Abstract

There is provided mechanisms for frequency selective scheduling of wireless devices in a communication network. A method is performed by a wireless network node. The method comprises transmitting a first packet to at least one wireless device over the entire available bandwidth of the communication network, wherein the first packet comprises information identifying which wireless devices are addressed by the packet, and which downlink sub-carriers are used for data transmission to the addressed wireless devices. The method comprises receiving a second packet on uplink sub-carriers allocated to at least the addressed wireless devices and therefrom determining channel quality indications for the uplink sub-carriers. The uplink sub-carriers are allocated to enable the channel quality indications to be determined over the entire bandwidth for at least each one of the addressed wireless devices.
