Question: What is the primary purpose of the `MeasId` Information Element in E-UTRA Radio Resource Control (RRC) protocol?
Option 1: To uniquely identify a User Equipment (UE) within a cell.
Option 2: To specify the transmission power of a base station.
Option 3: To define the parameters for handover decisions.
Option 4: To link a measurement object with its corresponding reporting configuration.
Explanation: The correct answer is Option 4 because, in the context of E-UTRA RRC protocol, `MeasId` identifies a measurement configuration, associating a specific measurement object with how those measurements should be reported, crucial for efficient radio resource management.
