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.

Controller device and method for channel contention between virtual access points (VAP) and virtual stations (VSTA)

A communication system comprises a transmission controller configured to send transmissions to one or more transceivers; a device performance analyzer configured to receive feedback about the reception of transmissions at said transceivers, and to analyze such feedback to estimate the quality of communication with an existing ATW and to output a quality information; an ATW performance analyzer configured to receive the quality information of the device performance analyzer and to perform further analysis to estimate whether the ATW should be retained as in current operation or modified based on feedback received from said transceivers and to output an estimate information; or ATW feedback analyzer configured to receive feedback about the ATW from said other transceivers, and to estimate based on such feedback whether the ATW should be retained as in current operation or modified based on feedback received from said transceivers; and an ATW estimator configured to receive the estimate information of the ATW performance analyzer, to retain the current ATW unmodified if that is the estimate of the ATW performance analyzer and to communicate such retention to the transmission controller, and to modify the current ATW if that is the estimate information of the ATW performance analyzer and to communicate the modified ATW to a flow controller; wherein said flow controller is configured to receive the modified ATW from the ATW estimator, and to communicate the modified ATW to the transmission controller. The system id adapted to carry out respective methods.
