摘要:
A base station includes a first target receiving power calculation unit that calculates first target receiving power for controlling transmission power based on a path loss and a first parameter used by the user equipment transmitting user data in a predetermined sub-frame through an uplink shared channel to control the transmission power, a difference calculation unit that calculates, based on the path loss, a difference between the first target receiving power and second target receiving power used by the user equipment transmitting the user data through the uplink shared channel at every constant interval to control the transmission power, a second parameter calculation unit that calculates a second parameter by subtracting the difference from the first parameter, and a notification unit that reports the second parameter. The first target receiving power calculation unit calculates the first target receiving power to be greater as the path loss becomes smaller.

A radio base station includes a resource assignment unit for assigning a resource candidate for transmitting a semi-persistent scheduling transmission acknowledgement signal to a first mobile station during a semi-persistent scheduling bearer setting process. The resource candidate for transmitting a semi-persistent scheduling transmission acknowledgement signal is formed by a combination of a frequency direction resource and a code direction resource by which the first mobile station transmits a transmission acknowledgement signal after a predetermined timing from a timing of receiving downlink data, to the downlink data that has been scheduled by semi-persistent scheduling and has been transmitted via a downlink data channel. The resource assignment unit is configured to assign the resource candidate for transmitting a semi-persistent scheduling transmission acknowledgement signal to the first mobile station based on a number of assignments of predetermined resources formed by a combination of a frequency direction resource and a code direction resource.
