How do you calculate peak throughput LTE?

How do you calculate peak throughput LTE?

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.

What is the maximum throughput in LTE?

100.8 Mbps
Maximum Physical Throughput in LTE is (16800 RE) * (6bits) * (1000ms) = 100.8 Mbps.

How is LTE capacity calculated?

To conclude, the LTE capacity depends on the following: Channel bandwidth….Downlink data rate:

  1. Pilot overhead (4 Tx antennas) = 14.29%
  2. Common channel overhead (adequate to serve 1 UE/subframe) = 10%
  3. CP overhead = 6.66%
  4. Guard band overhead = 10%

What affects LTE throughput?

Channel quality. Radio conditions impact user bit rates. The better radio conditions the higher throughput is available and vice versa. eNB (eNodeB, base station) selects Modulation and Coding Scheme (MCS) based on current radio conditions. The higher MCS the more bits can be transmitted per time unit.

How to calculate the peak throughput of LTE?

LTE throughput calculator Example Let’s assume there is a single UE, 20 MHz bandwidth and ideal radio conditions (to get peak throughput), then Number of RBs = 100 MCS Index = 28and TBS Index = 26 Based on that TBS = 75376 bits. Throughput = 75376 * 1000 = 75.376 Mbps. Assuming MIMO 2×2 we will get 75.376*2 = 150.752 Mbps.

How is throughput calculated for LTE TDD and FDD system?

3GPP LTE technology support both TDD and FDD multiplexing. The paper describes all the factors which affect the throughput like Bandwidth, Modulation, UE category and mulplexing. It also describes how we get throughput 300Mbps in DL and 75Mbps in UL and what are assumptions taken to calculate the same.

Where does the downlink throughput for LTE come from?

For LTE. In Downlink throughput is received through Physical Downlink shared channel (PDSCH) . Factors for throughput in PDSCH ? The throughput achieved by the PDSCH depends upon:

What are the different configurations of LTE TDD frames?

There are seven possible configurations for LTE TDD frame as shown below. Here D- is downlink, S- for Special subframe and U- for Uplink. As shown 5 ms periodicity frame have two “S” subframe and 10 mili sec frames have only one “S” subframe. Special subframe has 9 different configurations.
