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.

Abstract: [Problem] To proposed a modulation mechanism for enabling achieving further enhancement in the resource efficiency.
[Solution] A transmission device includes a converting unit that converts a first-type bit sequence and a second-type bit sequence into a complex signal point sequence. Each of a plurality of complex signal points included in the complex signal point sequence represents an element of one of a plurality of complex signal point sets. In the complex signal point sequence, the applicable patterns of the plurality of complex signal point sets correspond to the first-type bit sequence in a plurality of predetermined combinations of candidates for the first-type bit sequence and the applicable patterns. Each complex signal point included in the complex signal point sequence corresponds to the second-type bit sequence.

Abstract: A mechanism of modulation in a more appropriate spatial domain is to be provided.
A transmission device includes a signal processing unit that applies a precoding matrix on the basis of a first bit sequence to a complex signal point sequence converted from a second bit sequence, and the precoding matrix applied to the complex signal point sequence corresponds to the first bit sequence in a predetermined combination of a first bit sequence candidate and each element of a set of precoding matrices.

Abstract: An apparatus that can make a success of demodulation on the reception side even if the restrictions on the resource setting are lifted. The apparatus includes: a processing unit configured to variably set at least any of a number of subcarriers or a number of subsymbols included in a unit resource including one or more subcarriers or one or more subsymbols, and set a filter coefficient that is applied in accordance with different rules which depend on whether the number of subsymbols included in the unit resource is an even number or an odd number.
