Publication number: 20220201785Abstract: 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.Type: ApplicationFiled: January 3, 2022Publication date: June 23, 2022Applicant: Apple Inc.Inventors: Jarkko L.

Publication number: 20220132481Abstract: Methods and apparatuses are disclosed for high-bandwidth stations in a WiFi environment. In embodiments, a bandwidth of communications supported by the access point is divided into multiple frequency segments. In an embodiment, bandwidths up to 320 MHz are supported, which can be subdivided into four frequency segments of 80 MHz each. Different stations park on different frequency segments, whereas the access point has its primary channel located on the first frequency segment. With this configuration, uplink and downlink channel access can be provided to the different stations using a primary channel hopping pattern, which is provided to the stations from the AP. This pattern provides time windows for each frequency segment, during which the stations in that segment are able to freely communicate.
