Abstract
Embodiments of switching between BSSs using On-Channel Tunneling (OCT) are generally described herein. The OCT process is used to scan and associate with a co-located or non-co-located peer AP. The OCT process includes: sending a probe / reauthentication / reassociation request frame from a STA to a peer AP using an OCT request frame; and receiving a probe / reauthentication / reassociation response frame from a peer AP using another OCT request frame. The communication between the STA and the AP is in the same frequency band as the OCT communication between the AP and the peer AP or in a different frequency band.
