temp and Squal = Qqualmeas - (Qqualmin + Qqualminoffset) - Qoffsettemp. The signaled values Qrxlevminoffset and Qqualminoffset are only applied when a cell is evaluated for cell selection as a result of a periodic search for a higher priority PLMN, while camped nor- mally in a visited PLMN (VPLMN). During the periodic search for higher priority PLMN, the UE may check the S criterion of a cell using stored parameter values that were obtained from a different cell within the higher priority PLMN [12]. The cell selection parameters are described in Table 2.4. The following rules are used by the UE to limit the required measurements. If the serving cell fulfills Srxlev > SIntraSearchP AND Squal > SIntraSearchQ, the UE may skip intra- frequency measurements; otherwise, the UE must perform intra-frequency measurements. The UE must apply the following rules for NR inter-frequency and inter-RAT frequency measurements, which are identified in the SI and for which the UE has priority. For an NR inter-frequency or inter-RAT frequency with a reselection priority higher than the reselection priority of the current NR frequency, the UE is required to perform measure- ments on higher priority NR inter-frequency or inter-RAT frequencies [6]. For an NR inter-frequency with an equal or lower reselection priority than the reselection priority of the current NR frequency and for inter-RAT frequency with lower reselection priority than the reselection priority of the current NR frequency, if the serving cell fulfills Srxlev > SnonIntraSearchP AND Squal > SnonIntraSearchQ criterion, the UE may skip measure- ments of NR inter-frequencies or inter-RAT frequency cells of equal or lower priority; otherwise, the UE is required to perform measurements on NR inter-frequencies or inter- RAT frequency cells of equal or lower priority [6,8].
