Why does gNB need IE NeedforGapsInfoNR from the UE?


The IE NeedForGapsInfoNR indicates whether measurement gap is required for the UE to perform SSB based measurements on an NR target band while NR-DC or NE-DC is not configured. (TS 138 331 - V16.4.1)

My question is: Why does the gNB need this information from the UE? Is it important for the cell re-selection procedure?
