How does UE camp (synchronize) to a NodeB?

1. UE uses the primary synchronization channel (P-SCH) for slot alignment (TS
synchronization).
2. After aligning to NodeB time slot, UE then uses secondary synchronization channel (SSCH) to obtain frame synchronization and scrambling code group identification.
3. UE then uses scrambling code ID to obtain CPICH, thus camping to a NodeB.
