1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving information on dynamic power sharing (DPS) for dual connectivity;
identifying sub-carrier spacing (SCS) configuration information and information for a physical uplink shared channel (PUSCH) processing capability;
determining a time offset Toffset based on the SCS configuration information and the information for the PUSCH processing capability;
determining a maximum power for a PUSCH transmission on a secondary cell group (SCG), based on the time offset Toffset and a transmission on a master cell group (MCG) that is scheduled by a downlink control information (DCI) format; and
performing the transmission on the MCG and the PUSCH transmission on the SCG, wherein a power for the PUSCH transmission on the SCG is determined based on the maximum power.
