## Abstract

Systems and methods are provided for multiple basic service set identifier (MBSSID) beaconing (from an access point (AP) standpoint) and MBSSID/virtual AP (VAP) scanning (from a client device perspective). To facilitate easier discovery of mesh APs/VAPs, BSSIDs associated with mesh VAPs can be advertised more frequently, e.g., being broadcast as a transmitted or non-transmitted BSSID in each MBSSID beacon. Additionally, information regarding mesh VAPs, such as mesh capability information, can be provided via intermediate discovery beacons or frames such that out-of-band scanning mechanisms can discover mesh VAPs faster. Additionally still, the existence of mesh VAPs can be advertised in a dedicated field of an MBSSID beacon.

## Claims

### Claim 1

An access point (AP), comprising:
a processor; and
a memory operatively connected to the processor, and including computer code that when executed, causes the processor to:
assign a basic service set identifier (BSSID) to a virtual AP (VAP) configured as a mesh VAP on the AP;
broadcast a plurality of multiple BSSID (MBSSID) beacons including the BSSID information of the mesh VAP that indicates existence of the mesh VAP in a dedicated information element of the MBSSID; and
in between each of the plurality of MBSSID beacons, transmit a plurality of fast initial link setup (FILS) discovery frames at a periodicity less than a periodicity of the MBSSID beacons, each of the FILS discovery frames including mesh capability information associated with the mesh VAP.

### Claim 2 (depends on 1)

The AP of claim 1, wherein mesh information of the mesh VAP is integrated into a reserved field of a Reduced Neighbor Report (RNR) information element.

### Claim 3 (depends on 1)

The AP of claim 1, wherein the dedicated information element is part of a transmitted BSSID transmitted with each of the plurality of MBSSID beacons.

### Claim 4 (depends on 3)

The AP of claim 3, wherein the indication of the existence of the mesh VAP in the transmitted BSSID is included in each of the plurality of MBSSID beacons instead of including the mesh information associated with the mesh VAP in the RNR information element.

### Claim 5 (depends on 3)

The AP of claim 3, wherein the indication of the existence of the mesh VAP in the transmitted BSSID is included in each of the plurality of MBSSID beacons in addition to including the mesh information associated with the mesh VAP in the RNR information element.
