MOBILE COMMUNICATION SYSTEM, BASE STATION APPARATUS, MOBILE STATION APPARATUS, AND MOBILE COMMUNICATION METHOD

摘要

A mobile station apparatus that includes a controller that reduces transmission power in case that data is transmitted simultaneously and a transmission circuit that simultaneous transmits said data using a plurality of channels, where the plurality of channels consists of at least one physical uplink control channel and at least one physical uplink shared channel. The transmission circuit of the mobile station apparatus also transmit hybrid automatic repeat request control information on said at least one physical uplink shared channel and also transmits channel state information on said at least one physical uplink control channel.

1. A mobile station apparatus configured to communicate with a base station apparatus using a plurality of downlink component carriers, the mobile station apparatus comprising:
receiving circuitry configured to
receive, from the base station apparatus, a radio resource control signal including first information used for configuring a first physical uplink control channel resource, the first physical uplink control channel resource being used for transmission of channel state information, andreceive, from the base station apparatus, a physical downlink control channel used for indicating a second physical uplink control channel resource, the second physical uplink control channel resource being used for transmission of HARQ (Hybrid Automatic Repeat Request) control information, and transmitting circuitry configured to
transmit in a first subframe, to the base station apparatus, the channel state information using the first physical uplink control channel resource, andtransmit in a second subframe, to the base station apparatus, the HARQ control information using the second physical uplink control channel resource, wherein the transmitting circuitry is configured to transmit in a third subframe where the transmission of the channel state information collides with the transmission of the HARQ control information, to the base station apparatus, the channel state information and the HARQ control information using the second physical uplink control channel resource in a case that the second physical uplink control channel resource is indicated by using the physical downlink control channel.
