Question: In a 3GPP TDD (Time Division Duplex) system with a 3.84 Mcps (Megachips per second) option, what is the primary reason for requiring RX frequency separation?
Option 1: To facilitate simultaneous transmission and reception in FDD (Frequency Division Duplex) mode.
Option 2: Due to the employment of Time Division Duplex (TDD), where each TDMA frame's timeslots can switch between transmit and receive.
Option 3: For efficient handling of dedicated carrier operations in uplink direction only.
Option 4: To enhance signal strength in areas with high interference.
Explanation: In TDD systems, the same frequency band is used for both transmission and reception, but at different times. This time-based separation necessitates RX frequency separation to prevent transmitter interference with the receiver during brief switching periods between transmit and receive timeslots within each TDMA frame, crucial in the 3.84 Mcps TDD option for maintaining signal integrity.
