Question: For a 1.28 Mcps TDD User Equipment (UE), what is the frequency range on both sides of the centre carrier frequency to which the spectrum emission mask applies?
Option 1: Between 0.4 MHz and 2.0 MHz
Option 2: Between 0.8 MHz and 4.0 MHz
Option 3: Between 1.0 MHz and 5.0 MHz
Option 4: Between 1.28 MHz (Mcps) and the edge of the channel
Explanation: The correct frequency range, as per the specified requirements for 1.28 Mcps TDD UEs, is between 0.8 MHz and 4.0 MHz on both sides of the centre carrier frequency. This range ensures out-of-channel emissions are properly managed relative to the UE's carrier power, maintaining spectral efficiency and minimizing interference in wireless communications.
