Claim of US Patent No. 10,172,147

1. A method for allocating, in a wireless communications network, radio resources for uplink transmissions, the method comprising:selecting, among said radio resources, an allocation group comprising an ordered succession of radio resources available for allocation from a first radio resource to a last radio resource; and
iteratively performing:
selection of the last radio resource of the allocation group, each last radio resource taking, at each iteration, a position in the ordered succession lower than a position taken in the ordered succession by the last radio resource of an immediately previous iteration,
estimation of 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, the estimation of the signal to interference-plus-noise ratio including multiplying the signal to interference-plus-noise ratio by a scaling factor that is based on a number of radio resources in the allocation group, and
until the signal to interference-plus-noise ratio per radio resource is higher than a predetermined signal to interference-plus-noise ratio, allocation of the radio resources from said first to said last radio resources of the allocation group.
