    • 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).

    • It is described a method for transmitting data within a mobile telecommunication system (100) from a user equipment (110) having at least two transmit antennas (115) to a base station (150) having at least two receive antennas (155). The method comprises (a) providing a number of data streams at the user equipment (110), wherein the number of data streams is smaller than or equal to the number of transmit antennas (115), (b) applying a spatial pre-coding (122) to the data streams, and (c) transmitting the spatially pre-coded data streams to the base station (150) via the transmit antennas (115), wherein the number of transmit antennas (115) used for transmitting the spatially pre-coded data streams is larger than the number of data streams. It is further described a corresponding method for receiving data, a user equipment (110) for carrying out the data transmitting method, a base station (150) for carrying out the data receiving method and a computer program for controlling the described data transmitting and/or receiving method.
