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.

Method and apparatus for controlling transmission of an upstream packet traffic in a TDM PON-based fronthaul

A method () of over-the-air testing of a transmission equipment (). The method comprises transmitting () a transmission signal from the transmission equipment. The transmission signal as transmitted comprises emissions in an in-band domain () and emissions in an unwanted domain (). The method comprises arranging a frequency selective surface () to receive the transmission signal. The frequency selective surface () attenuates the transmission signal in the in-band domain () of the transmission signal. The frequency selective surface () allows propagation of the transmission signal in the unwanted domain () of the transmission signal. The method further comprises measuring () in a measuring equipment () a parameter of the transmission signal in the unwanted domain. The frequency selective surface () is arranged between the transmission equipment () and the measuring equipment ().
