摘要： A base station apparatus includes a measurement unit, a scheduling unit, and a transmission unit. The measurement unit measures received quality of a reference signal. The scheduling unit provides scheduling information indicating allocation of a radio resource in uplink. The transmission unit transmits a control signal including the scheduling information. After a first packet is transmitted using a first frequency band, a retransmission packet of the first packet is transmitted using a second frequency band other than the first frequency band. The control signal further includes information indicating a difference between received quality in the first frequency band and that in the second frequency band. The retransmission packet is transmitted at a transmission power level determined by adding a transmission power level of the first packet to that corresponding to the difference.
