A method is proposed for selecting an allocation group comprising an ordered succession of radio resources from a first radio resource to a last radio resource, iterating the following operations: selecting the last radio resource of the allocation group, each last radio resource taking, at each iteration, a position in the ordered succession lower than the position taken in the ordered succession by the last radio resource at the respective previous iteration, estimating a signal to interference-plus-noise ratio per radio resource of the allocation group according to a number of radio resources of the allocation group, from the first to the last radio resources of the allocation group, and according to history transmissions information, and until the signal to interference-plus-noise ratio per radio resource is higher than a predetermined signal to interference-plus-noise ratio, allocating the radio resources from said first to said last radio resources of the allocation group.
