Question: What is the primary purpose of a Base Station (BS) reducing its transmit power outside the active part of a Tx time slot (burst without guard period) in a TDD system?
Option 1: To increase cell coverage area for better user experience.
Option 2: To minimize interference for other users receiving on the same frequency.
Option 3: To enhance the BS's power efficiency during idle periods.
Option 4: To prioritize traffic for high-priority users in congested networks.
Explanation: In TDD systems, minimizing interference is crucial since both uplink and downlink transmissions share the same frequency band but are separated in time. By reducing transmit power during inactive parts of the Tx time slot, the Base Station significantly decreases the likelihood of interfering with uplink transmissions from User Equipment (UE) or with other cells' downlink transmissions on the same frequency, thus improving overall network performance and user experience.
