1. A method performed by a terminal in a wireless communication system, the method comprising:
identifying that a first physical random access channel (PRACH) transmission of a master cell group (MCG) is overlapped with a second PRACH transmission of a secondary cell group (SCG) in a time domain and a sum of a transmission power determined for the first PRACH transmission of the MCG and a transmission power determined for the second PRACH transmission of the SCG exceeds a configured maximum transmission power for the terminal;
performing the first PRACH transmission of the MCG based on the transmission power determined for the first PRACH transmission of the MCG according to the identification;
according to the identification, reducing the transmission power determined for the second PRACH transmission of the SCG and performing the second PRACH transmission of the SCG based on the reduced transmission power of the SCG; and
in case that no random access response associated with the second PRACH transmission of the SCG is received for a predetermined time, determining a transmission power for a third PRACH transmission of the SCG based on skipping an increase of a counter associated with the transmission power for the third PRACH transmission of the SCG and performing the third PRACH transmission of the SCG based on the transmission power determined for the third PRACH transmission of the SCG.
