摘要：A method for assisting the adaptation of a signal from a first node (100) to asecond node (120) is provided. The first node communicates with the second node in awireless communication system (110) over a radio link (130). The second node is

configured to comprise a codebook, which codebook comprises a set of possibleinformation alternatives used for assisting the adaptation of a signal from the first nodeto the second node. The second node may select an information alternative from acodebook and send it to the first node to assist the first node how to adapt the signal.The first node is arranged to know a number of subsets, each subset comprising a part ofpossible information alternatives. The method comprises the steps of sending aconfiguration request to the second node to restrict the selection of informationalternatives to one of the subsets; receiving an information alternative from the secondnode, which is selected among the at least one subsets configured according to theconfiguration request.
