n the serving cell by an RRC configurable amount before reselection can occur, and Qoffset s,n and Qoffset frequency provide the possibility to bias the rese- lection toward particular cells and/or frequencies. The cell reselection parameters are illustrated in Figure 7.20. Normally, ranking is based on a comparison of the measurement quantities derived as described in Section 7.7.4.4, but in a multi-beam environment, it is possible to enable performance of cell reselection for the cell with the highest number of beams above Ssearch intra Cell 1 Treselect Cell 2 Qhyst Intra-neighbor Reselection from measurements start cell1 to cell2 Time (s) Figure 7.20 Idle mode intra-frequency cell reselection algorithm. 7 5G Radio Protocols the threshold (i.e. absThreshSS-BlocksConsolidation) among the cells whose R value is within rangeToBestCell of the R value of the highest-ranked cell. If there are multiple such cells, the UE will perform cell reselection for the highest-ranked cell among them. In this way, the UE prefers reselection for a cell with more high-quality beams, and degradation of a beam does not trigger immediate reselection. 7.7.4.3 Inter-Frequency/RAT Reselections Similarly to E-UTRAN in NR, priority-based reselection evaluation was chosen to be the main reselection method between different frequencies and RATs (called a layer from now on), as it was seen that operators would like to control how the UE prioritizes camping on different RATs or frequencies. In priority-based reselection, each layer is given a priority each layer is given a priority, and based on this information, the UE tries to camp on the highest-priority frequency/RAT if it can provide acceptable service. So that the UE can decide if acceptable service can be provided, the network allocates to each frequency/RAT a threshold (Thresh X, high) which has to be fulfilled before reselec- tion to such a layer is performed. A similar reselection as in intra-frequency reselections is utilized; that is, the new layer needs to fulfill the threshold fo
