Abstract
[Object] To adaptively adjust a symbol interval in accordance with a communication environment. [Solution] An apparatus including: a communication unit configured to perform radio communication; and a control unit configured to perform control such that control information for adjusting a symbol interval in a complex symbol sequence into which a bit sequence is converted is transmitted from the communication unit to a terminal, the control information being set on a basis of a predetermined condition.

An apparatus comprising:
- a transceiver;
- and
- control circuitry operatively connected to the transceiver and configured to transmit control information to a terminal, the control information containing a single element for adjusting both:
- a characteristic of each symbol of a plurality of symbols, each symbol comprising a complex symbol sequence produced from a corresponding bit sequence, and
- a length of a cyclic prefix of each symbol of the plurality of symbols, transceive the plurality of symbols with the terminal according to the control information,
- wherein control information is notified by radio resource control (RRC) information.
