1. An apparatus comprising:
circuitry configured to
perform radio communication;
transmit to an external apparatus through the radio communication control information regarding a resource to be used in the radio communication:
select a filter application unit from a plurality of candidates, wherein each of the plurality of candidates comprises a subcarrier bandwidth and a symbol length, and the filter application unit represents a minimum time-frequency unit to which a filter is applied;
divide a bit stream into a plurality of units, each of the plurality of units having a size of the selected filter application unit;
apply the filter to each of the plurality of units to generate a plurality of filtered units; and
add the plurality of filtered units to generate a signal for transmission,
wherein the control information is transmitted to the external apparatus, and the control information is used by the external apparatus to set the width of a guard band around the signal.
