摘要 |
In a case that a mobile station apparatus transmits a physical random access channel to a base station apparatus in a plurality of cells, it is possible to efficiently control transmission power of a physical uplink channel. A mobile station apparatus which performs a random access procedure with a base station apparatus in a plurality of cells, receives downlink control information including a transmission power control command for a physical uplink control channel from the base station apparatus, calculates a parameter by accumulating a value indicated by the transmission power control command, sets transmission power of a physical uplink control channel by using the parameter, transmits the physical uplink control channel to the base station apparatus in a specific cell, and resets accumulated parameter, when a random access response for the specific cell is received from the base station apparatus. |
