Question: In E-UTRA Base Station (BS) radio transmission and reception, what is the primary purpose of defining a "dominant interferer proportion" in the context of inter-cell interfering UE transmissions for enhanced performance requirements?
Option 1: To optimize UE transmit power in synchronous scenarios.
Option 2: To accurately model the impact of strongest neighboring cell interference on overall network performance.
Option 3: To simplify the handover process between asynchronous cells.
Option 4: To reduce signaling overhead for interference mitigation techniques.
Explanation: Defining a "dominant interferer proportion" is crucial for understanding and modeling how the strongest sources of inter-cell interference (i.e., dominant interferers) affect the overall network performance, especially in scenarios with enhanced performance requirements. This helps in designing more effective interference mitigation strategies, thereby improving the quality of service across the network.
