Abstract:
A radio base station including a user equipment configured to execute radio communication with a base station device in a mobile communication system. The user equipment includes a control signal reception unit configured to receive a control signal providing instructions to transmit an uplink signal and an uplink signal transmission unit configured to transmit the uplink signal to the base station device on a basis of the control signal, the uplink signal transmission unit is configured to set a maximum value of transmission power of the uplink signal to be smaller than rated power defined by the mobile communication system on a basis of at least one of a parameter notified by the control signal and a number of transmission antennas or transmitters used for transmission of an uplink signal.
