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. Several other aspects of the disclosure further support this configuration and other high-bandwidth configurations.Type: ApplicationFiled: September 30, 2021Publication date: April 28, 2022Applicant: Apple Inc.Inventors: Jinjing JIANG, Yong LIU, Tianyu WU, Qi WANG, Su Khiong YONG, Jarkko L.

Patent number: 11219078Abstract: 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: GrantFiled: July 6, 2020Date of Patent: January 4, 2022Assignee: Apple Inc.Inventors: Jarkko L.

Patent number: 11160017Abstract: A dual-radio AP including both a high-power (e.g., Wi-Fi) radio and a low-power (e.g., BLE) radio may support an assisted wakeup service for a power-limited dual-radio mobile device (STA). The power-limited STA may register with the AP for the assisted wakeup service, and may then disable its Wi-Fi radio (or otherwise initiate a lower-power mode). The power-limited STA may receive a BLE communication indicating the AP has pending Wi-Fi transmissions or updates applicable to the power-limited STA. In response, the power-limited STA may turn on its Wi-Fi radio and receive the pending transmissions or updates from the AP. If an AP does not include a low-power radio, then a high-power/low-power dual-radio STA that is not power-limited may serve as an assisted wakeup service proxy. The proxy may scan and trace the Wi-Fi beacons from the AP, and generate the BLE communication to the power-limited STA on behalf of the AP.Type: GrantFiled: October 24, 2019Date of Patent: October 26, 2021Assignee: Apple Inc.Inventors: Yong Liu, Christiaan A. Hartman, Siegfried Lehmann, Su Khiong Yong, Guoqing Li
