USER EQUIPMENT APPARATUS FOR TRANSMITTING A PLURALITY OF SIGNALS SIMULTANEOUSLY USING AT LEAST TWO WIRELESS COMMUNICATION SCHEMES AND METHOD THEREOF

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.
