摘要： 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.

摘要： 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.

摘要： 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.

摘要： An electronic device receives a request for access to the infrastructure network (and, more generally, a ‘resource’) from the other electronic device via a peer-to-peer link. In response to the request, the electronic device determines that it has access to the infrastructure network, and provides a response to the other electronic device via the peer-to-peer link indicating that the electronic device has access to the infrastructure network. Then, the electronic device establishes secure communication with the other electronic device, and provides access information to the other electronic device via the peer-to-peer link using the secure communication. This access information facilitates access to the infrastructure network.

摘要： 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.

摘要： 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.
