Abstract

This disclosure describes systems, methods, and devices related to probes with service set identifier (SSID). A device may determine one or more access points (APs) in an enterprise extended service set (ESS). The device may identify a probe request received from a first station device, wherein the probe request comprises a service set element, wherein the service set element comprises a variable number of service set fields based on a number of APs in the ESS. The device may determine that a service set that matches at least one of the service set fields in the service set element. The device may cause to send a probe response to the first station device in response to the probe request.

First claim

What is claimed is:

1. A device, the device comprising processing circuitry coupled to storage, the processing circuitry configured to:
participate in a wireless communication with a plurality of co-located access points (APs) to form an enterprise extended service set (ESS), wherein at least one of the plurality of co-located APs comprise an AP with a 6 gigahertz (GHz) operational channels;
detect on a first wireless communication medium a probe request received from a first station device;
decode the probe request to identify a service set element comprising a short service set identifier (SSID) element having a size of 4 bytes;
extract the service set element from the decoded probe request;
compare the service set element to a list of service set fields that is based on a number of the plurality of co-located APs in the enterprise ESS;
determine that the service set element matches at least one of the service set fields in the list of service set fields;
generate a probe response that comprises a reduced neighbor report (RNR) that describes the at least one of the plurality of co-located APs operating at 6 GHz; and
transmit on the first wireless communication medium the probe response to the first station device in response to the probe request.

2. The device of claim 1 , wherein each of the plurality of co-located APs in the enterprise ESS have a same service set identifier (SSID).

3. The device of claim 1 , wherein the service set element is based on a scan performed at the first station device using a low frequency band.

4. The device of claim 1 , wherein the service set element has a size of at least four bytes.

5. The device of claim 1 , wherein the service set element comprises a BSSID list element or a short SSID list element.

6. The device of claim 5 , wherein the BSSID list element, the short SSID list element, or the short SSID element, each comprise a variable number of service set elements.

7. The device of claim 1 , further comprising a transceiver configured to transmit and receive wireless signals.

8. The device of claim 7 , further comprising an antenna coupled to the transceiver to cause to send the probe response.

9. A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:
participating in a wireless communication with a plurality of co-located access points (APs) to form an enterprise extended service set (ESS), wherein at least one of the plurality of co-located APs comprise an AP with a 6 gigahertz (GHz) operational channels;
detecting on a first wireless communication medium a probe request received from a first station device;
decoding the probe request to identify a service set element comprising a short service set identifier (SSID) element having a size of 4 bytes;
extracting the service set element from the decoded probe request;
comparing the service set element to a list of service set fields that is based on a number of the plurality of co-located APs in the enterprise ESS;
determining that the service set matches at least one of the service set fields in the list of service set fields;
generating a probe response that comprises a reduced neighbor report (RNR) that describes the at least one of the plurality of co-located APs operating at 6 GHz; and
transmitting on the first wireless communication medium the probe response to the first station device in response to the probe request.

10. The non-transitory computer-readable medium of claim 9 , wherein each of the plurality of co-located APs in the enterprise ESS have a same service set identifier (SSID).

11. The non-transitory computer-readable medium of claim 9 , wherein the service set element is based on a scan performed at the first station device using a low frequency band.

12. The non-transitory computer-readable medium of claim 9 , wherein the service set element has a size of at least four bytes.

13. The non-transitory computer-readable medium of claim 9 , wherein the service set element comprises a BSSID list element or a short SSID list element.

14. The non-transitory computer-readable medium of claim 13 , wherein the BSSID list element, the short SSID list element, or the short SSID element, each comprise a variable number of service set elements.

15. A method comprising:
participating in a wireless communication with a plurality of co-located access points (APs) to form an enterprise extended service set (ESS), wherein at least one of the plurality of co-located APs comprise an AP with a 6 gigahertz (GHz) operational channels;
detecting on a first wireless communication medium a probe request received from a first station device;
decoding the probe request to identify a service set element comprising a short service set identifier (SSID) element having a size of 4 bytes;
extracting the service set element from the decoded probe request;
comparing the service set element to a list of service set fields that is based on a number of the plurality of co-located APs in the enterprise ESS;
determining that the service set matches at least one of the service set fields in the list of service set fields;
generating a probe response that comprises a reduced neighbor report (RNR) that describes the at least one of the plurality of co-located APs operating at 6 GHz; and transmitting on the first wireless communication medium the probe response to the first station device in response to the probe request.

16. The method of claim 15 , wherein each of the plurality of co-located APs in the enterprise ESS have a same service set identifier (SSID).

17. The method of claim 15 , wherein the service set element is based on a scan performed at the first station device using a low frequency band.

18. The method of claim 15 , wherein the service set element has a size of at least four bytes.

19. The method of claim 15 , wherein the service set element comprises a BSSID list element or a short SSID list element.

20. The method of claim 19 , wherein the BSSID list element, the short SSID list element, or the short SSID element, each comprise a variable number of service set elements.
