Abstract
Provided are a method and a terminal device for setting uplink transmission power in a wireless communication system. A terminal acquires information on the time alignment group (TAG) for multiple supportable serving cells so as to constitute TAGs, checks whether an overlap section of subframe n and subframe n+1 for uplink transmission exists between TAGs, and sets uplink transmission power so as to scale the uplink transmission power (PCMAX) within the range that does not exceed the configured maximum transmission power (PCMAX) of the terminal in the checked overlap section. Here, the uplink transmission power considers the maximum transmission power for multiple serving cells contained in the TAGs.
