Question: What are the key factors influencing the implementation feasibility of controlling co-site inter-sector co-channel inter-subband interference in FR1 wide area Base Stations (BS)?
Option 1: Maximum BS transmit power, Number of co-site sectors, Spatial isolation techniques, Beam nulling capability, Frequency isolation, and Digital interference suppression.
Option 2: Site location, Antenna height, User Equipment (UE) density, Cell throughput, and Modulation schemes.
Option 3: Duplex mode selection, Carrier frequency, Bandwidth allocation, Handover protocols, and Cell ID assignment.
Option 4: Network topology, Fiber connectivity, Power supply redundancy, Cooling systems, and Maintenance access.
Explanation: The correct answer is Option 1 because it accurately lists the key implementation aspects that influence the feasibility of controlling co-site inter-sector co-channel inter-subband interference in FR1 wide area BS. These factors directly impact the technical capability to manage interference within specified limits, unlike the other options which are relevant to telecommunications but not specifically crucial for controlling this type of interference.
