Systems, methods, apparatuses, and computer program products for determining UE measurement performance in communication systems, such as NR, are provided. One method may include grouping configured carriers according to synchronization signal block measurement timing configuration (SMTC) to form carrier groups, distributing measurement gaps on the configured carriers according to an intra-frequency and inter-frequency gap sharing rule, and distributing the measurement gaps available for inter-frequency measurements among inter-frequency carrier groups according to the carrier groups with non-overlapping synchronization signal block measurement timing configuration (SMTC) or the carrier groups with overlapping synchronization signal block measurement timing configuration (SMTC) to create a distribution of the measurement gaps.
