According to the invention a method is provided for a link adaptation for a transmission of data from a sender to a receiver through a communication channel to a variation of a transmission condition of said communication channel. The method comprises the steps of ascertaining at least one current value of at least a first quantity indicative of said transmission condition, comparing said current value with a first target value of said first quantity, modifying the ratio between said first target value and said current value of said first quantity in dependence on the result of said comparing step, and selecting a modulation and coding scheme for said data transmission from a predetermined number of modulation and coding schemes in dependence on the result of said comparing step and on the result of said modifying step. According to the method of the invention, in addition to an inner loop adaptation of the MCS a further adaptation of the first target value is performed. That is, there is a second, outer loop control mechanism for an ongoing transmission. This way, a better link adaptation may be obtained.
