This work models and predicts the DL-Throughput by utilizing LTE data measurements to train supervised ML models. It is because there is some subframes where you cannot allocate full RBs (100 RBs in case of 20Mhz, Cat 3). Ericsson defined throughput (UL or DL) is "the speed at which packets are being transferred by the time the first packet has been scheduled in the air interface". Simply select network type and type in the LCID/CID. A proprietary dataset is utilized to train and test the model. Feature selection is LTE is rapidly gaining momentum for building future 4G cellular systems, and real operational networks are under deployment worldwide.

There are various purpose (reasons) for each different Transmission Mode. This post is to address common issues that affects downlink throughput and also to dig into possible solutions. This is a simple and straightforward formula for data rate calculation. Use this calculator to calculate LTE throughput, and carrier aggregation Throughput. What is Ideal/Expected throughput ? One of the most common questions that I have been getting for the past 10 years or so (probably from early HSDPA period and all the way up to now) was 'I have a UE with such and such category, what kind of throughput I need to get from this device ?' (Usually they carry the document like 36. In order to determine physical layer performance, we need to calculate the total physical resources available for different bandwidths of downlink transmission. Actually the calculation is too simple, […] This throughput often get configured with the throughput calculated at the last step of this process. Finally, we suggest scaling the proposed model into the future standalone 5G network. There is not one factor, but a number. Also Refer LTE throughput basics>> and LTE code rate calculator>> to understand the concept to derive TBS from THROUGHPUT (SPEED in MBPS) CALCULATION IN 4G LTEIn this video we have shown 4 methods by which throughput can be calculated in LTE and how various factors af. 4G LTE Network Throughput Modelling and Prediction Abstract: The past decade has witnessed a staggering evolution in cellular networks. 4 Mbps Throughput Calculation - TDD . Almost whole of this site is about LTE. Throughput Optimization. 39 for the uplink. Even with PC to PC direct connect, it is not easy to achieve this level of throughput.

The key difference is 'number of subframes /sec' parts as marked in red. Asynchronous HARQ, on the other hand, is a technique in which the UE sends data to the base station, and the base station sends an ACK or NACK message to the UE in a later subframe. Let’s assume, the UE is in good radio condition and its capability is available for 150 Mbps for downlink and 50 Mbps for uplink. The results in scenario 1 show that the normalized throughput of the implemented LTE ESPE network is 0.
