WIRELESS COMMUNICATION TERMINAL, BASE STATION DEVICE, RESOURCE ALLOCATION METHOD |
摘要 |
A radio communication terminal that increases the ACK/NACK resource utilization efficiency while preventing ACK/NACK collision, and that causes no unnecessary reduction of the PUSCH band in a system that transmits E-PDCCH control information. The radio communication terminal adopts a configuration including a receiving section that receives a control signal including an ACK/NACK index via an enhanced physical downlink control channel (E-PDCCH) transmitted using one configuration from among one or a plurality of configuration candidates, a control section that selects a resource to be used for an ACK/NACK signal of downlink data from among specified resources specified beforehand based on E-PDCCH configuration information used for transmission or reception of the E-PDCCH and the ACK/NACK index, and a transmitting section that transmits the ACK/NACK signal using the selected specified resource. |

1. A radio communication terminal comprising:
a receiver which, in operation, receives control information using a physical resource block (PRB) set that forms an enhanced physical downlink control channel (E-PDCCH), the PRB set including one or more PRBs; a controller which, in operation, monitors a PRB set out of a plurality of predetermined PRB sets and determines an ACK/NACK resource based on both the monitored PRB set and an ACK/NACK Resource Indicator (ARI) included in the E-PDCCH of the monitored PRB set, the ARI indicating the ACK/NACK resource corresponding to the monitored PRB set, and the ARI being independent of an enhanced control channel element (eCCE); and a transmitter which, in operation, transmits ACK/NACK signal using the determined ACK/NACK resource. |
