Abstract
A radio base station (1) for use in a wireless communication system comprises—a scheduling unit (9) arranged to schedule at least one user terminal to which to transmit in each subframe and—a power allocation unit (11) arranged to allocate a first amount of power to be used for the at least one user terminal in each subframe, a transmitter (5) arranged to transmit a transport block in a subframe to a number of user terminals (3) in the wireless communication system in accordance with said scheduling and power allocation. The radio base station further comprises—a correction unit (5) arranged to determine, after scheduling has been performed for a chosen subframe, if there is excess power in the chosen subframe that has not been allocated to any user terminal and if so allocate at least a first part of the excess power to at least one user terminal scheduled in the subframe. The excess power is used when transmitting in the subframe.
