Proposal

 

 

During offline discussion
after the parallel session on Agenda Items 12.3 and 12.4, the very late session
attendees arrived at the following text proposal for inclusion into TR 36.814.

Annex B1: M.I.M.O. (Informative)

B1.1      Scope

 

The
following section describes the M.I.M.O. approach and is best understood in
conjunction with the tune of the song “Y.M.C.A.” performed by Village People
played in the background.

B1.2      Lyrics

 

U-E,
when your channel looks fine,

I
said, U-E, give the network a sign,

Which
means, U-E, give a high C-Q-I,

To
report what you have measured.

 

U-E,
there is data for you,

And
two codewords,

I
think they may come through,

So
let’s put them onto different ports

And
use spatial multiplexing.

 

In other words it is M-I-M-O.

In other words it is M-I-M-O.

You don’t need M-L-D,

There are plenty of ways,

Manufacturers have a choice …

 

M-I-M-O.

In other words it is M-I-M-O.

Two antennas you need,

Four by four is agreed,

And your throughput can be so high!

 

U-E,
can you see the Node-B?

Come
on, U-E, should it do T-x-D?

Alamouti
is a simple approach.

But
you’ve got to know this one thing!

 

Node-B
is not serving just you.

I
said, Node-B, has a whole cell to do,

And
at cell-edge there’s no M-I-M-O

‘Cause
the S-I-N-R is low.

 

You cannot always do M-I-M-O.

You cannot always do M-I-M-O.

Two R-x ports you have

So you still can combine,

And the coverage should be fine …

 

M-I-M-O.

It’s good for you to use M-I-M-O.

Two antennas you need,

Four by four is agreed,

And your throughput can be so high!

 

U-E,
if you want to transmit,

I
say, U-E, MI-MO
isn’t legit,

You
will have to wait for L-T-E- A,

Where
RAN-1 will make it okay.

 

That’s
where the decisions are made,

And
where many MI-MO sessions run late,

So
that Dirk says: ‘Juho will you take care

Of
this bunch of loopy people?’.

 

It’s fun to standardize M-I-M-O.

It’s fun to specify M-I-M-O.

You don’t need M-L-D

There are plenty of ways,

Manufacturers have a choice …

 

M-I-M-O.

It’s fun to specify M-I-M-O.

When your channel looks fine,

Give the network a sign.

 

M-I-M-O.

Then just go and do M-I-M-O.

Can you see the Node-B?

Should it do T-x-D?

 

M-I-M-O.
