Abstract: Embodiments of a controller device and method for channel contention in a wireless network are generally described herein. The controller device may determine if a collision would occur for expected signal transmissions of a group of virtual devices, which may include one or more virtual access points (VAPs) and/or virtual stations (VSTAs). The determination of the collision may be based on transmission times and/or back-off intervals of the virtual devices. The controller device may transmit collision control messages to indicate whether colliding virtual devices are to delay signal transmissions. The VAPs may be configured to communicate with the VSTAs as access point (AP) instantiations. The VAPs may be configured to use different service set identifiers (SSIDs) and/or media access control (MAC) addresses in such communication.
