SgNB Add Fail Radio due to UeCapability

Cesar_Nunes · September 21, 2021, 3:00am

Hi Experts.

gNB is sending the SGNB_ADD_REJ to eNB with “Target-not-allowed” and increasing the N.NsaDc.SgNB.Add.Fail.Radio.UeCapability.

Any suggestion?

It is somethign related to ue CAPABILITY.
Maybe your UE does not support 16 or 32 CSI-RS ports or something similar.
Number of SgNB addition failures caused by UE capability issues in LTE-NR NSA DC scenarios.
Compare sgNG_ADD_REQ for a working case with your case and you will find the issue.

The problem is I don´t know who is the UE.

Could be just a faulty UE.

Most probably there is no NRSCGFREQCONFIG configured on the LTE side for this band combination.
