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. ## Claims ### Claim 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;
