Abstract
To achieve system efficiency by avoiding inefficient resource assignment of “Carrier Segment/Extension Carrier”. A mobile station UE according to the present invention includes a control signal reception unit 11 configured to receive a downlink control signal for notifying the transmission of downlink data from a radio base station eNB, and a reception unit 13 configured to receive the downlink data based on the received downlink control signal, wherein the downlink control signal includes bits indicating the assignment or non-assignment of the “Carrier Segment/Extension Carrier”, in addition to resource assignment information “RB assignment information of the normal “Component Carrier”.
Claims6
A mobile station, which is configured to perform downlink communication with respect to a radio base station using a normal carrier and an additional carrier, comprising:
- a control signal reception unit configured to receive a downlink control signal for notifying transmission of downlink data from the radio base station;
- and
- a reception unit configured to receive the downlink data based on the received downlink control signal, wherein
- the downlink control signal includes a bit indicating assignment or non-assignment of the additional carrier, in addition to resource assignment information of the normal carrier, and designates different numbers of resource blocks for each bit indicating assignment or non-assignment of the additional carrier defined for each of the additional carrier.
A mobile station, which is configured to perform uplink communication with respect to a radio base station using a normal carrier and an additional carrier, comprising:
- a control signal reception unit configured to receive a downlink control signal for instructing transmission of uplink data from the radio base station;
- and
- a transmission unit configured to transmit the uplink data based on the received downlink control signal, wherein
- the downlink control signal includes a bit indicating assignment or non-assignment of the additional carrier, in addition to resource assignment information of the normal carrier, and designates different numbers of resource blocks for each bit indicating assignment or non-assignment of the additional carrier defined for each of the additional carrier.
A radio base station, which is configured to perform downlink communication with respect to a mobile station using a normal carrier and an additional carrier, comprising:
- a control signal transmission unit configured to transmit a downlink control signal for notifying transmission of downlink data to the mobile station;
- and
- a transmission unit configured to transmit the downlink data, wherein
- the downlink control signal includes a bit indicating assignment or non-assignment of the additional carrier, in addition to resource assignment information of the normal carrier, and designates different numbers of resource blocks for each bit indicating assignment or non-assignment of the additional carrier defined for each of the additional carrier.
A radio base station, which is configured to perform uplink communication with respect to a mobile station using a normal carrier and an additional carrier, comprising:
- a control signal transmission unit configured to transmit a downlink control signal for instructing transmission of uplink data to the mobile station;
- and
- a configured to receive the uplink data, wherein
- the downlink control signal includes a bit indicating assignment or non-assignment of the additional carrier, in addition to resource assignment information of the normal carrier, and designates different numbers of resource blocks for each bit indicating assignment or non-assignment of the additional carrier defined for each of the additional carrier.
A mobile communication method in a mobile station, which performs downlink communication with respect to a radio base station using a normal carrier and an additional carrier, comprising:
- a step of receiving a downlink control signal for notifying transmission of downlink data from the radio base station;
- and
- a step of receiving the downlink data based on the received downlink control signal, wherein
- the downlink control signal includes a bit indicating assignment or non-assignment of the additional carrier, in addition to resource assignment information of the normal carrier, and designates different numbers of resource blocks for each bit indicating assignment or non-assignment of the additional carrier defined for each of the additional carrier.
A mobile communication method in a mobile station, which performs uplink communication with respect to a radio base station using a normal carrier and an additional carrier, comprising:
- a step of transmitting a downlink control signal for instructing transmission of uplink data from the radio base station;
