1) If possible, I would like to see one more parameter - the use of the operatorMIMO and its mode.
From the topic about NSG, I stole such a description of the main parameters of the channel - it can be useful (if not in the topic - it can be deleted).

So - about MIMO - there would be interesting almost no information about the MIMO mode (the description of my own modes - if I lied - do not hit hard).
TM1- without MIMO
TM2- duplication mode - in order to increase the reliability of the transfer of information
TM3- mode of increasing the speed of data flow due to unparalleling
TM4- parallel transmission mode with the ability of the receiving device to interfere in this process.

This info about the use of MIMO operators is especially interesting for modems who are going to build (buy) antennas - to understand the need for MIMO antenna options.
Separate interest is the use ofMIMO to 3G(there are many conversations and statements about this - but all are unfounded), unless of course NSG provides such info in 3G.

2) I found a picture with ranges and their use by operators in the Moscow region (or in Moscow itself - I won’t say for sure), as of 2014

In my opinion - very clearly, but perhaps requires clarification.

3) And yet - there was a message about the use of adjacent sections of the bands,
whatMTS and Beeline entered into an agreement, and make tests to combine their adjacent lanesat 10 MHz in the range of 2600.
The first test takes place in Cherepovets from November 2016. The trend, from my bell tower, is interesting, but how it looks in reality is not known ...

So - about MIMO - there would be interesting almost no information about the MIMO mode (the description of my own modes - if I lied - do not hit hard).

If you will allow, I will add another such picture:

Also, a certain interestpresents an articleon LTE Transmission Modes and Beamforming on Rohde & Schwarz (link is in the NSG topic).

And a small addition to the description of Transmission Modes:

http://wiki-org.ru/wiki/MIMO

MIMO systems can be classified by the presence or absence of feedback:
a) MIMO with "open loop" (open-loop). In this case, the channel estimates at the receiving end are used to correct for the distortions introduced by the channel;
b) MIMO with "closed loop" (closed-loop). Here, in addition to channel estimation at the reception and compensation of interference, these estimates are transmitted to the transmitting side via the so-called feedback channel. Based on the received information, the transmitter redistributes the power in its transmitting paths in order to increase the power of the paths transmitting through the channels with high fading intensity, and also to make corrections in amplitude and phase during the formation of the antenna pattern.
In turn, open-loop and closed-loop are divided into transmit diversity and spatial multiplexing.
In the case of a closed-loop, based on measurements of the cell reference signals, the terminal selects the appropriate transmission order and precoding matrix. Information on the selected order and precoding matrix (precoding matrix, PM) is sent to the network in the form of a rank indication (RI) and a precoding matrix (PMI). However, it is important to understand that RI and PMI are optional, networks do not need to follow RI / PMI sent by the terminal. If the network selects other RI / PMIs other than those sent by the terminal, then the network should inform the terminal which PM was used in the downlink transmission. If the network used the PMI recommended by the terminal, the network only sends a confirmation signal to the PMI.
In order to restrict the transmission of signals from both the ascending and descending lines, only a limited set of PMs, also referred to as 27 codebooks, are defined for each transmission order for a given antenna port number. Both the terminal (when it selects PMI) and the network (when it responds to the terminal about the choice of matrix) must select a precoding matrix from the appropriate codebook (“code book”). Thus, when the network sends information about the selected PM to the terminal, only the index of the selected matrix is ​​transmitted.

[andrew.woronkov]

sandwern,
Thank! Very useful technical info.
Looking at the picture - I saw on it thin dotted lines with arrows (possible directions of transition from mode to mode?).
I didn’t see a switch there from TM1 to TM2, from TM2 to TM3 and TM4 (or do these arrows mean something else?)

And more ... It would be interesting to understand how the transmitting side assigns these modes for the terminal?
For pairs TM2 and TM3, TM6 and TM4 - this is sort of like link quality (there is a low SINR condition in small type, hi SINR condition is written - and what value is taken as a threshold?)

[sandwern]

[email protected], 10:54

And more ... It would be interesting to understand how the transmitting side assigns these modes for the terminal?

Just in case, I attach the file where the picture was taken from (the author is banned from SlideShare, I had to look for other resources). This document, in my opinion, is generally a storehouse of information, except perhaps it would be in Russian :)

In fact, only a specialist can answer your question, I can only suspect. Once, looking at the QXDM logs when working with one mobile router, it was possible to notice a message that contained information about the LTE UE category and the number of antennas for reception and transmission:

Selected Duration: 00: 00: 00.000 (0.00 sec)
2016 Aug 28 18: 51: 27.619 [00] 0x1FEB Extended Debug Message
lte_misc.c 332 H RRC CAP: UE cat = 11
Drop count = 0

2016 Aug 28 18: 51: 27.619 [00] 0x1FEB Extended Debug Message
lte_ml1_dlm_rx_cfg.c 7306 L UE Capability Req sent: num_rx_ant = 2, num_tx_ant = 1, ue_category = 11, max_cc_dl = 2, max_cc_ul = 1
Drop count = 0

So I understand that the user device (UE) sends this data to the base station, and it already decides what type of transmission will be used based on the maximum number of MIMO streams supported by the device and signal quality, as well as the amount of traffic transmitted per unit time based on monitoring using Network Signal Guru). Again, this is only a guess, the situation may differ from the real state of things ...

The document on page 7 has an approximate explanation of how this works. Only I will not be able to translate it without losing the meaning word-for-word, therefore, I probably will not give a quote here, if possible.

[email protected], 10:54

Looking at the picture - I saw on it thin dotted lines with arrows (possible directions of transition from mode to mode?).

Also so eager to suggest. And here's why - on page 9 of the document it is said that the closed loop transmission schemes are usually used when the subscriber (user) is not mobile, i.e. This stationary terminal or pedestrian. In the case when the subscriber is moving at high speed, for example, on a car, the MIMO mode can be used with an open loop, since information on the status of the channel cannot in this case be relevant and timely at a certain point in time. Therefore, we conclude that it is possible to change the transmission mode when certain conditions change on the part of the subscriber.

Just in case, the full text (in English):

Multiple Input Multiple Output Multiple Output (MIMO) Standardized Multiple Output Multiple Output (MIMO) Beyond Modes as well as transmit diversity and Multi-User MIMO (MU-MIMO). In the closed loop MIMO mode, the Channel Indications (RI) and the Precoder Matrix Indications (PMI) provide channel feedback to the eNodeB with Channel Quality Information. This is the most commonly used scheme in current deployments. However, this scheme provides a multi-path environment. Thus, closed loop MIMO is not appropriate in low mobility environments such as pedestrian speeds.

It is not a time when the MIMO can be used. In the TDD network, it has been possible to follow it up. Thus, MIMO improves TDD networks under wider channel conditions than in FDD networks.

sandwern,
Yeah, I’d have to smear my rusty knowledge in technical English and try to understand the document.
I will hide all my further thoughts under the spoiler, otherwise the moderator will blink: blush:

From the purely user side, I made a conclusion for myself:
- if the transmitting side supports the MIMO mode,
- if the terminal is also able to work in this mode
- if they agree among themselves about using this mode
then there are 2 possible options:
- we stand still or move at a pedestrian speed and the SINR is large enough and we request a lot of traffic on the client,
that is, there is a certain probability of receiving the TM4 or TM3 mode with two channels (in the most common 2x2 variant now) for reception and, accordingly, we can count on an increase in reception speed;
- if we move on cars - then we can expect to get TM2 (which, in general, is also not bad).
(obtaining a variant of TM3 in this case is not very likely - for this, the SINR should be large enough and stable, perhaps I’m just fantasizing, but in fact it’s different)

sandwern,
He felt like a student who is taking the exam tomorrow.
Recruit literature, and at night to master everything, and write spurs)))

Or maybe there is a similar technical literature about the 3G mode DC-HSPA +?
According to unconfirmed data, DC means double carrier (is it necessary to understand that two frequency slots can be given to one client?) And plus sign = MIMO.
Althoughherethere is no such designation at all - there is HSDPA, HSPA +, Dual-Carrier HSDPA, DC-HSDPA w / MIMO
Quite 3gpp was confused with its releases and protocols ...

And there is also DB-DC-HSPA - in different ranges, Dual-Band - Dual-Cell. They say that the latest version of HSPA, but it seems that there is no such thing in Russia ... Something similar was mentioned about Tele2 by someone on the forum, but I don’t know for sure, maybe I’m confusing.

DB-DC-HSPA

About DB did not hear. But I heard about MC-HSPA +. those. Multi Carrier. Aggregation of up to 4 carriers from different bands (i.e. up to 20 MHz, an aggregated channel can be obtained). But I still have not seen a single commercial terminal that would support it. And about the MC-HSPA + network in the world something is not audible. Do they exist at all? I doubt it.

[andrew.woronkov]

In general, these protocols for 3G have great potential - modulation to qam64, and the possibility of combining channels, and MIMO, and transmission speeds are good for everyday needs ...
But he didn’t have time to choose his options, how LTE came and “buried” him - LTE will soon take up all bands, and GSM and 3G (((
And how then will marketers and operators lure customers and customers? Although it is possible to wind dials in the title - 5G, 6G, 7-8-9 ...
Yes! And speed! 1.5Gbps per second, 10Gbps))) By then, media content producers will come up with SuperPuperHiDef holographic movies)))
So it won't be boring ...

how MIMO modes depend on SINR and speed

In my opinion, you are too deep into the theory. For the purposes of discussion in this topic, in my opinion, it is enough to notice and note if MIMO with 4 independent streams is supported in a particular network. I just call it MIMOx4 - unlike MIMOx2 with 2 streams, which are supported by default with any Cat.3 device or higher, as well as with any LTE network infrastructure equipment currently in use.
The value of supporting MIMOx4 in a network for mobile devices, as I have already said, is small - due to physical limitations when placing antennas in the case.
And such support itself is displayed in the NSG interface (on the appropriate equipment, of course), as shown inthis video from new york.

[andrew.woronkov]

In my opinion, you are too deep into the theory.

I agree, just "Ostap suffered." If you tell me where this discussion of the technical aspects of cellular communication would be more appropriate - I can only say thank you.
But our conversation about MIMO began exactly with my wishindicate whether MIMO was seendifferent operators in different ranges
andwhat modes TM2 TM3 TM4 TM5 were seen. Although I think that this information will be very different for different BSs of the same region.
But it would still be interesting, especially since this NSG info shows, so why not add it to the reports and to the cap?

sandwern,
Once again, I will thank for our conversation and information on the technical aspects of LTE - I for myself (I think that the info was useful not only for me) unraveled some things, destroyed some of the “urban legends”)))
From the latter - again from that pdf I took out the info, which is not necessarily the use of X-polarized antenna emitters with MIMO -
This may well be the series of emitters with vertical polarization.
