Prerequisites for reaching the Peak 5G downlink Throughput (4T8R) :

In order to each the max peak 5G downlink single-user throughput for a 4T8R Ue, the below factors need to be gathered :

  • Two codewords (2T4R uses a single codeword)
  • 8 layers for RANK 4 (2T4R uses four layers)
  • 27-order MCS (256QAM is enabled) in all cases
  • No block errors
  • 1600 times of DL grants (4:1 for commercial use)
  • A maximum of 273 downlink scheduled RBs with a bandwidth of 100 MHz

In this case, for a 100 Mhz bandwith we will be able to reach a maximum of 1.8 Gbps Downlink Throughput.
