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
