Question: What is the primary cause of remote interference in TDD networks with the same UL/DL slot configuration?
Option 1: Multipath fading
Option 2: Atmospheric ducting phenomenon
Option 3: Co-channel interference
Option 4: Inter-symbol interference
Explanation: The atmospheric ducting phenomenon causes radio signals to bend back towards the Earth, allowing them to travel longer distances and potentially interfere with UL signals in victim cells. This is the primary cause of remote interference in TDD networks with the same UL/DL slot configuration.
