質問 41
What are the conditions for reselecting E-UTRAN or different system frequency cells with lower priority than the serving cell? (Multiple Choice)

A. Within the time interval TreselectionRAT, SServingCe11<Threshserving,low (service carrier low threshold) and low priority E-UTRAN have a cell SnonServingCe11,x>Threshx,low
B. The E-UTRAN frequency or the different system frequency of the cell with higher priority than the service frequency does not satisfy the reselection criterion.

質問 42
Regarding the LTE system message, which of the following descriptions is wrong?

A. SIB1 transmission is completed by PDCCH scheduling carrying SI-RNTI (SI-RNTI is the same for each cell)
