The present technology relates to a wireless communication apparatus and method by which communication can be performed with a higher efficiency.

The wireless communication apparatus includes a preamble generation section that generates a preamble that is to be deployed at the top of a transmission frame and includes header information, a midamble generation section that generates a midamble that is to be deployed in the middle of the transmission frame and includes information of at least part of the header information, and a wireless transmission processing section that transmits the transmission frame including the preamble and the midamble. The present technology can be applied to a wireless communication apparatus.

A wireless device transmits a first signal in a first cell group and transmits a second signal in a second cell group. The wireless device adjusts a signal transmission power of one of the first signal and the second signal if a power value exceeds an allowable transmission power and if an overlapping in time exceeds a first duration.

A method implemented on a mobile device that starts by receiving a temperature reading from a sensor included on the mobile device. The temperature reading is compared to a threshold temperature and a power cap is set when the temperature reading is greater than the threshold temperature. The power cap is a maximum transmission power of the mobile device. The method then determines if the mobile device is transmitting a critical message. The power cap is released for a period of time if the power cap is set and the mobile device is determined to be sending a critical message. Other embodiments are also described.
