摘要： Systems and techniques for random access to a wireless network are described herein. Components of a wireless station may obtain a back-off value. The components may also decode random access resource units from a frame transmitted to the wireless station from an access point of the wireless network. The components may decrement the back-off for each decoded random access frame. The wireless station may select this frame from a sequence of frames when the back-off reaches zero while decoding the random access resource units of this frame. The wireless station then selects the random access resource unit with a more favorable transmission metric than another random access resource unit of the frame and uses the selected random access resource unit to communicate with the access point.

摘要： 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.
