Abstract
According to various embodiments, a method is disclosed that includes detecting if a first cluster capable PCP/AP is within range of a non-PCP/non-AP STA; and transmitting a message to a second cluster capable PCP/AP associated with the non-PCP/non-AP STA requesting that the second cluster capable PCP/AP start or continue the use of clustering in a basic service set (BSS) of the second cluster capable PCP/AP.

A method comprising:
- detecting, by a non-personal basic service set control point (PCP)/access point (AP) station (STA), a first cluster capable PCP AP that is within range of the non-PCP/non-AP STA, wherein a first basic service set (BSS) includes the first cluster capable PCP/AP, and a second BSS includes a second cluster capable PCP/AP associated with the non-PCP/non-AP STA, wherein said detecting includes receiving a beacon frame from the first cluster capable PCP/AP and indicates whether the first BSS and the second BSS are overlapping;
- and
- if and only if the first BSS and the second BSS are overlapping, transmitting, by the non-PCP/non-AP STA, a message including a timing of when the detection occurred, information within the received beacon frame, or both, wherein the message reports to the second cluster capable PCP/AP that the first BSS and the second BSS are overlapping, and
- the message indicates a request to the second cluster capable PCP/AP to reschedule or create a specific time period associated with the second BSS, and/or the message indicates a request to the second cluster capable PCP/AP to start or continue use of clustering in the second BSS.
