Certain aspects of the present disclosure provide a technique for a user equipment (UE) to signal UE assistance information (UAI) to setup or release a cell group (CG). For example, the technique may be executed to generate the UAI, which may indicate whether the CG such as a secondary cell group (SCG) should be setup or released for the UE when operating in a multiple radio dual connectivity (MR-DC) mode. The UE assistance information may be transmitted to a base station (BS).
