Abstract
Embodiments of the present invention provide a method and apparatus for providing wideband channel access to wireless devices, such as 20 MHz only wireless stations. A trigger frame is transmitted by a wireless AP to a wireless STA over a secondary wireless channel. An HE TB PPDU is received by the wireless AP from the wireless STA over the secondary wireless channel responsive to the trigger frame. The devices can switch operating channels for wireless communication to the secondary wireless channel within an existing TXOP.
