Question: What are the two essential components that comprise the CarrierFreqGERAN Information Element to provide an unambiguous carrier frequency description of a GERAN cell in E-UTRA Radio Resource Control (RRC)?
Option 1: ARFCN-ValueGERAN and BandIndicatorGERAN
Option 2: Cell Identity and Location Area Code
Option 3: UTRA Absolute Radio Frequency Channel Number (UARFCN) and GSM Band
Option 4: E-UTRA Band and GERAN Cell Global Identifier
Explanation: The correct answer is Option 1 because, according to the specifications for CarrierFreqGERAN in the context of E-UTRA RRC, this information element is specifically defined as a sequence consisting of two key parts: ARFCN-ValueGERAN (Absolute Radio Frequency Channel Number for GERAN) and BandIndicatorGERAN. These components work together to provide a clear and unique identification of a GERAN cell’s carrier frequency, ensuring effective communication and resource management between different radio access technologies.
