Question: What is the purpose of the IE ModulationOrder in RRC protocol?
Option 1: To convey the minimum required bandwidth for a UE
Option 2: To indicate the maximum supported modulation order
Option 3: To specify the preferred coding scheme for data transmission
Option 4: To negotiate the maximum number of simultaneous bearers
Explanation: The IE ModulationOrder is used to convey the maximum supported modulation order, which is essential for the eNodeB to determine the suitable modulation and coding scheme for data transmission to the UE. This information element helps in optimizing the radio resource allocation and ensuring efficient data transfer over the air interface.
