# How is LTE throughput calculated?

## How is LTE throughput calculated?

If modulation used is 64 QAM (6 bits per symbol) then throughput will be 16.8×6=100.8Mbps for a single antenna port. If we consider a 2×2 MIMO system then this throughput will be double i.e. 100.8×2= 201.6 Mbps and with 4×4 MIMO system then throughput is about 100.8×4= 403.2 Mbps.

## How is LTE TBS calculated?

Step to Calculated TBS The total number of REs within the bandwidth of a single RB is 12 x 14 = 168 using normal cyclic prefix. The final value is multiplied by the number of allocated Resource Blocks to generate a value for .

## What is the throughput of LTE?

for LTE is 300 Mbps in Downlink and 75 Mbps For a LTE system with 4×4 MIMO (4T4R) the throughput will be in Uplink.  Throughput is four times of single chain throughput. i.e. 403.2 Mbps.

## How can I improve my DL throughput in LTE?

The easiest way is to give a higher priority to L1800 and that will shift most of the UEs in L1800 coverage away from L800. This will ensure better CQI for users and thus a better throughput. Another way would be to keep them on same priority and provide a frequency offset to move the users to L1800.

## What is LTE capacity?

The maximum data transmission rate of LTE cell is 100 Mb/s in downlink direction and 50Mb/s in uplink, and this rate can be enhanced with deploying different techniques like MIMO, carrier aggregation, and many others.

## How is LTE code rate calculated?

The calculation of LTE code rate is done based on MCS, PRBs and OFDM symbols per slot. The LTE code rate calculator outputs code rate. It takes into account percent of REs used in control channel operation. The PRBs stands for Physical Resource Blocks allocated to the UE by eNB.

## What is code block in 5G?

In fifth generation (5G) new radio (NR), the medium access control (MAC) layer organizes the data into the transport block and transmits it to the physical layer. The transport block consists of up to million bits. The code block consists of up to 8448 bits.

## How do you calculate subcarrier in LTE?

According to LTE specifications, for 10 MHz bandwidth channels, the number of resource blocks= 50, each resource block is assigned 12 sub carriers for the duration of 0.5 seconds of 6-7 ofdm symbols. The number of bits in one resource block= 12x7x no.

## What is the throughput equation?

All Answers (3) The throughput efficiency formula can be calculated more than one way, but the general formula is I = R * T. In other words, Inventory = Rate multiplied by Time, where “rate” is the throughput. But if you solve for R, you would get R = I / T, or Rate = Inventory divided by Time.

## How to calculate LTE throughput in a calculator?

This LTE throughput Calculator is used for calculation of throughput as per 4G LTE standard. This calculator on LTE throughput is based on MCS, Number of PRBs (Physical Resource Blocks) and number of MIMO antennas. LTE throughput calculator EXAMPLE: Input : MCS = 10, PRBs = 20, Number of MIMO Antennas = 2

## How to calculate LTE data rate for single chain?

Throughput = data rate = 16.8 x 6 = 100.8 Mbps for single chain. LTE 4×4 MIMO (4T4R) 100.8 x 4 = 403.2 Mbps for DL. But there is 25% overhead use for controlling and signaling so 403.2 x 0.75 = 302.4 Mbps ~ 300 Mbps. For UL we have only one transmit chain at UE end so after 25% 100.8 x 0.75 = 75.6 Mbps ~ 75 Mbps.

## How to calculate the LTE transport block size?

Another way for LTE throughput calculation is to use Table number 7.1.7.1-1 which gives Transport Block Size(TBS). TBS indicates No. of bits that can be transmitted in one subframe per Transmit Time Interval. From the table with RBs of 100 and TBS index of 26, Transport Block Size is 75376.

## How to calculate LTE throughput with no MIMO?

When no MIMO is enabled there will be single antenna, for 2×2 MIMO enter 2 and for 4×4 MIMO enter 4 as number of antennas. which mentions example of how to enter various input parameters and calculate 5G NR throughput as defined in 3GPP 38 series of documents (3GPP TS 38.306, 38.101-1, 38.101-2, 38.211).
