Abstract
There is provided an apparatus including a communication unit that performs radio communication and a control unit that controls transmission from the communication unit to a terminal by narrowing at least one of a symbol interval of a complex symbol sequence in a time direction and a subcarrier interval of the complex symbol sequence in a frequency direction, the complex symbol sequence being converted from a bit sequence, the symbol interval and the subcarrier interval being set on a basis of a predetermined condition.
Claims19
An apparatus, comprising:
- a controller configured to generate a complex symbol sequence based on a bit sequence;
- and
- a radio communication interface configured to transmit the complex symbol sequence via radio communication, wherein
- the controller is further configured to:
- set a symbol interval of the complex symbol sequence and a subcarrier interval of the complex symbol sequence based on a specific condition;
- control the transmission of the complex symbol sequence from the radio communication interface to a terminal based on at least one of the symbol interval of the complex symbol sequence in a time direction or the subcarrier interval of the complex symbol sequence in a frequency direction is narrower than a Nyquist interval;
- and
- set one of a narrowing amount of the symbol interval or a narrowing amount of the subcarrier interval for one of each cell of a plurality of cells or each component carrier of a plurality of component carriers based on information associated with a signaling operation of a higher layer of the apparatus.
