A system for scheduling transmissions to client devices, comprising: at least one receiver; and at least one processor configured to: - use said at least one receiver to receive feedback about a plurality of candidate downlink frequency resources from a plurality of client devices and/or measure channel qualities of a plurality of candidate uplink frequency resources from receptions of transmissions by said plurality of client devices, - select a subset of said plurality of candidate downlink frequency resources and/or a subset of said plurality of candidate uplink frequency resources based on said received feedback and/or said measured channel qualities, and - schedule transmissions to said plurality of client devices on said selected subset of candidate downlink frequency resources and/or transmissions from said plurality of client devices on said selected subset of uplink frequency resources, characterized in that at least one of said plurality of candidate downlink frequency resources is paired with at least one of said plurality of candidate uplink frequency resources and said at least one processor is configured to determine at least one combined quality for at least one pair of candidate downlink and uplink frequency resources and select a subset of said plurality of candidate downlink frequency resources and a subset of said plurality of candidate uplink frequency resources based on said at least one combined quality. at least one receiver; and at least one processor configured to: - use said at least one receiver to receive feedback about a plurality of candidate downlink frequency resources from a plurality of client devices and/or measure channel qualities of a plurality of candidate uplink frequency resources from receptions of transmissions by said plurality of client devices, - select a subset of said plurality of candidate downlink frequency resources and/or a subset of said plurality of candidate uplink frequency resources based on said received feedback and/or said measured channel qualities, and - schedule transmissions to said plurality of client devices on said selected subset of candidate downlink frequency resources and/or transmissions from said plurality of client devices on said selected subset of uplink frequency resources, characterized in that at least one of said plurality of candidate downlink frequency resources is paired with at least one of said plurality of candidate uplink frequency resources and said at least one processor is configured to determine at least one combined quality for at least one pair of candidate downlink and uplink frequency resources and select a subset of said plurality of candidate downlink frequency resources and a subset of said plurality of candidate uplink frequency resources based on said at least one combined quality. - use said at least one receiver to receive feedback about a plurality of candidate downlink frequency resources from a plurality of client devices and/or measure channel qualities of a plurality of candidate uplink frequency resources from receptions of transmissions by said plurality of client devices, - select a subset of said plurality of candidate downlink frequency resources and/or a subset of said plurality of candidate uplink frequency resources based on said received feedback and/or said measured channel qualities, and - schedule transmissions to said plurality of client devices on said selected subset of candidate downlink frequency resources and/or transmissions from said plurality of client devices on said selected subset of uplink frequency resources, characterized in that at least one of said plurality of candidate downlink frequency resources is paired with at least one of said plurality of candidate uplink frequency resources and said at least one processor is configured to determine at least one combined quality for at least one pair of candidate downlink and uplink frequency resources and select a subset of said plurality of candidate downlink frequency resources and a subset of said plurality of candidate uplink frequency resources based on said at least one combined quality.
