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

Provided is a mobile station device that communicates with a base station device using multiple component carriers, wherein multiple items of uplink control information are transmitted to the aforementioned base station device, using a single physical uplink control channel within the multiple uplink component carriers, regardless of whether multiple physical uplink control channels are assigned by the aforementioned base station device. When physical uplink shared channels within the aforementioned multiple uplink component carriers, including a first uplink component carrier with which the aforementioned uplink control information is transmitted using the aforementioned physical uplink control channel, are assigned the same sub-frame by the aforementioned base station device, the mobilestation device will transmit the aforementioned uplink control information to the aforementioned base station device, using the physical uplink shared channel within the aforementioned 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 ...
