Base station apparatus and method for use in mobile communication system

Abstract

One aspect of the present invention relates to a base station apparatus in a mobile communication system, comprising: an acquisition unit configured to receive an uplink signal from a user equipment and acquire channel condition information and an average value of the channel condition information for each of one or more frequency resource blocks; a reference metric calculation unit configured to calculate a reference metric indicative of priority of assignment of the frequency resource blocks to the user equipment based on the channel condition information and the average value of the channel condition information acquired by the acquisition unit; a modification unit configured to modify the reference metric calculated by the reference metric calculation unit with a first parameter to generate a modified metric; a scheduler configured to compare the modified metrics of the individual frequency resource blocks generated by the modification unit and determine an assignment plan of radio resources; and a transmitting unit configured to transmit a downlink signal in accordance with the assignment plan determined by the scheduler, wherein the modification unit modifies the reference metric with the first parameter, the first parameter having a first value for a predefined first frequency resource block and a second value for a predefined second frequency resource block if the user equipment belongs to a group differentiated based on a path loss.
