Question: What is the primary impact on the uplink if a User Equipment (UE) exceeds the specified ±0.1 ppm carrier frequency error on each carrier?
Option 1: Increased power consumption in the UE
Option 2: Reduced downlink data throughput
Option 3: Enhanced receiver sensitivity at the base station
Option 4: Increased transmission errors in the uplink own channel
Explanation: Exceeding the specified carrier frequency error of ±0.1 ppm can lead to a desynchronization between the UE's transmitted signal and the expected reception timing at the base station. This desynchronization increases the likelihood of bit errors, thereby increasing transmission errors in the uplink own channel, as the base station may struggle to correctly decode the received signals.
