Abstract

Embodiments for providing a query for location information for access points (APs) proximate to a reporting AP are generally described herein. A station may include a processor arranged to generate a Location Configuration Information (LCI) request having subelements arranged to query a reporting AP for a LCI report that includes location information regarding APs proximate to the reporting AP and a transceiver, coupled to the processor, the transceiver being arranged to send to the reporting AP the generated LCI request for the LCI report that includes location information regarding APs proximate to the reporting AP.

First claim

What is claimed is:

1. An apparatus comprising:
circuitry to cause a wireless station to:
generate a Location Configuration Information (LCI) request having a plurality of subelements configured to query for a LCI report; and
receive the LCI report from a reporting station, the LCI report including a floor information subelement configured to provide floor information of a reported station, the floor information subelement comprises a subelement Identifier (ID), a station floor information field including an indication of a floor number of the reported station, and a station height above floor information field indicating a height above a floor of the reported station; and

a network interface configured to send the LCI request and to receive the LCI report.

2. The apparatus of claim 1 , wherein the LCI report comprises latitude information, longitude information, and altitude information of the reported station.

3. The apparatus of claim 1 , wherein the LCI report includes a basic service set identifier (BSSID) subelement including a subelement identifier (ID) to identify the BSSID subelement, and a BSSID array field.

4. The apparatus of claim 1 , wherein the reporting station comprises an access point (AP).

5. The apparatus of claim 1 , wherein the reported station comprises one of the wireless station, an access point (AP) or a proximate AP.

6. The apparatus of claim 1 comprising one or more antennas.

7. An apparatus comprising:
circuitry to cause an access point (AP) to:
receive from a station a Location Configuration Information (LCI) request having a plurality of subelements; and
generate a LCI report including a floor information subelement to provide floor information of a reported station, the floor information subelement comprises a subelement Identifier (ID), a station floor information field including an indication of a floor number of the reported station, and a station height above floor information field indicating a height above a floor of the reported station; and

a network interface device configured to receive the LCI request and to send the LCI report.

8. The apparatus of claim 7 , wherein the LCI report comprises latitude information, longitude information, and altitude information.

9. The apparatus of claim 7 , wherein the LCI report includes a basic service set identifier (BSSID) subelement including a subelement identifier (ID) to identify the BSSID subelement, and a BSSID array field.

10. The apparatus of claim 7 , wherein the reported station comprises a proximate AP.

11. The apparatus of claim 7 comprising one or more antennas.

12. A product comprising one or more tangible computer readable non-transitory storage media comprising computer-executable instructions operable to, when executed by at least one processor logic, enable the at least one processor logic to:
generate a request to query a reporting station for a Location Configuration Information (LCI) of a reported station; and
receive from the reporting station a LCI report that includes a station floor information subelement corresponding to said reported station, the floor information subelement comprises a subelement Identifier (ID), a station floor information field including an indication of a floor number of the reported station, and a station height above floor information field indicating a height above a floor of the reported station.

13. The product of claim 12 , wherein the LCI report comprises latitude information, longitude information, and altitude information.

14. The product of claim 12 , wherein the instructions enable the at least one processor logic to:
receive, in response to the LCI request, the LCI report including a basic service set identifier (BSSID) subelement including a subelement identifier (ID) to identify the BSSID subelement, and a BSSID array field.

15. The product of claim 12 , wherein the reported station comprises one of the station, the access point or a proximate AP.

16. The product of claim 12 , wherein the reporting station comprises an access point (AP).

17. A product comprising one or more tangible computer readable non-transitory storage media comprising computer-executable instructions operable to, when executed by at least one processor logic, enable the at least one processor logic to:
receive a request to query a reporting station for a Location Configuration Information (LCI) of a reported station; and
send from the reporting station a LCI report that includes a station floor information subelement corresponding to said reported station, a basic service set identifier (BSSID) subelement including a subelement identifier (ID) to identify the BSSID subelement, and a BSSID array field, the floor information subelement comprises a subelement Identifier (ID), a station floor information field including an indication of a floor number of the reported station, and a station height above floor information field indicating a height above a floor of the reported station.

18. The product of claim 17 , wherein the reported station comprises a proximate Access Point (AP).

19. The product of claim 17 , wherein the LCI report comprises latitude information, longitude information, and altitude information.

20. A method of communicating location information by an access point (AP), the method comprising:
receiving from a station a Location Configuration Information (LCI) request having a plurality of subelements; and
generating a LCI report including a floor information subelement to provide floor information of a reported station, the floor information subelement comprises a subelement Identifier (ID), a station floor information field including an indication of a floor number of the reported station, and a station height above floor information field indicating a height above a floor of the reported station.

21. The method of claim 20 , wherein the reported station comprises a proximate Access Point (AP).

22. The method of claim 20 , wherein the LCI report comprises latitude information, longitude information, altitude information and a basic service set identifier (BSSID) subelement including a subelement identifier (ID) to identify the BSSID subelement, and a BSSID array field.

23. A method of communicating location information by a station, the method comprising:
generating a Location Configuration Information (LCI) request having a plurality of subelements configured to query for a LCI report; and
receiving the LCI report from a reporting station, the LCI report including a floor information subelement configured to provide floor information of a reported station, the floor information subelement comprises a subelement Identifier (ID), a station floor information field including an indication of a floor number of the reported station, and a station height above floor information field indicating a height above a floor of the reported station.

24. The method of claim 23 , wherein the reported station comprises a proximate Access Point (AP).

25. The method of claim 23 , wherein the LCI report comprises:
latitude information, longitude information, altitude information of the reported station, and a basic service set identifier (BSSID) subelement including a subelement identifier (ID) to identify the BSSID subelement, and a BSSID array field.
