Abstract
[Object] To provide a mechanism capable of accommodating legacy terminals not supporting GFDM in addition to terminals supporting GFDM when GFDM is introduced. [Solution] A device includes: a setting unit configured to variably set at least one of an interval between subcarriers and a time length of a subsymbol included in a unit resource constituted by one or more subcarriers or one or more subsymbols; and a transmission processing unit configured to perform filtering for every predetermined number of subcarriers.
Claims31
A device, comprising:
- circuitry configured to
- variably set at least one of an interval between subcarriers and a time length of a subsymbol included in a unit resource constituted by one or more subcarriers or one or more subsymbols;
- and
- a transmission processing unit configured to perform filtering for every predetermined number of subcarriers, wherein
- the circuitry applies a filter in which a filter coefficient with a sharp band limitation characteristic is set for a small interval between subcarriers, and applies a filter in which a filter coefficient with a gentle band limitation characteristic is set for a large interval between subcarriers.
2 more elements
A device, comprising:
- circuitry configured to set a non-use frequency domain in a unit resource constituted by one or more subcarriers or one or more subsymbols and variably set at least one of an interval between the subcarriers or a time length of the subsymbol in use frequency domains other than the non-use frequency domain, wherein
- the circuitry applies a filter in which a filter coefficient with a sharp band limitation characteristic is set for a small interval between the subcarriers, and applies a filter in which a filter coefficient with a gentle band limitation characteristic is set for a large interval between the subcarriers.
A method, comprising:
- variably setting at least one of an interval between subcarriers and a time length of a subsymbol included in a unit resource constituted by one or more subcarriers or one or more subsymbols;
- and
- performing, by a processor, filtering for every predetermined number of subcarriers, the filtering including applying a filter in which a filter coefficient with a sharp band limitation characteristic is set for a small interval between subcarriers, and applying a filter in which a filter coefficient with a gentle band limitation characteristic is set for a large interval between subcarriers.
