In the context of measurement configuration in the presence of multiple carriers, and in particular supplementary cells, LAA SCells, a method is provided to scale the measurement period that takes into account the capability of the UE to perform, for example by means of multiple searchers or increased buffer capacity, to measure multiple carriers simultaneously. The method comprises determining a scaled period (p) according to the following equation: p=pDMTC*min[n, ceiling(NCC/NCC_support)]; selecting respective selected occasions for each of NCC carriers out of occasions for measuring a respective reference signal, wherein the occasions occur with the predefined period (pDMTC), and the respective selected occasions occur with the scaled period (p); and inhibiting a measuring of a respective reference signal at occasions different from the respective selected occasions for each of the NCC carriers.
