Abstract

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 …
