Is it possible in NR to have 2 codewords with FR1 when no of layers > 4?

Hi Experts.

Is it possible in NR to have 2 codewords with FR1 when no of layers > 4?

Any network having such deployment?

Does it require 6 RX at UE end?

It is possible to have 2 codewords when layers > 4 but no vendor and UE implemented yet 8 x 8 MIMO in DL in 5G.

Just for LTE Huawei has such a CPE with 8x8 DL MIMO:

Thank You!

But I would say that 8 x 8 DL MIMO is useless.

In drivetest we see 4 layers MIMO in less 10% of samples. Same from counters.

I guess 8 x 8 MIMO will be less than 0.5% of samples.

It is useless investment to develop it just for 0.5% of samples…
