Patent ID: 8301951

Claim:
A base station having a retransmission function for transmitting a retransmission packet when an error is detected in a transmission packet which is transmitted to a mobile station on a frequency band including multiple resource blocks, comprising: a channel-condition-based scheduling unit configured to schedule a transmission packet or a retransmission packet by allocating a radio resource to the transmission packet or the retransmission packet based on a channel condition for the mobile station; a persistent scheduling unit configured to schedule a transmission packet or a retransmission packet by allocating a radio resource to the transmission packet or the retransmission packet according to a predetermined cycle and a predetermined frequency allocation pattern; a control unit configured to avoid contention between the radio resource allocated to the transmission packet or the retransmission packet by the channel-condition-based scheduling unit and the radio resource allocated to the transmission packet or the retransmission packet by the persistent scheduling unit, and a non-transitory transmitting unit configured to transmit the transmission packet or the retransmission packet to the mobile station as a result of control by the control unit.
