Question: In a 5G Network, what determines whether attributes like arfcnDL or bSChannelBwUL must be explicitly set for an NRSectorCarrier resource?
Option 1: The type of transmission point (e.g., macro cell, small cell) associated with the NRSectorCarrier.
Option 2: Whether the NRSectorCarrier is directly associated with only one cell and its usage (e.g., supplementary uplink, partial bandwidth use).
Option 3: The User Equipment's (UE) awareness of the network resources used for its connection.
Option 4: The physical location of the antennae for the transmission point.
Explanation: If an NRSectorCarrier is not directly associated with one cell only (e.g., used for supplementary uplink) or uses only part of the cell's channel bandwidth, attributes like arfcnDL, arfcnUL, bSChannelBwDL, or bSChannelBwUL must be explicitly set because their values cannot be unambiguously derived from the referring cell.
