A user equipment (UE) of a wireless communication system is disclosed. A second receiving module, of a second wireless communication chip, is configured for receiving a transmission power value of a first signal configured to be transmitted from a first wireless communication chip of the UE. A second transmission power value determining module, of the second wireless communication chip, is configured for determining a transmission power value of a second signal configured to be transmitted from the second wireless communication chip, the determination based on the received transmission power value of the first signal and a predefined specific absorption rate (SAR) condition, wherein the first wireless communication chip is configured for transmitting the first signal using a first wireless communication scheme, wherein the second wireless communication chip is configured for transmitting the second signal using a second wireless communication scheme simultaneously with the transmission of the first signal by the first wireless communication chip.

User equipment apparatus for transmitting a plurality of signals simultaneously using at least two wireless communication schemes and method thereof

A user equipment apparatus for simultaneously transmitting signals from a plurality of wireless communication chips to which different wireless communication schemes are applied and a method for controlling a transmission power control of the user equipment apparatus are disclosed. The user equipment apparatus comprises a transmission mode decision module determining whether the user equipment apparatus is currently operated to transmit a signal through one wireless communication chip or simultaneously transmit signals, to which different wireless communication schemes are applied, through a plurality of wireless communication chips, and an intermodulation distortion (IMD) effect decision module determining whether a set of frequencies of the signals respectively transmitted from the plurality of wireless communication chips causes intermodulation distortion (IMD).

User equipment apparatus for simultaneously transmitting signals via a plurality of wireless communication chips to which different wireless communication schemes are applied and method for controlling transmission power thereof
