Abstract
A wireless communication technology which realizes high-speed transmission while making effective use of existing frequency bands. A wireless communication apparatus includes a communication unit to perform a wireless communication with a target communication device by simultaneously using a plurality of carrier frequency bands each of which has a specified bandwidth and is discontinuous between each carrier frequency-band interval.
Claims10
A wireless terminal, comprising a communication unit configured to perform wireless communication to one or more target communication devices by simultaneously using a plurality of carrier frequency bands each having a specified bandwidth, the plurality of carrier frequency bands being discontinuous therebetween.
A wireless communication method, comprising:
- performing wireless communication to one or more target communication devices by simultaneously using a plurality of carrier frequency bands each having a specified bandwidth, the plurality of carrier frequency bands being discontinuous therebetween.
The wireless communication method according to claim 8, wherein the performing wireless communication includes:
- generating a first baseband multicarrier signal based on a radio signal of a first carrier frequency band;
- generating a second baseband multicarrier signal based on a radio signal of a second carrier frequency band;
- and
- generating a first decoded signal based on the first baseband multicarrier signal corresponding to a bandwidth of a first carrier frequency band among the plurality of carrier frequency bands, and a second decoded signal based on the second baseband multicarrier signal corresponding to a bandwidth of a second carrier frequency among the plurality of carrier frequency bands.
The wireless communication method according to claim 9, wherein the generating the first-and-second decoded signals includes:
- performing FFT processing on the first baseband multicarrier signal by performing FFT processing based on a FFT size corresponding to the bandwidth of the first carrier frequency band;
- and
- performing FFT processing on the second baseband multicarrier signal by performing FFT processing based on a FFT size corresponding to the bandwidth of the second carrier frequency band.
The wireless communication method according to claim 9, wherein the generating the first-and-second baseband multicarrier signals further including:
- assigning the first baseband multicarrier signal and the second baseband multicarrier signal which are input from the generating the first baseband multicarrier signal based on the radio signal of the first carrier frequency band or the generating the second baseband multicarrier signal based on the radio signal of the second carrier frequency band;
- and
- mapping, based on the assignment result, the first baseband multicarrier signal and the second baseband multicarrier signal to a predetermined interface signals.
