A radio node and a UE are described, and methods and computer programs therein to handle separate aperiodic CSI reports for one or more static subframes, in which the direction of signal transmission is fixed, and one or more flexible subframes, in which the direction of signal transmission is variable. The method performed by a UE comprises receiving a trigger for an aperiodic CSI report as part of an uplink grant from a radio node in a static downlink subframe, said trigger indicating a CSI subframe set related to the one or more static subframes. The method further comprises reporting to the radio node, in a CSI reporting subframe, a result of an aperiodic CSI measurement for a CSI reference in the CSI subframe set. The method further comprises receiving a second trigger that relates to the one or more flexible subframes and reporting the results to the radio node.
