Mobile station apparatus and communication method

摘要

A mobile station (MS) receives, from a base station (BS), information which is used to assign a PUSCH resource; transmits uplink control information using a single PUCCH resource in case that the PUSCH resource is not assigned and a plurality of PUCCH resources is assigned; transmits the uplink control information using the PUSCH resource assigned on a first uplink component carrier (UCC) in case that the PUSCH resource is assigned on the first UCC, the first UCC is used for transmitting the uplink control information using the single PUCCH resource in case that the PUSCH resource is not assigned and the plurality of PUCCH resources is assigned; and receives the uplink control information using the PUSCH resource assigned on a second UCC in case that the PUSCH resource is not assigned on the first UCC but the PUSCH resource is assigned on the second UCC.

主权项

1. A mobile station apparatus which is configured to communicate with a base station apparatus using a plurality of component carriers, the mobile station apparatus comprising:
a reception unit configured to receive, from the base station apparatus, information which is used to assign a physical uplink shared channel resource; and a transmission unit configured to transmit, to the base station apparatus, uplink control information using a single physical uplink control channel resource in case that the physical uplink shared channel resource is not assigned and a plurality of physical uplink control channel resources is assigned, wherein the transmission unit is further configured to transmit, to the base station apparatus, the uplink control information using the physical uplink shared channel resource assigned on a first uplink component carrier in case that the physical uplink shared channel resource is assigned on the first uplink component carrier, the first uplink component carrier is used for transmitting the uplink control information using the single physical uplink control channel resource in case that the physical uplink shared channel resource is not assigned and the plurality of physical uplink control channel resources is assigned, and the transmission unit is further configured to transmit, to the base station apparatus, the uplink control information using the physical uplink shared channel resource assigned on a second uplink component carrier in case that the physical uplink shared channel resource is not assigned on the first uplink component carrier but the physical uplink shared channel resource is assigned on the second uplink component carrier.
