| 摘要 | When a mobile station apparatus capable of being connected to a base station apparatus by using a plurality of frequency bands performs an uplink transmission, the mobile station apparatus selects the optimum combination among the combinations of a plurality of frequency bands and uplink transmission methods, and performs the uplink transmission. The mobile station apparatus aggregates a plurality of cells to connect the same to a base station apparatus and requests, from the base station apparatus, an uplink radio resource required to transmit uplink data. The mobile station apparatus selects, based on a first condition, an uplink for making a radio resource request using a random access channel from the plurality of cells, and selects, based on a second condition, either the radio resource request using the random access channel or the transmission of uplink data using an uplink radio resource common to other mobile station apparatuses. | ||

| 主权项 | 1. A mobile station apparatus using a plurality of cells aggregated to connect to a base station apparatus, the mobile station apparatus comprising: a circuitry configured to and/or programmed to determine, a cell from among the plurality of cells aggregated, the cell determined based on first information which is transmitted from the base station apparatus to the mobile station apparatus by a Radio Resource Control (RRC) message, the first information including a transmission setting of a random access channel on an uplink of the cell, the cell used to transmit a request an uplink radio resource which is required to transmit uplink data, andthe random access channel for the radio resource request based on second information not including an uplink control channel resource for the radio resource request, the second information being transmitted from the base station apparatus to the mobile station apparatus by the RRC message. | ||
