摘要： A base station apparatus includes a scheduler configured to schedule assignment of radio resources based on a scheduling coefficient for one or more user equipments, a control signal generation unit configured to generate a control signal including reporting indication information for indicating whether the user equipment is to report downlink channel state information and scheduling grant information for indicating the scheduled assignment of the radio resources and a transmitting unit configured to transmit the control signal in a downlink. A cumulative value is calculated for each of the user equipments. The reporting indication information transmitted to a user equipment, whose cumulative value reaches a predefined value, indicates that the user equipment is to report the downlink channel state information. The cumulative value is updated if the scheduling coefficient satisfies a predefined condition.
