This application is a continuation application of U.S. application Ser. No. 17/342,937 entitled “Managing Transmit Timing Of Data Transmissions,” filed on Jun. 9, 2021, the entire contents of which is hereby incorporated by reference for all purposes.
Long Term Evolution (LTE), 5G new radio (NR) (5GNR), and other recently developed communication technologies allow wireless devices to communicate information at data rates (e.g., in terms of Gigabits per second, etc.) that are orders of magnitude greater than what was available just a few years ago. These and other recent improvements have facilitated the emergence of the Internet of Things (IoT), large scale Machine to Machine (M2M) communication systems, autonomous vehicles, and other technologies that enable a network element (e.g., a server) to receive data transmissions from a plurality of wireless devices (e.g., mobile phones, sensors, etc.).
