Patent number: 8406244Abstract: A base station apparatus includes a buffer for temporarily storing data to be transmitted to a mobile station in a data queue corresponding to the mobile station, and a controller for performing control of retransmitting data whose retransmission is requested by a mobile station by selecting the data from a data queue corresponding to the mobile station. When retransmitting data to a mobile station, if the data storage amount in a data queue corresponding to the mobile station is equal to or larger than a predetermined threshold value, the controller performs control of making the error resistance on wireless propagation higher than that of the last data transmission to the mobile station. This makes it possible to increase the retransmission data reception success probability of a mobile station, and suppress the occurrence of retransmission control by an upper layer.Type: GrantFiled: March 26, 2007Date of Patent: March 26, 2013Assignee: NEC CorporationInventor: Kenki Takagi
