Question: What is a prerequisite for a User Equipment (UE) to support Resynchronization Signals in an Evolved Universal Terrestrial Radio Access Network (E-UTRAN)?
Option 1: The UE must support all optional features defined in the E-UTRA specifications.
Option 2: The UE needs to operate exclusively in Frequency Division Duplex (FDD) mode.
Option 3: The UE must support ce-ModeA-r13.
Option 4: The UE has to be capable of transmitting on all available uplink channels simultaneously.
Explanation: Supporting ce-ModeA-r13 is a requirement for a UE to utilize Resynchronization Signals, due to its dependency on specific operational modes within the E-UTRAN, impacting network efficiency and user experience.
