1. A method for time-domain allocation of radio resources in a communication system using beamforming, said method comprising:
obtaining a list of wireless devices to be served;
allocating subcarriers as allocable subcarriers and a respective beam direction from beam directions of a multi-directional beamform to each wireless device of said list;
wherein said respective beam direction for each wireless device covers a position of that wireless device;
wherein a number of the allocable subcarriers is limited to fulfil a beam-forming power constraint; and
wherein said beam-forming power constraint is set so that a total power of the allocable subcarriers is within a predetermined power budget, based on each allocable subcarrier providing a same effective isotropic radiated power (EIRP) density for a respective wireless device in the respective direction of the multi-directional beamform as would be provided to the respective wireless device if by a single-directional beamform.
