Abstract
A method for time-domain allocation of radio resources in a communication system using beamforming comprises obtaining of a list of wireless devices to be served. Subcarriers and beam directions of a multi-directional beamform are allocated to wireless devices of the list. The beam direction for each wireless device covers a position of that wireless device. The number of allocable subcarriers is limited to fulfil a beam-forming power constraint. This beam-forming power constraint is that the total power of allocated subcarriers, when each allocated subcarrier provides a same effective isotropic radiated power density for a wireless device as would be provided by a single-directional beamform, is within a predetermined power budget.
