A method of scheduling transmissions to client devices comprises receiving feedback (f1a-f3d) about a plurality of candidate downlink frequency resources (91-94) from a plurality of client devices and/or measuring channel qualities of a plurality of candidate uplink frequency resources (95-98) from receptions of transmissions, e.g. of the feedback, by the plurality of client devices. The method further comprises selecting a subset (92) of the plurality of candidate downlink frequency resources and/or a subset (96) of the plurality of the candidate uplink frequency resources based on the received feedback and/or the measured channel qualities. The method further comprises scheduling transmissions (dd1-3) to the client devices on the selected subset of candidate downlink frequency resources and/or transmissions (ud1-3) from the client devices on the selected subset of uplink frequency resources.
