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 |
