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 Target Wakeup Time (TWT) Channel field contains a bitmap indicating a temporary primary channel for using during a TWT Service Period (SP). The temporary primary channel is determined through a negotiation between a requesting STA and a responding STA, and the responding STA assigns resource units (RUs) to the requesting STA according to the temporary primary channel. After the TWT SP, the requesting STA switches back to a primary channel.
