Abstract
A method of controlling transmission of an upstream packet traffic from a plurality of Optical Network Units to an Optical Line Terminal in a Passive Optical Network based fronthaul network. The Optical Network Units transmit packets in a time division multiplexed access scheme to the Optical Line Terminal and the method comprises obtaining mobile upstream scheduling information, scheduling the packet traffic from the plurality of Optical Network Units based on delay constraints of the PON-based front haul network and the obtained mobile upstream scheduling information. The method also comprises transmitting the scheduling of the packet traffic to the plurality of ONUs.
