Massive MIMO solution can use 8, 16, 32 and 64 antennas?
16, 32, 64
mMIMO means > 8
8T8R support MU-MIMO in LTE.
For mMIMO number of AE to be greater then 8.
Yes, but for MU-MIMO minimum requirement is 8T8R.
Both are different technology.
You can say MU-MIMO subset of mMIMO (8,16 layers).
With 8T8R I believe we have single beam and 2 users can multiplex only.
4 users with 8T8R?
I don’t think it is possible…
4 layer beam forming, as per Huawei specification.
Let me check. Is it tm7 mode?
Single stream beamforming, then possible…
With dual stream beamforming tm8 not possible.
I am talking about MU-MIMO.
MU-MIMO required some TM mode without which it can’t work.
Hope so we are on same page discussion ongoing for MU-MIMO with LTE.
Yes. With TM8 you can serve 4 UEs simltaneously with RI=1.
TM8 (dual layer beamforming)-based MU-MIMO for two users and each user with only one layer.
Two users are paired and then share the same PRBs, each user one codeword.
Uses TM8 antenna ports 7 and 8.
This is with TM8 using 8T8R.
Not sure how Huawei used 4 layers with 8T8R TM8.
4 layer in TM9.
Tm9 can go upto 2, 4, 8 port using csi-rs.
User beam used 7 to 14.
