1. A radio node to handle separate aperiodic channel state information, 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 radio node comprising:
at least one processor; and
memory coupled with the processing circuitry, wherein the memory includes instructions that when executed by the processing circuitry causes the radio node to perform operations comprising:
indicating to a User Equipment, UE, a CSI subframe set in which the UE should perform an aperiodic CSI measurement for a CSI reference resource, where the CSI subframe set relates to the one or more static subframes or to the one or more flexible subframes;
indicating to the UE a CSI subframe set related to the one or more static subframes by use of a first trigger and indicating to the UE a CSI subframe set related to the one or more flexible subframes by use of a second trigger, wherein the first trigger and the second trigger is indicated by at least one bit, wherein the at least one bit indicates the first trigger when the at least one bit is set to a first value and indicates the second trigger when the at least one bit is set to a second value; and
receiving, in a CSI reporting subframe, an aperiodic CSI report from the UE comprising a result of the aperiodic CSI measurement for the CSI reference resource.
