Cell identifier and CE level for CE capable UEs

Dear Experts

While post TAU Reject I am getting this IE:
Cell identifier and CE level for CE capable UEs

While in case of TAU Accept and TAU Complete in UE Context release complete getting IE
User Location Information.

But not getting this IE.
Cell identifier and CE level for CE capable UEs.

I Know its a normal flow as per available traces of 2 diff vendors , bjt not getting any evidence from 3GPP docs.

Pl can anyone suggest anything.
