Patent ID: 8600396

Claim:
A radio scheduling apparatus in a radio communication system in which a modulation scheme is selected in accordance with radio quality, the radio scheduling apparatus comprising: a radio quality acquisition section that acquires radio quality information indicative of radio quality for each mobile station; and a scheduling section that determines the degree of urgency for assigning a radio channel according to the radio quality, based on the radio quality information acquired by the radio quality acquisition section, and preferably assigns a radio channel to a mobile station having a high degree of urgency; wherein when an index for the mobile station is defined as (k), the predicted value of the radio quality is defined as γ pred,k , and the instantaneous radio quality is defined as γk, the scheduling section uses a predetermined parameter (u) to calculate an evaluation function: ⁢ C k = γ k u γ pred , k [ Expression ⁢ ⁢ 1 ] and assigns a radio resource to a mobile station having the largest evaluation function value.
