Question: In Dual Connectivity (DC) operation for E-UTRA/E-UTRAN, what is the maximum reception/transmission timing difference that a User Equipment (UE) can cope with in asynchronous DC operation between two Cell Groups (CGs)?
Option 1: Up to 10µs
Option 2: Up to 33µs for reception and 35.21µs for transmission
Option 3: Up to 500µs
Option 4: Up to 1ms
Explanation: Asynchronous DC operation allows for more flexibility in terms of timing between the two Cell Groups (CGs), accommodating larger timing differences. This is crucial for scenarios where synchronization between CGs might not be feasible or is less stringent, enabling the UE to handle up to 500µs of reception/transmission timing difference, which is beneficial for wider area coverage and more complex network topologies in telecom networks.
