1. A method of controlling a transmission power by a user equipment in a wireless communication system supporting a plurality of serving cells, the method comprising:
when a physical random access channel (PRACH) transmission in a first timing advance group (TAG) in parallel with a physical uplink control channel (PUCCH) transmission in a second TAG are requested,
if a total transmission power of the PRACH transmission and the PUCCH transmission exceeds a maximum transmission power configured for the user equipment in a time period, preferentially allocating a transmission power for the PRACH transmission with a priority higher than an allocation of a transmission power for the PUCCH transmission; and
transmitting the PRACH based on an allocated transmission power for the PRACH transmission.
