Hello Experts.

I know how to check if a UE supports 5G DSS.
But how to check if the network configured the operation mode to be DSS or not from the UE log?
I do not have access to network traces or configuration, just the UE log is that I have. And I try to understand if log is with or without DSS.
Band 28 is for NR.

Try checking RRC Connection Reconfiguration messages and search for: lte-crs-Tomatcharound which will configure rate matching pattern around LTR CRS.

Also try searching for mbsfn-subframeVonfigList which will indicate mbsfn subframes configuration.

Is this to be checked in the RRC reconfig that setup the NR?

Or in any other RRC reconfig before setting up NR?

RRC reconfig correlated with NR setup.

Thanks a lot.

I found it: lte-crs-Tomatcharound:setup and with few params to configure it.

So it is DSS.

There is white paper about DSS, from Mediatek, check it here: Dynamic Spectrum Sharing (DSS) - MediaTek - Mar 2020
