Question: What is the primary goal of coordinating interference in LTE radio technology on the basis of uplink and downlink?
Option 1: To reduce transmitted power and increase Physical Resource Blocks (PRBs)
Option 2: To improve Signal-to-Interference Ratio (SIR) and corresponding throughput
Option 3: To minimize spurious emissions of neighbor cells in low load scenarios
Option 4: To optimize ICIC related RRM functionality for short distance interferers
Explanation: Coordinating interference in LTE radio technology on the basis of uplink and downlink aims to improve Signal-to-Interference Ratio (SIR) and corresponding throughput. This is achieved through mechanisms employing channel quality indicators, which support scheduling/radio resource allocation functions.
