Question: What is a possible action taken by an eNB (eNodeB) to enhance the detectability of reference signals from another eNB for Radio Interface based Synchronization (RIBS)?
Option 1: Adjusting its own transmission power to minimize interference
Option 2: Requesting the interfering eNB(s) to adjust their antenna orientation
Option 3: Requesting the interfering eNB(s) to enable subframe muting via network signaling
Option 4: Automatically switching to a different synchronization method
Explanation: In the context of Radio Interface based Synchronization (RIBS), improving the hearability of reference signals is crucial. Requesting the interfering eNB(s) to enable subframe muting via network signaling directly addresses this need, enhancing synchronization accuracy by temporarily ceasing or reducing transmissions in specific subframes to ease detection of desired reference signals without interference.
