Channel state information reporting frequency optimization

An apparatus comprising:

• at least one processor;
• at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus to perform:
• receiving from a user equipment, UE, supporting Carrier Aggregation, CA, Channel State Information, CSI, reports for a Primary Component Carrier, PCC, for one or more previous time slots and for a current time slot;
• receiving, from the UE, CSI reports for a Secondary Component Carrier, SCC, wherein the CSI reports include at least one CSI report for a previous time slot, wherein each CSI report from the UE includes a value of at least one channel state indicator reported by the UE;
• predicting a value of the channel state indicator for the SCC for the current time slot, wherein the value is predicted based upon one or more values of the channel state indicator reported by the UE for the PCC for the one or more previous time slots and for the current time slot and at least one value of the channel state indicator reported by the UE for the SCC for the previous time slot.
