Power Control" and if you want to have some hands-on experience of these, I would recommand you to try some test items on 36. 840 - Study on User Equipment (UE) power saving in NR [4] In 5G New Radio (NR), maximum output power levels are categorized into different power classes to support various use cases and device types. ; Cell Status: The cell is marked as barred, meaning it's not available for use by ordinary NB-IoT devices (i. In this page, I will describe on NR MAC and try to explain in This site is for everything on 4G/LTE. However, the rough estimation for a maximum throughput can roughly be estimated by following equation. Even though the detailed procedure is a little different, highlevel concept of blind decoding is same in LTE and NR). LTE Band/BW. 5QI stands for 5G QoS Identifier and it is equivalent to QCI in LTE. This is the real measurement showing the correlation between SINR and Throughput. So if there is some way to preprocess the data in such a way that UE can Downlink Data transmission Process . From Rel 12, 3GPP defines (support) 256 QAM in Downlink. Internal Search 3GPP Guru. We have MU-MIMO in current In LTE, PUCCH are usely placed at an extrem side of the channel bandwidth (i. 1 5G Waveform Candidate Selection . 5G/NR - MU MIMO MIMO for more than 2 UEs simultaneously as illustrated below. There has been LTE equivalent of RedCap which targets mid-tier IoT devices (not as much reduced capability as LTE BL/CE or NB-IoT). I think this will be a keyword (but somewhat confusing word) for a while at the early stage of 5G/NR RF/mmWave Measurement. In WiFi Offloading, only one possible scenario of data transfer was Throughput Calculation Example - FDD . What is this for ? It is a special physical signal for uplink radio channel estimation. DL Control LTE SS Block vs NR SS Block. Unfortunately this would result in If I define LTE Integrity Protection Procedure with this logic, it would be "a process that convert 'K' value from USIM into PDCP MAC-I and NAS MAC(Message Authentication Code)". Meaning of each parameters in This site is for everything on 4G/LTE. (This is similar to PDCCH which carries DCI (Downlink control information)". LTE SS Block vs NR SS Block. Physical Layer Processing is pretty complicated issues. It means that we would not see any drastically different waveform in 5G (at least at early stage) even though This site is for everything on 4G/LTE. For the specific example of generated PSS, refer to Matlab : Toolbox : LTE : PSS page or PSS I haven't seen these names in 3GPP, but LTE-M1 seems to indicate LTE 1. This logic applies at least to 4G and 5G. This site is for everything on 5G/NR. Features. 4G LTE Cell ID (ECI) Calculator. As far as I remember, most part of evolution in cellular communication so far has been focused mainly on increasing the throughput. sharetechnote. This is 2 x 2 and 2 layer case. I haven't seen these names in 3GPP, but LTE-M1 seems to indicate LTE 1. 4G/LTE - Timers T300 4G/LTE - PHY Channel PUCCH Format . N/A. When we talk about 'Rate Match' in 5G, you need to pay attention to the context in which the term is used. TDD throughput calculation is very similar to FDD case as you see below. Overall functionality and structure of MIB / SIB of NR is almost same as LTE, but there is one major differeces between NR and LTE. 1-1: Transport block size table as in legacy LTE. There are several factors that is critical to determine the throughput can be summarized in an illustration as shown below. 340). Depending on what kind of information the UCI in PUCCH carries, PUCCH is classified into various formation as follows. Overall description of cell selection process is described in 38. You see there is pretty much gap between the two plots. Power Control" and if you want to have some hands-on experience of these, I would Characteristics of 5G HARQ. 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 4G/LTE. LTE - Low Throughput Application . This enables suppression of phase 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. D3. 2. In this note, I am going to try to keep track of somes challenges on 5G in terms of technology and business perspective. 5G NR Throughput Calculator | 5G NR Throughput Formula ; 5G NR Throughput calculator; Reference. RI (Rank Indicator, Rank Index) To have clear understanding of RI, you have to understand the detailed concept of MIMO, Channel Status This site is for everything on 5G/NR. In LTE (actually all other techology except NR), all the SIBs are broadcast periodically regardless of whether UE want it or not. 5G/NR - Rate Match Pattern RateMatch Pattern. Unlike other layers, it would be very difficult for you to understand the details clearly unless you This site is for everything on 4G/LTE. This page is only to show you the overall logics and visualization for various LTE physical layer channels. in this case most of UE fails at PDSCH decoding and report HARQ NACK causing PHY layer retransmission. 213 - 5. So the description in this page would be almost identical to the LTE Cell Selection page. 5G TRS, or Tracking Reference Signal, is a key component in 5G wireless technology, primarily used for beam management. 10 ms radio frame, 1 ms sub frame. 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. But being ON all the time would drain the battery. Novel Wake-up Scheme for Energy-Efficient Low-Latency Mobile Devices in 5G Networks . 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 DCI in Detail. More formal definition of these process are stated in 38. I haven't made any effort for effiecient code. 211 - 6. In LTE 3GPP specification, typical three types of Fading profiles are defined as follows. 4G/LTE - Throughput Throughput Calculation - TDD . Considering the 5G data rate will be much higher than the final stage This site is for everything on 4G/LTE. At least as of now (Oct 2021), the industry seems to keep the This site is for everything on 4G/LTE. Generating PSS with default Matlab function In case of LTE as an example, we use the method described as shown below. 5G/NR System Architecture is almost same as LTE System Architecture. The difference between M1 and legacy LTE lies in mapping between I_MCS and I_TBS and the possible range of I_MCS. 5G/NR - Measurement Report Those reference signals in LTE is structured relatively simple way, so the configuration in RRC message is relatively simple. YouTube 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. The exact PSS symbol calculation is done by the following formula as described in 36. 5G/NR - EIRP EIRP. Following is an example of DCI 0_1 transmitted by the gNB. We already got max 8 CC CA in Throughput Calculation - From UE Cateogory . PTRS is used for tracking the phase of the local oscillator at the receiver and transmitter. Not for deep-dive into the details, just tracking high level descriptions on various challenges. That is to develop a full stack protocol that enable direct communication between UEs without getting any cellular network involved. 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. Frame Stracture. Drive Test . Throughput Calculation - FDD; Throughput Calculation - TDD; Tracking Area; Transmission Mode; TTI Bundling You might have similar experience in studying LTE power control specification, but 5G got even worse :) meaning more complicated. 2-4: Random access configurations for FR2 and unpaired spectrum using Matlab 5G Toolbox. 4G/LTE - CCE Index Following is a example of CCE index calculation (CCE Allocation for PDCCH) in real communication between UE and eNB NextGen Core : Core Network for Next Generation System. HOT KEY. 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 This site is for everything on 4G/LTE. It is determined by a complicated algorithm. Fading Channel Model Examples . The basic idea on RSRP/RSRQ in NR is also similar to LTE RSRP / RSRQ. When the data go through these interface, they get encapsulated by various tunnel protocol as in Figure 2 of Network Architecture and Interface This site is for everything on 4G/LTE. Then a question popped up in my mind. The predfined region in which UE perform the blind decoding is called Search Space. 4G/LTE - PHY Measurement RSRP, RSRQ, RSSI, SINR Interplay the signal quality is to achieve as much data rate as possible. FDD. . NTN. 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 Approximately data transfer rate of 5G NR can be calculated using the formula: The calculation is based on the 3GPP TS 38. That correlation can be expressed as follows. Go through following You might have similar experience in studying LTE power control specification, but 5G got even worse :) meaning more complicated. 212 - Table 7. DL Control Channel. A Few Related Keywords; 3D to 2D Presentation 5G MIB / SIB in Detail. 323 4. It is equivalent to LTE PDCCH area (the 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. 2G/3G. The key difference is 'number of subframes /sec' parts as marked in red. 802-6. 306 document for more information on 5G NR data rate calculation. In NR, the types of reference signal is synchronization signal/PBCH Reference Signal and CSI-RS (As you know, in NR there is no Cell Specific Reference There are much diverse preample format in 5G/NR comparing to LTE. LTE Band/Freq. Can Schedule 1 DL and 1 UL subframe at a time. For the specific example of generated PSS, refer to Matlab : Toolbox : LTE : PSS page or PSS with default Matlab function. 820 ( Ref ) Reference . NR also reports similar information The way to calculate the ideal throughput using these factors are explained in "Throughput Calculation Example" in Quick Reference page. Just try to go through this illustration whenever you have chance and try to have your own idea first. 1. But for MU-MIMO, we need to consider the In this illustration, I illustrated a specific sample case of QoS flow so that you can make more tangible sense out of it. So if we use this in LTE, we may be able to use GSM/GPRS spectrum for NB-LTE. In 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. 5G Tools for RF Wireless . I think one of the most widely adopted application of AI/ML in physical layer is for CSI report process. Speeds are based on theoretical throughput and vary based on In LTE UE capability information carries the information in roughly two large category : RF/Physical layer information and Feature Group (FGI). If you look into the downlink signal, you would notice that it is made up of many different components. In normal DL or UL subframe, TBS/subframe can be calculated in the same way as in FDD. This includes the main signal and co-channel non-serving cell signal, adjacent channel interference and even the thermal noise within the specified band. For example, Reference Signal, PDCCH, PDSCH etc. as of now (as of May,2013) is 2 x 2 MIMO. In case of 2 x 2 MIMO in LTE, each sub frame has different locations for reference signal for each antenna. LTE This site is for everything on 5G/NR. e, Tx 5G NOW. PDSCH Aggregation is a kind of PDSCH repetition mechanism for reliable transmission (of course at the sacrifice of throughput). These are what I found in internet. 5G/NR - Power Definition / Measurement Power Definition / Measurement. 11. PUCCH (Physical Uplink Control Channel) carries a set of information called "UCI(Uplink Control Information)". NR Power Class. Power Headroom = UE Max Transmission Power - PUSCH Power = Pmax - P This site is for everything on 4G/LTE Amarisoft TechAcademy. I think the 3GPP terms for LTE-M2 is NB-LTE according to This site is for everything on 5G/NR. For beamforming at TRP, it typically includes a intra/inter-TRP Tx beam sweep from a set of different beams. This progression aims to transform the landscape of digital communication by enhancing current services like Enhanced Mobile Broadband (eMBB) and 4G/LTE - PHY Channel PUCCH Format . 4 Mhz, 3 Mhz, 5 Mhz, 10 Mhz, 15 Mhz, 20 Mhz whereas C2K can only have single bandwidth of 1 If I define LTE Integrity Protection Procedure with this logic, it would be "a process that convert 'K' value from USIM into PDCP MAC-I and NAS MAC(Message Authentication Code)". 3G throughput (i. That is one of the reason why I wrote multiple pages for the same topic (CSI). PRACH Sequence and RACH Occasion - FR2, 120 Khz . In this case (based on RRC configuration shown above : 2 antenna ports, codebookSubset = nonCoherent, transform precoder = disabled, ul-FullPowerTransmission = not configured), precoding_info indicates the index in 38. Based on the LTE specification, an LTE system bandwidth can be any of 1. For now, you may get a little bit more detailed idea from LTE specification described in 36. 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. There are three types of Frame Structure : Type 1 for FDD, Type 2 for This site is for everything on 5G/NR. 3: Cell Selection Process and 5. LTE Power Control in LTE .
