Patent number: 11903027Abstract: The present disclosure relates to several techniques for reducing the occurrence of data collisions, which can occur when multiple devices simultaneously transmit data in the same (frequency) channel. For example, a turnaround time in which a device switches from a receive mode of operation to a transmit mode of operation may be reduced based on the device and another device indicating that they are capable of operating with a reduced turnaround. As another example, devices may use learning-based turnaround estimation to determine a turnaround time supported by other devices and utilize the determined turnaround time, for instance, instead of a longer turnaround time. As yet another example, multiple clear channel assessments may be performed before transmitting data. For instance, a first clear channel assessment may be performed during a backoff period, and a second clear channel assessment may be performed afterwards before data is transmitted.Type: GrantFiled: March 17, 2022Date of Patent: February 13, 2024Assignee: Apple Inc.Inventors: Sarvesh Kumar Varatharajan, Arun Vijayakumari Mahasenan, Venkateswara Rao Manepalli, Won Soo Kim, Yaranama Venkata Ramana Dass, Giri Prassad Deivasigamani, Anil G Naik, Piyush Kumar Upadhyay

Patent number: 10880379Abstract: Methods and apparatus to manage communication sessions to handover between a direct connection at a secondary wireless device and a relayed connection to the secondary wireless device via a primary wireless device. A connection manager of a secondary wireless device can trigger transfer of a communication session based on measurements of performance metrics for the communication session. Upon detection of performance degradation in a local connection or a backhaul connection or both, the connection manager of the secondary wireless device can determine proximity of and/or capabilities for connections of the primary wireless device and instigate transfer of the communication session between different connection types, such as between a direct connection and a relayed connection. The transfer of the communication session can occur without user intervention or in response to input from the user without interrupting or reestablishing the communication session.Type: GrantFiled: November 26, 2018Date of Patent: December 29, 2020Assignee: Apple Inc.Inventors: Luciano M. Verger, Ajoy K. Singh, Christopher M. Garrido, Najeeb M. Abdulrahiman, Ming Jin, Anil G. Naik, Deepak Chitlur Lakshman, Srinivasan Vasudevan, David L.

Patent number: 10855411Abstract: A source device connected to a sink device over a first wireless connection. The source device identifies a frame for retransmitting a voice packet associated with a real time application from the source device to the sink device, determines that a precedent operation is scheduled for the frame, delays the precedent operation to a subsequent frame, following the retransmitting of the voice packet and scheduling a retransmission operation for retransmitting the voice packet during the frame.Type: GrantFiled: September 7, 2018Date of Patent: December 1, 2020Assignee: Apple Inc.Inventors: Anil G.

Patent number: 9992447Abstract: This disclosure relates to inter radio access technology management for audiovisual calls. Wireless link availability and suitability for an audiovisual call may be evaluated for each of a first radio access technology and a second radio access technology. One or more wireless links on which to establish an audiovisual call may be selected based on the evaluations. The audiovisual call may be established on the selected wireless link(s). Wireless link availability and suitability for an audiovisual call may be monitored during the audiovisual call and decisions on whether to perform handover to a different wireless link and/or media duplication on multiple wireless links may be made based on the suitability for an audiovisual call of available wireless links.Type: GrantFiled: May 27, 2016Date of Patent: June 5, 2018Assignee: Apple Inc.Inventors: Ajoy K.

Patent number: 9883546Abstract: Apparatuses, systems, and methods for user equipment (UE) devices to perform a postponement of a data service request are described. A UE may detect a data service request failure during cell reselection and postpone a resend of the data service request based on a status of the cell reselection. The status may be an indication that the UE is attempting to camp on a cell or that the UE is monitoring one or more metrics associated with cell reselection. To postpone the data service request, the UE may postpone the data service request for a specified period of time or until the cell reselection is complete. The status may be monitored on a first layer of a protocol stack and the data service request may generated by a second layer of the protocol stack. The postponement may be for a fixed or variable time period.Type: GrantFiled: September 4, 2015Date of Patent: January 30, 2018Assignee: Apple Inc.Inventors: Venkateswara Rao Manepalli, Madhusudan Chaudhary, Prashant H.

Publication number: 20170318515Abstract: Embodiments are presented herein of techniques for a mobile device to control timing of inter-RAT handovers. In some embodiments, an apparatus includes one or more processing elements configured to execute an interactive wireless communication application using a wireless communication configuration between the apparatus and a communications network for a first RAT. In some embodiments, the wireless communication configuration does not have a QoS guarantee. In some embodiments, the apparatus is configured to store information from the communications network that specifies one or more wireless thresholds relating to handover from the first RAT to a second RAT. In some embodiments, based on executing the application and current wireless conditions, the apparatus is configured to send a report to a base station of the communications network, prior to at least one of the thresholds being met, to trigger a handover from the first RAT to the second RAT.Type: ApplicationFiled: April 29, 2016Publication date: November 2, 2017Inventors: Sunny Arora, Anil G.

Patent number: 9706448Abstract: A voice over Long Term Evolution (VoLTE) capable mobile device is configured to deregister from an Internet Protocol (IP) Multimedia Subsystem (IMS) network element for voice connections and use a dual network mode of operation that includes data connections via a 4G LTE/LTE-A network and voice connections via a legacy 3G or 2G network based on performance metrics a serving cell of the 4G LTE/LTE-A network. When the performance metrics indicate that voice connections may be unstable, such as when a reference signal received power (RSRP) falls below a threshold level but remains above a reselection/handover threshold level, the mobile device deregisters from the IMS network element to disable VoLTE connections from being established. The mobile device establishes the requested voice connection via a legacy 3G or 2G network instead, while established or new data connections for the mobile device continue to use the 4G LTE/LTE-A network.Type: GrantFiled: May 29, 2015Date of Patent: July 11, 2017Assignee: Apple Inc.Inventors: Anil G.
