Hi, I do not work anymore with UE vendors; sorry but I don't maintain this parser since a long time |

Will this UE Cap Parser tool start to work again for use with Qaulcomm and Mediatek soon?
I think it doesnt work possibly due to all the characters from the ueCapabilityRAT-Container portion in the UE Cap message? IT hasnt worked for us in some time and so many of us rely on this tool daily. Qaulcomm has their own internal tool now to parse but we do not and would love for it to work again please. |

Hi Eric Shen, there was only a check on the downlink arfcn, I added a check on the ul arfcn, both DL and UL are checked now, but please read next post ... |
25 03 2020 |
Eric Shen |
Dear Niviuk, just noticed something interesting, when I used the EARFCN calculator in LTE Freq. Band section, if I put ARFCN as 67062 (of Band 66) and BW as either 15MHz or 20MHz, the check results still show OK while in realty the UL portion is already out of Band 66... Any chance to double check? Appreciate your help!
Here are more details:
ARFCN 67062 -> DL 2172.60MHz UL 1772.60MHz -> If 15MHz, the upper UL 1780.1MHz; if 20MHz, the upper UL 1782.60MHz (but upper band edge of B66 UL is 1780MHz) |

Hi, for 5GNR FR2, 1CC max data rate is 808 Mbps (2x2, MCS28). In this case, for purposes of BLER calculation, what is the bit size of the "block" used to calculate BLER? Also, is this equation a reasonable assumption for converting BER to BLER? BLER ~ [1 - (1-BER)*(Block Length in Bits)] Thanks! |

Thiago Marcengo |
Hello, Mr. Niviuk.
On the http://niviuk.free.fr/nr_frame.php the Slots with SSB may or may not have PDSCH allocation simultaneously. Nokia currently doesnt schedule PDSCH with SSBs, but other vendors do. Maybe you could place a note saying something like that.
Thanks for your awesome work, I`m a heavy user of your site! Cheers! |

Hi,

In LTE + NR Dual Connectivity (http://niviuk.free.fr/nr_dc.php) I didn´t find in 3GPP TS 38.101-3 V15.7.0 (2019-09) the "DC_1A_n3A-n78" (Inter-band EN-DC within FR1 (three bands)
Is it correct in niviuk web page? |

Dear sirs, 2 questions on 5G NR please :
1. In the "UE radio access capability 38.306" rate formula, I don't see the influence of TDD (for instance 50% of Downlink rate compared to FDD)
2. what is the scaling factor, it is not defined, do you know ?
Thanks a lot |

Hi Niviuk, sent a message yesterday about UE Capability decoder file format. I just found a file that works, it is the native format of the RRC message as captured with e/// celltrace. So I am all fine :) I can send you the file if you want to use it as a template file. |
28 01 2020 |

Hi mgolden, I agree, I will check the code |

Hi Andy, Band names comes from the web, or names I often heard, or personal naming. For n79, I can change to TDD 4700. Updated LTE S1 and X2 asn1. |
28 01 2020 |
Xavier |
Hello Niviuk, In the UE Capabilities pretty viewer, could you please include a template file, so we can undertand the kind of input supported ? The message is 3GPP, so it could be coming from Qualcomm, Intel, Samsung, I'm pretty sure one could find a way to convert the raw file to the kind of file supported by your macro.
Thanks !! |

HI, seems FR1 refers to 410 MHz – 7125 MHz now. cf spec 38.101-3. BY the way i have one question, is anyone knows if LTE carrier of 1.4/3 MHz can be used as an anchor LTE carrier for EN-DC (Option 3x)?
ps: great site. :-) |
27 01 2020 |
Andy |
very helpful site, thanks! But how did you assign Band Names, especially for NR bands? Are they fixed in some document, or just a your suggestion? In 3GPP 38.104 spec there are no band names, only band numbers. For example, NR band n79 (4400-5000 MHZ) - should it be TDD 4500, as you wrote, or TDD 4700 according to the middle frequency ? |
23 01 2020 |
mgolden |
Your center channel for NR FR2 with 120kHz SCS is invalid. With step size of 2, center channel has to be an odd number. |

3GPP has changed the definition for the newradio nominal channel spacing ofr intraband contiguous CA carriers. The data on this website needs to be adjusted to reflect 3GPP 38.104 chapter 5.4.1.2 Channel spacing for CA (V16.1.0) |

Hi JK Park, band 66 is asymetric, DL bandwidth is 20 MHz larger than UL bandwidth; the middle frequency is computed as the middle of the DL band and the middle of the UL band |

Hi
About the frequency of LTE66/NR66 bands,

Hi.
The Point A calculation page is broken? For n1 for instance, it shows both 15 and 30 kHz SS/PBCH spacing, while only 15 is allowed? Furthermore, how come the ARFCN for Point A changes when the SCS for the PDCCH changes from e.g. 15 kHz to 30 kHz? Isn't Point A per definition a fixed point for all numerologies? |

Hi.
I am trying to understand 5G using this incredible site.
However, in the Point A calculation, I can't even understand how to get from the Arfcn range for a band to the allowed Arfcn range to Point A.
Would it be possible to clarify? Thank you! |

Hi Niviuk, o.k. thanks for that. I noticed my mistake: The RB value of 275 can be changed in the GUI but is actually a fix value, even if the channel bandwidth is only 90 or 80 MHz. If I leave it as it is I get the starting point and length value just fine :-) Thanks! |

For 5G NR, NR CSI-RS Multiplexing with PDCCH is a basic or advance feature? |
03 12 2019 |
Niviuk |
Hi Heurekus, for the RIV calculator, I use the value NR bandwidth part size in the light blue form for the parameter NsizeBWP in the RIV formula in 38.214. If you change the NR bandwidth part size value, it will be used to calculate RBStart and #RBs for the same RIV value |
03 12 2019 |
Alan Chu |
Point A definition does't seem correct. Per 38.211 - 4.4.4.2 Point A definition is as follows:
absoluteFrequencyPointA for all other cases where absoluteFrequencyPointA represents the frequency-location of point A expressed as in ARFCN, namely ARFCN should be the Point A. |
29 11 2019 |
Heurekus |
Hi, I've been playing around a bit with the RIV calculator as I wanted to get the first RB and the #RBs based on the BWP initialUplinkBWP IE.
In a network with 80 MHz (217 RBs) I get a locationAndBandwidth of 16499. I get to this value when I run through the original formula with 217 RBs channel bandwidth, starting RB = 0 and bandwidth of the BWP of 217 RBs. When I put 217 and 16499 in the calculator, I get RGBstart 7 and #RBG 77.
In a network with 90 MHz (245 RBs) I get a BWP locationAndBandwdith of 8799. Again that maps to RB start = 0 and bandwidth of 245 just fine. But if I use 245 and 8799 in the RIV calculator I again end up with different values: start 20 and #RGB 211.
Am I doing something wrong here? Sharetechnote has the calculations for 80 MHz on this page if you want to take a peek: http://www.sharetechnote.com/html/5G/5G_CarrrierBandwidthPart.html |

HI Team,
when we process UE cap in the webiste tool for ENDC combos supported below is the parsing given . If you see below parsing all first three line are same but actual difference is what is LTE PCC.
Can parsing be add like 2a - 12a - 30a - 66aa - n5 instead of 2a - 12a - 30a - 66a - n5,
2a - 12a - 30a - 66a - n5
2a - 12a - 30a - 66a - n5
2a - 12a - 30a - 66a - n5
2a - 30a - 66a - 66a - n5
2a - 30a - 66a - 66a - n5
2a - 30a - 66a - 66a - n5
2a - 2a - 30a - 66a - n5
2a - 2a - 30a - 66a - n5
2a - 2a - 30a - 66a - n5 |

Hi,
I am wondering if it's correct or questionable.
The NR radio resource allows the user to select PDCCH subcarrier spacing 60kHz in concert with SS/PBCH subcarrier spacing 15kHz and "successfully" produces the output grid. But at the same time the comment on the very same page lists the valid pairs of {SS/PBCH, PDCCH} subcarrier spacing as follows:
{15, 15},
{15, 30},
{30, 15},
{30, 30},
{120, 60},
{120, 120},
{240, 60},
{240, 120}}.
And there is no such valid pair as {15, 60}.
Am I missing something or is it really incorrect? |

Nice work :-)
I just noted that (at least) in New Radio Bands table you used abbreviations TD, FD, SU whereas in abreviations table their counterparts are TDD, FDD, SDL, SUL.
I suggest to use the s8sdtandard) three letter abbreviations in the table instead of the two letter abbreviation of the abbreviations ;-)

Hello. I'm an engineer in Korea. I have a a question about point A channel. I usually use a site of `NR Reference Point A`. when I fill information such as a frequency band, bandwidth, and ARFCN, I can got several ranges. here is the question. I'm just wondering how method to find langes of Point A, Allowed, Band. where can I find an evidence? I mean 3GPP or KDB like that. And then, sometimes I can see the message "not aligned with a step of 2", "is outside the allowed range". For example, when I was putting '622001' on the site, I thought that was in range. but the red error message was shown. Thanks for reading my question and I hope to reply an answer as soon as you can possible. have a nice day. |

For LTE band 53, you list the start/stop frequency as 2483.35 & 2494.85 MHz.

RBG in the NR RIV decoder ?? |
Could you help to clarify the definition of RBG in the NR RIV decoder ?
When the resource allocation type 0 used, the RBG stands for Resource Block Group;
When the resource allocation type 1 used, the RBG stands for Resource Block, 1 RBG = 1 RB ;

Maybe there is a bug in NR UE max data rate calculator. Acc. to 3GPP 38.101-1 n51 is only 5Mhz BW.
This would correspond to 25 RB @ SCS 15kHz. n78 is max 50MHz BW @SCS 15kHz with max. 270 RB.
Output is the same always 288.9 Mbps.
Other settings: 1, 1, 256QAM, 1, band, 15kHz, 0,14
Or is there some problem on my side?
