Abstract: Some embodiments include utilizing a multilink media access control (MAC) address structure to support multilink devices (MLDs) that can operate concurrently in more than one link such as extremely high throughput (EHT) access points (APs) and EHT stations (STA), where the multilink MAC address structure is compatible with legacy devices. An EHT AP can utilize a multilink basic service set (BSS) identification (BSSID) MAC address to communicate with an EHT STA identified by a multilink MAC address. Values of the multilink BSSID and the multilink MAC address of the EHT STA are independent of which of the multiple links are used in the communication. In addition, to utilizing a multilink BSSID, the EHT AP can also support unique link-specific MAC addresses to concurrently support legacy and MLD stations. The EHT STA can also utilize unique link-specific MAC addresses that can be different than the EHT AP's link-specific MAC addresses.

Abstract: Methods, systems and apparatuses for performing an address change by an access point (AP) multi-link device (MLD) and non-AP MLD are described. A non-AP MLD may transmit to an AP MLD, using one or more respective transmission (TX) links in an active mode, one or more uplink frames that include one or more respective initial addresses corresponding to one or more respective reception (RX) links of the AP MLD. The non-AP MLD may then configure the one or more respective TX links to a lower power mode. The non-AP MLD may configure the one or more respective TX links with one or more respective new addresses prior to transitioning the one or more respective TX links back to the active mode. The non-AP MLD may transmit, to the AP MLD, one or more additional uplink frames that include the one or more respective new addresses.

Abstract: One or more wireless stations operate to configure direct communication with neighboring mobile stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. A wireless station may enter an unsynchronized discovery mode, transmit, in response to receiving a subscribe message from a neighboring device, a publish message to the neighboring device, perform authentication and trusted device cluster provisioning with the neighboring wireless device, and protect transmissions using the security credentials. In the unsynchronized discovery mode, the wireless device may monitor a discovery channel for subscribe messages, e.g., from neighboring peer devices. Additionally, the trusted device cluster provisioning may provide security credentials to the wireless device. Note that protecting transmissions using the security credentials may include protecting a trusted device cluster identity, transmitted beacons, transmitted management frames, or transmitted action frames using the security credentials acquired via the trusted device cluster provisioning.

Abstract: An interface circuit in an electronic device may contend for access to a shared communication channel on behalf of the electronic device and a recipient electronic device, where the access has a duration. Then, the electronic device may provide a schedule frame intended for the recipient electronic device that includes information that specifies one or more time slots during the duration that are associated with the recipient electronic device and one or more communication functions of the recipient electronic device in the one or more time slots. Moreover, the electronic device may provide a data frame with data intended for the recipient electronic device. In response, the electronic device may receive a response frame associated with the recipient electronic device, where the response frame is received during at least one of the one or more time slots.

Abstract: Various embodiments for service constraint advertisement and discovery are provided. Each wireless device in a group of wireless devices can multicast a service advertisement frame to advertise a service provided, a discovery request frame to request for a service, a discovery response frame in response of a discovery request frame if the wireless device can provide the requested service, or a discovery proxy response frame in response of a discovery request frame if another wireless device can provide the requested service. The frames include information related to one or more services and capabilities, availability schedule, frequency band in use, and other information. This allows a new device joining the group to accomplish device discovery and service discovery at the same time. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract: Embodiments herein provide systems, apparatuses, and methods for authentication of an access point and a station in a wireless local area network. An access point and station may generate a Key Encryption Key (KEK). The access point and station may send authentication credentials encrypted based on the KEK. The access point may authenticate the station by validating the station authentication credential, and the station may authenticate the access point by validating the access point authentication credential.

Abstract: A method and apparatus for synchronizing a timebase is disclosed. A timebase management circuit includes limit circuitry, in a first clock domain, which generates, based on a global timebase, an initial timebase limit. The timebase management circuit includes, in a second clock domain, adjustment circuitry that generates an adjusted timebase limit based on the initial timebase limit. A storage circuit in the second clock domain stores a local timebase. Update circuitry, coupled to an output of the storage circuit, generates an updated local timebase using a clock signal in the second clock domain, wherein the updated local timebase is subject to the adjusted timebase limit.

Abstract: Some embodiments of this disclosure include apparatuses and methods for implementing a target wake time (TWT) scheme that includes traffic differentiation and service period extension. For example some embodiments relate to an electronic device including a transceiver and one or more processors communicatively coupled to the transceiver. The one or more processors receive an indication of traffic associated with an application. The one or more processors determine information associated with the traffic and configure the TWT scheme associated with the traffic based at least in part on the determined information. The one or more processors further communicate initial information associated with the TWT scheme to an access point of a wireless network. The initial information associated with the TWT scheme can include at least one of traffic direction information, traffic pattern information, a traffic identifier (TID), or an access category, indication (ACID).

Abstract: An apparatus for time management of a peripheral device is disclosed. A peripheral interface circuit receives information from a host circuit over a peripheral bus, the host circuit maintaining a global timebase in accordance with a first clock signal within a first clock domain. The peripheral interface circuit maintains, based om a second clock signal within a second clock domain, a first local timebase correlated to the global timebase. A peripheral control circuit operates in a third clock domain and maintains a second local timebase based on the first. The peripheral interface circuit determines phase and frequency differences between the second and third clock signals in determining a correlation between the second and first local timebases. A peripheral logic circuit in the third clock domain performs, operations that utilize a timestamp from the second local timebase, which accounts for correlation with the first local timebase.

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.
