Abstract
The present disclosure relates to a communication apparatus, a communication method, and a program that enable improvement in performance of short-range wireless communication. The communication apparatus includes: a reception circuit that receives a signal transmitted by load-modulating in a card, which is a partner in short-range wireless communication, via an antenna; and a transmission power control unit that controls transmission power transmitted to the card on the basis of a reception signal modulation degree which is a modulation degree of the signal received by the reception circuit. Then, the transmission power control unit performs control so as to reduce the transmission power in a case where the reception signal modulation degree is less than or equal to a certain threshold value. The present technology can be applied to, for example, a communication apparatus that performs short-range wireless communication.
