Definition

The IE CSI-ResourcePeriodicityAndOffset is used to configure a periodicity and a corresponding offset for periodic and semi-persistent CSI resources, and for periodic and semi-persistent reporting on PUCCH, and for UE initiated CSI reporting. Both the periodicity and the offset are given in number of slots. The periodicity value slots4 corresponds to 4 slots, value slots5 corresponds to 5 slots, and so on.
