1. A method for frequency selective scheduling of wireless devices in a communication network, the method being performed by a wireless network node, comprising the steps of:

  • transmitting a first packet to at least one wireless device over the entire available bandwidth of the communication network, wherein said first packet comprises information identifying which wireless devices are addressed by the first packet, and which downlink sub-carriers are used for data transmission to said addressed wireless devices; and

    receiving a second packet on uplink sub-carriers allocated to at least said addressed wireless devices and therefrom determining channel quality indications for said uplink sub-carriers, wherein said uplink sub-carriers are allocated to enable said channel quality indications to be determined over said entire bandwidth for at least each one of said addressed wireless devices by at least one of interpolating and extrapolating channel quality indications for at least two uplink sub-carriers, and wherein said uplink sub-carriers for each one of said wireless devices are determined to be frequency interleaved.
