Question: What is the purpose of the FreqSeparationClassDL-Only information element in RRC protocol?
Option 1: To indicate the frequency separation between UL and DL frequencies.
Option 2: To specify the bandwidth of a single CC in a frequency band.
Option 3: To indicate the frequency separation between lower edge of lowest CC and upper edge of highest CC of DL only frequency spectrum in a frequency band.
Option 4: To determine the number of CCs that can be supported in a frequency band.
Explanation: The FreqSeparationClassDL-Only information element is used to indicate the frequency separation between lower edge of lowest CC and upper edge of highest CC of DL only frequency spectrum in a frequency band, which helps in managing radio resources efficiently.
