5g throughput calculation sharetechnote lte 12-1: OFDM parameters and CPRI Specification 6. This is the real measurement showing the correlation between SINR and Throughput. If you wants to have just overview of LTE, this section would not help you much, but if you are interested in protocol stack development or test case development these may be good tips. This site is for everything on 4G/LTE. I created the tutorial code on this page with the help of Matlab 5G Toolbox tutorial here. I made several examples of resource allocation and its ideal throughput as follows. Source : RedCap - expanding the 5G device ecosystem for consumers and industries - Whitepaper - Ericsson BWP is a part of the total channel bandwidth configured for a cell that is used for a UE at a specific moment of operation. In LTE, RBG size can be 1,2,3,4 depending on channel bandwidth. What would this mean ? 5G FR(Frequency Range) / Operating Bandwidth in Detail In NR, there are roughly two large frequency range specified in 3GPP. % the variable pss_scale and sss_scale in this example is used only to allocate different color onto the specified % resource element. Since one of the biggest goal for 5G is to achieve super high throughput, so high spectral efficiency can be an important criteria. Example 1: SNR (SINR) vs Throughput in a LTE Live Network . I think the purpose and concept of BWP is very similar to NarrowBand in LTE M1. AI for 5G Advanced toward 6G - Oregon ComSoc (2023) // Strongly Recommended; MWC 2024: Wireless AI interoperability in the multi-vendor AI world - Qualcomm(Feb 2024) MWC 2024: How Qualcomm wireless AI unlocks 5G mmWave efficiency There are much diverse preample format in 5G/NR comparing to LTE.

Next Calculate Ninfo as follows : Next step is same as downlink TBS determination process as shown below. It is used by the mobile device to connect to the packet data network and access the internet and other services. When the first talk about 5G started and some of prototyping test result came out, the focus was mainly around throughput. In LTE, there are only 4 different types of Preamble types which can be comparable to Long Sequence Preamble type in 5G/NR named as type 0,1,2,3, but there are many more in 5G/NR which does not have any equivalent types in LTE. As per 38. 5G NR Throughput Calculator | 5G NR Throughput Formula ; 5G NR Throughput calculator; Reference. But in NR, for the same BWP width, the RBG size varies depending on configuration type. < Case 5 > 1T=1R, or 2T=2R, or 4T=4R Number of SRS ResourceSet = upto two number of SRS ports for each resource is equal to 1, 2, or 4. Assuming that the bandwidth of each carrier is same, the more carriers are used the higher throughput you can expect (NOTE : In reality, there are cases where the bandwidth of each carrier would not be same. Using this PCI, the location of RS is % calculated. Source : 5G NR-Light (RedCap): Revolutionizing IoT - Qualcomm. 5G Mobile mmWave Technology Evolution Scalable Numerology: The flexibility in 5G numerology allows for the system to adapt to different deployment scenarios, frequency bands, and use cases, ranging from low-bandwidth, wide-area coverage to high-bandwidth, low-latency applications. NOTE: Refer to 3GPP 36. LTE - Low Throughput Application As far as I remember, most part of evolution in cellular communication so far has been focused mainly on increasing the throughput. Max Throughput Estimation. 4. 2, the max throughput can be estimated as follows. . The way to calculate the ideal throughput using these factors are explained in "Throughput Calculation Example" in Quick Reference page. Definition of BWP. In LTE (actually all other techology except NR), all the SIBs are broadcast periodically regardless of whether UE want it or not. Some background of adopting this kind of design is briefly described in IV-A of this paper as follows The way to calculate the ideal throughput using these factors are explained in "Throughput Calculation Example" in Quick Reference page. I've revised the code just a little bit for my own purpose. Сalculator allows to calculate the maximum throughput of 5G NR network for user (depending on his mobile device UE) or cell. For example, if the phone is trying to access a high-bandwidth video streaming service, the network may assign it to a slice that has a higher capacity for handling 5G MIB / SIB in Detail. 211 - Table 7. Max Throughput Calculators. Overall concept would be similar to TTI Bundling in LTE (in LTE TTI bundling is for Uplink. In many cases in this area, you will notice that a seemingly simple concept will turn out to be very complicated in terms of implementation. 5G CSI Report in Detail. 5G numerology provides the foundation for the flexible and adaptive nature of 5G NR, enabling it to First Calculate N'_RE using following formula. 5G/NR System Architecture is almost same as LTE System Architecture. This is the specification for LTE Dual Connectivity (not NR splitbearer) but I think similar idea would apply to NR split bearer as well. gNB may not want to get all the possible UE capability information and can restrict the type and amount of UE capability information by putting a specific requirements in UE capability Enquiry. pss_scale = 0. LTE level throughput (e. g, you can monitor the CPU utilization using Windows Task Manager) SLIV(Start and Length Indicator Value) SLIV is the Start and Length Indicator for the time domain allocation for PDSCH. These are what I found in internet. 5 GHz LTE & 5G | Speed With Sneed (Dec First Calculate N'_RE using following formula. com Throughput estimation is not easy and not as simple as can be calculated by a simple equation. Therefore, it is highly likely that 5G will use OFDM with much wider sub carrier spacing (meaning Wide Subcarrier) comparing to current LTE. E-UTRA sampling rates for the background information for this table. A tool to calculate the theoretical maximum for 5G-NR, with FDD, TDD, SDL and SUL band support. In terms of peak data rate requirement, 5G Redcap with different release (release 17/18) and LTE equivalent are well summarized in diagram as shown below. Approximately data transfer rate of 5G NR can be calculated using the formula: See full list on sharetechnote. These conditions are the most common condition for maximum throughput test. Theoretically, they can be any technologies, but in practice we usually mean NR(5G) and LTE(4G). In this page, I will describe on high level view on CSI report Definition of BWP. As you may notice, there is slight differences between the two versions. What are the multiple radio access technologies that wants to share a spectrum. 5G NR Power Saving Enhancements in Release 17 - Mediatek (Witepaper) YouTube. At the final stage of LTE advanced, we may be able to use max 100 Mhz using 5 carriers. They are not the parameter you would see in real life. 5G numerology provides the foundation for the flexible and adaptive nature of 5G NR, enabling it to . e, 5G or WiFi) at a specific moment and switch to another access network depending on situation ==> Switching PDSCH Aggregation is a kind of PDSCH repetition mechanism for reliable transmission (of course at the sacrifice of throughput). not my tool, but I think all of these tools are based on the fornula in 3GPP as summerized above. 1. At high level, the concept of CSI Report (Channel State Information) in NR is similar to CSI Report in LTE, but the details especially on the resource application of various reference signal and scheduing of the report is extremely complex than LTE. 2 PDCP entities. In 3GPP NR Specification, not so much details are explained about SplitBearer mechanism. This plot is automatically generated by AZQ Reporting tool and I just did some cosmetic touch on the chart. Matlab Toolbox : 5G Library : PUCCH Format 1; Matlab Toolbox : 5G Library : Slot Structure : Downlink / All Channels; Matlab Toolbox : 5G Library : Slot Structure : Uplink; Matlab Toolbox : 5G Library : PRACH / FR2 (120 Khz) Matlab Toolbox : 5G Library : SRS (120 Khz) Matlab Toolbox : 5G Library : CSI-RS; Matlab Toolbox : 5G Library : CSI Codebook Dec 11, 2020 · Estimating the Maximum Throughput and 5G Capacity for modern Wireless Networks is complex and requires understanding of the 5G standards. But in LTE PDCCH region, the PDCCH always spread across the whole channel bandwidth, but NR CORESET region is localized to a specific region in frequency domain. NR UE capability Information in general is much more complicated than LTE UE capability Information because NR Radio stack is more flexible and complex than LTE radio stack. At least as of now (Oct 2021), the industry seems to keep the scheduling as simple as possible and not to enable tricky features (e. Usually a cell configures multiple BWPs out of the total channel bandwidth and select a specific one at each moment of operation. Similarily in in NR the RBG size can only be 2,4,8 or 16 depending on the bandwidth of the BWP. According to 38. If the subcarrier width gets wider, the symbol length gets shorter (this is based on inverse relationship between frequency domain and time domain). 331. The PHICH position is the 'orange' resource elements in the first symbol. The first main factor you can think of is 'how many carriers are used for the data traffic'. The transport block CRC attachment in 5G PDSCH channel processing is a step that allows the UE to detect errors in the received transport block, ensuring reliable data transmission over the wireless channel. g, configured scheduling, SFI and introduction of cancellation, interruption etc) which may lead to too much complication and unstability of the Source : 5G NR-Light (RedCap): Revolutionizing IoT - Qualcomm. 211 4. Power Saving Techniques for 5G and Beyond. Meaning of each parameters in this equation is as follows. This page is aimed at summarising what’s involved: Throughput estimation for 5G is complex, involving many factors and deep knowledge of the 5G standards. 4; Followings are two example of PHICH allocation for the same system bandwidth of 5 Mhz. This criteria is especially important in lower frequency than in higher frequency (mmWave Range), because we don't have much free spectrum in lower frequency. Next Calculate the total number of REs for PUSCH as follows. 5G FR(Frequency Range) / Operating Bandwidth in Detail In NR, there are roughly two large frequency range specified in 3GPP. 5 GHz & mmWave | Sneed finds N41 & N261 in the Cle! (Nov 2020) T-Mobile 600 MHz LTE & 5G, 2. For now, you may get a little bit more detailed idea from LTE specification described in 36. With this large subcarrier spacing, this waveform can be much more robust than LTE/LTE-A in terms of phase noise. The only difference between these two examples is Cell ID. 211-Table 6. However, the rough estimation for a maximum throughput can roughly be estimated by following equation. In 5G, the DNN (Data Network Name) is the counterpart of APN in LTE. Throughput Calculation Example - FDD. When you say 'Trasport Block Size', it means the size of the array 'a' at the first step of the following process. This site is for everything on 5G/NR. So, in stead of directly jumping into max throughput test, increase the throughput step-by-step and check CPU utilization (e. The UE maintain the connection to both 5G and WiFi and steer the data flow either through 5G or WiFi depending on situation ==> Steering The UE can maintain the connection only to one of the access network (i. Following plot is from the data captured by a drive test tool Azenqos Drive Test tool (AZQ Android). Scalable Numerology: The flexibility in 5G numerology allows for the system to adapt to different deployment scenarios, frequency bands, and use cases, ranging from low-bandwidth, wide-area coverage to high-bandwidth, low-latency applications. One of the big difference between LTE and NR scheduling is that NR schedules not only for slot but also the symbols within the scheduled slot, whereas in LTE the schedule is done only for subframe level (not for the symbol levels within the scheduled subframe). % SSS first and then calculate PCI (Physical Cell ID) from the PSS,SSS. 2-4: PDSCH DM-RS positions for double-symbol DM-RS > AT&T 5G+ 1GIG Millimeter Wave inside Walmart (Oct 2020) iPhone 12 on Telstra 5G - Web browsing & YouTube (end-user experience) (Nov 2020) ATT 5G MMWAVE speed test 2020 iPhone 12 5G San Antonio (Nov 2020) T-Mobile 2. What is the maximum bandwidth we use for LTE as of now ? (May 2013) It is 20 Mhz assuming Single Carrier. 306-4. There are roughly two approaches to estimate the max throughput. If you are already familiar with LTE protocol stack or general concept of radio protocol stack, you would not need to spend too much time in reading this page. The illustration shown below is based on the following statement on absoluteFrequencySSB from 38. 840 - Study on User Equipment (UE) power saving in NR. Case 2 : I_MCS is in 'reserved' range. 323 4. This is same concept as RBG size in LTE Resource Allocation Type 0. 5G/NR System Architecture. (This kind of focus hasn't been changed much until mid 2013) At least, one thing for sure will be that the data rate will be at least several G bps. 5 GHz LTE & 5G | Speed With Sneed (Dec the higher-layer parameter lte-CRS-ToMatchAround, lte-CRS-PatternList1, or lte-CRS-PatternList2 is configured; and; the higher-layer parameter dmrs-AdditionalPosition is equal to 'pos1' and l0 = 3; and; the UE has indicated it is capable of additionalDMRS-DL-Alt < 38. Max Throughput Estimation . Followings are the list of configurations that I tried on this page.

So, simply put, 'Spectrum Sharing' in DSS would mean Spectrum Sharing between LTE and NR. The difference between this example and previous example is system bandwidth. 4G/LTE - Throughput Throughput Calculation - From UE Cateogory For many people working in LTE, one of the most important question would be what is the maximum throughput for a network, device or network operator. Jul 12, 2023 · This Page provides information about 5G NR Throughput calculator. The 5G Evolution:3GPP Releases 16-17 (5G Americas) RP-200494 - UE Power Saving in NR (Work Item Description) TR 38. Just take a brief look at the various figures / diagrams shown in this page would be enough. If we adopt LTE advanced technically available as of now, it can be max 40 Mhz using Carrier Aggregation with 2 carriers. Due to this, the symbol length in this frame can be 4 times shorter than LTE/LTE-A symbol length. I found a couple of examples of the max throughput calculator as listed below. 4G/LTE - Access Control Throughput Calculation - TDD; Throughput Calculation - From UE Cateogory; Throughput : Common Usually throughput calculated at this step is taken as a reference throughput (ideal throughput) because the throughput specified in UE Category represents the throughput at this step. 2. g, 100 Mbps and over) is pretty tough task not only for IP stack, but also the IP application software and CPU utilization. I tried to make it as practical as possible based on 3GPP higher layer specification. And this trend would not change much in future generation (e. Let's get into further details for some of the important parameters. Source : RedCap - expanding the 5G device ecosystem for consumers and industries - Whitepaper - Ericsson In this note, I want to approach NR scheduling with more of practical perspectives with the minimum set of factors. 4G LTE: 4G LTE Throughput calculator, 4G LTE Link budget calculator, 4G LTE Cell ID (ECI) Calculator, 4G LTE EARFCN calculator, 4G LTE RS RE Power calculator, 4G LTE Users (CCE) calculator, Spectral Efficiency 4G LTE calculator, 4G LTE Timing Advance Distance Calculator, EPRE (Energy Per Resource Element) Calculator, 4G Neighbor planning NOTE : It is required to have Matlab 5G Toolbox option to run this script . 5G UE First Calculate N'_RE using following formula . It is equivalent to LTE PDCCH area (the first 1,2,3,4 OFDM symbols in a subframe). 2; sss_scale = 0. Following code is based on '3GPP 5G NR PDSCH Throughput Simulation' in Matlab 5G Library help document. Large Subcarrier Spacing: As you see in the table, the sub carrier spacing is 4 times larger than LTE/LTE-A subcarrier spacing. One is what we usually call (sub 6 Ghz) and the other is what we usually call millimeter wave. We can configure the frequency domain location of SSB in Reference PRB coordinate as shown below and the position can be informed to UE via signaling message. Then let's think of 'Dynamic' part in DSS. However, in NR there are two different types of SIBs. Overall functionality and structure of MIB / SIB of NR is almost same as LTE, but there is one major differeces between NR and LTE. If you know the MCS index and number of RBs, you can calculate the throughput for that specific MCS idex and RB as follows: Definition of BWP. g, 5G). In LTE, APN (Access Point Name) is used as an identifier for a specific network operator's packet data network. 5, A carrier bandwidth part is defined as follows : Carrier Bandwidth Part is a contiguous set of physical resource blocks,selected from a contiguous subset of the common resource blocks for a given numerology(u) on a given carrier. dusagzrbsllfxckflorequdkohdrmwgbcurkdzymmvatjmofy
