# Average Cell Throughput Calculations for LTE

Average Cell Throughput requires the following simulation results

• Average SINR distribution table (system level result), which provides the SINR probability

• Average throughput or spectral efficiency versus average SINR table (link level result)

For urban channel model and a fixed inter-site distance of 1732m,downlink throughput for LTE for different values of SINR is shown below.

MCS vs SINR

Average Cell Throughput=Σ(Pi*Ri)

where

Pi=Probability of occurrence of a specific SINR value at cell edge obtained using simulations
Ri=Average throughput corresponding to SINR range

Let us consider the following distribution for the SINR at the cell edge:

P1=0.5 (SINR=1.50-3.50 dB)
P2=0.25 (SINR=3.50-7.00 dB)
P3=0.15 (SINR=7.00-9.50 dB)
P4=0.10 (SINR=9.50-11.50 dB)

Cell Throughput=(0.50*4)+(0.25*6)+(0.15*8)+(0.10*12)=5.9 Mbps

Note: This throughput is much less than the theoretical maximum which assumes that the full 20 MHz bandwidth is being utilized in a 4×4 MIMO configuration.

I am undergratuate student
may you help me getting understand calculation of lte capacity for each cluster and each cell

2. fezo says:

thanks this info are sooo useful

3. Sherif El-Gharabawy says:

What would the average user throughput in LTE be in case of having only 10 MHz bandwidth in 2600 band?

4. farzeen says:

I am an undergrad student and i am researching on 4G LTE networks, I am currently working on the research paper ‘Modeling and Analysis of K-Tier Downlink Heterogeneous Cellular Networks’ by Harpreet S. Dhillon, Radha Krishna Ganti, Francois Baccelli, Jeffrey G. Andrews. Can anyone give me the matlab coding or simulation results for the graphs of this paper?

5. yousef says:

Thank you very much for the useful info.
Do you know from whence can I get a similar table for the uplink data rates?

6. Kamil says:

Thank you for this post. Do you know if there is a reference MCS vs SINR in the standards for the uplink? I saw one in 36.214 Table 8.6.1-1: Modulation, TBS index and redundancy version table for PUSCH. It only includes MCS Indexes and Modulation order but doesn’t include the coding rates nor sinr thresholds. Thanks.

Sir
I am doing Phd in 4G Lte Advanced.

do you have tools for Security analysis and testing of 4G LTE Advanced(Integrity,Confedentiality and Authentication Verification tools)?

if you do have this then Inform me,I want to use those tools also for my PhD research.

Please send me document regarding FER coded,FER uncoded,Throughput Coded,Throughput Uncoded,Throughput Useful,Blocksize Coded,Blocksize uncoded,Used CQI for cell specific and User Specific data.Also tell me what units to use for them and units along x axis and Y axis.

Thanks&Regards

Which is better to depend on SINR or RSRQ?

9. Lina says:

I am making a dimensioning tool for lte and I need solid equations and calculations of cell throughput or cell capacity , thanks in advance.

10. Lina says:

I am an undergrad student preparing my graduation thesis, can you help me with more simulation results, different SINR probabilities for other clutter types and different conditions.

11. David says:

Thanks for this useful post! In your opinion, what is more important to measure, RSRQ or SINR? Which of those has more impact on the throughput or user quality? Thanks again!

12. Praveen says:

Thanks for posting the simulation results.
I have a question on this SINR/throughput table, is this table for specific scenario since LTE DL throughput can go upto 150Mbps if it is MIMO and 20MHz bandwidth.
