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.
Claims18
An apparatus comprising:
- communication circuitry configured to perform radio communication via a plurality of frequency channels;
- and
- control circuitry 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 wirelessly transmitted to a terminal, the control information being set by the control circuitry based on a predetermined condition,
- wherein the adjusting the symbol interval in the complex symbol sequence based on the control information comprises adjusting both a length of a data part of the complex symbol sequence and a length of a cyclic prefix attached to the data part of the complex symbol sequence.
A method for performing radio communication by an apparatus via a plurality of frequency channels, the method comprising:
- performing control such that control information for adjusting a symbol interval in a complex symbol sequence, into which a bit sequence is converted, is wirelessly transmitted to a terminal, the control information being set based on a predetermined condition;
- and
- communicating with the terminal via the plurality of frequency channels in accordance with the control information,
- wherein the adjusting the symbol interval in the complex symbol sequence based on the control information comprises adjusting both a length of a data part of the complex symbol sequence and a length of a cyclic prefix attached to the data part of the complex symbol sequence.
A non-transitory computer-readable program product containing instructions for causing a computer to perform a method related to radio communication, the method comprising:
