OAI 5G CSI-RS Periodicity Issue

Hi OAI developer,

I am using OAI gNB and OAI nrUE to conduct a CSI-RS-related research. I am using 2023.w37 nrUE. For gNB, I have test 2023.w16 and 2023.w37 with the same gNB config (MIMO and CSI-RS enabled).

I find that the nrUE measure and report CSI-RS every 8 frames in 2023.w16 gNB. However, in 2023.w37 gNB, the nrUE measures CSI-RS every 16 frames while reporting CSI-RS every 8 frames. I checked the code and found the above difference is resulting from the change

const int ideal_period = nb_slots_per_period * MAX_MOBILES_PER_GNB;   --->   const int ideal_period = 320;

in commit _ 93d6ae6d_ .

Is this a feature or a bug?

Thanks, Hai
