Synchronization estimation based on ultra-wideband connections

A method comprising:

• receiving, at a device, a clock synchronization request from a remote device, the request being received over a wireless communication link;
• generating, by a controller associated with a firmware layer of the device, a response to the synchronization request, the response being configured for synchronizing a remote clock of the remote device and a local clock of the device;
• and
• sending, to the remote device, the response to the synchronization request, the controller of the firmware layer configured for generating the response without accessing an application processor (AP) of the device.

One or more processors configured for wireless communication by performing operations comprising:

• receiving, for a device, a clock synchronization request from a remote device, the request being received over a wireless communication link;
• generating, for a firmware layer of the device, a response to the synchronization request, the response being configured for synchronizing a remote clock of the remote device and a local clock of the device;
• and
• sending, to the remote device, the response to the synchronization request without accessing an application processor (AP) of the device.
