Hi Experts.

How many maximum PDSCH beams are possible in one TTI (0.5 ms) for SRS based beamforming for FR1?

2

Which vendor?

Huawei has 16 pdsch layers for MU-Mimo in dl regardless if PMI or SRS.

Also 4 PDCCH layers for mumimo.

And in UL has 8 PUSCH layers for mumimo.

Only criteria is that UEs to be paired properly.

3

What about the SU MIMO?

Not vendor specific.

I mean any limitation in the no of PDSCH beam.

Also any relation with the SS block.

4

I think maximum 4 layers for sumimo.

5

Suppose there are 10 UEs and 8 UEs are using RI=1 and 2 are using RI=2 ( no mu mimo).

So how many total no of PDSCH beams will be required in that particular TTI?

Is it 10 beams?
