A method for performing in an access node time- and frequency scheduling for a cell comprising two or more subcells, the method comprising: selecting a set of one or more active beams for each of at least two subcells comprised in the two or more subcells from beams produced by an antenna array of the access node, wherein the selecting the set of one or more active beams for each of the at least two of subcells comprises: receiving radio channel measurements of terminal devices within the cell; determining for each terminal device in the cell a preferred beam from the beams based on the radio channel measurements, the preferred beam providing best channel quality for the terminal device; mapping each of the beams produced by the antenna array to one of the subcells based on preferred beams of the terminal devices in different subcells and a load balancing scheme; and selecting the set of one or more active beams for each of the at least two of subcells from mapped beams of a corresponding subcell such that all beams comprised in selected sets of one or more active beams are substantially spatially orthogonal at least for terminal devices with highest scheduling priority in each of the at least two subcells; performing (402, 505) time-scheduling for the cell in common; and performing (403, 506) frequency-scheduling separately and in parallel for each of the at least two subcells for transmission using a corresponding set of one or more active beams. selecting a set of one or more active beams for each of at least two subcells comprised in the two or more subcells from beams produced by an antenna array of the access node, wherein the selecting the set of one or more active beams for each of the at least two of subcells comprises: receiving radio channel measurements of terminal devices within the cell; determining for each terminal device in the cell a preferred beam from the beams based on the radio channel measurements, the preferred beam providing best channel quality for the terminal device; mapping each of the beams produced by the antenna array to one of the subcells based on preferred beams of the terminal devices in different subcells and a load balancing scheme; and selecting the set of one or more active beams for each of the at least two of subcells from mapped beams of a corresponding subcell such that all beams comprised in selected sets of one or more active beams are substantially spatially orthogonal at least for terminal devices with highest scheduling priority in each of the at least two subcells; receiving radio channel measurements of terminal devices within the cell; determining for each terminal device in the cell a preferred beam from the beams based on the radio channel measurements, the preferred beam providing best channel quality for the terminal device; mapping each of the beams produced by the antenna array to one of the subcells based on preferred beams of the terminal devices in different subcells and a load balancing scheme; and selecting the set of one or more active beams for each of the at least two of subcells from mapped beams of a corresponding subcell such that all beams comprised in selected sets of one or more active beams are substantially spatially orthogonal at least for terminal devices with highest scheduling priority in each of the at least two subcells; performing (402, 505) time-scheduling for the cell in common; and performing (403, 506) frequency-scheduling separately and in parallel for each of the at least two subcells for transmission using a corresponding set of one or more active beams.
