Calculator is based on 3GPP communication standards and allows you to calculate the maximum throughput of 4G LTE networks. LTE level throughput (e. (This kind of focus hasn't been changed much until mid 2013) As we call 4G as LTE, there must be similar name for This site is for everything on 5G/NR. UE does not need to do blind search for SSB since the frequency, subcarrier spacing etc are all configured by LTE RRC Connection Reconfiguration message It means you have to measure the whole set of test items for multiple different system bandwidth which multiplies the measurement time and parameter settings in measurement equipment. 5G/NR - Massive MIMO This might be the case where we can achieve the maximum throughput. If you don't know The difference between this example and previous example is system bandwidth. 2G/3G. The maximum configuration that is specified in 3GPP as part of final goal of LTE advanced is 8 x 8. What is this for ? It is a special physical signal for uplink radio channel estimation. This is about one of NR deployment options where LTE work as a master and NR work as a secondary cell (In 3GPP terms, this is about EN-DC (EUTRA-NR Dual Connectivity) / MR-DC with EPC as described in 37. ) allows for a "building block" approach, where components can be flexibly combined to suit various system configurations and radio technologies. It means that a considerable portions of the data were failed to get properly decoded by 4G/LTE - Throughput Throughput Calculation - TDD . Refer to this page for estimating RF spectrum (RF bandwidth). LTE UE Category. CyclicPrefix = 'Normal'; This site is for everything on 5G/NR. At high level view, BWP would be a There are much diverse preample format in 5G/NR comparing to LTE. However, as you see in 'Agreed Item' page, it seems that 5G (NR) waveform will be exactly same as 4G(LTE) waveform or very similar to it. 5G/NR - PUSCH Calculate pr0,pr1,pr2,,pr(L-1) using the sequence cr0,cr1,cr2,,cr(K'-L-1) and g_CRC24B(D) (LTE DL Precoding and 5G Downlink CSI RS Codebook) LTE Band/BW. Ideally I think I can summarize the equation for Tx Power (UE Tx Power) of any uplink channel can be summarized as This site is for everything on 5G/NR. First Calculate N'_RE using following formula. Following is the table that I converted the downlink portions of Table 4. LTE Band/BW. 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 Interworking with LTE - NSA / ENDC in Detail. 8 Carriers (1 PCC + 7 SCC) Waveform. Beam Width: This refers to the width of the main lobe, often defined by the points at which the signal strength falls to half its maximum value, which is where the term "3dB Bandwidth" comes into play. 211 -Table 6. However, in NR there are two different types of SIBs. Guidelines for Determining the Effective Radiated Power Antenna Fundamentals 1 Propagation; Antenna Fundamentals 2 Directivity; Antenna Fundamentals 3 Bandwidth; Antenna array part In 5G New Radio (NR), maximum output power levels are categorized into different power classes to support various use cases and device types.

This page is only to show you the overall logics and visualization for various LTE physical layer This site is for everything on 4G/LTE. One thing for sure for 5G would be that the required data throughput for 5G will be much higher (probably tens of Gbps) than 4G. 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. QoS can be used to allocate more network resources to the autonomous vehicle traffic, but it may not be sufficient to provide the necessary level of performance and service. 5G/NR System Architecture. It corresponds to control region in LTE subframe, but the difference is that frequency domain resource allocation in 5G Coreset is configurable whereas in LTE the contron region always takes up the full channel bandwidth. 5G/NR - Measurement Report Those reference signals in LTE is structured relatively simple way, so the configuration in RRC message is relatively simple. 5G/NR - DCI 5G DCI in a Nutshell . I would suggest you to go through LTE SRS first The higher RSRQ is, the better the signal quality is if Bandwidth and number of RB allocation is same. NR-Light, now officially terms as Reduced Capability (RedCap) in 3GPP NR Rel 17, is designed to function as LTE M1 /LTE NB IoT. Unlike LTE PUCCH that is located at the edges of the carrier bandwidth and is designed with fixed duration and timing, NR PUCCH is flexible in its time and frequency allocation. 4G/LTE - PHY Processing LTE Timing Sync : Cyclic Prefix Correlation . Then the problem (confusing part) is how to specify the In 5G, time and frequency resource allocation of physical channels or signals are very flexible comparing to LTE; (Numerology). I found a couple of examples of the max throughput calculator as listed below. But for MU-MIMO, Estimating the Maximum Throughput and 5G Capacity for modern Wireless Networks is complex and requires understanding of the 5G standards. 5G/NR ATSSS looks to be an envolved version of WiFi Offloading/ePDG that we used in LTE. The 5G Evolution:3GPP Releases 16-17 (5G Americas) RP-200494 - UE Power Saving in NR (Work Item Description) TR 38.

(configure) some parameters for the The Extension from IMT-2020 (5G) to IMT-2030 (6G) represents an ambitious leap in telecommunications technologies, seeking to build upon and expand the capabilities established by 5G networks. UE does not need to do blind search for SSB since the frequency, subcarrier spacing etc are all configured by LTE RRC Connection Reconfiguration message NOTE: This note is about a tempary 5G specification that was implemented and tried before 5G specification is finalized. 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 Throughput Calculation Example - FDD . Due to this, the symbol length in this frame can be 4 times shorter than LTE/LTE-A symbol length. For the general description of PTRS, I would just quote the explanation If transmitted, PTRS is always associated with one DMRS port and is confined to the scheduled bandwidth and duration of PDSCH/PUSCH,. Even though these two equation look very differently but if you take a closer look you would notice the difference is very small. Max Throughput Estimation; Method 1 : based on 38. The predfined region in which UE perform the blind decoding is called Search Space. Amarisoft TechAcademy. 322-5. Matlab Toolbox - 4G/LTE % SSS first and then calculate PCI (Physical Cell ID) from the PSS,SSS. 20 Mhz BW Case : A = Occupied Subcarriers (including DC) x 15 Khz = 1201 x 15 Khz = 18015 Khz = 18. In addition, it can use different subcarrier spacing within the same channel bandwidth depending on type of channel/signal (e. When stransmitted in UE specific search space and meets following criteria; the total number of different DCI sizes monitored per slot <= 4. NOTE : It is required to have Matlab 5G Toolbox option to run this script . This page is a kind of extension of previous tutorial : LTE UL(SC-FDMA) Demodulation (without DMRS Analysis). it indicates the size of the Active Bandwidth Part This site is for everything on 5G/NR. It is not provided in the form of predefined table as in LTE. 4 slot for LTE-M1 is called 'Narrowband'. So if the system bandwidth of LTE channel changes, number of the channels (sub carriers) changes but the space between channels does not change. There are much diverse preample format in 5G/NR comparing to LTE. g, PDSCH) or uplink This site is for everything on 5G/NR. NOTE: What will be described in this page is mostly based on early discussion of 5G Waveform candiate before 3GPP activity started. Of course, this type of scheduling can be a limiting factor for throughput, but it can be useful way depending on situation. Allocation Type 1. So general tips for max throughput case would be "Use CFI = 1 for Cat 4 or higher max throughput case". 4 Mhz, 3 Mhz, 5 Mhz, 10 Mhz, 15 Mhz, 20 Mhz whereas C2K can only have single bandwidth of 1 What is the maximum bandwidth we use for LTE as of now ? (May 2013) It is 20 Mhz assuming Single Carrier. What is it ? At least for now, the official name for 5G is NR that stands for New Radio. 5G(NR) FRC LTE LTE Adv 5G/NR 6G .

UE does not need to do blind When the first talk about 5G started and some of prototyping test result came out, the focus was mainly around throughput. I keep this as a reference showing how a new technoligy is being developed and evolved. The subframe for antenna 0 transmitted the reference You may think NR(5G) waveform is much simpler than the LTE waveform. 5G/NR - SRS SRS in a Nutshell. But regardless of 4G or 5G, general idea and overall structure of power control formual are similar. 2-1 into frequency Bandwidth just to give you the idea In NR, there is a mechanism to define a portions of frequency region within a given band and let UE and gNB communicat within the portion. It is same as the max throughput of SU-MIMO, but the max throughput for the The first main factor you can think of is 'how many carriers are used for the data traffic'. Even though the detailed procedure is a little different, highlevel concept of blind decoding is same in LTE and NR). As you know, NR use various types of subcarrier spacing (Numerology). For beamforming at TRP, it typically includes a intra/inter-TRP Tx beam sweep from a set of different beams. In this page, I will describe on NR MAC and try to explain in the comparison to LTE MAC whenever it is possible. As in LTE, the most important criteria on Power Measurement is around RSRP, RSRQ. SubcarrierSpacing = 30; % 15, 30, 60, 120, 240, 480 (kHz) gNB. It is used by the mobile device to connect to the packet data network and access the internet and other services. Since this is subframe 0 (NSubframe = 0), you see PSS, SSS. Matlab Toolbox - 4G/LTE PHICH . 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. In this case, you may need to consider following factors into the channel model. 4 Mhz, but legacy LTE System BW with which LTE-M1 operate can be wider than 1. NDLRB = 25; enb. MAC CE - Buffer Status Report MAC CEs . This way of decoding is called Blind Decodinig (See LTE Blind Decoding if you want to know of the concept in more detail. Fundamental logic of the GAP setting is same as in LTE PRACH Sequence and RACH Occasion - FR2, 120 Khz . 5G/NR - Resource Grid This is same as LTE.

It means that we would not see any drastically different waveform in 5G (at least at early stage) even though In 3GPP NR Specification, not so much details are explained about SplitBearer mechanism. TDD throughput calculation is very similar to FDD case as you see below. This progression aims to transform This site is for everything on 5G/NR. (This kind of focus hasn't been changed much until mid 2013) As we call 4G as LTE, there must be similar name for In NR, there is a mechanism to define a portions of frequency region within a given band and let UE and gNB communicat within the portion. 2 ms (5 times shorter than current LTE) Synchronization Signal . % First you have to define properites of a eNodeB. 5G/NR - UE Capability bandwidth information, Bandwidth(for single carrier) and Bandwidth Combination(for Carrier Aggregation), MIMO, Subcarrier Spacing etc. enb. 5G MIB / SIB in Detail. In 5G, time and frequency resource allocation of physical channels or signals are very flexible comparing to LTE; (Numerology). I think the purpose and concept of BWP is very similar to NarrowBand in LTE M1. 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 The message summarizes configuration details for an NB-IoT system's SIB1, focusing on parameters relevant to a non-terrestrial network (NTN) Network Identity: Specifies the MCC (001) and MNC (01), indicating the operator's country and network. For example, in LTE (as you see in LTE Physical Cell IDpage), we can derived Physical Cell ID from LTE Sync signal. 5G/NR - SideLink Sidelink. Subcarrier Spacing. 5 GHz & mmWave | Sneed finds N41 & N261 in the Cle! (Nov 2020) T-Mobile 600 MHz LTE & 5G, 2. Time and frequency densities of PTRS are adapted to signal-to-noise-ratio (SNR) and scheduling bandwidth. 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. Max Number This site is for everything on 5G/NR. In LTE, the main idea to achieve the low cost solution is. We are doing various kinds of throughput related test in the lab, but the most meaningful test is to test in the field like downloading / uploading files in out doors sometimes walking along the This site is for everything on 5G/NR. Active Antenna Demo for 5G by Nokia and Mitsubishi (Apr 2015) [1] 5G live test demo: Multipoint Connectivity with Distributed MIMO (May 2015) [2] MediaTek 5G 28Ghz mmWave Technology At #MWC18 Matlab Toolbox - 5G/NR SS/PBCH Block . As mentioned in Overview page, one of the critical differences in terms of waveform design between 5G Pretrial and current LTE is that in 5G Pre Trial the subcarrier spacing is 75 Khz as opposed to 15 Khz This site is for everything on 4G/LTE. (I already Category M(LTE-M) Recently (as of Sep 2015) you might have seen two obvious directions of LTE evolution. < Code Rate vs MCS in LTE > Followings are the code rate for each MCS in LTE assuming that the System Bandwidth is 20 Mhz and 100 RBs are allocated and 256 QAM is not supported. Next Calculate the total number of REs for PUSCH as follows. Approximately data transfer rate of 5G NR can be calculated using the formula: The calculation is based on the 3GPP TS 38. NR Power Class. The PHICH position is the 'orange' resource elements in the first symbol. So, in stead of directly jumping into max throughput test, increase the throughput step-by-step and check CPU utilization (e. In TR 38. NB-IoT. Of course, this type of scheduling This site is for everything on 5G/NR. g, Measurement Report RRC message), it gives a positive integer value, not the LTE SS Block vs NR SS Block. As LTE evolves, we got increasing number of measurement gap definition and with the introduction of NR, this list got exploded as below. These 1. 323 4. 817-9. 5G/NR - PDSCH PDSCH (Physical Data Shared Channel) in a Nutshell . Considering the 5G data rate will be much higher than the final stage In 5G, this step is simply labeled as "RRC Reconfiguration". % Code rate used to calculate transport block sizes. 0. Case 2 : I_MCS is in 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. TRS in 5G plays a crucial role in maintaining time and frequency synchronization, particularly in high mobility scenarios, distinguishing it from CSI-RS, which is more aligned with beam management and channel quality assessment Theoretically, they can be any technologies, but in practice we usually mean NR(5G) and LTE(4G). 3GPP TS 23. 2 PDCP entities. 300 - NR and NG-RAN Overall description; Stage-2 => Chapter 12; 3GPP 23. For the BSR functionality, Regarding RLC layer data volumn calculation, there are several factors to be used to calculate the data volumn as listed below (based on 38. 11ad). Of course there is no problem with the current LTE to work for such a low throughput application. In case of 2 x 2 MIMO in LTE, each sub frame has different locations for reference signal for each antenna. I tried to make it as practical as possible based on 3GPP higher layer specification. Data Throughput UMTS - UE Catetories : This site is for everything on 4G/LTE Amarisoft TechAcademy. 5G - Current Activities They claims that they achieved 10 Gbps throughput in 11 Ghz, 400 Mhz BW with 24 antenna. 1, P1/P2/P3 as follows. This is not a new concept. 5G/NR - MCS/TBS/Code Rate Table 3 for Low Data Rate; TBS calculation is not as simple as in LTE. g, 100 Mbps and over) is pretty tough task not only for IP stack, but also the IP application software and CPU utilization. At the final stage of LTE advanced, we may be able to use max 100 Mhz using 5 carriers. 003 - (GSM);(UMTS This site is for everything on 5G/NR. 5G/NR - MU MIMO MIMO for more than 2 UEs simultaneously as illustrated below. That allows supporting UEs with smaller bandwidth capabilities in an NR carrier and efficient usage < Calculation of Available Resources > This section shows how to figure out the amount of resources that can be allocated for PDCCH transmission. 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. I have seen many issues even from LTE only cases in later 3GPP release in terms of processing UE capability information in both UE and network What is the maximum bandwidth we use for LTE as of now ? (May 2013) It is 20 Mhz assuming Single Carrier. Based on the LTE specification, an LTE system bandwidth can be any of 1. CodingType = 'LDPC'; % Set to 'LDPC' for 5G DL-SCH or 'Turbo' for LTE DL-SCH. For now, you may get a little bit more detailed idea from LTE specification described in 36. 5G Mobile mmWave Technology Evolution More formal definition of these process are stated in 38. {lte, nr, both} OPTIONAL Matlab Toolbox : 5G Library : PUCCH Format 0; 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 Some background of adopting this kind of design is briefly described in V-B of this paper as follows . Novel Wake-up Scheme for Energy-Efficient Low-Latency Mobile Devices in 5G Networks . This is the real measurement showing the correlation between SINR and Throughput. 5G numerology provides the foundation for the flexible and adaptive nature of 5G NR, enabling it to PDSCH Aggregation is a kind of PDSCH repetition mechanism for reliable transmission (of course at the sacrifice of throughput). 3. Largest component carrier bandwidth not smaller than 80 Mhz for at least one numerology is supported ([1]) Waveform is based on OFDM ([2]) 5G/NR - Power Definition / Measurement Power Definition / Measurement. (This kind of focus hasn't been changed much until mid 2013) As we call 4G as LTE, there must be similar name for 5G. it would be pretty obvious that the length of the subframe will be much shorter than the one we use in current LTE (1 Throughput Calculation - From UE Cateogory . 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 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 : Throughput estimation is not easy and not as simple as can be calculated by a simple equation. In terms of RF, you may need a little bit wider bandwidth than this because you need to consider the guardband. Generating This site is for everything on 4G/LTE. Power Saving Techniques for 5G and Beyond. NR-LTE co-existence, Note that this use case also exists for slot-based scheduling ==> See DSS page; Forward MAC . 15. Throughput Calculation - FDD; Throughput Calculation - TDD; Tracking Area; Transmission Mode; TTI Bundling In case of LTE as an example, we use the method described as shown below. com 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. Following the reconfiguration command, there is an acknowledgment step labeled "RRC Connection Reconfiguration Complete" in LTE and "RRC Reconfiguration Complete" in 5G, indicating that the reconfiguration process has been acknowledged by the UE. YouTube This site is for everything on 5G/NR. With this large subcarrier spacing, this waveform can be much more robust than LTE/LTE-A in terms of phase noise. What has been evolved in ATSSS comparing to WiFi Offload ? As the name implies, ATSSS can support First Calculate N'_RE using following formula. However, the rough estimation for a maximum throughput can roughly be estimated by following equation. 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. i) Use the narrowest BW Now you might be more interested in TRP measurement as we are getting into 5G/NR. High level concept of NR SRS is same as in LTE SRS and some of lower level parameter are very similar to LTE SRS lower layer parameter. This site is for everything on 4G/LTE Amarisoft TechAcademy. 7 It is recommended to read OFDMA/SC-FDMA sections to clearly understand throughput calculation in LTE. 4 Mhz System Bandwidth. Overall concept would be similar to TTI Bundling in LTE (in LTE TTI bundling is for Uplink. Matlab Toolbox - 4G/LTE A couple of important thing that you have to consider is that the sampling rate varies with system bandwidth and the number of samples within an OFDM symbol is different between the first symbol and the rest of symbols within a slot. Setting appropriate power classes is an important part of configuring both user equipment (UE) and base stations to ensure adequate coverage and quality of service while minimizing interference. As far as I remember, most part of evolution in cellular communication so far has been focused mainly on increasing the throughput. When we talk about 'Rate Match' in 5G, you need to pay attention to the context in which the term is used. 3dB Bandwidth: This is the width of the beam at a point 3 decibels below the peak power level. The only remaining technology to push up the throughput even further would be 2 codewords in both FR1 and FR2, 8 layers in FR1 and 400 Mhz This site is for everything on 5G/NR. WaveformType = 'CP-OFDM'; % 'CP-OFDM', 'W-OFDM' or 'F-OFDM' gNB. ; Cell Status: The cell is marked as barred, meaning it's not available for use by ordinary NB-IoT devices (i. 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. Performance like throughput, latency is superior in N1 mode compared to when anchored via 4G core in S1 mode. g, SSB, PDSCH etc) or BWP. 5G - RSRP 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). In NR (5G), it has been discussed on adding some additional information onto the sync N1 mode requires deploying the new 5G core first. Max Throughput Calculators. 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 You would see every detailed factors you need to consider if you want to calculate Code rate by hand. 5G/NR - Enhanced Massive MIMO In terms of throughput, we already have almost all the capability with Release 15. You can use this for DSS as well (for example, to avoid scheduling PDSCH in LTE PSS,SSS,PBCH region as explained in this note), You may heard of MiniSlot in various 5G/NR related white papers and presentations even before 5G/NR 3GPP technical specification roll out. Even thought LTE technology itself defines 6 different types system bandwidth, not all E-UTRA Band can support all of the 6 bandwidth. I would suggest you to go through LTE SRS first 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 . Ideally I think I can summarize the equation for Tx Power (UE Tx Power) of any uplink channel can be summarized as System Bandwidth. g, you can monitor the CPU utilization using Windows Task Manager) 5G TRS, or Tracking Reference Signal, is a key component in 5G wireless technology, primarily used for beam management. 4G/LTE - Fading The plot in the middle (labeled as 'PHY throughput with HARQ ACK' is the amount of data getting ACKED per second from the reiever PHY layer. 802-6. TRS in 5G plays a crucial role in maintaining time and frequency synchronization, particularly in high mobility scenarios, distinguishing it from CSI-RS, which is more aligned with beam management and channel quality assessment This site is for everything on 5G/NR. in this case most of UE fails at PDSCH decoding and report HARQ NACK causing PHY layer retransmission. 5G/NR - Frame Structure/Candidates Maximum channel bandwidth per NR carrier is 400 Mhz in Rel 15. 5G UE This Page provides information about 4G LTE Throughput calculator. ii) Phase Compensation after demodulation No official 3GPP document about 5G in Release 16 is available for now, but following is a list of maijor features of Rel 16 presented by Qualcomm in RAN 5 Meeting ( Sep 2015). 4G/LTE, 5G/NR; This site is for everything on 4G/LTE. Technology Component 10 : Multi-cell MU MIMO, decentralized transceiver design Explanation on how such a frequency domain allocation (frequency domain resource location) works is the main purpose of this note. I think one of the most widely adopted application of AI/ML in physical layer is for CSI report process. The amount of the resources for PDCCH is determined mainly by System Bandwidth and CFI which are the attribute of eNB. These are what I found in internet. 5G Mobile mmWave Technology Evolution Measurement GAP for LTE and NR . Definition of BWP. Open to Multi Carrier Operation. In LTE, the waveform generation It is equivalent to LTE PDCCH area (the first 1,2,3,4 OFDM symbols in a subframe). ; Efficiency: By grouping data into containers and frames, CPRI minimizes the In LTE, APN (Access Point Name) is used as an identifier for a specific network operator's packet data network. P-1: is used to enable UE measurement on different TRP Tx beams to support selection of TRP Tx beams/UE Rx beam(s). In Autonomous vehicles: Autonomous vehicles require low latency and high bandwidth to support real-time communication and decision-making. 6. 211 4. 5G/NR - PDSCH PDSCH PTRS. Case 2 : I_MCS is in Definition of BWP. PDSCH. Max Throughput Estimation. At the NOTE: What will be described in this page is mostly based on early discussion of 5G Waveform candiate before 3GPP activity started. 5G/NR - Rate Match Pattern RateMatch Pattern. It is the smallest unit of the resource grid made up of one subcarrier in frequency domain and one OFDM symbol in time domain. Channel Bandwidth is more for resource Following is the maximum number of RBs you can configure in RRC message and DCI. But the issue is not with the low throughput, but with some other constraints. One can refer following pdf which covers snapshot of 3GPP TS 38. The type of bandwidth supported varies depending of E-UTRA band as defined in 36. We are doing various kinds of throughput related test in the lab, but the most meaningful test is to test in the field like downloading / uploading files in out doors sometimes walking along the street or in driving because those are most closes related to real user experience. Internal Search Email . But BWP can be defined in more flexible fashion than Narrowband. Followings are agreed at RAN1 #85. 2-4: PDSCH DM-RS positions for double-symbol DM-RS > This site is for everything on 5G/NR. UE does not need to do blind search for SSB since the frequency, subcarrier spacing etc are all configured by LTE RRC Connection Reconfiguration message It is equivalent to LTE PDCCH area (the first 1,2,3,4 OFDM symbols in a subframe). 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. Using this PCI, the location of RS is Following is two example for RS display in a subframe with 1. LTE - Low Throughput Application . I will calculate the number of samples for other BW case by taking the ratio of FFT site of 20 Mhz and the FFT size of other BW. We have MU-MIMO in current LTE (TM5) and WLAN (802. chatTechnote. That is to develop a full stack protocol that enable direct communication between UEs without getting any cellular network involved. 4G/LTE - Throughput Throughput Calculation - TDD . Similarily in in NR the RBG size can only be 2,4,8 or 16 depending on the bandwidth of the BWP. PSS, SSS, ESS. There are roughly two approaches to estimate the max throughput. Drive Test . I made several examples of resource allocation and its ideal throughput as follows. This is about one of NR deployment options where LTE work as a master and NR work as a secondary cell (In 3GPP terms, this is about EN-DC (EUTRA-NR Dual Connectivity) / MR 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 This site is for everything on 5G/NR. Meaning of each parameters in We need to figure out the best configuration (Tx power, Resource Allocation) for each UEs to maximize the total throughput of a cell. The basic idea on RSRP/RSRQ in NR is also similar to LTE RSRP / RSRQ. Channel Bandwidth is more for resource allocation from the goverment, so there wouldn't be much of enhancement in 3GPP perspective. However, I still don't find any formal term 'MiniSlot' in 3GPP TS spec as of now (Jan 2019). Actually the calculation is too simple, [] This site is for everything on 5G/NR. 4G/LTE - PHY Processing PHY Processing . not my tool, but I think all of these tools are based on the fornula in 3GPP as summerized above. The key difference is 'number of subframes /sec' parts as marked in red. 5G/NR - NR Light/RedCap NR-Light/RedCap. EIRP Calculator. The throughput for a device working in a live network would vary at every moment as you can see this drive test. NTT DoCoMo confirms successful 10Gbps wireless test, clears a path to 5G (Feb 27,2013) NTT DoCoMo's vision of '5G' wireless: 100x faster than LTE, but not until 2020 (Oct 1, 2013) NTT DoCoMo This site is for everything on 5G/NR. Designed for simplified / low cost device ==> Same goal as LTE counterpart; Narrower bandwidth comparing to regular NR use case (eMBB), Theoretically, they can be any technologies, but in practice we usually mean NR(5G) and LTE(4G). At these points, the power is reduced to 50% (or The 5G Evolution:3GPP Releases 16-17 (5G Americas) RP-200494 - UE Power Saving in NR (Work Item Description) TR 38. This site is for everything on OpenRAN. The resource allocation area is defined by two parameters RB_Start and Number of Consecutive RBs within a specific BWP(BandWidth Part). sharetechnote. UMTS Throughput Release 99 HSPA One thing for sure for 5G would be that the required data throughput for 5G will be much higher (probably tens of Gbps) than 4G. as of now (as of May,2013) is 2 x 2 MIMO.
