The invention relates to a wireless telecommunication system including at least one Base Station (BS) for communicating with at least one multihop Relay Node (RN) using a wireless link of a first type and with at least one local user equipment unit (UE) located within a range of the base station (BS) using at least one wireless link of a second type, wherein the wireless link of the first type is used to transmit a combined data flow encapsulating multiple individual data flows relating to different services and/or remote user equipment (UE) units. In order to enable a global fair scheduling, the base station (BS) is further configured to receive at least one local fairness parameter from the multihop relay node (RN), said local fairness parameter representing a fairness of the distribution of radio resources of the relay node (RN) over the individual data flows in the combined data flow and to execute a global fair scheduling procedure for determining a fair distribution of available radio resources of the base station (BS) over said at least one wireless link of the first type and said at least one wireless link of the second type, wherein the local fairness parameter is used as a parameter in said global fair scheduling procedure.

A receiver is provided to receive a secondary bitstream which is transmitted by a secondary signal together with a primary signal. The receiver includes a down-converter configured to convert an input signal containing the primary and secondary signals, to a baseband complex symbol stream, A first processing unit processes the baseband complex symbol stream and provides a primary bitstream transmitted by the primary signal or a decoded primary log-likelihood ratio stream. A symbol reconstructing unit is configured to process the primary bitstream or the decoded primary log-likelihood ratio stream and to provide a reconstructed primary symbol stream. A subtraction unit is configured to provide a difference symbol stream by substracting the baseband complex symbol stream and the reconstructed primary symbol stream from each other. A second processing unit is provided to process the difference symbol stream and to provide the secondary bitstream transmitted by the secondary signal.
