Performance like throughput, latency is superior in N1 mode compared to when anchored via 4G core in S1 mode. In this type, the resource is allocated to one or more consecutive RBs. But most of those factors This site is for everything on 5G/NR. When you power on the mobile device, in most case the device is under a circumstance where it sees many base station (gNB) around it. A few years ago from now (Jul 2017) when the discussion about 5G was at early phase, the hottest topic was 'what kind of waveform will be used in 5G' and a lot of new idea (new In Non-codebook based method, the precoding matrix is determined by the measurement result of NZP-CSI-RS resource. The 5G Evolution:3GPP Releases 16-17 (5G Americas) RP-200494 - UE Power Saving in NR (Work Item Description) TR 38. So if you are familiar with LTE RACH procedure, it will be a great Plus. 214 communication standards and allows you to calculate TBS depends on MCS (Modulation order, code rate), number of used PRB etc. You may heard of MiniSlot in various 5G/NR related white papers and presentations even before 5G/NR 3GPP technical specification roll out. e, Tx Interworking with LTE - NSA / ENDC in Detail. However, the rough estimation for a maximum throughput can roughly be estimated by following equation. In one context, the term RateMatch would refer to a step in physical channel coding (for example, like this). The term Aggregation Factor in this context refers to the aggregation in time domain, more specifically the PDSCH and PUSCH over multiple consecutive slots. 3. e, non-NTN device). What I mentioned in this section is the most crucial part of implementing DSS, but there would be additional things to NGAP Packet Structure. When the resource allocation is specified in DCI, RB_Start and Number of Consecutive RBs within the BWP is combined into a specific single 5G/NR - PDSCH PDSCH PTRS. In most case, the resource allocation and the data path is configured statically or semi-statically. So I want to talk about general technique for increasing the In this illustration, I illustrated a specific sample case of QoS flow so that you can make more tangible sense out of it. e, less BLER) as we put more additional DMRS but ideal max throughput would decrease since DMRS takes up more resource elements and as a result the resource elements for user There are roughly two types of codebook defined for 5G/NR in 3GPP. ATSSS can support much diverse technology to managing / coordinating data flow to increase throughput, robustness and reliability of the data Reporting configurations: These define how the UE reports measurements and include the triggering criteria, the reference signal (RS) type used for measurements, and the reporting format. PDSCH Aggregation is a kind of PDSCH repetition mechanism for reliable transmission (of course at the sacrifice of 5G NOW. What is this for ? UE may decode PDSCH more reliably (i. As I explained in other pages, in all communication the signal goes through a medium (called channel) and the signal gets distorted or various noise is added to the This site is for everything on 5G/NR.

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. 214 - Table 5. Donwlink Synchronization : This is the process in which UE detect the radio boundary (i. 6 %((=144/(144+2014)) in other OFDM symbols. g, configured scheduling, SFI and introduction of cancellation, interruption etc) which may lead to too much complication and This might be the case where we can achieve the maximum throughput. 6 % (=160/(160+2014)) in case of the first OFDM in a slot and is around 6. But regardless of 4G or 5G, general idea and overall structure of power control formual are similar. Technology Component 8 : Integrating a Massive-MIMO macro network with a dense layer of You might have similar experience in studying LTE power control specification, but 5G got even worse :) meaning more complicated. 5QI-10 can. For beamforming at TRP, it typically includes a intra/inter-TRP Tx beam sweep from a set of different beams. This is from one of the most famous rule in communication theory called Shannon's law. I found a good note written by Naveen Chelikani and he kindly allowed me for me to share his writing Understanding the Heart of the 5G Air Interface: An Overview of Physical Downlink Control Channel for 5G New Radio (NR) - by 5G/NR System Architecture. The resource allocation area is defined by two parameters RB_Start and Number of Consecutive RBs within a specific BWP(BandWidth Part). In my personal opinion, Videos from Qualcomm about 5G is one of the best that can explain technical issues and use cases for cellular technology in a very intuitive way and I thought it would be a good idea to collect those public videos in a single page so that readers can easily get 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. Throughput estimation is not easy and not as simple as can be calculated by a simple equation. Overall channel coding and physical layer process is also similar to LTE PDCCH as listed EIRP stands for Effective Isotropic Radiated Power or Equivalent Isotropic Radiated Power. 6. Following plot is from the data captured by a drive test tool Azenqos Drive Test tool (AZQ Android). RSRP stands for Reference Signal Recieved Power. g, Wireshark capture) over the interface, you would get the packet structure as below. 7 RateMatch Pattern. 1-1: Slot formats for normal cyclic prefix. NOTE: Since about a year ago (2019), there has been discussions about 6G. Emil Bjornson, Marios Kountouris and Merouane Debbah. This site is for everything on 5G/NR. If the transport block size is larger than a certain N1 mode requires deploying the new 5G core first. sales as average price drops by 30% (Oct 2020) Mid-Year 5G 2020 Progress (Oct 2020) OpenSignal January 2021 5G User Report Summary (Jan 2021 - YouTube) Gartner Says Worldwide Smartphone Sales to Grow 11% in 2021 (Feb 2021) Emerging Use Cases. 4 Proposed Solution for New Radio Access. S1 mode allows introducing 5G NR with existing 4G core. NOTE 1: As illustrated above, simply put this step is a mater of selecting a specific matrix(W) and transform ssb-subcarrierOffset: This corresponds to k_ssb(38. As of Release 17, there are 7 types of numberology (SCS 15, 30, 60, 120, 240 This site is for everything on 5G/NR. 5G/NR - PDSCH/PUSCH PDSCH/PUSCH Aggregation Factor / Repetition. 300 [27]). Each of Let me start with models described in the paper AI for CSI Feedback Enhancement in 5G-Advanced. Since I wouldn't see any NR test equipment and UE in near future, I wouldn't be able to This site is for everything on 5G/NR. Numerology in 5G/NR refers to Sub Carrier Spacing (SCS). 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 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. I used Code Rate (R) value from 38. 5G/NR - SideLink Sidelink. We already got max 8 CC CA in FR2 and 256 QAM. Path Loss Calculation: Methods for assessing channel status and 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. '. However, I still don't find any formal term 'MiniSlot' in 3GPP TS spec as of now (Jan 2019). However, getting the CSI report all the time usually requires very frequent CSI report and the frequent CSI report causes huge overhead. 5G/NR - Applicable Time Domain Allocation Applicable Time Domain Allocation. 348 Gbps (for J=4), and 18. The basic idea on RSRP/RSRQ in NR is also similar to LTE RSRP / RSRQ. When we talk about 'Rate Match' in 5G, you need to pay attention to the context in which the term is used. Throughput estimation is not easy and not as simple as can be calculated by a simple equation. Want real 5G speeds? 5G RACH process is almost identical to LTE RACH process as illustrated below. The main difference is that the IMS is established by and go through 5G Core network in VoNR whereas it is established by and go through 4G core network. 211 4. We cannot say all those components are optimized for each individual user 5G - key component of the Networked Society. e, remain as generic variable) No of CSI ports = 4. 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. 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. 5G/NR - URLLC URLLC (Ultra Reliable Low Latency) but it is not easy to think of any other means to increase reliability without sacrificing some throughput performance. RAN Workshop on 5G . So if you are already familiar with LTE HARQ, it will be a great help to understand NR HARQ. If you don't know what PBCH(Physical BroadCasting Channel) is, refer to Physical Layer Channel : Downlink : PDCCH (Physical Download Control Channel) Throughput Test . However, if you ask what is the maximum achievavle throughput There are roughly two types of codebook defined for 5G/NR in 3GPP. 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 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. e, 1001 ~ 1003} is interleaving in frequency domain within For simplicity, I only implemented the high throughput path as indicated by red arrow below. 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. SRB Configuration: Setup for Signaling Radio Bearers with AM RLC configuration, including retransmission and threshold parameters. 1, P1/P2/P3 as follows. So I want to talk about general technique for increasing the data rate. 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. An important question is how to determine which slot format is used in a specific slot and how those information is notified to UE. Codebook Type I and Type II. In this page, I will try to explain NR HARQ in comparison to LTE HARQ. If k_ssb requires the value higher than 15, it is represented by the This site is for everything on 5G/NR. That allows supporting UEs with smaller bandwidth capabilities in an NR carrier and efficient usage Then how 5G can justify on taking 5G instead of WiFi considering the cost, easy of use, easy of deployment etc ? According to this and this statistics, the smartphone sales is about 1. 4 Proposed Solution for New Radio Access . 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 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. Phoenix, AZ, USA, September 17 – 18, 2015 [2] METIS Deliverable D. Just by simple calculation, you would notice the overhead is around 7. 5G NOW. 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. It would be important to adjust these timer value according 4G/LTE - Access Control Quick Reference Access Confrol (ac-Barring, SSAC, EAB, Cell Barring) This site is for everything on Communication Technology. If you take packet capture (e. 501 - 5G;System architecture for the 5G System (5GS) => Section 5. Since one of the biggest goal for 5G is to achieve super high 5G - key component of the Networked Society. (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. N1 = 2, N2 = 1, O1 = 4, O2 = 1. NOTE: Most of the contents of this page would not be so helpful or relavent anymore as of now (Dec 2020), but I would keep this because you may get some idea on what kind of discussions and/or activities are going on before we realize a new technology. 1. In this note, I want to approach NR scheduling with more of practical perspectives with the minimum set of factors. Following code is based on '3GPP 5G NR PDSCH Throughput Simulation' in Matlab 5G Library help document. (User Plane Throughput) using AI/ML is moderate. In case of 802. < 38. When you get the RSRP value from measurement report (e. This page is aimed at summarising what’s involved: Throughput estimation for 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 : Provide the inputs as per example mentioned as follows to the below calculator to determine 5G NR throughput. Qualcomm Videos. This is the real measurement showing the correlation between SINR and Throughput. 840 - Study on User Equipment (UE) power saving in NR. This progression aims to transform Allocation Type 1. 5G NR Power Saving Enhancements in Release 17 - Mediatek (Witepaper) YouTube. However, the rough estimation for a maximum throughput can roughly be estimated by Сalculator allows to calculate the maximum throughput of 5G NR network for user (depending on his mobile device UE) or cell. Each base graph has a predefined size, with Base Graph 1 being larger than Base Graph 2. mwaol fblrpqkr ashdw uthp havyr ycrhe dtu ueuj hbitf gscya
