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. Kneckt, Gaurav Jain, Yong Liu, Jinjing Jiang, Tianyu Wu, Su Khiong Yong, Guoqing Li, Charles F. Dominguez

Patent number: 10838893Abstract: An electronic device may include an applications processor that communicates with a peripheral input-output (I/O) device using a coprocessor. The applications processor may include a first interprocessor communications (IPC) module, whereas the coprocessor may include a second IPC module for interfacing with the first IPC module. The first IPC module may forward a group of transactions to a submission queue and may ring a submission doorbell interrupt to signal that work items are pending in the submission queue. In response, the second IPC module may dequeue the work items from the submission queue and process these items at the I/O device. The second IPC module may provide a group of completed transactions to a completion queue and may ring a completion doorbell interrupt to signal that items are pending in the completion queue. Thereafter, the completed items are forwarded to other parts of the applications processor for processing.Type: GrantFiled: September 2, 2014Date of Patent: November 17, 2020Assignee: Apple Inc.Inventors: Charles F. Dominguez, Ashima Kapur, Kiran Kattel

Publication number: 20200137612Abstract: 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).Type: ApplicationFiled: August 29, 2019Publication date: April 30, 2020Applicant: Apple Inc.Inventors: Guoqing Li, Yang Yu, Welly Kasten, Shehla S.

Patent number: 9661558Abstract: 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.Type: GrantFiled: December 18, 2012Date of Patent: May 23, 2017Assignee: Apple Inc.Inventor: Charles F.

Patent number: 9491607Abstract: An electronic device performs a scan of each wireless channel in a sequence of wireless channels to detect advertising frames transmitted from other electronic devices. When performing the scan, the electronic device waits for a next transmit time. After the next transmit time, the electronic device configures the electronic device to monitor a next wireless channel from the sequence of wireless channels. The electronic device then monitors the next wireless channel for the advertising frames for a scanning time interval, wherein a duration of the scanning time interval is set in accordance with one or more transmit times used for transmitting advertising frames on the wireless channels in the sequence of wireless channels. When wireless channels from the sequence of wireless channels remain to be scanned, the electronic device returns to wait for a next transmit time.Type: GrantFiled: February 16, 2012Date of Patent: November 8, 2016Assignee: Apple Inc.Inventors: Pierre B.
