摘要： An access point (AP) station (STA) (AP STA) may be configured to operate as a multi-AP controller in a multi-AP network. A multi-AP group formation message is encoded for transmission to other APs in the multi-AP network. The multi-AP group formation message is encoded to notify the APs of the formation of an extremely-high throughput (EHT) multi-AP group, to designate whether an AP is a member of an EHT multi-AP group, and whether an AP can take the role of a coordinator AP or coordinated AP within the EHT multi-AP group. For multi-AP joint processing, the AP STA is further configured to encode an AP trigger frame for transmission to the APs in the multi-AP network. The AP trigger frame is to trigger physical layer (PHY) and medium-access control layer (MAC) parameter synchronization. The AP trigger frame is to trigger transmission of aggregated MAC protocol data units (A-MPDUs) by the APs that include MAC parameters and PHY parameters.

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： Multi-link device (MLD) devices and transitions are described. The MAC addresses of the AP MLD and non-AP MLD are used to generate keys for different fast transitions (FT) between a non-AP MLD and an AP MLD. In an FT initial mobility domain operation, the AP MLD MAC address is used as the R1KH-ID and the non-AP MLD MAC address is used as the S0KH-ID and S1KH-ID. The MAC addresses are exchanged in Authentication Request/Response or Association Request/Response messages and the GTK/IGTK/BIGTK are delivered in a single FT 4-way handshake. In a fast MLD transition to an AP MLD in the same ESS, the other AP MLD MAC address is used as the R1KH-ID and the non-AP MLD MAC address is used as the S1KH-ID. The MAC addresses are exchanged in Authentication Request/Response or Association Request/Response messages and the GTK/IGTK/BIGTK are delivered in an FTE.

摘要： Embodiments of a high efficiency subchannel selective transmission (HE SST) access point (AP) and an HE SST station (STA) are generally described herein. The HE SST AP may determine a temporary primary channel for an HE SST STA. The HE SST AP may communicate with the HE SST STA in a plurality of channels that includes the temporary primary channel and further includes a primary channel. The HE SST AP may determine trigger-enabled target wake time service periods (TWT SPs) for exchange of frames between the HE SST AP and the HE SST STA on the temporary primary channel. The trigger-enabled TWT SPs may be determined to not overlap with target beacon transmission times (TBTTs) at which beacon frames that include delivery traffic indication maps (DTIMs) are to be sent on the primary channel by the HE SST AP.

摘要： This disclosure describes systems, methods, and devices related to group-addressed transmissions in wireless communications. A device may determine a first time associated with a first multicast transmission including a first basic service set (BSS) identifier (BSSID) associated with a first BSS of a multi-BSSID set including the first BSS and a second BSS. The device may send a frame including the first time, the first BSSID, wherein the frame indicates that the second BSS may ignore multicast transmissions at the first time, and wherein the first time is during a beacon interval associated with a beacon addressed to the multi-BSSID set. The device may send the first multicast transmission at the first time and may send a second multicast transmission at a second time, wherein the second time is during the beacon interval, and wherein the second multicast transmission includes a second BSSID associated with the second BSS.

摘要： This disclosure describes systems, methods, and devices related to intra-basic service set (BSS) signaling for multiple access points (APs). A device may determine one or more access points (APs), wherein the one or more APs are in a set of multiple basic service sets (BSSs) identified as intra-BSS. The device may include, in a first frame, a high-efficiency operation element comprising a bit associated with an indicator of the set of multiple BSSs. The device may include, in a second frame, an association identification (AID) value, wherein the AID value is associated with the device. The device may cause to send the first frame a first station device of one or more station devices. The device may cause to send the second frame to a second station device of the one or more station devices.

A device may determine a multi-link communication with a first multi-link device comprising two or more links associated with two or more station devices (STAs) included in the first multi-link device. The device may determine a first medium access control (MAC) address associated with a first link of the two or more links. The device may determine a second MAC address associated with a second link of the two or more links. The device may generate one or more pairwise security keys to be used in the multi-link communication on the two or more links.

摘要： This disclosure describes systems, methods, and devices related to multi-link device (MLD) data continuity. An MLD device may set up one or more links with a station multi-link device (STA MLD), wherein the STA MLD comprises one or more logical entities defining separate station devices. The MLD device may transmit a data packet associated with a traffic identifier (TID) to the STA MLD. The MLD device may determine that the data packet was not received by the STA MLD. The MLD device may retransmit the data packet to the STA MLD. The MLD device may increment a retransmit counter every time the data packet is retransmitted. The MLD device may refrain from transmitting a second data packet until the data packet is dropped or successfully received by the STA MLD.

摘要： This disclosure describes systems, methods, and devices related to security for multi-link operations. A multi-link device (MLD) may establish a first communication link between a first device of the MLD and a first device of a second MLD, and a second communication link between a second device of the MLD and a second device of the second MLD. The MLD may generate a group-addressed message. The MLD may protect the group-addressed message using a first key or a first integrity key. The MLD may protect the group-addressed message using a second key or a second integrity key. The MLD may send, using the first communication link, the group-addressed message protected using the first key or the first integrity key, and may send, using the second communication link, the group-addressed message protected using the second key or the second integrity key.
