LTE Throughput Formula

Peak Data Rate Calculation

Throughput = RBs * 12 subcarriers * 14 symbols * Qm * R * layers * 1000 / 1ms
Where Qm = modulation order, R = code rate (~0.93)

LTE uses OFDMA with 180 kHz resource blocks (12 subcarriers x 15 kHz). Each subframe is 1ms with 14 OFDM symbols (normal CP).

Key Factors

  • Bandwidth: More RBs = higher throughput
  • MIMO: Spatial multiplexing doubles/quadruples capacity
  • Modulation: 256-QAM vs 64-QAM = 33% more bits
  • Carrier Aggregation: Combine multiple carriers
  • Overhead: ~25% for reference signals, control
