摘要： This disclosure describes systems, methods, and devices related to using protected beacon frames in wireless communications. A device may determine a beacon management element of a beacon frame body and may determine an integrity group key identifier of the beacon management element, wherein the integrity group key identifier is associated with a basic service set (BSS). The device may determine, based on the integrity group key identifier, a management integrity check (MIC) field of the beacon management element. The device may generate a beacon frame including the beacon frame body. The device may send the beacon frame.

摘要： This disclosure describes systems, methods, and devices related to synched group key rekeying. A device may determine a first security key used for group-addressed management frames. The device may perform a security key rekeying to use a second security key in place of the first security key. The device may cause to send the second security key to a first station device of one or more station devices. The device may cause to send a first beacon frame comprising a switch announcement information element (IE) associated with the second security key. The device may cause to send a second beacon frame, wherein the second beacon frame does not comprise the switch announcement IE. The device may determine to switch to the second security key based on the switch announcement IE.

摘要： This disclosure describes systems, methods, and devices related to beacon protection rekeying and attack detection. A device may set a first beacon integrity group transient key (BIGTK). The device may generate a first frame including a first indication of a second BIGTK to be used for a first integrity analysis of the first frame, a second indication of the first BIGTK, and a third indication that the first BIGTK is to be used for a second integrity analysis of a second frame to be sent after the first frame. The device may send the first frame, and may generate the second frame, the second frame including an indication that the first BIGTK is to be used for the second integrity analysis of the second frame. The device may send the second frame.

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： This disclosure describes systems, methods, and devices related to enhanced frame exchange. A device may generate a first subset of a plurality of fields, wherein the first subset is mandatory in a probe request frame. The device may generate a second subset of the plurality of fields, wherein the second subset is optional in the probe request frame regardless of capability information of the device. The device may generate the probe request frame comprising the first subset and the second subset. The device may cause to send the probe request frame to an access point (AP) device.

摘要： This disclosure describes systems, methods, and devices related to basic service set (BSS) information spreading indication. A device may determine one or more collocated access points (APs). The device may determine a target beacon transmission time (TBTT) associated with a beacon interval. The device may determine a first beacon frame comprising a first multiple basic service set identification (BSSID) element. The device may determine a second beacon frame comprising a second multiple BSSID element. The device may determine a time period associated with the first beacon frame and the second beacon frame. The device may cause to send the first beacon frame at a first time to one or more station devices. The device may cause to send the second beacon frame at a second time to the one or more station devices.

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.

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： For example, a wireless communication station (STA) may be configured to set a Message Integrity Code (MIC) in a MIC field to protect contents of a control frame according to a Galois Message Authentication Code with 256-bit cipher-key (GMAC-256) protection mechanism. For example, the MIC may be based on a Packet Number (PN). For example, a size of the MIC field may be less than 16 bytes. For example, the STA may be configured to set a PN field based on the PN. For example, a size of the PN field may be less than 6 bytes. For example, the STA may be configured to transmit the control frame including the MIC field and the PN field.
