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 (UE) including first and second antennas; a first wireless communication chip configured to output first and second signals corresponding to first and second frequency bands, respectively; a second wireless communication chip configured to output thirds signals corresponding to a third frequency band; and a radio frequency (RF) front-end module configured to transmit the first and second signals corresponding to the first and second frequency bands output from the first wireless communication chip to the first antenna, transmit the third signal corresponding to the third frequency band output from the second wireless communication chip to the first antenna, transmit the second signal corresponding to the second frequency band externally received in the first antenna to the first wireless communication chip through a secondary Rx path, transmit the second signal corresponding to the second frequency band externally received in the second antenna to the first wireless communication chip through a primary Rx path, and transmit the third signal corresponding to the third frequency band received in the first and second antennas to the second wireless communication chip.

User equipment for simultaneously transmitting signals to which different wireless communication systems are applied through a plurality of frequency bands

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
