Transmitting apparatus and wireless communication method

A transmitting apparatus having a retransmission function of data in response to a retransmission request from a receiving apparatus in accordance with one of a plurality of classes of modulation and coding scheme which is determined based on a request from the receiving apparatus, the transmitting apparatus comprising:

• a storage portion which stores information indicating a transition of an error rate in communication with respect to a communication quality for each of the classes of modulation and coding scheme in a case in which the retransmission function is enabled and in a case in which the retransmission function is disabled;
• a function switching portion which switches whether to enable or disable the retransmission function in accordance with a type of data to be transmitted;
• and
• a scheme determining portion which determines a class of the modulation and coding scheme based on whether the retransmission function is enabled or disabled while referring to the information,
• wherein, when a class of modulation and coding scheme in the case in which the retransmission function is enabled is switched into a class of modulation and coding scheme in the case in which the retransmission function is disabled, the function switching portion switches the class of modulation and coding scheme so that, with respect to a communication quality derived from the class of modulation and coding scheme and the error rate before switching, the error rate after switching becomes equal to or lower than the error rate before switching.
