Question: In a UMTS network, during an inter-cell soft handover involving cells defined by the Radio Link Set (RLS), what is the primary purpose of transmitting E-HICH using 12 consecutive slots in Cell 2 (a cell not containing the Serving E-DCH cell)?
Option 1: To increase the transmission power for voice calls
Option 2: To verify that missed ACK and false ACK probabilities do not exceed specified thresholds
Option 3: To facilitate faster handover to a cell with better coverage
Option 4: To enhance data throughput for streaming services
Explanation: Transmitting E-HICH using 12 consecutive slots in Cell 2 evaluates the reliability of the Hybrid Automatic Repeat Request (HARQ) process, measuring average probabilities of missed ACKs and false ACKs to ensure error rates remain within defined limits for efficient wireless resource management during inter-cell soft handovers.
