Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The AP may be configurable to operate as a controlling AP of a multi-AP group. The controlling AP may establish the multi-AP group by: transmitting one or more messages to advertise the multi-AP group; and exchanging signaling with one or more of the other APs of the multi-AP group. The signaling may include at least one message related to one of the other APs joining the multi-AP group. The controlling AP may establish the multi-AP group to enable usage of AP Trigger Frames (AP TFs) for coordination of resources to be used for downlink transmissions of the APs of the multi-AP group.
