摘要： Methods and devices are described in which the MU-RTS (multi-user request-to-send) trigger frame is compressed by having a single field trigger a group of users instead of an individual user. This technique also enables the indication of a set of transmission format parameters to the same group of users. In one embodiment, one Per-User Info field of the MU-RTS frame is used to indicate that the CTS (clear-to-send) response is to be transmitted by multiple stations instead of a having a Per-User Info field for each station.

摘要： 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 master AP of a multi-AP group. The master 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 master 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.
