Abstract: A method and base station (600) of a first cell (602), for—controlling inter-Gail interference in a cellular network when Discontinuous Reception, DRX, is applied for User Equipments, UEs. The base station selects a DRX scheme with active periods that are separated in time from active periods of a DRX scheme used for UEs in DRX mode in a neighbouring second cell (806). The selected DRX scheme is then used for a first UE (604) in DRX mode in the first cell to avoid interference between transmissions of signals in the active periods to the first UE in the first cell and transmissions of signals in active periods to the UEs in the neighbouring second cell.

Abstract: Method and arrangement in a network entity for supporting link adaptation in a wireless communication system. The method comprises obtaining 204 one or more predicted parameters related to the quality of a radio link. The method further comprises measuring 206 one or more actual parameters, corresponding to the one or more predicted parameters. The method further comprises deriving 208 one or more error distributions based on the difference between the predicted and actual one or more parameters, from which error distributions a link adaptation margin estimate is derived, based on a predetermined radio link quality target. The link adaptation margin estimate is then used for supporting link adaptation for the radio link.
