Abstract
A terminal (transmission apparatus) is disclosed, which is capable of appropriately configuring processing of a Post-IFFT section in accordance with a communication environment in signal waveform generation. In the terminal, an IFFT section performs IFFT processing on a transmission signal; a control section determines a signal waveform configuration for the transmission signal after the IFFT processing in accordance with a communication environment of the terminal; and the Post-IFFT section performs Post-IFFT processing on the transmission signal after the IFFT processing based on the determined signal waveform configuration.
Claims5
A transmission apparatus comprising:
- an IFFT section that performs IFFT processing on a signal;
- a control section that determines a signal waveform configuration for the signal after the IFFT processing in accordance with a communication environment of the transmission apparatus;
- and
- a Post-IFFT section that performs Post-IFFT processing on the signal after the IFFT processing based on the determined signal waveform configuration,
- wherein the control section determines to apply filtering as the signal waveform configuration when a plurality of transmission apparatuses operate asynchronously;
- and
- the control section determines not to apply filtering as the signal waveform configuration when low latency communication is required of the transmission apparatus, and
- wherein the control section determines to apply neither filtering nor windowing as the signal waveform configuration when a guard band is configured in an adjacent band adjacent to an allocation band allocated for communication of the transmission apparatus, determines to apply neither filtering nor windowing to a center of the allocation band as the signal waveform configuration when no guard band is configured in the adjacent band, and determines to apply filtering or windowing to an edge of the allocation band as the signal waveform configuration when no guard band is configured in the adjacent band.
A communication method comprising:
- performing IFFT processing on a signal;
- determining a signal waveform configuration for the signal after the IFFT processing in accordance with a communication environment of a transmission apparatus;
- and
- performing Post-IFFT processing on the signal after the IFFT processing based on the determined signal waveform configuration,
- wherein the determining includes determining to apply filtering as the signal waveform configuration when a plurality of transmission apparatuses operate asynchronously, and determining not to apply filtering as the signal waveform configuration when low latency communication is required of the transmission apparatus, and
- wherein the determining includes determining to apply neither filtering nor windowing as the signal waveform configuration when a guard band is configured in an adjacent band adjacent to an allocation band allocated for communication of the transmission apparatus, determining to apply neither filtering nor windowing to a center of the allocation band as the signal waveform configuration when no guard band is configured in the adjacent band, and determining to apply filtering or windowing to an edge of the allocation band as the signal waveform configuration when no guard band is configured in the adjacent band.
