The present invention is to provide communication apparatus capable of selecting a transmission scheme suitable for a type of transmission information, its communication method, and programs. A transmitter/receiver portion 2 is capable of communicating under plural transmission schemes of different transmission rates in accordance with combinations of coding rates of a convolutional encoder and modulation schemes. A transmission scheme selection portion 5 prioritizes the transmission schemes in a plurality of different evaluation schemes in response to signal Ds representing the type of transmission information based on measurement results S4 measured at a measurement portion 4 and selects the optimum transmission scheme to be used for communications from the plural transmission schemes according to the prioritized result. The selected transmission scheme is sent to the transmitter/receiver portion 2 for switching the transmitter/receiver portion 2.
