Abstract: Methods, systems and apparatuses for performing enhanced integrity protection techniques by an access point (AP) and non-AP are described. A station (STA) can receive, from an access point (AP), an integrity protection (IP) capability request and transmit an IP capability response to the AP. The STA can receive, from the AP, one or more downlink (DL) frames comprising at least one adjusted parameter field of a plurality of parameter fields. The STA can verify, based on at least one value of the adjusted parameter field or one or more parameter fields of the plurality of parameter fields, that the one or more DL frames have been correctly received from the AP.

Abstract: A method of an initiating station (ISTA) can include transmitting, to a responding station (RSTA), a first indicator indicating whether the ISTA supports one or more optional preamble puncture patterns. Additionally, the method can include receiving, from the RSTA, a second indicator indicating whether the RSTA supports optional preamble puncture patterns. Furthermore and responsive to determining that the ISTA and the RSTA support optional preamble puncture patterns, the method can further include starting, according to at least one of the optional preamble puncture patterns, a ranging session with the RSTA.

Abstract: During operation, an electronic device may encrypt an A-control subfield. Then, the electronic device may provide the frame addressed to a second electronic device, where the frame includes a media access control (MAC) header and the MAC header includes the A-control subfield that is encrypted. Note that the encrypted A-control subfield may be jointly encrypted with data in a payload in the frame. Moreover, the encrypted A-control subfield may be separated from the payload in the frame by one or more additional subfields or may be adjacent to the payload in the frame. Furthermore, the MAC header may include an indicator that indicates whether the A-control subfield is encrypted. Additionally, the frame may include a preamble that indicates whether the A-control subfield is encrypted. The frame may be received by the second electronic device. After receiving the frame, the second electronic device may decrypt the A-control subfield.

Abstract: Techniques are disclosed for obfuscation in a privacy beacon. An example method includes the first device receiving, from a second communication device, a beacon frame comprising a medium access control (MAC) header and an encrypted beacon frame field, the MAC header comprising an obfuscated timing synchronization field (TSF). The first device can select a key for de-obfuscating the TSF based at least in part on information associated with the beacon frame. The first device can de-obfuscate the TSF based at least in part on the key. The first device can decrypt the encrypted beacon frame field of the beacon frame based at least in part on information associated with the de-obfuscated TSF.

Abstract: An electronic device may transmit beacons associated with multiple access points that are cohosted by the electronic device, and that provide concurrent links in different bands of frequencies. The electronic device may include an access-point multi-link device (AP MLD). Moreover, the beacons may include: a basic service set identifier (BSSID) associated with the access points in the AP MLD, a service set identifier (SSID) associated with the access points in the AP MLD, and a MLD media access control (MAC) address associated with the access points in the AP MLD. Furthermore, a given beacon may be associated with a given access point and may include: information specifying a channel of a given link, a reduced neighbor report (RNR) providing information about at least the access points in the AP MLD, and a field that indicates when the given access point is included in the AP MLD.

Abstract: Embodiments are disclosed for group cast with retries (GCR) in a multi-link wireless communications system. In some embodiments, an access point (AP) multi-link device (MLD) can exchange information with a non-AP MLD to establish a GCR-multi-link operation (MLO) agreement corresponding to a group address, wherein the information includes, but is not limited to: a GCR primary link or a GCR primary link set of the AP MLD, an association identifier (AID) that corresponds to the group address. In some embodiments, the AP MLD can transmit a GCR frame subject to the GCR-MLO agreement, where the GCR frame includes a sequence number assigned from sequence number space (SNS)_GCR_MLO defined at a MLD level, and generate a Group Temporal Key (GTK)_GCR_ML at the MLD level, where the GTK_GCR_ML enables encryption and decryption of the GCR frame.

Abstract: An electronic device that performs a scan is described. During operation, the electronic device may perform, using a scanning radio, the scan of a band of frequencies, where the scanning radio only receives frames. Then, the electronic device may receive, using the scanning radio, a beacon associated with a second electronic device, where the beacon includes information associated with operation of a third electronic device in a second band of frequencies. Next, the electronic device may perform, using a data radio, a second scan of the second band of frequencies based at least in part on the information, where the data radio transmits and/or receives second frames, and where the second scan is performed, at least in part, while the scan is performed. Note that the electronic device may not be associated with (or may not have a connection with) the second electronic device and/or the third electronic device.

Abstract: Techniques for trigger-based transmission in a wireless network include receiving, at a first wireless device, a trigger signal including an indication of a first value for a parameter of a trigger-based physical layer protocol data unit (TB PPDU) transmission to a second wireless device, selecting, by the first wireless device, a second value for the parameter of the TB PPDU transmission, wherein the second value for the parameter is different from the first value for the parameter, and transmitting, by the first wireless device and to the second wireless device, the TB PPDU transmission using the second value for the parameter.
