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： 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.

摘要： Methods, apparatuses, and computer readable media for communicating elements between multi-link devices are disclosed. Apparatuses of a first station (STA) affiliated with a multi-link device (MLD) are disclosed, where the apparatuses comprise processing circuitry configured to determine a sequence number as a next sequence number of a sequence number space where the sequence number space is indexed by a MLD media access control (MAC) address of a second MLD, and wherein the processing circuitry is further configured to encode a media access control (MAC) management protocol data unit (MMPDU) in a physical layer (PHY) protocol data unit (PPDU), the MMDPU including the sequence number, a frame body, and an address 1 field, the address 1 field indicating an address of a second station (STA) affiliated with the second MLD, and configure the first STA to transmit the PPDU to the second station.

摘要： A non-AP STA of a multi-link device (STA MLD) may be configured to encode a multi-link (ML) probe request frame for transmission to an access point STA (AP) of an AP MLD comprising a plurality of affiliated APs. When the probe request frame is sent outside the context of active scanning, to discover an AP of the AP MLD the ML probe request frame may be encoded to have an Address 1 field set to a broadcast address and an Address 3 field set to a BSSID of the AP, or encoded to have the Address 1 field set to a basic service set identity (BSSID) of the AP's BS. The non-AP STA may refrain from transmitting the ML probe request frame to the AP of the AP MLD in a corresponding link when another non-AP STA of the AP MLD has already received a ML probe response that included complete information from any one of the APs of the AP MLD in any link.

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.

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： Multi-link device (MLD) security association (SA) query and query response procedures are described. Any of the links between an access point (AP) MLD and a non-AP MLD may be used to initiate association, reassociation, or disassociation procedures using the SA query requests and responses. The SA query request or response from one of the stations (STAs) associated with the MLD is sent to a corresponding linked one of the STAs associated with the other MLD. The SA request or response is addressed to the other MLD rather than the STA of the other MLD. Retry timeouts and maximum timeouts for resending SA query requests are set by the AP MLD and the same across each of the links.
