Lte 5g throughput calculation sharetechnote. What would this mean ? Definition of BWP.
- Lte 5g throughput calculation sharetechnote In LTE, RBG size can be 1,2,3,4 depending on channel bandwidth. I tried to make it as practical as possible based on 3GPP higher layer specification. First Calculate N'_RE using following formula. Following code is based on '3GPP 5G NR PDSCH Throughput Simulation' in Matlab 5G Library help document. How throughput is impacted ? In case of SU-MIMO (Single User MIMO), we don't differentiate throughput of transmitter (gNB) and reciever (UE) because they are same. Due to this, the symbol length in this frame can be 4 times shorter than LTE/LTE-A symbol length. For now, you may get a little bit more detailed idea from LTE specification described in 36. Final goal is to converge the core part of existing non-3gpp technolo 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. Large Subcarrier Spacing: As you see in the table, the sub carrier spacing is 4 times larger than LTE/LTE-A subcarrier spacing. the total number of different DCI sizes with C-RNTI monitored per slot <= 3. g, you can monitor the CPU utilization using Windows Task Manager) 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. Downlink : QPSK, 16 QAM, 64 QAM, 256 QAM with the same constellation mapping as in LTE; Uplink : QPSK, 16 QAM, 64 QAM, 256 QAM with the same constellation mapping as in LTE . SDR. Tech I created the tutorial code on this page with the help of Matlab 5G Toolbox tutorial here. 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 Throughput Calculation Example - FDD . 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 PDCP entities. Fundamental logic of the GAP setting is same as in LTE and Legacy case as explained above. in this case most of UE fails at PDSCH decoding and report HARQ NACK causing PHY layer retransmission. At the final stage of LTE advanced, we may be able to use max 100 Mhz using 5 carriers. Meaning of each parameters in this equation is as follows. Largest component carrier bandwidth not smaller than 80 Mhz for at least one numerology is supported ([1]) Waveform is based on OFDM ([2]) But in case of Cat 4 or higher, it would be harder to achieve max throughput with CFI value 2 or 3. Example 1: SNR (SINR) vs Throughput in a LTE Live Network . 5G/NR System Architecture is almost same as LTE System Architecture. Followings are agreed at RAN1 #85. 211 - Table 7. Followings are two example of PHICH allocation for the same system bandwidth of 5 Mhz. 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. Just take a brief look at the various figures / diagrams shown in this page would be enough. SLIV(Start and Length Indicator Value) SLIV is the Start and Length Indicator for the time domain allocation for PDSCH. g, 5G). These conditions are the most common condition for maximum throughput test. Some background of adopting this kind of design is briefly described in IV-A of this paper as follows 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 First Calculate N'_RE using following formula. QoS Structure; QoS Mapping in Signaling Message; Mapping between IP packet and QoS Pipe Max Throughput Calculators. Some background of adopting this kind of design is briefly described in IV-A of this paper as follows 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. If we adopt LTE advanced technically available as of now, it can be max 40 Mhz using Carrier Aggregation with 2 carriers. e, at 5G/NR System Architecture. Recap the procedure, it can be summarized as follows. Case 2 : I_MCS is in 'reserved' range. 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. 5G(NR) Band/Freq. 2. Converged Connectivity - ATSSS/5WWC . 211 7. 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. There are roughly two approaches to estimate the max throughput. Qos in 5G (Quality of service in 5G) - Part 1 (YouTube) Qos in 5G (Quality of service in 5G) - Part 2 (YouTube) QoS (Quality of Service) in 5G (YouTube) SERVICE DATA ADAPTATION PROTOCOL (SDAP) (YouTube) 3GPP 38. Next Calculate Ninfo as follows : Next step is same as downlink TBS determination process as shown below. I made several examples of resource allocation and its ideal throughput as follows. Overall concept would be similar to TTI Bundling in LTE (in LTE TTI bundling is for Uplink. However, the rough estimation for a maximum throughput can roughly be estimated by following equation. Some background of adopting this kind of design is briefly described in IV-A of this paper as follows First Calculate N'_RE using following formula. 5G NR Throughput Calculator | 5G NR Throughput Formula ; 5G NR Throughput calculator; Reference. 1. One can refer following pdf which covers snapshot of 3GPP TS 38. Theoretically, they can be any technologies, but in practice we usually mean NR(5G) and LTE(4G). It is equivalent to LTE PDCCH area (the first 1,2,3,4 OFDM symbols in a subframe). In case of 2 x 2 MIMO in LTE, each sub frame has different locations for reference signal for each antenna. not my tool, but I think all of these tools are based on the fornula in 3GPP as summerized above. . 501 - 5G;System architecture for the 5G System (5GS) => Section 5. 323 4. Source : RedCap - expanding the 5G device ecosystem for consumers and industries - Whitepaper - Ericsson This site is for everything on 4G/LTE. 2 and following is my interpretation. But in NR, for the same BWP width, the RBG size varies depending on configuration type. Similarily in in NR the RBG size can only be 2,4,8 or 16 depending on the bandwidth of the BWP. In this page, I will describe on high level view on CSI report 5G FR(Frequency Range) / Operating Bandwidth in Detail In NR, there are roughly two large frequency range specified in 3GPP. As LTE evolves, we got increasing number of measurement gap definition and with the introduction of NR, this list got exploded as below. Converged Network is a collective name for various technologies to utilize 5G core network for the data path (and some control plane in some cases) of non 3gpp communication as illustrated below. If the subcarrier width gets wider, the symbol length gets shorter (this is based on inverse relationship between frequency domain and time domain). it indicates the size of the Active Bandwidth Part Therefore, it is highly likely that 5G will use OFDM with much wider sub carrier spacing (meaning Wide Subcarrier) comparing to current LTE. But for MU-MIMO, we need to consider the throughput for transmitter and reciever differently. In this note, I want to approach NR scheduling with more of practical perspectives with the minimum set of factors. 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. You may think NR(5G) waveform is much simpler than the LTE waveform. 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 Dec 11, 2020 ยท Above mentioned formula has been used along with 5G NR Physical layer parameters and other 5G NR system parameters in order to develop 5G NR throughput calculator. This is the real measurement showing the correlation between SINR and Throughput. This site is for everything on 4G/LTE. This is the specification for LTE Dual Connectivity (not NR splitbearer) but I think similar idea would apply to NR split bearer as well. In LTE, the waveform generation equation (basically IFFT equation) is split into two parts just to remove the point located at DC location (i. 2-4: PDSCH DM-RS positions for double-symbol DM-RS > 5G CSI Report in Detail. About. chatTechnote. 5 GHz LTE & 5G | Speed With Sneed (Dec Since one of the biggest goal for 5G is to achieve super high throughput, so high spectral efficiency can be an important criteria. In case of LTE as an example, we use the method described as shown below. Measurement GAP for LTE and NR . Overall functionality and structure of MIB / SIB of NR is almost same as LTE, but there is one major differeces between NR and LTE. In short, the max throughput for the reciever (UE) does not change. Max Throughput Estimation. However, in NR there are two different types of SIBs. 300 - NR and NG-RAN Overall description; Stage-2 => Chapter 12; 3GPP 23. 211 4. PDSCH Aggregation is a kind of PDSCH repetition mechanism for reliable transmission (of course at the sacrifice of throughput). 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. If you know the MCS index and number of RBs, you can calculate the throughput for that specific MCS idex and RB as follows: PHY layer throughput in bits = Transport Block Size (bits) / subframe x Number of the scheduled subframes / sec = ???? bits/sec Throughput estimation is not easy and not as simple as can be calculated by a simple equation. Followings are the list of configurations that I tried on this page. In LTE (actually all other techology except NR), all the SIBs are broadcast periodically regardless of whether UE want it or not. 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. Throughput TechSlide . g, 100 Mbps and over) is pretty tough task not only for IP stack, but also the IP application software and CPU utilization.

These are what I found in internet. The only difference between these two examples is Cell ID. One is what we usually call (sub 6 Ghz) and the other is what we usually call millimeter wave. 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). 5G UE The way to calculate the ideal throughput using these factors are explained in "Throughput Calculation Example" in Quick Reference page. 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. Time and frequency densities of PTRS are adapted to signal-to-noise-ratio (SNR) and scheduling bandwidth. 4G/LTE - Access Control Throughput Calculation - TDD; Throughput Calculation - From UE Cateogory; Throughput : Common It is equivalent to LTE PDCCH area (the first 1,2,3,4 OFDM symbols in a subframe). 306 document for more information on 5G NR data rate calculation. As you know, NR use various types of subcarrier spacing (Numerology). According to 38. Even though these two equation look very differently but if you take a closer look you would notice the difference is very small. In 5G, time and frequency resource allocation of physical channels or signals are very flexible comparing to LTE Due to this high flexibility, it is often tricky to understand how the configuration of such frequency and time domain works. So, simply put, 'Spectrum Sharing' in DSS would mean Spectrum Sharing between LTE and NR. 7 LTE level throughput (e. When you say 'Trasport Block Size', it means the size of the array 'a' at the first step of the following process. it indicates the size of the Initial Bandwidth Part. I've revised the code just a little bit for my own purpose. Definition of BWP. Source : 5G NR-Light (RedCap): Revolutionizing IoT - Qualcomm. I found a couple of examples of the max throughput calculator as listed below. 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. What are the multiple radio access technologies that wants to share a spectrum. The difference between this example and previous example is system bandwidth. 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. Largest component carrier bandwidth not smaller than 80 Mhz for at least one numerology is supported ([1]) Waveform is based on OFDM ([2]) This site is for everything on 4G/LTE Search in ShareTechnote LTE Band/BW. With this large subcarrier spacing, this waveform can be much more robust than LTE/LTE-A in terms of phase noise. g, Measurement Report RRC message), it gives a positive integer value, not the dBm value. g, configured scheduling, SFI and introduction of cancellation, interruption etc) which may lead to too much complication and unstability of the 5G MIB / SIB in Detail. So general tips for max throughput case would be "Use CFI = 1 for Cat 4 or higher max throughput case". This plot is automatically generated by AZQ Reporting tool and I just did some cosmetic touch on the chart. WiFi. So the QoS architecture is more flexible (probably more difficult to understand ?) to provide appropriate service for all those application. In 3GPP NR Specification, not so much details are explained about SplitBearer mechanism. 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. One obvious difference you may notice is to compare LTE QCI and NR 5QI table, and just compare the length of the tables. Then let's think of 'Dynamic' part in DSS. Following plot is from the data captured by a drive test tool Azenqos Drive Test tool (AZQ Android). 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. When you get the RSRP value from measurement report (e. 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. Comm. What is the maximum bandwidth we use for LTE as of now ? (May 2013) It is 20 Mhz assuming Single Carrier. Explanation on how such a frequency domain allocation (frequency domain resource location) works is the main purpose of this note. If you know the MCS index and number of RBs, you can calculate the throughput for that specific MCS idex and RB as follows: The major difference from LTE RSRP is that NR RSRP is measured from the reference signal in SSB whereas LTE RSRP is measured from CRS(Cell Reference Signal). 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 What is the maximum bandwidth we use for LTE as of now ? (May 2013) It is 20 Mhz assuming Single Carrier. 5 GHz & mmWave | Sneed finds N41 & N261 in the Cle! (Nov 2020) T-Mobile 600 MHz LTE & 5G, 2. What would this mean ? Definition of BWP. The PHICH position is the 'orange' resource elements in the first symbol. Throughput Calculation Example - FDD. 4. When stransmitted in UE specific search space and meets following criteria; the total number of different DCI sizes monitored per slot <= 4. Source : RedCap - expanding the 5G device ecosystem for consumers and industries - Whitepaper - Ericsson This is same concept as RBG size in LTE Resource Allocation Type 0. The subframe for antenna 0 transmitted the reference signal allocated for antenna 0 and does not transmit any signal at the reference signal allocated for antenna 1. And this trend would not change much in future generation (e. So, in stead of directly jumping into max throughput test, increase the throughput step-by-step and check CPU utilization (e. Time Domain Symbol Location Time domain symbol location of PDSCH PTRS is specified by 38.
