Question: In a UTRA FDD scenario, where a UE is connected to Cell 1 as the timing reference and Cell 2 is added to the active set, what is the defined range for setting the downlink DPCH time difference between Cell 1 and Cell 2?
Option 1: -50 to +50 chips
Option 2: -148 to +148 chips
Option 3: -200 to +200 chips
Option 4: -100 to +100 chips
Explanation: This range reflects the specified adjustment for downlink DPCH time difference between two cells in the active set, crucial for ensuring proper synchronization and minimizing interference between cells in UTRA networks.
