Abstract: Embodiments of the present invention provide a method and apparatus for coordinated multi-AP channel access in a wireless network. A wireless AP that obtains a transmission opportunity (TXOP) (a “coordinator AP”) can grant one or more STAs or APs under control of the coordinator AP the use of some of the bandwidth granted by the TXOP. The STAs or APs that are granted the use of the bandwidth are referred to as “coordinated APs.” Thereafter, a coordinator AP or a coordinated AP can create a new basic service set (BSS) of devices for coordinating data transmissions. For example, the coordinated AP may serve as a relay, where the coordinated AP services devices in a new BSS by sending and receiving data with a coordinator AP in a different BSS.
