    • A method and a system for transmitting data by a transmitter over a channel having a predetermined channel quality estimate, comprises the steps of splitting (S2P) input data stream (S40, S60, S80) to be transmitted into a plurality of data sub-streams (S40a, S40b, S40c); processing (SYM1, SYM2, SYMj) each of the plurality of data sub-streams (S40a, S40b, S40c) into a plurality of symbol subsets (S41, S42, S43) by selecting a certain scheme of coded-modulation (BPSK, QPSK, 16-QAM); processing, separately, each of the plurality of symbol subsets (S41, S42, S43), via a plurality of separate Discrete Fourier Transforms (DFT1, DFT2, DFT3), herein after denoted as DFTs, to obtain a plurality of DFT-precoded data sub-streams (S44, S45, S46); allocating each DFT-precoded data sub-stream (S44, S45, S46) in a frequency resource block (RB1, RB2, RB3), via a sub-carrier mapping module (SCM), so that for each data sub-stream (S40a, S40b, S40c) the selected scheme of coded-modulation (BPSK, QPSK, 16-QAM) is chosen in dependence of the values of the channel quality estimate at the frequencies of its own allocated frequency resource block (RB1, RB2, RB3).

    • 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 (10) 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 (12) of a second type, wherein the wireless link (10) 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 (10) of the first type and said at least one wireless link (12) of the second type, wherein the local fairness parameter is used as a parameter in said global fair scheduling procedure.
