Question No : 2
The value of cell reselection offset PI affects the calculation of C2 during cell reselection. If cell A and cell B are adjacent to each other, the CRO of cell A=10, the CRO of cell B=10, and the mobile phone resides in cell A. The MS test shows that C1=40 in cell A and C1=35 in cell B. It is known that PI=1 in cell A, PI=0 in cell B, and PT are both 0. What are the C2 values in cell A and cell B?
A. C2=50 in cell A, C2=45 in cell B
B. C2=50 in cell A and C2=35 in cell B
C. C2=40 in cell A and C2=45 in cell B
D. C2=35 in cell A and C2=50 in cell B

Which statements about network color codes are correct? (Multiple choice)

• A.NCC and BCC together form a base station identification code (BSIC), which is transmitted on the synchronization channel (SCH) of each cell
