Facilitating time synchronization functionality at user equipment

A method of wireless communication at a first device, comprising:

• transmitting, to a second device, capability information indicating that the first device is capable of operating as a precision time protocol (PTP) grand master clock;
• receiving, from the second device, one or more PTP parameters based on the capability information indicating that the first device is capable of operating as a PTP grand master clock;
• generating, based on the one or more PTP parameters received from the second device, a first PTP message including time information;
• and
• transmitting the first PTP message including the time information to one or more downstream devices in communication with the first device.

An apparatus for wireless communication, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive, from a first device, capability information indicating that the first device is capable of operating as a precision time protocol (PTP) grand master clock;
• transmit, based on the received capability information, one or more PTP parameters to the first device;
• and
• transmit, to the first device, an activation message to enable the first device to transmit, based on the one or more PTP parameters, PTP messages to one or more downstream devices in communication with the first device, the PTP messages including time information.
