In case the UE has stored system information from the current cell with the same systemlnfoValueTag as the one that is currently indicated by systemlnfoValueTag in SystemlnformationBlockTypel , the UE then does not have to reacquire the system information until 3 hours has passed since it was received.

If the UE thus is configured with EN- DC, the AS layer will forward upperLayerlndication, as if the UE received the field from SIB2, to the upper layers, so that it is indicated to the end user that the UE is in coverage of NR (5G). If the UE is not configured with EN-DC, i.e. it has an LTE connection without NR SCG, the UE AS layer will instead indicate absence of the upperLayerlndication field to the upper layers, thereby indicating to the end user that the UE is not in coverage of NR (5G).
