1. A method performed by user equipment, comprising:
upon receiving a radio resource control (RRC) reconfiguration message which includes an indication to indicate secondary cell group (SCG) deactivation,
stopping radio link monitoring on a primary SCG cell (PSCell) of the SCG,
deactivating all secondary cells (SCells) of the SCG,
determining whether a signaling radio bearer 3 (SRB3) is configured and the SCG is deactivated,
if the SRB3 is configured, and the SCG is not deactivated,
submit a measurement report message via the SRB3 to a lower layer for transmission, and
if the SRB3 is configured, and the SCG is deactivated,
submit the measurement report message via a signaling radio bearer 1 (SRB1).
