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?
Option 1: To increase the transmission power of the Serving E-DCH cell.
Option 2: To reduce the average probability of missed NACKs (Negative Acknowledgments).
Option 3: To enhance the handover decision algorithm's accuracy.
Option 4: To verify that the average probability for missed ACKs (Acknowledgments) does not exceed specified values.
Explanation: Transmitting E-HICH using 12 consecutive slots in Cell 2 is aimed at verifying that the system can maintain a certain level of reliability, measured by the average probability for missed ACKs, during inter-cell soft handovers. This ensures data integrity and efficient retransmission handling in UMTS networks.
