1. A base station, comprising:
control circuitry, which, in operation, determines, based on operation of retransmission control being on or off, to activate or inactivate a frequency diversity transmission scheme configured to transmit information at different frequencies; and
communication circuitry, which, in operation, performs communication with a terminal with the frequency diversity transmission scheme in case the frequency diversity transmission scheme is determined to be activated, and performs communication with the terminal without the frequency diversity transmission scheme in case the frequency diversity transmission scheme is determined to be inactivated.
