Abstract: Embodiments of a non-access point (non-AP) EHT station (EHT STA) configured to operate as part of an STA multi-link logical entity (STA MLLE) comprising the EHT STA and one or more other non-AP EHT STAs are generally described herein. The STA MLLE is configured to be associated with an access point (AP) MLLE (AP MLLE) comprising a plurality of EHT APs. The EHT STA is configured to decode a beacon frame received from the EHT APs of the AP MLLE including a multi-link beacon check element to indicate which of the one or more multiple links has a critical update to its link parameters. When the multi-link beacon check element indicates an update to link parameters for the link between the EHT STA and its associated EHT AP, the EHT STA is to configured obtain the updated link parameters either waking-up at a target beacon transmission time (TBTT) or send a probe request.

Abstract: This disclosure describes systems, methods, and devices related to wake up receiver (WUR) frequency division multiple access (FDMA) transmission. A device may cause to send a wake up receiver (WUR) beacon frame on a WUR beacon operating channel to one or more station devices. The device may determine a first wake-up frame to be sent on a first WUR operating channel, wherein the first WUR operating channel is associated with one or more frequency division multiple access (FDMA) channels used for transmitting one or more wake-up frames to the one or more station devices. The device may determine to apply padding to the first wake-up frame based on a field included in a header of the first wake-up frame. The device may cause to send the first wake-up frame to a first station device of the one or more station devices.

Abstract: 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.
