Abstract

When the mobile station apparatus transmits the physical random access channel to the base station apparatus in a plurality of cells, the transmission power of the physical uplink channel is efficiently controlled. In a mobile station apparatus that performs a random access procedure in a plurality of cells with a base station apparatus, downlink control information including a transmission power control command for a physical uplink control channel is received from the base station apparatus, and is performed by the base station apparatus. calculating a parameter by accumulating the value indicated by the transmission power control command, using the parameter to set the transmission power of the physical uplink control channel, and transmitting the physical uplink control channel to the base station apparatus in a specific cell , when a random access response for the specific cell is received from the base station apparatus, resetting the accumulation of the parameters.

Description

technical field [0001] The present invention relates to a base station device, a mobile station device, a wireless communication method, and an integrated circuit. Background technique [0002] In the 3rd Generation Partnership Project (3rd Generation Partnership Project: 3GPP), the wireless access mode of cellular mobile communication and the evolution of wireless networks (hereinafter referred to as "Long Term Evolution, Long Term Evolution (LTE)" or "Evolved Universal Terrestrial Radio Access, Evolved Universal Terrestrial Radio Access (EUTRA)"). In LTE, an Orthogonal Frequency Division Multiplexing (OFDM) method of multi-carrier transmission is used as a communication method for wireless communication (downlink) from a base station apparatus to a mobile station apparatus. In addition, as a communication method of wireless communication (uplink) from the mobile station apparatus to the base station apparatus, an SC-FDMA (Single-Carrier Frequency Division Multiple Access)...
