Problems solved by technology

[0014] However, in the prior art, there is a problem that the mobile station apparatus cannot transmit data (information) to the base station apparatus using a plurality of PUCCHs in the same subframe (simultaneous transmission of a plurality of PUCCHs), or use PUSCH and PUCCH in the same subframe. PUCCH transmits data (information) to the base station (simultaneous transmission of PUSCH and PUCCH)

no. 1 Embodiment approach

[0077] Next, a first embodiment in a mobile communication system using the base station apparatus 100 and the mobile station apparatus 200 will be described. In the first embodiment, the base station apparatus 100 transmits a message for instructing the mobile station apparatus 200 to use a single physical uplink control channel (PUCCH) to transmit uplink control information in one or more specific uplink carrier components. information, and when the mobile station apparatus 200 receives the information from the base station apparatus 100, even if a plurality of PUCCHs are assigned to one or more specific uplink carrier components indicated by the base station apparatus 100, Uplink control information is also transmitted using a single PUCCH. That is, regardless of whether a plurality of PUCCHs are assigned to one or more specific uplink carrier components indicated by the base station apparatus 100, uplink control information is transmitted using a single PUCCH.

Abstract

A mobile station apparatus which communicates with a base station apparatus using a plurality of component carriers, transmits uplink control information to the base station apparatus using a single physical uplink control channel in a plurality of uplink component carriers, regardless of whether or not a plurality of physical uplink control channels is assigned by the base station apparatus and, when each physical uplink shared channel of the plurality of uplink component carriers including a first uplink component carrier on which the uplink control information is transmitted using the physical uplink control channel is assigned in the same subframe by the base station apparatus, transmits the uplink control information to the base station apparatus using the physical uplink shared channel of the first uplink component carrier.

Description

technical field [0001] The present invention relates to a mobile station device that communicates with a base station device using a plurality of component carriers, and a communication method thereof. Background technique [0002] 3GPP (Third Generation Partnership Project) researches or formulates specifications for mobile communication systems based on networks that have developed W-CDMA (Wideband Code Division Multiple Access) and GSM (Global System for Mobile Communications) plan. In 3GPP, the W-CDMA system is being standardized as the third-generation cellular mobile communication system, and services are starting sequentially. In addition, HSDPA (High Speed ​​Downlink Packet Access), which further increases the communication speed, is also being standardized and started serving. In 3GPP, the evolution of the third-generation wireless access technology (hereinafter referred to as "LTE (Long Term Evolution)" or "EUTRA (Evolved Universal Terrestrial Radio Access)") is ...
