Formula 5G NR Power

Formula 5G NR Power

Reference Signal Power = Max Tx Power - 10 x log 10 (RBcell x 12) (dBm)

Contoh dengan Max Tx Power 40 dBm, maka jika :
Sub-carrier Spacing 15 KHz 270 RBs with 50MHz
Reference Signal Power = 40 – 10 x log10（270 x 12) = 40 – 35.10
Reference Signal Power = 4.9 dBm

Sub-carrier Spacing 30 KHz 273 RBs with 100MHz
Reference Signal Power = 40 – 10 x log10（273 x 12) = 40 – 35.15
Reference Signal Power = 4.85 dBm

Sub-carrier Spacing 60 KHz 130 RBs with 100MHz
Reference Signal Power = 40 – 10 x log10（130 x 12) = 40 – 31.93
Reference Signal Power = 8.07 dBm

Dan untuk
Total Transmit Power = Max Tx Power + 10 x log 10 (No. of Tx Antenna) (dBm)
Contoh :
Total Transmit Power with 8 Tx Antenna = 40 + 10 x log10 (8) = 40 + 9.03 =49.03 dBm
Total Transmit Power with 16 Tx Antenna = 40 + 10 x log10 (16) = 40 + 12.04 =52.04 dBm
Total Transmit Power with 64 Tx Antenna = 40 + 10 x log10 (64) = 40 + 18.06 =58.06 dBm
Total Transmit Power with 128 Tx Antenna = 40 + 10 x log10 (128) = 40 + 21.07 =61.07 dBm
