Question: In a UMTS network, during an inter-cell soft handover involving cells within the same Radio Link Set (RLS), what is the primary purpose of transmitting E-HICH using 3 consecutive slots for Cell 2 (a cell not containing the Serving E-DCH cell)?
Option 1: To increase the transmission power for better coverage
Option 2: To reduce the average probability of missed NACKs (Negative Acknowledgments)
Option 3: To verify that the average probabilities for both missed ACKs (Acknowledgments) and false ACKs do not exceed specified values
Option 4: To enhance the handover success rate between cells in different RLS
Explanation: The correct answer, Option 3, aligns with maintaining reliable communication links in UMTS networks during handovers. It verifies that probabilities of missed and false ACKs remain within specified limits when E-HICH is transmitted over 3 consecutive slots for Cell 2, crucial for signal stability during handovers.
