Question: In ETC8 (E-UTRA and NB-IoT in-band multi-carrier operation) testing, how are multiple 5 MHz E-UTRA carriers placed within the Base Station RF Bandwidth for transmitter tests?
Option 1: Adjacent to each other starting from the lower Base Station RF Bandwidth edge, with a power boosted NB-IoT PRB at the outermost in-band position.
Option 2: Randomly distributed across the Base Station RF Bandwidth to maximize bandwidth utilization.
Option 3: Adjacent to each other starting from the upper Base Station RF Bandwidth edge, following the placement of a power boosted NB-IoT PRB.
Option 4: In alternating patterns with NB-IoT carriers throughout the Base Station RF Bandwidth.
Explanation: According to ETC8 generation rules for transmitter tests, after placing a power boosted NB-IoT PRB at the outermost in-band position, multiple 5 MHz E-UTRA carriers are placed adjacent to each other, starting from the upper Base Station RF Bandwidth edge, ensuring efficient bandwidth use while testing multi-carrier operation capabilities.
