Systems and methods are disclosed herein for configuration of multi-Radio Access Technology (RAT) early measurements. In one embodiment, a method performed by a wireless communication device comprises receiving system information from a first cell of a first network node and receiving a dedicated release message from the first cell comprising idle mode measurement configurations for a first RAT and/or a second RAT. The method further comprises performing a reselection to a second cell served by a second network node and receiving system information from the second cell comprising idle mode measurement configurations for the first RAT and/or for the second RAT. The method further comprises determining idle mode measurement configurations to be applied while in the second cell based on the idle mode measurement configurations comprised in the dedicated release message from the first cell and the idle mode measurement configurations comprised in the system information from the second cell.
