A method (200) is proposed for allocating, in a wireless communications network (100), radio resources (PRBk) for uplink transmissions. The method comprises: selecting (205), among said radio resources (PRBk), an allocation group (AG (i) ) comprising an ordered succession of radio resources available for allocation from a first radio resource (PRBF) to a last radio resource (PRBL (i) ), iterating the following operations: selecting (225) the last radio resource (PRBL(i)) of the allocation group (AG (i) ), each last radio resource (PRBL(i)) taking, at each iteration, a position (P L(O) ) in the ordered succession lower than the position taken in the ordered succession by the last radio resource (PRB L(i) ) at the respective previous iteration, estimating (210,215) a signal to interference-plus-noise ratio per radio resource (SINRPRB(i)) of the allocation group (AG (i) ) according to a number of radio resources (Q(ij) of the allocation group (AG(ij), from the first (PRB F ) to the last (PRB L(i) ) radio resources of the allocation group (AG (i) ), and according to history transmissions information, and until (220) the signal to interference-plus-noise ratio per radio resource (SINR PRB(i) ) is higher than a predetermined signal to interference-plus-noise ratio (SINR TH ), allocating (240,255) the radio resources from said first (PRB F ) to said last (PRBL(i)) radio resources of the allocation group (AG (i) ). |
