How to find the location angle of the UE w.r.t the RIS when working with srsRAN 5G?

[AvishekDeb]

Hi All,

We are working on integrating our RIS with srsRAN powered 5G connectivity. One of the issues we are facing currently is regarding the determination of the precise angle of the UE w.r.t the RIS using the srsRAN stack so that we can steer the beam towards the UE. We are working in FR1 band with a central frequency of 3.5GHz. Request your assistance or response to this. All ideas are welcome.

Thanks & Regards.
