Abstract: A camera may include a substrate for placing components. An image sensor having a light-receiving side and an opposite non-light-receiving side may be attached to a first side of the substrate to receive light from one or more lenses of the camera to capture an image. The camera may also include one or more additional components separate and distinct from the image sensor. The additional components may be placed beneath the non-light-receiving side of the image sensor. The components may be attached to a second side of the substrate opposite the first side where the image sensor is mounted at least partially inside one or more recesses, or embedded at least partially inside the substrate.

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 communicates frames is described. During operation, the electronic device may transmit the frames addressed to a recipient electronic device and associated with multiple links between the electronic device and the recipient electronic device. Then, the electronic device may receive block acknowledgments for at least a subset of the frames, where a given block acknowledgment is associated with the recipient electronic device and indicates received frames on a given link in the links. Moreover, the electronic device may control an amount of traffic conveyed on the links based at least in part on the block acknowledgments. Next, the electronic device may store a remainder of the frames based at least in part on the block acknowledgments, where the frames include the subset of the frames and the remainder of the frames. Note that the frames may have a common traffic identifier.

Abstract: This disclosure relates to methods for multi-access point association in a wireless local area network. Multiple access point wireless devices may establish a multi-access point system. Other access point wireless devices may subsequently join the multi-access point system. Non-access point wireless devices may form an association with the multi-access point system, which may include links with multiple different access point wireless devices in the multi-access point system.

Abstract: Techniques are disclosed for obfuscation in a privacy beacon. An example method includes a first communication device creating a beacon field to be included in a beacon frame. The first communication device can generate a timing synchronization field to be included in the beacon frame. The first communication device can apply an offset to the timing synchronization field of the beacon frame. The first communication device can transmit the beacon frame to a second communication device, the beacon frame comprising the offset timing synchronization field and the beacon field.

Abstract: A method for communicating over a wireless network includes broadcasting, by a Multi-Link Device (MLD) device, service data indicative of one or more services for wireless communication with a client device; wherein the service data indicates that a service type is differentiated based on a type of the client device; establishing a security association with the client device; and in response to establishing a security association with the client device, granting access by the client device to a subset of the one or more services based on the type of the client device.

Abstract: An electronic device (such as an access point) that receives one or more block acknowledgments is described. This electronic device may transmit an extremely high-throughput (EHT) physical layer convergence protocol (PLCP) protocol data unit (PPDU) to a recipient electronic device, where the EHT PPDU is transmitted in multiple non-contiguous sub-bands that are separated by a punctured sub-band. Moreover, the electronic may receive the one or more block acknowledgments from the recipient electronic device, where the one or more block acknowledgments exclude the punctured sub-band. Note that the EHT PPDU may exclude transmitted energy in the punctured sub-band. Moreover, the punctured sub-band may have a bandwidth of at least 20 MHz and may be different from a primary sub-band.

Abstract: Methods, systems and apparatuses for managing enhanced multi-link single radio operation by an access point (AP) multi-link device (MLD) and non-AP MLD are described. A non-AP MLD may exchange parameters with an AP MLD. The non-AP MLD may request suspension of a multi-link single radio operation.

Abstract: A first multilink device (MLD) is configured to communicate with a second MLD using at least two communication links. The first MLD selects a first link of the at least two communication links for communications between the first MLD and the second MLD, detects that the first link is unavailable for communications, switches a radio of the first MLD to a second link of the at least two communication links, transmits an alert to the second MLD regarding the switching from the first one of the at least two communication links to the second one of the at least two communication links and communicates with the second MLD via the second link.
