5G NR Throughput calculator


This Page provides information about 5G NR Throughput calculator. Сalculator allows to calculate the maximum throughput of 5G NR network for user (depending on his mobile device UE). Approximately data transfer rate of 5G NR can be calculated using the formula:

5G Throughtput formula

The calculation is based on the 3GPP TS 38.306 standard: NR User Equipment (UE) radio access capabilities and uses formula to obtain a 5G NR Throughput data rate in the DL (downlink) and the UL (uplink). To obtain the correct result, it is necessary to enter such important parameters as: mode of 5G network, number of aggregated carriers, number of MIMO layers, Bandwidth, Frequency range, modulation type, and so on.

  • Thanks for your wonderful program. -)

  • Good work. However can you please check this:

    When comparing same BW with SCS 15 or 30 KHz, you get really small throughput for the higher numerology (Numerology 1). This most probably is because with 30KHz you have to double it – with 15KHz there is 1 slot per subframe, while with 30KHz there are 2 slots per subframe.

    Regards
    Boyko S

    • Dear, Boyko S!
      You are right about “with 15KHz there is 1 slot per subframe, while with 30KHz there are 2 slots per subframe.”
      But for 15KHz we have 106 RB (20Mhz for example), for 30KHz we have 51 RB (20Mhz) – 3GPP 38.104

      This mean that we have more slots, but less RB.
      Throughput for 30kHz not double throughput for 15kHz

      Regards

  • How its differing for TDD can you explain?

    • In our tool you can can choose FDD or TDD mode:
      For FDD: all slots in subframe used in DL or UL

      Part of the Slots allocated for DL or UL = 1 (100%)

      For TDD: not all slots in subframe used in DL or UL

      For example:
      slots format 45:DDDDDD FF UUUUUU
      where D ,F, U – downlink or flexible or uplink symbol
      Part of the Slots allocated for DL: 6/14 = 0.42857 (43%)

      (38.213: Table 11.1.1-1: Slot formats)

  • Good day,
    I have two questions:
    1.The equation shows default the max LDPC code rate 948/1024. In case I want to use another MCS, shall I then use the code rate given in ETSI
    ETSI TS 138 214 V15.3.0 (Table 5.1.3.1-3)? e.g. MCS 18 = 822/1024.
    2. What is actually the meaning of Scaling Factor?

    Thanks in advance and thanks for this great tool!

    • Dear, Andy!
      1. I think yes, you can use this for another MCS.
      But in 3GPP TS 38.306 We do not have any information about it.
      Just Logic 😉
      Rmax = (Target code Rate (3GPP 38.214 Table 5.1.3)) / (1024)

      2. 3GPP TS 38.306 is not give information about ScalingFactor
      but if if you look at the LTE standards:
      Scaling factors used for Medium and High mobility.
      Should be configured per Carriers
      Scale Factor sets the value by which to scale the bandwidth and time lengths of the measured signal.

    Dear, Boyko S!
    You are right about “with 15KHz there is 1 slot per subframe, while with 30KHz there are 2 slots per subframe.”
    But for 15KHz we have 106 RB (20Mhz for example), for 30KHz we have 51 RB (20Mhz) – 3GPP 38.104

    This mean that we have more slots, but less RB.
    Throughput for 30kHz not double throughput for 15kHz

    Regards”

    Hello, yes you are right about RBs, but the throughput is megabits per second not megabits per RB. For BW 50 MHz you have SCS15KHz 270 RBs and SCS30KHz – 133. Round the half but in the same time 2 slots per subframe, so it is expected to have nearly equal thpt.
    Let’s take one example. 8 layer MIMO, TDD, 1 carrier, 50 MHz etc.
    With SCS 15KHz according the calculator you get 1982 mbps
    With SCS 30KHz you get 976 mbps.

    Br
    Boyko S

    • Dear, Boyko S!
      I think i found mistake in your calculation
      You should to change not only parameter: “BW:50MHz FR1 µ:30kHz” but and then parameter of carrier configuration “µ(j) -value of carrier configuration”
      After this you get:
      With SCS 15KHz (Q(j)m =8) according the calculator you get 1982 mbps
      With SCS 30KHz (Q(j)m =8) you get 1952 mbps. (not 976)
      In next update of calculator I will do auto-change for µ(j) parameter after change parameter: “BW:50MHz FR1 µ:30kHz”
      It is just “user interface problem” 😉
      Anyway thanks
      Regards

  • Good work.
    Thank you.

    Regards
    Boyko S

  • Wonderful. Only a small comment, for the tdd slot parts, it is not accurate for the uplink slot using 1 minus (the percetage of downlink slot) since there are some gap between dl symblo and ul symbol in the special subframe, such as the special subframe config is 6 dl symbol, 4 ul symbol, 4 gap symbol.

  • Great Help.Appreciate the effort

  • dear sir,
    There are any calculation tool to calculate the value of TBS(38.214-Table 5.1.3.1 and Table 5.1.3.2-1)?
    Thanks

    • Dear, Jiangyun
      We planning to do calculator of TBS value later.
      We don’t have it now.
      Thanks for your inquiry
      Regards

  • Dear, Is there a tool to estimate spectral efficiencies per 3GPP band and MIMO order?

  • Thanks for the Nice tool.
    I have a query, Is this tool takes care of “TDD-UL-DL-ConfigurationCommon” mentioned in 38213? Let’s take example of DDDSU having periodicity 2.5msec for mu=1.

  • hello,
    currently you are taking mcs = 28 for your calculation . if you can add MCS also as one of the parameter, it will be great help.

    • Dear, Atul!
      If you want to change MCS ( based on 3GPP 38.214 Table 5.1.3)
      You should to change Q(j)m modulation order and Rmax (Value depends on the type of coding from 3GPP 38.214,38.212)
      Where Rmax = (Target code Rate (3GPP 38.214 Table 5.1.3)) / (1024)
      I dont want to add MCS index becouse we have 3 table of MSC depend on “PDSCH-Config”
      Regards

  • Hi OlegV@5GTools:

    can you make a table the relation between MCS QAM TBS and Tput in one CC(BW 100MHz)?

    Thanks

  • Hello, Oleg! Could you explain how to calculate the throughput of the base station using your calculator?

    • Dear, Alex
      If you want to calculate throughput of the base station, You should to understand: how many cells do you have per Base station? (And cells configurations)
      For example:You have 1 base station with 3 transmitters and 6 Cells ( 2 Cell on 1 transmitter).
      3 Cell configuration BW:50MHz FR1 µ:15kHz: and 3 Cell configuration BW:100MHz FR2 µ:120kHz:
      You should use “5G NR THROUGHPUT CALCULATOR” to get Throughput per Cell then 1 base station Throughput= 3*cell1 Throughput +3*cell2 Throughput
      1 base station Throughput = 3*742(BW:50MHz FR1 µ:15kHz) +3*1386(BW:100MHz FR2 µ:120kHz) = 6384 Mbps
      Regards

      • Oleg! Thank you very much! You helped me a lot! I really appreciate it!

        • Hey, Oleg! Can you explain why do we use calculator of throughput for UE (3GPP TS 38.306) and get throughput per Cell ? thank you a lot!

          • Dear, Tom!
            Ue throughput depend on same parameters that cell throughput…But Ue can use not all PRB blocks…
            If you want to get Cell throughput you should to use all Cell PRB (Full Bandwidth), if you want to get Ue throughput use “other (enter number of PRB, FR and µ)”
            If Ue can use all PRB then Cell throuthput = Ue throuthput ( 1 user use all Сell resources)
            Regards, Oleg

  • What is the significance of overhead and scaling in throughput formula?

    • Dear Pulkit
      overhead – this part is not for user data ( just for control, broadcast etc…channel)…
      Scaling factor should be used for carrier aggregation ( % of carrier use)
      Regards

  • Hi

    Nice tool.
    One question though, how to calculate TP with ENDC case?
    By adding TP calcutated from 5GNR page and LTE page?

    • Dear, RealH
      I never seen in my practice how to 5G-4G Dual Connectivity (ENDC) work. But i think that radio configuration will be same like only 5G or like only 4G….in the first approximation i think tp Full =4G tp+ 5g tp… but maybe we should to use f(j) Scaling factor … or some more parameters…

  • I am not clear about the Frequency Band. 5G use the milimeter wave such as 28GHz, 36GHz. If I want to operate the calculator in 28GHz, what should I do?
    Thank you

    • Dear, Ezaz
      If You want to operate the calculator in 28GHz, You should to use this parameter “BW(j)- band Bandwidth, MHz (3GPP 38.104), should be selected with Frequency Range and µ(i) configuration” with FR2 (24250 MHz – 52600 MHz). For Example: “BW:50MHz FR2 µ:60kHz:”

  • How overhead and Scaling factor decided
    I got overhead was 0.14 for FR1 DL . But don’t know how it decided
    I got Scaling factor can be 1,0.8,0.75,0.4. But when it will be 1(0.8,0.75,0.4) are not very clear

  • Hi OlegV
    How do you considering about the UL-DL pattern: slot combinations in 5ms or 2.5ms
    I got the common config is:
    7DS2U for 5ms period
    DDDSU for 2.5ms period
    can it reach 100%(all are DL slot, DDDDD forexample)while calculation peak Tput?

    Thanks

    • Dear, Chao

      If you use UL-DL pattern (It is your equipment vendor configuration, it is different from 3gpp),
      you should to understand what is your µ configuration … then for example: µ = 30kHz

      DDDSU for 2.5 ms this mean that you have 4 “DDDSU” combination in 1 Radioframe (10 ms)
      1 Radioframe = 10 subframe, 1 subframe have 2 slot (µ = 30kHz), 1 slot have 14 symbols….
      This mean 1 Radioframe = 10*2*14 =280 symbols…… DDDSU =280/4 = 70 symbols,
      if DDDSU =100% then D=60%, S (special subframe, gap for example, or you should check your S conf) =20%, U=20% then
      you have DDDDDDDDDDDDDD DDDDDDDDDDDDDD DDDDDDDDDDDDDD SSSSSSSSSSSSSS UUUUUUUUUUUUUU
      Then you can check frame configuration from 3GPP D should by 60% from 14….. but 14*0,6 =8,4… ( U: 14*0.2=2.8)
      DDDDDDDDFFFFUU…. but you cant find this pattern….
      Your vendor is different from 3GPP standart 🙂 (All vendors is different from 3gpp at this moment)
      You should to use “Manual (vendor data)” parametr in calculator ( for example S= gap without D and U)
      and use 0.6 (60%) for DL and 20% for UL….
      Regards
      Oleg

  • Nice Tool, Could you please explain ,[ Tμs(j) = (10^-3)/(14*2^μ) – average OFDM symbol duration in a subframe ]

    How the value of Average OFDM symbol is calculating , i did not understand the first part (10^-3) why its used .

    • Maybe I can answer this:
      Let’s take μ =1(30kHz) as example. In this condition, 1ms corresponding to: 1 subframe = 14*2^1(2^1 is the slot number per subframe ref to TS38.211) = 28 symbol
      So 1ms corresponding to: 28symbols
      Convert the unit from ms to s(second)
      It means 10^-3s Corresponding to: 28 symbols
      Then: what is duration of one symbol?
      (10^-3)/28 it’s about 35.7*10^-6s or 35.7μs
      This is how Tμs(j) = (10^-3)/(14*2^μ) comes

  • Dear Oleg,

    Great and quick tool and is such a time saver. Thank you and awesome job! Do you have a similar calculator for the gNodeB side on DL from the massive MIMO radios??

    Earl@EJLWireless

    • Dear, Earl@EJLWireless!
      To get DL throughput massive MIMO of gNodeB you should:
      1. DL throughput massive MIMO = DL UE1 +DL UE2 + Dl UE3… ( at our calculator you should to use this way)
      massive MIMO mean that different UE can use same RB ( different location, not only Mimo layer).
      2. massive MIMO UE throughtput depend on sinr, RB number etc… When you use mMimo, you get better Antenna Gain
      ( 21~24 for 3.5 GHz)-> better SiNR, Modulation.
      For example: You have 20Mhz, , µ:15kHz, 106 Rb, Ue1 use 60 RB, UE 2 Use 60 RB ( 14 RB is same)
      5G NR Throughput mMimo =5G NR Throughput ue1 +5G NR Throughput ue2 > 5G NR Throughput without mMimo

      Regards, Oleg

  • I am not able to see the calculator here on the page?
    can someone give me the link please

  • Can we pay through MoneyGram? About $50 of payment.

  • How the FR1 values are calculated. Can you please elaborate and explain in details.

    • Dear,Suryakant!
      What do you mean “FR1 values are calculated”
      FR—-> Frequency Range 3GPP 38.104:FR1 (450 MHz – 6000 MHz).
      At our calculator when you click on “BW:5MHz FR1 µ:15kHz:” at “BW(j)- band Bandwidth” parameter, you select Frequency Range FR1…
      Regards, Oleg V.

  • This is applicable for indoor capacity dimensioning also?

    • Dear. Vivek!
      Why not?
      I think Yes, if your indoor 5G base station and UE equipment support modulation, mimo etc.

  • In Modulation Scheme, 1024 QAM is not listed but 1024 QAM is supported by 3GPP Rel-15.

    • Dear, Va!
      I cant find specification with 1024 QAM Support ( cant find it at 38.804 or 38.214). Can you tell the number?
      Anyway You can use Q(j)m modulation order =10 at Our Calculator (result will be correct)
      Regards, Oleg

  • Newbie question: why there is no input parameters for the number of beams I can achieve during transmission? With spatial multiplexing multiple users can use the same frequency and time resource but being differentiated in space allocation. Where am I wrong?

  • Dear Oleg,
    congrats to this nice tool.
    Can you please explain exactly the meaning of the scaling factor and in which case this value has to be different to 1.

    Thanks in advance
    Andy

    • Dear, Andy!
      38.306: Indicates the scaling factor to be applied to the band in the max data rate calculation. Value f0p4 indicates the scaling factor 0.4, f0p75 indicates 0.75, and so on. If absent, the scaling factor 1 is applied to the band in the max data rate calculation.
      This is part of “FeatureSetDownlink” indicates a set of features that the UE supports on the carriers corresponding to one band entry in a band combination.
      For more information you can read: 3GPP TS 38.331
      Regards, Oleg

  • Thanks for your useful tools ,
    by the way , do you know where i can find “Scaling factor” in OTA message ? i’m looking into lots of log , never found it , or it’s default by 1 ?

  • Hi Oleg,

    May I ask when we want to compute for the so called 5G cell capacity of say DL/UL 16/8 Layers, can we just simply enter v(j) to be DL 16 and UL 8? Many thanks for your kind advise. 🙂

    • Dear, Lion Rim!

      I think Yes. If you use Massive MIMO, you can get better Capacity for cell ( than 8 DL Mimo) because MU-MiMo ( different directions of beams).
      You can use v(j)Layers for DL 16 and UL 8.
      Regard Oleg
