Abstract: Some aspects include apparatuses and methods for implementing a target wake time (TWT) scheme (or technique) for multi-link wireless communication networks. For example, a multi-link device (MILD) includes a first station (STA) associated with a first link of a wireless network and configured to communicate with a second MLD over the first link using a multi-link target wake time (TWT) process. The MLD also includes a second STA associated with a second link of the wireless network and configured to communicate with the second MLD over the second link using the multi-link TWT process. The MLD further includes one or more processors communicatively coupled to the first and second STAs and configured to control the operations of the first and second STAs to perform the multi-link TWT process.

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: 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.

Abstract: Some aspects of this disclosure include apparatuses and methods for implementing a hibernation mode for multi-link wireless communication networks such as a wireless local area network (WLAN). For example, some aspects relate to a multi-link device (MLD) including a first station (STA) associated with a first link of a wireless network and configured to communicate with a second MLD over the first link. The MLD also includes a second STA associated with a second link of the wireless network. The second STA is in a hibernation mode. The MLD also includes one or more processors communicatively coupled to the first and second STAs and configured to control operations of the first and second STAs.

Abstract: Examples of the disclosure are directed to micro-machined ultrasonic transducers (MUTs) which can be embedded into a flexible band of a watch to detect touch, gestures, physiological signals, and transfer data. In some examples, the MUTs can include a piezoelectric material disposed between two electrodes and coupled to a base material having a plurality of cavities, to support motion of the transducer structure. In some examples, the MUTs can be coupled to multiplexing circuitry to stimulate, configure and control the MUTs. In some examples, the size, shape, and arrangement of transducers can be changed to improve characteristics associated with ultrasonic transmission. In some examples, the MUT array can be driven (e.g., by the CMOS circuitry) to beamform the transmitted and/or the received ultrasonic waves. In some examples, the one or more MUT arrays can be configured to generate haptic feedback via the flexible band.

Abstract: Some aspects of this disclosure include apparatuses and methods for implementing backup link establishment and operation for multi-link wireless communication networks such as a wireless local area network (WLAN). Some aspects relate to an electronic device including a transceiver configured to communicate over a wireless network and a processor communicatively coupled to the transceiver. The processor receives a message including information associated with a backup link from a second electronic device. The processor further receives data associated with data traffic from the second electronic device on a primary link of the wireless network. In response to a quality of the primary link being below a threshold, the processor receives a notification frame from the second electronic device on the backup link and receives additional data associated with the data traffic from the second electronic device on the backup link or on an other link informed by the notification frame.

Abstract: Some embodiments include an apparatus, method, and computer program product for Extremely High Throughput (EHT) medium reservation. Some embodiments include a first station configured to exchange EHT-Request to Send (RTS) and/or EHT-Clear to Send (CTS) capabilities with a second station, and determine CTS response mode (e.g., rules) for the first station based at least on the RTS and CTS capabilities of the first and the second stations. Some embodiments include transmitting RTS frames and receiving CTS frames in the presence of punctured channels, implementing a flexible channel reservation scheme, reserving punctured bandwidths, and receiving CTS frames even when a primary channel is busy. Some embodiments include an RTS or an CTS frame that includes an EHT bandwidth puncture (BnP) signaling address and/or a modified scrambler seed that enable channel reservations for an EHT bandwidth.
