Abstract:
Embodiments relate to apparatuses ( 10; 20 ), methods and computer programs for determining transmission control information. The Apparatus ( 10 ) is suitable for a base band unit ( 110 ) of a base station transceiver ( 100 ) of a mobile communication system ( 300 ), the base station transceiver ( 100 ) further comprising one or more radio units ( 120 ) configured to wirelessly communicate with the base band unit ( 110 ) using one or more wireless fronthaul links. The apparatus ( 10 ) comprises at least one output ( 12 ) configured to transmit a downlink component of the one or more wireless fronthaul links to the one or more radio units ( 120 ). The apparatus ( 10 ) further comprises at least one input ( 14 ) configured to receive an uplink component of the one or more wireless fronthaul links from the one or more radio units ( 120 ). The apparatus ( 10 ) further comprises a control module ( 16 ) configured to control the at least one output ( 12 ) and the at least one input ( 14 ). The control module ( 16 ) is further configured to transmit a reference signal via the at least one output ( 12 ) to the one or more radio units ( 120 ). The control module ( 16 ) is further configured to receive a loopback version of the reference signal via the at least one input ( 14 ) from the one or more radio units ( 120 ). The control module ( 16 ) is further configured to determine transmission control information based on an attenuation of the reference signal determined based on the loopback version of the reference signal. The transmission control information comprises information related to a per-radio unit transmission power to be used by the one or more radio units ( 120 ) for transmissions on the one or more wireless fronthaul links. The control module ( 16 ) is further configured to provide the transmission control information to the one or more radio units ( 120 ) via the at least one output ( 12 ).

Claim (Index 3):
The apparatus of  claim 2 , wherein the control module is configured to determine the per-radio unit transmission power based on an optimization function, wherein the control module is configured to determine the per-radio unit transmission power such, that a target Signal-to-Interference and Noise, SINR, for the uplink component is approximated based on SINR target , u = P tx c i - PL u i \ue89e - P IF , z , NF wherein SINR target,u  is the target SINR for the uplink component, P tx c i \u2003is the per-radio unit transmission power of a radio unit i of the one or more radio units, PL u i  is an estimated path loss of the uplink component of the radio unit i, and P IF,z,NF  is based on an interference power, IF, a thermal noise, z, and a receive noise figure, NF, of the uplink component.
