Should these indicate power class 2 in the field ue-PowerClass of the UE-NR-Capability, the MOP capability in fall-back is ambigous (23 or 26 dBm).\nThe unwanted emissions requirements are measured at each antenna connector and not as the total of emissions from all antenna connectors as required by regulations in several regions\/countries.","secretary_remarks":"","agenda_item_sort_order":14,"ainumber":"4.4.2.1","ainame":"Power class related to UL MIMO and other related req.
