The present technology relates to a wireless communication apparatus and a wireless communication method that make it possible to read necessary information even in a case where a physical header at a top portion of a signal transmitted from a base station of another BSS fails to be received and the signal is received from the middle. The wireless communication apparatus includes a communication section configured to generate and transmit an OFDM signal in which second information is superimposed in a frequency axis direction of the OFDM signal which includes first information destined for one or more subordinate client devices. The present technology can be applied to a wireless communication apparatus and so forth that perform wireless communication, for example, standardized by IEEE 802.11.

Wireless communications are described. A wireless device may be configured to transmit a first signal via a first cell group that may overlap in time with a second signal via a second cell group. The wireless device may adjust a signal transmission power of at least one of the first signal or the second signal. Additionally or alternatively, the wireless device may drop at least one of the first signal or the second signal. Adjusting and/or dropping at least one of the first signal or the second signal may be based on the overlap in time of these signals satisfying a duration threshold and a total power to transmit the first signal and the second signal exceeding a power threshold.
