Table 3 Basic comparison of the algorithms

From: Reliability enhancement in multi-numerology-based 5G new radio using INI-aware scheduling

  Advantages Disadvantages
Random scheduling The best scheduling flexibility Cannot provide fairness especially for edge UEs
Algorithm 1 Maximizes SIR at the edge UEs; good scheduling flexibility. No enhancement for non-edge outer users’ SIR
Algorithm 2 Maximizes SIR at the edge UEs; additionally protects non-edge outer users more than algorithm 1; increases overall SIR A small loss in scheduling flexibility
Proportional fair Increases SIR at the edge UEs compared to random scheduling Cannot provide the best SIR for edge UEs while balancing fairness between all UEs
