摘要： Methods and systems for authenticated wake-up radio frames are disclosed. In one aspect, a method includes generating a wake-up radio (WUR) integrity group key (IGTK) for authentication of WUR frames when received by a wake-up radio (WURx). The WUR IGTK may be identified via a key identifier in the WUR frame. The key identifier may be updated when the WUR IGTK is updated, facilitating WUR IGTK key updating across multiple associated stations.

摘要： Embodiments of a multi-link access point (AP) device, station (STA) and method of communication are generally described herein. The multi-link AP device may comprise multiple APs. The multi-link AP device may encode a frame for transmission by one of the APs of the multi-link AP device. The multi-link AP device may encode the frame to include signaling to enable multi-link discovery of the APs of the multi-link AP device. The multi-link AP device may encode the signaling to include: a reduced neighbor report (RNR) element that identifies the APs of the multi-link AP device, and a multiple AP element. The multiple AP element may be configurable to include: common information for the APs of the multi-link AP device, and per-AP sub-elements that include per-AP information related to the APs of the multi-link AP device.

摘要： Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The AP may be included in a plurality of APs affiliated with a multi-link AP logical entity. As part of a multi-link AP logical entity, the plurality of APs may share a common medium access control (MAC) data service interface to an upper layer. The AP may exchange signaling with an STA as part of a multi-link setup process between the multi-link TP logical entity and a multi-link non-AP logical entity. The STA may be included in a plurality of STAs affiliated with the multi-link non-AP logical entity. The multi-link setup process may establish a link between each AP of the plurality of APs and a corresponding STA of the plurality of STAs.

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.

摘要： An extremely high-throughput (EHT) station (STA) is configured for transmission of a control response frame for rate selection. In response to a frame carried in an EHT PPDU soliciting a control response frame, the EHT STA may calculate a duration of a non-HT PPDU containing the control response frame sent at a primary rate. The EHT STA may also encode a high-efficient (HE) single-user (SU) PPDU (HE SU PPDU) for transmission to carry the solicited control response frame when a transmit time of the encoded HE SU PPDU is less than the calculated duration of the non-HT PPDU, or encode an EHT PPDU for transmission to carry the solicited control response frame when a transmit time of the encoded EHT PPDU is less than the calculated duration of the non-HT PPDU. A reduction in overhead may be achieved by using an HE SU PPDU or an EHT PPDU instead of a non-HT PPDU to carry a solicited control response frame.

摘要： An access point (AP) station (STA) (AP STA) that is part of an AP multi-link device (MLD) may be configured as a reporting AP may encode a BSS Transition Management (BTM) request frame for transmission to one or more associated non-AP stations (STAs). The BTM request frame may include a neighbor report element encoded to include information about one or more neighbor APs. The neighbor report element may indicate whether the one or more neighbor APs identified in the neighbor report element are part of an AP MLD and, when a neighbor AP is indicated to be part of an AP MLD whether the reporting AP is part of the indicated AP MLD. The AP STA may decode a reassociation frame from one of the non-AP STAs for transition from one of the AP STAs of the AP MLD to one of the neighbor APs.
