Hi Team, Not able to understand what is "1. what is resource allocation slot 0 and 1"

In your calculation for 5G NR max data rate - UE radio access capability 38.306 there seems to be an error. If you take a single carrier with 2x2MIMO and 64QAM in FR1 with 30kHz SCS your calculation shows 62.6Mbps. It should actually be 876.4Mbps, shouldn't it? The numbers entered into the formula at the lowest line on that page are accurate, just the result is wrong. I believe you are missing the "14" from the Ts^mu part since your result is short by factor 14.

Can anyone tell me why my iPhone 8 Plus on AT&T continually jumps from good 4g signal to searching to poor Lte signal in my home location? We recently bought a surecall signal booster and still no better service...when 4g shows up it runs fast but usually lasts 30-60 minutes then it searches and finds a Lte signal it’s really fast but lasts half as long as 4g signal and even with Lte off it still becomes a signal jumping issue..we have 6 iPhones in the house and hey all do this constantly....the signal booster does work it took what was normally 2 bars to full bars now

Eran, I retrieved the LTE resource grid from a web site that has disappeared, as I indicate on top of the page; I am not the author; It is not easy to modify the javascript (Ctrl-U)

Hi dear, please can you remind me what means NR in 5G? thanks in advance

Helidri, the script replaces band 64 by the real band indicated in the extensions of the message, isn't it the case ?

Niviuk

Ambjörn, I have added a new table LTE bands for UE category ...

15 03 2018

helidri

I was testing the UE capabilities pretty viewer (http://niviuk.free.fr/ue_capa.php) and it turns out that it has a fault with band 64, when you put a UE EUTRA capability message with band 64, in the result shows the band 66.

Ambjörn

Hi! In the "E-UTRA channel bandwidths per operating band (36.101)" table, can it be added CAT-M and NB IoT applicability?

PHICH number of groups for the scenario: { DuplexMode: 'TDD' TDDConfig: 0 NSubframe: 0 CyclicPrefix: 'Extended' } Has half of the expected possible PHICH group indexes (compared to Matlab toolbox and spec equations).

To Hamza Bashir (sorry, niviuk, for answering instead of you). This resource grid is absolutely correct, no mistake. Please scroll down a little bit to my question at on 11/12/2017. The 36.211 specification really requires so.

20 02 2018

Hamza Bashir

Hi niviuk, Lte resource grid has been very helpful throughout my lte phy development. One thing I have noticed that when number of tx ports is set to one even then PDCCH reserves unused REs(probably for reference signals of second tx port ) which might never be the case.

Niviuk

Hi Vince, when indicating a bandwidth check value, I don't know yet the band, and therefore the min and max bandwidth of that band. The script detects band 5 for arfcn 2525, and limits internally the bandwidth check to the min(requested,supported), in that case 10MHz, and the test is ok.With arfcn 2450, and bandwidth check 20MHz, the test is ok as well for 10MHz; with arfcn 2449, the test fails. I have anyhow added an indication when the script internally limits the bandwidth

04 01 2018
12:43

Vince

Hi, I am not sure how the bandwidth check works in LTE EARFCN calculator. It looks like it does not check the 36.101 Table 5.6.1-1: E-UTRA channel bandwidth . For EARFCN 2525 (band 5) it does not reject a 20MHz bandwidth. BR, Vince

Andrew Kolomatski

Sorry, probably I found the answer. The clause "6.2.4 Resource-element groups" of the 36.211 really states "In case a single cell-specific reference signal is configured, cell-specific reference signals shall be assumed to be present on antenna ports 0 and 1 for the purpose of mapping a symbol-quadruplet to a resource-element group, otherwise the number of cell-specific reference signals shall be assumed equal to the actual number of antenna ports used for cell-specific reference signals. The UE shall not make any assumptions about resource elements assumed to be reserved for reference signals but not used for transmission of a reference signal". Even though it is still not quite clear why the standard requires so, but at least it is the fact that it does. Thank you anyway.

11 12 2017
05:09

Andrew Kolomatski

Hi Niviuk! Thanks a lot for everything in this resource and especially for your iconic radio resource grid generator. However may I ask you for one clarification please on the CRS mapping to resource elements. When I select a single antenna case (Tx antenna port/number of ports: 0/0), I can see that in PBCH (light blue) region the resource elements reserved for ALL FOUR reference signals are excluded. This is absolutely in line with 36.211 "The mapping operation shall assume cell specific reference signals for antenna ports 0-3 being present irrespective of the actual configuration. The UE shall assume that the resource elements assumed to be reserved for reference signals in the mapping operation above but not used for transmission of reference signal are not available for PDSCH transmission. The UE shall not make any other assumptions about these resource elements." But at the same time I can see that under a single antenna case in your PDCCH region the resource elements in symbol 0 of every slot 0 reserved for reference signals of TWO antennas are excluded. Can you please clarify why despite only one antenna port there are two RE's reserved for CRS in symbol 0 of every slot 0 instead of one?

5G TF calculator issue is fixed. 5G TF UL/DL ratio is not 3GPP, it is only a predefined static choice to display alternate UL and DL subframes. I can try to propose a digital value for UL and DL to avoid predefined choices

21 11 2017
15:16

Alfonso

Great work Niviuk! The web is very useful. One question: in http://niviuk.free.fr/fiveg_sfn.php in the 5G TF Frame parameters there's one UL/DL data cycle. Where in the specs can I find this parameter?

20 11 2017

5G channel to frequency calculator is not working. Can you please help to fix it?

This is a very useful tool, thank you, Niviuk, for making it! Not sure if it only happens to me or my friend, seems recently the webpage(s)/tables doesn't show up correctly. We tried Chrome/Firefox or even MS IE, but same issue. Any ideas?

22 10 2017

Niviuk

Hi, for all techno, there is now an option to search for a frequency range. The filter/sort option is now saved after selection. LTE geographical area option is selected by default. I disabled the UMTS equivalent band by default, but I can enable it back easily. Cheers

11 10 2017
21:45

paulhw

Thanks for such a useful resource. I use the LTE bands page once or twice a week! A few suggestions: 1) I find that every time I go to the LTE bands page, I change the sort order (it's not actually a 'Filter') to "DL Increasing" and turn on the Geography checkbox. Any chance those can be made the default?, 2) After changing and pressing Display, the Filter popup and checkboxes change back to their default; it would be nice if they stayed at the selected value to indicate what the table is showing (that confused me a couple of times), 3) It doesn't seem you can turn off the channel numbers anymore; the EARFCN check box appears to be ignored. I swear this used to work.

Hi Anant, I added on the UE capabilities a filter by band, number of carriers, or uplink CA

10 09 2017
21:54

Niviuk

Hi Jesse, I added in the "Export" menu a search for a single frequency, a frequency range, in uplink or downlink, for all technos. The menu name is not intuitive but I did not find where else to add it

20 08 2017
12:20

Jesse

Could you add a search function for LTE bands where you enter a frequency or a frequency range and it would show all bands that include that frequency/range? Would be really useful!

18 07 2017

Sunil Joseph

I believe measurement gaps ought to be 6ms long everytime. When selecting gapoffsets can they be spread over two SFNs ?. If my understanding is correct, then the display does not show the entire 6 sub frames in such cases

Hello ,excellent work ! I wonder if the bands 5150-5250 and 5725-5850 are for LTE downlink or Uplink, because in the LTE field i found the specification of DL only and in the WIFI field is marked LTE UL !! Thank u in advance :)

Stefan Blomeier

Dear Sir, regarding LTE TDD you made nice table and picture for the SSF. But I think there is a mistake in the description for "SSF Special SubFrame, normal CP (Dw / GP / Up)" => you named the column "number of slots per subframe" but it should be rather "number of OFDM-Symbols per subframe" as the Normal CP allows for 14 Symbols in a Subframe of 1ms. thanks for your great tables and analysis. I appreciate your efforts. kind regards, Stefan

RS, I changed the Earfcn values for B70 to fit with the frequency band range, waiting for the next 3GPP release. Wazzup, the RRC message UE Capability Information provides all the CA combinations supported by the device

31 08 2016
14:59

RS

Great site, use it regularly for my work. LTE Band 70 seems to be incorrect, UL should be 1695-1710MHz and DL 1995-220MHz. However EARFCNs in the spec also seem to be wrong.

Wazzup?

Wonderful site! One question though, is there a way to know the CA bands (and bandwidths) that are supported by a LTE phone/chipset? It might be traced via capability messages but before enabling CA on some bands, we would like to be able to know if it will be used or not (even though it is specified in 3GPP CA band combinations).
