one processor is further configured to receive the at least one or more second packets once every several slots from a slot following the first slot.

14. The electronic device of claim 12 , wherein the at least one processor is further configured to receive the at least one or more second packets in one slot from a slot following the first slot.

15. The electronic device of claim 11 , wherein the first information comprises information on a number of times of transmission of the at least one or more second packets.

16. The electronic device of claim 15 , wherein the first information further comprises at least one of:
information on a transmission time interval of a UWB advertisement;
information on a transmission time interval of the at least one or more second packets; or
scrambled timestamp sequence index information.

17. The electronic device of claim 15 ,
wherein, if the number of times of a received at least one second packet is in a range of the number of times of transmission of the at least one second packet included in the received first information,
wherein the at least one processor is further configured to:
identify an angle of arrival or a field of view of the first packet or the second packet, and
determine that the external electronic device has been pointed based on the identified angle of arrival or field of view of the first packet or the second packet.

18. The electronic device of claim 16 , wherein, if the number of times of a received at least one second packet is in a range of the number of times of transmission of the at least one second packet included in the received first information, and if a transmission time interval of the received at least one or more second packets is in a range of a defined time interval, the at least one processor is further configured to:
identify an angle of arrival or a field of view of the first packet or the second packet, and
determine that the external electronic device has been pointed based on the identified angle of arrival or field of view of the first packet or the second packet.

19. The electronic device of claim 16 , wherein, if the number of times of a received at least one second packet is in a range of the number of times of transmission of the at least one or more second packets included in the received first information, the at least one processor is further configured to:
identify an angle of arrival or a field of view of the first packet or the second packet based on the scrambled timestamp sequence index information and a scrambled timestamp sequence index value of the at least one or more second packets, and
determine whether an external electronic device has been pointed based on the identified angle of arrival or field of view of the first packet or the second packet.

20. The electronic device of claim 11 ,
wherein the at least one processor is further configured to:
receive the at least one or more second packets, and
receive a third packet including data from the external electronic device through the communication circuit, and

wherein the third packet is an STS packet configuration zer
