But on average, approximately 25% are used for overhead channels PBCH, PDCCH, etc, so 75% of that number is in line what what you observed. As LTE uses different channel bandwidths both for FDD and TDD. I have never seen such values for the throughput in LTE FDD. The data rate always depends on the channel bandwidth. This tutorial explains how LTE downlink maximum throughput is determined.

On a bandwidth of 20MHz it’s either 75Mbps in SISO or 150Mbps for MIMO 2×2. The maximum code rate is 1.
No.
In similar way we can calculate the throughput of other channel bandwidth and the calculated number is provided below.
Throughput Thumb Rule. In order to calculate the data rate one must take into consideration not only the symbol but the code rate. 0. I don’t understand why the values you posted here are so different.The calculation assumes all resource elements are available for PDSCH. Please explain step by step.What would be the impact of carrier aggregation on throughput ?if work with LTE band 3 BW =10MHZ , MIMO , max expected throughput per cell and per user …Subcarrier in your example is considered as antenna?Tmobile is starting a wifi plan via fiber feeded LTE antennas. Bigger letters (4 pages) still only require 1 envelope so that would move the ratio of Throughput to Overhead higher (i.e. Andriy Ivaneyko Andriy Ivaneyko. There are some other parameter which affect the system capacity of an LTE eNodeB and given belowIn this post , we will find out the peak eNodeB capacity (Mbps) for different channel bandwidth supported in LTE system.
The no. For uplink there are certain constraints about modulation, this 75 Mbps throughput number is to be considered with 64 Modulation support at uplink.
Most of eNodeB does support 64 QAM in uplink but few UE only support 16 QAM as maximum modulation in uplink.In similar way we can calculate the throughput of other channel bandwidth and the calculated number is provided below. The difference of bandwidth and throughput and the formula to calculate download speeds against your purchased ISP bandwidth has also been shown here. You can also look at TS 36.213. This value are after considering overhead considering FDD duplexing mode with different transmission modes and referred from 3GPP document 36.213, Table 7.1.7.1-1, Table 7.1.7.2.1-1 and Table 7.1.7.2.2-1 . The 300 Mbps number is for downlink and not valid for uplink.In uplink we have only one transmit chain at UE end so no MIMO benefits.
LTE System support for flexible bandwidth like 1.4 MHz, 3 MHz ,5 MHz,10 MHz , 15 and 20 MHz and this bandwidth is the major contributor system capacity. So with 20 MHz we can get Maximum of 100.8 Mbps as calculation shown above with single antenna.
Let’s consider LTE system with 20 MHz FDD mode , there are 100 Resource Blocks and each Resource block have 12x7x2=168 Symbols per ms in case of Normal CP. Bandwidth is a term used to describe the maximum amount of data that can be transferred throughout your network. Throughput is controlled by available bandwidth, as well as the available signal-to-noise ratio and hardware limitations.
