Is MIMO supported in srsUE zmq mode

[Zplusless]

Hi, I cannot find any discussion on MIMO in ZMQ.

Since srsUE zmq mode supports a maximum bandwidth of 20 MHz, is it possible to acquire a higher brate using MIMO in zmq mode?

I have found some conflicting information, and it makes me confused.

1. srsUE support MIMO: Advanced Usage — srsRAN 4G 23.11 documentation

2. srsUE does not support MIMO: New release: MIMO 4x4 and improved performance #109 (reply in thread)

Hi, the srsUE contains both 4g and 5g versions, but MIMO is supported only in 4g version.

What a pity. Thanks for your help!

So the problem is in srsue itself not the ZMQ?
if I use just srsran gNB with ZMQ to send IQ samples over ethernet to another machine I can use MIMO right?

Hi @anasalbakri, do you find any alternative to SRSUE?

Hi @anasalbakri, do you find any alternative to SRSUE?

Hi @Zplusless
Well, for now I'm limited to it but I might try with COTS UE.
As for throughput did you get any better than 76 Mbps? for SISO, Bandwidth 20 MHZ, SCS 15 KHZ.
I got maximum 76 Mbps with ZMQ and only 15 Mbps with USRP B210. I'm wondering if that's their limits.
