dot11NbrOfChangeBeacons BIs with the Old BSSIDset to the BSSID of the PBSSset to the MAC address of the candidate PCP, and the Remaining BIs field within the PCP Handover element set to the number of BIs remaining until the candidate PCP takes over the role of PCP for the PBSS‘s PCP.The initial value of the Remaining BIs field shall be equal to the Remaining BI field value last transmitted by the PCP in a the Handover Remaining BI field within the last transmitted Handover Request frame to the candidate PCP or equal to the Remaining BI field value last received by the PCP in the Handover Remaining BI field within the last received a Handover Request frame from the candidate PCP, whichever is later. A non-PCP STA receiving a DBand Beacon or Announce frame containing the PCP Handover element shall set the STA‘s local countdown counter to the value of the Remaining BIs field contained in the PCP Handover element. The STAs shall then decrease the local countdown counter by one at each TBTT and shall use the candidate PCP‘s address found in the New PCP Address field contained in the PCP Handover element as the new beacon filter address once the STA‘s local countdown reaches zero. When the countdown timer hits equals zero, the candidate PCP shall assume the role of PCP. In Annex D: Change the default values of MIB variable dot11MaxLostBeacons from to “4” “8”. Change the default of MIB variable dot11ImplicitHandoverLostBeacons from to “8” “4”.
