Question: How does an eNodeB (eNB) identify a User Equipment (UE) as a Category 0 Low Complexity UE in a cellular network?
Option 1: Based on the UE's transmitted power level and received signal strength.
Option 2: Through analysis of the UE's data transmission rate and latency tolerance.
Option 3: By receiving a specific 'Low Complexity' indicator from the Mobility Management Entity (MME).
Option 4: Using the Logical Channel ID (LCID) for Common Control Channel (CCCH) and the reported UE capability.
Explanation: The correct identification method is based on technical attributes directly related to the UE's capabilities and signaling. The LCID for CCCH, which defines how control information is signaled, combined with the UE's self-reported capability, provides the eNB with the necessary information to determine if a UE is of low complexity (Category 0). This method is precise and relies on standardized signaling protocols within the cellular network, ensuring accurate identification without relying on indirect indicators like power levels or data rates.
