Question: What is the primary impact on a UE's (User Equipment) uplink transmission if its carrier frequency error exceeds the specified limit of ±0.1 ppm?
Option 1: Increased power consumption due to repeated transmissions
Option 2: Reduced downlink data throughput
Option 3: Enhanced receiver sensitivity for better signal capture
Option 4: Increased transmission errors in its own uplink channel
Explanation: Exceeding the carrier frequency error limit of ±0.1 ppm primarily affects the UE's ability to accurately transmit on its allocated uplink channel, leading to increased transmission errors. This is because a significant carrier frequency offset can cause the transmitter to operate outside the expected frequency range, disrupting the orthogonality of signals in multi-user environments and increasing the bit error rate (BER) in its own uplink channel.
