Calculation Notes
- NRB table: based on common NR channel bandwidth / SCS combinations for FR1 and FR2.
- Formula: throughput = layers × modulation order × scaling factor × code rate × NRB × 12 × 14 × slots/s × (1 - overhead) × duplex share.
- TDD split: downlink and uplink share are derived from configured DL, UL, and flexible slot symbols.
- SDL/SUL: supplemental downlink disables UL throughput, supplemental uplink disables DL throughput.
- Code rate: default is the commonly used peak assumption of 948/1024 = 92.578%.
- Extended coverage: includes FR1 35 MHz and 45 MHz bandwidths, plus 1024QAM where the device and network support it.
