Abstract
An Open Radio Access Network (O-RAN) includes: an O-RAN Radio Unit (O-RU) configured to transmit radio signals to user equipment; an O-RAN Distributed Unit (O-DU) configured to perform baseband processing; and a fronthaul network, wherein the O-RU and the O-DU are nodes of the fronthaul network, and wherein the O-RU and the O-DU are configured to communicate over the fronthaul network; wherein the O-DU is configured to transmit a one-way delay measurement message to the O-RU on the fronthaul network, wherein the one-way delay measurement message includes a value that is based on a hardware time stamp that was inserted immediately prior to transmission of the one-way delay measurement message; and wherein the O-RU is configured to transmit a response to the one-way delay measurement message to the O-DU, wherein the response includes a second value that is based on a second hardware time stamp generated when the O-RU received the one-way delay measurement message from the fronthaul network.
