Question: In a TDD (Time Division Duplexing) system, during the measurement of transmitted signal power with a Gaussian filter, what is the primary purpose of stepping the centre frequency of the filter in contiguous 30 kHz steps across a specified range around the assigned channel frequency?
Option 1: To accurately determine the Occupied Bandwidth by identifying the limit frequencies containing 99.5% of the Total Transmitted Power.
Option 2: To measure the Adjacent Channel Leakage Ratio (ACLR) for interference assessment in neighboring channels.
Option 3: To perform a channel scan for available bandwidth for potential carrier aggregation.
Option 4: To optimize the transmission power for better coverage in rural areas.
Explanation: The process described involves measuring power across a range to accumulate and then determine the points at which 0.5% of the Total Power is reached on both the lower and upper bounds. This is directly related to calculating the Occupied Bandwidth, which is crucial for understanding how much spectrum a signal actually uses, ensuring compliance with regulatory requirements, and minimizing potential interference with other services.
