Abstract
To provide a radio base station apparatus, a mobile terminal apparatus and a radio access method that support each of a plurality of mobile communication systems when the plurality of mobile communication systems coexists, the configuration is provided in which in transmission in a mobile communication system having a system band comprised of a plurality of component carriers, the transmission data is subjected to frequency hopping in a single component carrier in a subframe, while being subjected to frequency hopping over mutually different component carriers in prior and subsequent subframes.
Claims21
A radio base station apparatus comprising:
- a transmitting section configured to transmit downlink transmission data using a system band comprised of a plurality of base frequency blocks;
- and
- a hopping section configured to apply frequency hopping for the downlink transmission data to be transmitted by the transmitting section over the plurality of base frequency blocks.
A mobile terminal apparatus comprising:
- a transmission section configured to transmit uplink transmission data using a system band comprised of a plurality of base frequency blocks;
- and
- a hopping section configured to apply frequency hopping for the uplink transmission data to be transmitted by the transmission section over the plurality of base frequency blocks.
A radio access method comprising:
- transmitting transmission data using a system band comprised of a plurality of base frequency blocks;
- and
- applying frequency hopping for the transmission data over the plurality of base frequency blocks.
