Abstract

A wireless base station apparatus notifies a mobile wireless terminal apparatus of a channel to be used to transmit a response signal of channel assignment by a mapping pattern of channel assignment information transmitted on a plurality of bands.

Claims

1. A wireless transmission apparatus which assigns channels of a plurality of bands to a wireless reception apparatus, notifies the wireless reception apparatus of channel assignment information of each band, and performs data transmission via the assigned channels of the plurality of bands, comprising:

a transmission unit which transmits the channel assignment information of each band to the wireless reception apparatus via a corresponding band; and

a reception unit which receives a response signal from the wireless reception apparatus via a channel corresponding to, out of the bands used by the transmission unit to transmit the channel assignment information, a band predetermined for the wireless reception apparatus.

2. A wireless reception apparatus which receives channel assignment information, recognizes channels of a plurality of bands assigned by a wireless transmission apparatus, and performs data reception via the channels of the plurality of bands, comprising:

a reception unit which receives a plurality of items of channel assignment information transmitted via the plurality of bands, respectively; and

a transmission unit which transmits a response signal to the wireless transmission apparatus via a channel corresponding to, out of the bands used by the reception unit for reception, a band predetermined for the wireless reception apparatus.

3. A wireless communication method of causing a wireless transmission apparatus to assign channels of a plurality of bands to a wireless reception apparatus, notifying the wireless reception apparatus of channel assignment information of each band, and performing data transmission via the assigned channels of the plurality of bands, comprising steps of:

causing the wireless transmission apparatus to transmit the channel assignment information of each band to the wireless reception apparatus via a corresponding band;

causing the wireless reception apparatus to receive a plurality of items of channel assignment information transmitted via the plurality of bands, respectively;

causing the wireless reception apparatus to transmit a response signal to the wireless transmission apparatus via a channel corresponding to, out of the bands used for reception in the step of causing the wireless reception apparatus to receive a plurality of items of channel assignment information, a band predetermined for the wireless reception apparatus; and

causing the wireless transmission apparatus to receive the response signal via a channel corresponding to, out of the bands used to transmit the channel assignment information in the step of causing the wireless transmission apparatus to transmit the channel assignment information, a band predetermined for the wireless reception apparatus.
